class=\"wp-block-paragraph\">Inventory valuation is the accounting process of assigning a monetary value to inventory held by a business. For manufacturers, inventory includes more than just goods between purchase and sale \u2013 it\u2019s&nbsp;raw materials&nbsp;awaiting use, components and products currently in production, and finished goods made to stock, awaiting sale.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Inventory valuation determines two important numbers: how much unsold inventory remains on the balance sheet as a current asset out of total goods available for sale, and how much inventory cost is recognized as <a href=\"https:\/\/www.mrpeasy.com\/blog\/calculating-cost-of-goods-sold-in-manufacturing\/\" target=\"_blank\" rel=\"noreferrer noopener\">cost of goods sold (COGS)<\/a> when products are sold. More on those terms below.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are different ways to go about this. In this article, we\u2019ll explain the four primary methods used for assigning value to your inventory: First-In, First-Out (FIFO), Last-In, First-Out (LIFO), weighted average cost (WAC), and specific identification (SI). Which method makes sense depends on the type of inventory you carry, how your production works, the accounting standards you follow, and how accurately individual inventory costs can be tracked.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Understanding_inventory_terminology\"><\/span>Understanding inventory terminology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Before we go into the different inventory valuation methods, here\u2019s a refresher on what inventory value actually consists of. Inventory costs go beyond the market price of supplies. They also include holding and moving expenditure, overheads, and, for manufacturers, all the costs incurred in turning it into finished products.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Inventory costs typically include:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the purchase price of raw materials and components,<\/li>\n\n\n\n<li>freight, import duties, and other directly attributable purchasing costs,<\/li>\n\n\n\n<li>direct production labor,<\/li>\n\n\n\n<li>manufacturing overhead,<\/li>\n\n\n\n<li>everything else required to bring inventory to its current condition and location.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Raw materials, WIP, and finished goods<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Within the production process, a heap of value is added to purchases. Manufacturing inventory generally moves through three main stages.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Raw materials<\/strong> are purchased materials and components that have not yet entered production. Their value is generally based on their acquisition cost, including expenses related to the purchasing process.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.mrpeasy.com\/blog\/work-in-process-inventory-accounting\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Work in process (WIP)<\/strong><\/a> consists of products that have already entered production. Some value-adding work has been done on them, but they aren\u2019t yet finished. Their value includes the materials already consumed, plus labor and manufacturing overhead applied up to that point.<\/li>\n\n\n\n<li><strong>Finished goods<\/strong> are completed products ready for sale. Their inventory value includes all the costs accumulated during production.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Suppose a manufacturer uses $20 worth of materials to make a product, adds $8 in direct labor, and allocates $4 in manufacturing overhead. The finished product has accumulated $32 in manufacturing costs. Accurately tracking the movement of this value from materials through WIP to finished goods is the main reason why inventory valuation is both more complicated and more important for manufacturers than for most retailers or distributors.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Also, check out our guide on how to allocate <\/em><a href=\"https:\/\/www.mrpeasy.com\/blog\/manufacturing-overhead\/\" target=\"_blank\" rel=\"noreferrer noopener\"><em>manufacturing overhead<\/em><\/a><em>.<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Inventory value, COGS, and gross profit<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Inventory valuation directly affects both your balance sheet and your income statement. When inventory is still in stock, its cost remains an asset. Once the finished goods are sold, their inventory cost becomes <strong>cost of goods sold<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the accounting-period level, the relationship can be expressed simply:<\/p>\n\n\n\n<p class=\"has-text-align-center has-medium-font-size wp-block-paragraph\"><strong>Beginning inventory + inventory added \u2212 ending inventory = COGS<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gross profit is then:<\/p>\n\n\n\n<p class=\"has-text-align-center has-medium-font-size wp-block-paragraph\"><strong>Sales revenue \u2212 COGS = gross profit<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is why two businesses with identical purchases and sales can report different gross profits if they apply different inventory valuation methods. During periods of changing material prices, this difference can become quite substantial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Read more about <\/em><a href=\"https:\/\/www.mrpeasy.com\/blog\/manufacturing-accounting\/\" target=\"_blank\" rel=\"noreferrer noopener\"><em>manufacturing accounting<\/em><\/a><em> in our guide.<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Cost flow vs. physical inventory flow<\/h3>\n\n\n<div class=\"banner-v2\">\n    <p class=\"banner-v2__desc\">Automatically track your inventory with MRPeasy<\/p>\n    <a class=\"banner-v2__link\" href=\"https:\/\/www.mrpeasy.com\/sign-up\/\" target=\"_blank\" data-ga-event=\"blog_signup_banner_blue\">Try for free<\/a>\n<\/div>\t\t<style>.banner-v2 {\n    float: right;\n    display: flex;\n    flex-direction: column;\n    justify-content: center;\n    align-items: center;\n    padding: 40px 32px;\n    gap: 16px;\n    width: 356px;\n    height: 205px;\n    background: linear-gradient(199.68deg, #6084E5 13.17%, #5FA7DD 82.1%);\n    border-radius: 4px;\n    margin-left: 12px;\n    margin-bottom: 12px;\n    margin-top: 15px;\n}\n\n@media (max-width: 767.98px) {\n    .banner-v2 {\n         width: 100%;\n         height: 173px;\n         margin-bottom: 0;\n         margin-left: 0;\n    }\n}\n\n.single__content p.banner-v2__desc {\n    margin: 0 !important;\n}\n\np.banner-v2__desc {\n    width: 292px;\n    font-style: normal;\n    font-weight: 700;\n    font-size: 22px;\n    line-height: 29px !important;\n    text-align: center;\n    color: #FFFFFF;\n    margin: 0 !important;\n    order: 0 !important;\n}\n\n.single__content a.banner-v2__link {\n    color: #FFFFFF !important;\n}\n\n.single__content a.banner-v2__link:hover {\n    color: #003557 !important;\n}\n\na.banner-v2__link {\n    display: flex;\n    justify-content: center;\n    align-items: center;\n    width: 181px;\n    height: 51px;\n    padding: 18px 0;\n    border-radius: 4px;\n    background: #003557;\n    font-weight: 700;\n    font-size: 16px;\n    color: #FFFFFF !important;\n    text-decoration: none !important;\n    order: 1 !important;\n}\n\n.banner-v2__link:hover {\n    background: white;\n    color: #003557 !important;\n}<\/style>\n\t\t\n\n\n<p class=\"wp-block-paragraph\">A common misconception is that a company&#8217;s chosen&nbsp;inventory valuation method&nbsp;also determines the order in which physical items should be picked from the shelf. As you\u2019ll see below, methods like FIFO and LIFO assign inventory value based on the cost differences of similar inventory items, depending on the order in which they were procured (assuming they were purchased at different prices).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, when using the FIFO method, accounting assumes that the oldest inventory \u2013 the one you procured first- is sold or gets used first. But in reality, this is a <strong>cost-flow assumption <\/strong>and doesn\u2019t mean that warehouse workers have to necessarily pick the physically oldest unit when an item of that type is sold or required. FIFO simply designates which <a href=\"https:\/\/www.mrpeasy.com\/blog\/inventory-costs\/\" target=\"_blank\" rel=\"noreferrer noopener\">inventory costs<\/a> are assigned to the goods sold or consumed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This distinction matters a lot because the physical flow of inventory should often be governed by totally different considerations, like expiration dates, batch traceability, quality requirements, warehouse layout, or customer specifications. None of which necessarily matters to accounting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Periodic vs. perpetual valuation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A final note. Inventory can also be accounted for using either a periodic or perpetual inventory system. These are not separate valuation methods, but different types of systems that determine how often inventory records are updated.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In a <strong>periodic inventory system<\/strong>, inventory balances are calculated at specific intervals, usually using a physical inventory count. COGS is then calculated for the accounting period after the fact.<\/li>\n\n\n\n<li>A <strong>perpetual inventory system<\/strong> continuously records inventory movements as goods are purchased, consumed, produced, adjusted, or sold. The COGS stays accurate throughout the period. Perpetual systems rely on automated <a href=\"https:\/\/www.mrpeasy.com\/inventory-management-software\/\" target=\"_blank\" rel=\"noreferrer noopener\">inventory management software<\/a>, although physical counts are also used to reconcile differences and confirm accuracy.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_4_inventory_valuation_methods\"><\/span>The 4 inventory valuation methods<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The four main methods each approach inventory costs differently. To make them easier to compare, we\u2019ll use the same basic example for each:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A manufacturer purchases 300 identical components in three batches:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>100 units at $10 each;<\/li>\n\n\n\n<li>100 units at $12 each;<\/li>\n\n\n\n<li>100 units at $15 each.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The total inventory cost is $3,700. The company then consumes (sells or allocates to production) 150 units.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">FIFO<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>First-In, First-Out (FIFO)<\/strong> assumes that the oldest inventory costs are assigned to goods sold or consumed first. The most recently purchased inventory, therefore, remains in stock.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">FIFO example<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Using our example, the first 150 units consist of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>100 units \u00d7 $10 = $1,000;<\/li>\n\n\n\n<li>50 units \u00d7 $12 = $600.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">COGS is therefore <strong>$1,600<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The remaining inventory is:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>50 units \u00d7 $12 = $600;<\/li>\n\n\n\n<li>100 units \u00d7 $15 = $1,500.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Ending inventory value is <strong>$2,100<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">When it makes sense<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">FIFO is widely applicable and is relatively straightforward to understand and administer. It\u2019s especially intuitive for manufacturers dealing with inventory that physically rotates in roughly the same order as it arrives, including materials with limited shelf lives or products where older stock should generally be consumed before newer batches.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It can also work well for manufacturers with stable, predictable purchasing patterns, standardized products, and relatively simple inventory records. For smaller businesses, FIFO is often a practical choice because it\u2019s easy to explain, implement, and reconcile without extensive lot-level cost tracking.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">FIFO is permitted under both US GAAP (Generally Accepted Accounting Principles) and IFRS (International Financial Reporting Standards) Accounting Standards.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Watch out for<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The purchase price of older stock is often lower than for newer stock as material prices rise. If this is the case, FIFO generally produces lower COGS and higher reported gross profit margins than LIFO under the same conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That doesn\u2019t mean FIFO is inaccurate, but managers should understand that the margins shown in their accounts may be based in part on older input costs rather than today&#8217;s replacement costs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">LIFO<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Last-In, First-Out (LIFO)<\/strong> assumes that the newest inventory costs are assigned to goods sold or consumed first. It\u2019s the same logic as FIFO, but in reverse. Older inventory costs consequently remain in ending inventory.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">LIFO example<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Using our example, the youngest 150 units consist of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>100 units \u00d7 $15 = $1,500;<\/li>\n\n\n\n<li>50 units \u00d7 $12 = $600.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">COGS becomes <strong>$2,100<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ending inventory consists of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>100 units \u00d7 $10 = $1,000;<\/li>\n\n\n\n<li>50 units \u00d7 $12 = $600.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Ending inventory value is <strong>$1,600<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">When it makes sense<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">LIFO can be attractive when input prices are rising because current, higher costs are recognized in COGS sooner. This makes reported margins more closely reflect the costs assigned to sold products as the prices are closer to what the business actually paid for materials and components.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During inflation periods, LIGO can also reduce reported taxable income and lower your overall tax liability because higher recent costs increase COGS. However, the tax effect depends on the company&#8217;s jurisdiction and accounting setup, so you shouldn\u2019t treat it as the main reason to choose LIFO.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">LIFO remains an accepted method under US GAAP and can also be elected for US tax purposes. It\u2019s most relevant for US-based manufacturers with relatively stable, interchangeable inventory and a clear reason to align reported costs more closely with current purchasing costs.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Watch out for<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">LIFO is prohibited under the IFRS. If you\u2019re thinking of operating across multiple jurisdictions, you might face additional reporting complexity if LIFO is used for one entity but not another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">LIFO can also leave old inventory costs on the balance sheet for a long time. If inventory later falls below those older layers, a <strong>LIFO liquidation<\/strong> may occur. This causes older, lower costs to move into COGS, which can temporarily increase reported profit and make margins less reflective of current costs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For SMEs, LIFO is therefore a method that should generally be selected together with your accountant rather than simply because it produces a desirable result in a particular year. Consider the reporting framework, tax position, inventory turnover, and ability to maintain the required records before you decide to adopt it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.mrpeasy.com\/blog\/fifo-vs-lifo\/\" target=\"_blank\" rel=\"noreferrer noopener\"><em>Check out our VS. article on FIFO &amp; LIFO.<\/em><\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Weighted average cost<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.mrpeasy.com\/blog\/weighted-average-cost-wa\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>weighted average cost<\/strong><\/a><strong> <\/strong>method <strong>(WAC) <\/strong>pools together the costs of all similar inventory and calculates an average cost per unit. So, instead of tracking whether the $10, $12, or $15 component was consumed in a job or sold, each component with the same <a href=\"https:\/\/www.mrpeasy.com\/blog\/stock-keeping-unit-sku-best-practices-for-inventory-classification\/\" target=\"_blank\" rel=\"noreferrer noopener\">SKU (stock keeping unit)<\/a> receives the same average cost. The costs of new and old stock are blended together rather than maintained as separate FIFO or LIFO cost layers.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Weighted average cost example<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Our 300 components cost a total of $3,700.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Average unit cost is therefore:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>$3,700 \u00f7 300 = $12.33<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For 150 units:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>COGS = 150 \u00d7 $12.33 = approximately $1,850<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The remaining 150 units are also valued at approximately <strong>$1,850<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a perpetual inventory system, the average cost is usually recalculated whenever new inventory is received. This is often referred to as a moving weighted average.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">When it makes sense<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Weighted average costing (WAC) works well when businesses handle large quantities of interchangeable items, where identifying the cost of every individual unit would make little sense. Examples include fasteners, bulk raw materials, chemicals, packaging materials, standard electronic components, and other stock that\u2019s purchased repeatedly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For manufacturers with frequent purchases at slightly different prices, WAC simplifies administering inventory costing. This can be especially useful for SMEs with high transaction volumes and standardized products, where simplicity and consistency outweigh knowing whether one particular component came from a $10 or $12 purchase batch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The WAC method also smooths short-term fluctuations in purchase prices, making product costs and margins less volatile from one transaction to the next. WAC is permitted under both US GAAP and IFRS.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Watch out for<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The smoothing effect can also be a disadvantage in some situations. If material prices rise or fall sharply, the average inventory cost can respond more slowly than current supplier prices. Managers looking only at accounting costs may therefore underestimate the cost of replenishing inventory or producing the next batch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">WAC can also hide meaningful cost differences between lots. If one batch was purchased at an unusually high price because of expedited freight, tariffs, shortages, or other exceptional costs, averaging hides that difference across the inventory pool, instead of keeping it visible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this reason, weighted average costing is usually better suited to genuinely interchangeable stock. It\u2019s less useful when individual batches have wildly different costs, or when the business needs lot-level profitability and traceability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Specific identification<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.mrpeasy.com\/blog\/specific-identification\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>specific identification<\/strong><\/a> (SI) simply assigns the actual cost of a particular inventory item to that specific item. No averaging or cost assumption is involved. The business tracks the cost associated with the exact unit, batch, lot, or project that\u2019s ultimately sold or consumed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specific identification is the most direct of the four methods: the cost recognized in COGS is the actual recorded cost of the inventory that left the business.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Specific identification example<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Suppose a manufacturer builds three custom industrial assemblies, costing:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Assembly A: $2,000;<\/li>\n\n\n\n<li>Assembly B: $2,300;<\/li>\n\n\n\n<li>Assembly C: $2,700.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If Assembly B is sold, the company records <strong>$2,300 as COGS<\/strong>. The remaining inventory value is $4,700.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There\u2019s no FIFO or average assumption involved because the exact inventory item is identifiable. In manufacturing, the same principle can be applied at the lot or serial-number level. With sufficient stock traceability, a manufacturer knows that a particular finished machine contains components from specific purchase lots and has accumulated a known amount of labor and allocated production overhead.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">When it makes sense<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Specific identification is particularly suitable for unique, high-value, customized, serialized, or otherwise individually traceable inventory. Typical examples include custom machinery, <a href=\"https:\/\/www.mrpeasy.com\/blog\/engineer-to-order-process-flow-and-best-practices\/\" target=\"_blank\" rel=\"noreferrer noopener\">engineered-to-order<\/a> products, specialist equipment, and expensive serialized parts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SI can also make sense when production costs vary significantly from one job or unit to another. A manufacturer producing ten custom machines may gain far more useful information by knowing the actual cost of each machine than by averaging their costs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For make-to-order and engineer-to-order manufacturers, this can improve job costing and margin analysis because revenue from an individual customer order can be compared against the specific costs incurred to fulfill it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specific identification is allowed under both US GAAP and IFRS. It\u2019s actually required under IFRS\u2019s IAS 2 accounting rule for inventory items that are not ordinarily interchangeable.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Watch out for<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The main drawback of this method is the level of recordkeeping required. It presumes the capability to reliably link physical items, lots, or serial numbers to their costs throughout purchasing, storage, production, and sale. This may include not only purchase prices but also landed costs, material consumption, labor, subcontracting, and production overhead.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specific identification becomes difficult if materials are routinely mixed together, inventory movements are not recorded consistently, or production staff fail to properly maintain lot and serial traceability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s not practical for large quantities of low-value, interchangeable items as tracking their exact costs is unlikely to provide enough additional insight to justify the administrative effort. For this reason, SI tends to work best where the economic value of detailed traceability is high enough to support the extra data requirements.<\/p>\n\n\n<div class=\"banner-v1\">\n    <div class=\"banner__text\">\n        <div class=\"banner-v1__title\">Always know what you have in stock and what it&#8217;s worth<\/div>\n        <div class=\"banner-v1__desc\">MRPeasy integrates sales, purchases, production, inventory, and finances to provide you with an accurate real-time overview of your business.<\/div>\n        <div><a class=\"banner-v1__link\" href=\"https:\/\/www.mrpeasy.com\/sign-up\/\" target=\"_blank\" data-ga-event=\"blog_signup_banner_white\">Try for free<\/a><\/div>\n    <\/div>\n    <div class=\"banner__img\">\n        <img decoding=\"async\" src=\"https:\/\/www.mrpeasy.com\/blog\/wp-content\/themes\/mrpeasy\/assets\/images\/banner.svg\" alt=\"banner\">\n    <\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"FIFO_vs_LIFO_vs_WAC_vs_SI_compared\"><\/span>FIFO vs. LIFO vs. WAC vs. SI compared<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The right method to use depends mostly on what type of inventory you\u2019re managing, and less on which calculation looks best on paper.<\/p>\n\n\n\n<div style=\"margin: 28px 0;

A practical choice reflects your business type, <a href=\"https:\/\/www.mrpeasy.com\/inventory-management\/\" target=\"_blank\" rel=\"noreferrer noopener\">inventory&nbsp;management<\/a>&nbsp;requirements, and accounting needs. Here are six starting points to help you make an informed decision.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Accounting requirements and regulations in your markets<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Your starting point is knowing which methods you\u2019re actually allowed to use in your jurisdiction. Inventory valuation rules differ depending on the accounting framework and tax jurisdictions where you operate. Businesses reporting under <a href=\"https:\/\/www.investopedia.com\/ask\/answers\/011315\/what-difference-between-gaap-and-ifrs.asp\" target=\"_blank\" rel=\"noreferrer noopener\">IFRS and US GAAP<\/a> face different constraints \u2013&nbsp;IFRS&nbsp;does not permit LIFO, while US GAAP permits FIFO, LIFO, weighted average, and specific identification.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">More specific tax<a href=\"https:\/\/www.investopedia.com\/ask\/answers\/011315\/what-difference-between-gaap-and-ifrs.asp\"> <\/a>rules can introduce further requirements, so your final accounting method should always be confirmed with an accountant familiar with the jurisdictions where you\u2019re operating.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Consider how your inventory behaves<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Are your inventory items interchangeable? If one unit is essentially identical to another, FIFO, LIFO, or weighted-average usually makes more sense than tracking each item&#8217;s exact cost. But if products need to be individually distinguishable, customized, serialized, or have materially different costs, specific identification becomes much more useful.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Physical inventory characteristics also play a role in this decision to some degree. Even though physical stock rotation and accounting cost flow are technically separate issues, perishable or age-sensitive materials tend to align better with&nbsp;FIFO.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Consider cost trends and financial goals<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Think about whether your purchasing costs are volatile and how much it affects your finances and cash flow. During sustained inflation, FIFO, LIFO, and WAC can all produce noticeably different COGS and inventory values. That affects reported gross margin, profit, and potentially taxes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Management should understand these effects, but a word of caution \u2013 valuation methods shouldn\u2019t be switched back and forth simply to produce a preferred financial result year on year. Consistency and your accounting requirements matter more.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Consider your traceability constraints<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For perfect tracking, specific identification may seem like the natural choice because it uses the actual cost of each individual item. But that precision is useful only if your business can reliably maintain the necessary records and has a meaningful financial reason to do so. If materials move through multiple production stages without consistent lot, batch, or serial tracking, identifying their exact costs can quickly become impractical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">More importantly, don\u2019t introduce extensive traceability simply to justify a high-maintenance costing method. The additional tracking effort should be supported by staff willingness to go the extra mile, and a clear business need like high-value inventory, customer-specific costing, or regulatory requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Check out our essential guide on <\/em><a href=\"https:\/\/www.mrpeasy.com\/blog\/inventory-tracking\/\" target=\"_blank\" rel=\"noreferrer noopener\"><em>inventory tracking<\/em><\/a><em>.<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Consider your production model<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Your production type also affects what level of costing detail is useful. A high-volume <a href=\"https:\/\/www.mrpeasy.com\/blog\/make-to-stock-mts-manufacturing-process-flow-and-best-practices\/\" target=\"_blank\" rel=\"noreferrer noopener\">make-to-stock<\/a> manufacturer that produces thousands of identical units has different requirements from an engineer-to-order company that builds 10 customized machines over the course of a quarter.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Batch manufacturers may benefit from tracking costs by lot, while custom manufacturers often need to know what each individual job or product actually cost to make. So your chosen inventory valuation approach should make sense in line with how production is planned and reported.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Consider your systems and administrative effort<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, ask how difficult the method will be to maintain in practice. A super-precise costing system creates more problems than it provides value if employees fail to keep the underlying data current, and tracking consistency starts slipping.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Plan how your accounting, inventory, and <a href=\"https:\/\/www.mrpeasy.com\/manufacturing-software\/\" target=\"_blank\" rel=\"noreferrer noopener\">manufacturing system<\/a> can support the chosen approach, how much and what kind of work is required to maintain them, and whether the process will remain manageable, should your transaction volumes increase or new staff join the team.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For SMEs in particular, a slightly simpler method that can be followed consistently is usually far more useful than a highly detailed system that constantly requires manual intervention.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_accurate_inventory_valuation_matters\"><\/span>Why accurate inventory valuation matters<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Inventory valuation is not just something for the accountant \u2013 it affects everyday management decisions more than you think. If your inventory costs are wrong, your margins are off \u2013 you might think that a product is profitable when, in truth, material costs eat into the margin or tie up more cash in inventory than you realize.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For manufacturers, value is constantly moving through the business: from purchased materials to WIP, from WIP to finished goods, and eventually into COGS. The better you track that movement, the clearer picture you get of what the business is actually earning and where money gets tied up.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Financial benefits<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The first place where inaccurate valuation shows up is the financial statements. If ending inventory is valued too high, COGS is understated, and profit looks better than it really is. If inventory is valued too low, the opposite happens. This same glitch affects gross margin, taxes, and the value of inventory on your <a href=\"https:\/\/en.wikipedia.org\/wiki\/Balance_sheet\" target=\"_blank\" rel=\"noreferrer noopener\">balance sheet<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical question is, <strong>can I trust the margins I\u2019m looking at? <\/strong>Suppose a material used in one of your products used to cost $10 per unit but now costs $12, a 20% increase. If the COGS you are seeing still reflects mostly older $10 inventory, the product&#8217;s reported margin may look healthier than the margin you would actually make when replenishing materials at today&#8217;s $12 price.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding your valuation gives you a firmer basis for decision-making. Things like whether selling prices still cover manufacturing costs, which products or jobs are genuinely profitable, whether margins are improving or deteriorating, or how much of your working capital is tied up in inventory. And of course, it also makes your financial reporting more reliable for accountants, regulators, or investors.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Operational benefits<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The bigger daily benefit is that good inventory valuation turns your costing data into management information. If you know what materials cost, how much value is held up in WIP, or what your finished goods are really worth, you can ask better questions.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Material costs rising faster than your selling prices? <\/strong>Renegotiate supplier terms or adjust the selling prices.<\/li>\n\n\n\n<li><strong>Too much money is sitting in stock?<\/strong> Excess inventory means working capital that cannot be used elsewhere. Work to increase your <a href=\"https:\/\/www.mrpeasy.com\/blog\/inventory-turnover-ratio\/\" target=\"_blank\" rel=\"noreferrer noopener\">inventory turnover ratio<\/a>.<\/li>\n\n\n\n<li><strong>Some products less profitable than you thought?<\/strong> Better cost data can expose products with healthy revenue but weak margins.<\/li>\n\n\n\n<li><strong>WIP building up somewhere in production?<\/strong> Rising WIP value can point to production bottlenecks, stretched supplier <a href=\"https:\/\/www.mrpeasy.com\/blog\/lead-time\/\">lead times<\/a>, or other constraints that make jobs take longer than expected.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The takeaway is simple \u2013 better inventory valuation gives you better cost information, which ultimately protects your financial health and leads to better decisions.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Tools_for_automating_inventory_valuation\"><\/span>Tools for automating inventory valuation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Inventory valuation can be calculated manually, and small companies with periodic inventory systems have been doing it like that for decades. But the process becomes increasingly difficult as the number of products, purchases, and production transactions grows. So the best choice really depends on the complexity of your operation, most of all.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Spreadsheets<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Spreadsheets are often the starting point for small businesses. For a company with just a handful of products, few suppliers, regular purchases, and simple inventory flows, a spreadsheet can be perfectly adequate to calculate FIFO layers, weighted averages, COGS, and ending inventory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The problem is scalability and what happens when more than one person needs to handle it all. As transaction volumes increase, spreadsheets require linearly more manual data entry and reconciliation. Tracking WIP, purchase-cost layers, production consumption, returns, write-offs, and multiple locations will result in large interconnected files that only one or two people fully understand. Without automation, they\u2019ll be stuck as the irreplaceable cog in all your processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even if spreadsheet calculations are correct, keeping purchases, inventory values, COGS, and accounting records synchronized becomes increasingly difficult. This is often the point where many businesses move at least the financial side of inventory valuation into accounting software.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Accounting software<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Accounting software like <a href=\"https:\/\/www.mrpeasy.com\/xero\/\" target=\"_blank\" rel=\"noreferrer noopener\">Xero<\/a> or <a href=\"https:\/\/www.mrpeasy.com\/quickbooks\/\" target=\"_blank\" rel=\"noreferrer noopener\">QuickBooks<\/a> automates much of the financial side of inventory valuation. It can record purchases, maintain inventory asset and COGS accounts, and produce financial statements without requiring every calculation to be rebuilt manually in some disconnected spreadsheet. Some systems also include basic inventory functionality and can calculate inventory values using methods such as FIFO or weighted average.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For very small distributors or simple product businesses, that may actually be enough. But manufacturing introduces another layer of complexity \u2013 materials are consumed into production, value accumulates in the WIP account, labor and overhead may need to be added, and several components can become one finished product.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most general-purpose accounting software is designed primarily to record the financial results of these activities rather than manage the production processes behind them. So again, as complexity grows, businesses should add dedicated inventory software to the stack or integrate their accounting system with a manufacturing ERP.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Inventory management software<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Inventory management software adds many layers that general-purpose accounting systems lack. Its main selling point is the move to a perpetual inventory system. This tracks what inventory you have, where it is, and how it moves through the business automatically.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the system, it can further record receipts and issues, track batches and serial numbers, manage multiple locations, and perform stock adjustments. Costing information and account sync are then passed to the accounting system automatically instead of being maintained separately.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For distributors and straightforward inventory businesses, that may be enough. But for manufacturers and really anyone who adds any sort of value to their purchases, inventory doesn\u2019t merely arrive and leave. Raw materials and components are transformed into other items, even if only repackaging or <a href=\"https:\/\/www.mrpeasy.com\/blog\/kitting\/\" target=\"_blank\" rel=\"noreferrer noopener\">kitting<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Manufacturing ERP systems<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Once you start transforming inventory, just knowing what came in and what went out is no longer enough. You now need to know <strong>what went into each production run, when those runs will finish, how much value was added along the way, and what the finished product actually costs you to make<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.mrpeasy.com\/blog\/inventory-software-not-enough-for-manufacturers\/\" target=\"_blank\" rel=\"noreferrer noopener\">This is where manufacturing software outperforms inventory management software.<\/a> Materials issued to a production order carry their costs into WIP. Labor, subcontracting, and manufacturing overheads are added as production progresses, and when the job is finished, the accumulated costs are recorded using actual production data. Once the products are sold, it can then flow into COGS automatically.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For manufacturers, the main benefit is that you no longer have to reconstruct this chain at the end of the month. Your inventory valuation is built from the same transactions your team already records to purchase materials, run production, receive finished goods, and ship orders. That gives you a much more useful view of the business. Not only live inventory values, but also how much it\u2019s worth at different stages, what individual products or jobs actually cost, and whether the margins still make sense as material and production costs change.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"526\" src=\"https:\/\/www.mrpeasy.com\/blog\/wp-content\/uploads\/2022\/04\/Stock-movement-1024x526.png\" alt=\"Stock movement\" class=\"wp-image-20206\" srcset=\"https:\/\/www.mrpeasy.com\/blog\/wp-content\/uploads\/2022\/04\/Stock-movement-1024x526.png 1024w, https:\/\/www.mrpeasy.com\/blog\/wp-content\/uploads\/2022\/04\/Stock-movement-300x154.png 300w, https:\/\/www.mrpeasy.com\/blog\/wp-content\/uploads\/2022\/04\/Stock-movement-768x395.png 768w, https:\/\/www.mrpeasy.com\/blog\/wp-content\/uploads\/2022\/04\/Stock-movement-1536x790.png 1536w, https:\/\/www.mrpeasy.com\/blog\/wp-content\/uploads\/2022\/04\/Stock-movement-2048x1053.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><strong>In MRPeasy, stock movements are compiled automatically for an easy way to view beginning and ending inventory.<\/strong><\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_MRPeasy_simplifies_inventory_valuation\"><\/span>How MRPeasy simplifies inventory valuation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/mrpeasy.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">MRPeasy<\/a> combines inventory, purchasing, production, and costing into one system, so inventory values are updated from the very transactions that create the costs.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Track actual costs by stock lot.<\/strong> Purchased items retain the cost of their specific stock lot, including applicable additional purchase costs. This means you can follow actual costs instead of assigning a static standard cost to everything in stock.<\/li>\n\n\n\n<li><strong>Get manufacturing costs as you produce.<\/strong> For manufactured products, MRPeasy calculates actual cost from the materials consumed plus labor and manufacturing overhead recorded against the Manufacturing Order. That gives you a cost trail from purchased components through to the finished product.<\/li>\n\n\n\n<li><strong>Keep stock movements and costs connected.<\/strong> Receipts, material consumption, completed production, shipments, write-offs, locations, lots, and serial numbers are handled in the same inventory system. You can understand not just how many items you have, but where their recorded value came from.<\/li>\n\n\n\n<li><strong>Use FIFO automatically for stock allocation.<\/strong> MRPeasy books available stock using FIFO by default, or <a href=\"https:\/\/www.mrpeasy.com\/blog\/fefo\/\">FEFO<\/a> for perishable goods, while retaining the actual cost of the stock lots involved.<\/li>\n\n\n\n<li><strong>See actual product costs and margins.<\/strong> Once products are produced and shipped, you can compare their selling price with actual COGS, including separate material, labor, and manufacturing overhead components for manufactured items.<\/li>\n\n\n\n<li><strong>Keep accounting in sync.<\/strong> MRPeasy integrates with Xero and QuickBooks Online, including optional synchronization of inventory, WIP, COGS, direct labor, and manufacturing overhead transactions. This reduces the need to manually recreate manufacturing accounting entries in your bookkeeping system.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Frequently_asked_questions_FAQ\"><\/span>Frequently asked questions (FAQ)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1789413682796\"><strong class=\"schema-faq-question\">What are the four methods of inventory valuation?<\/strong> <p class=\"schema-faq-answer\">The four main inventory valuation methods are <strong>FIFO, LIFO, weighted average cost (WAC), and specific identification (SI)<\/strong>. FIFO assigns the oldest costs first, LIFO uses the newest costs first, WAC averages similar inventory costs, and SI tracks the actual cost of specific items or lots. The best fit depends on how interchangeable your inventory is, how your costs behave, and which accounting rules apply to your business.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1789414444468\"><strong class=\"schema-faq-question\">How does LIFO impact taxes?<\/strong> <p class=\"schema-faq-answer\">When costs are rising, <strong>LIFO usually produces higher COGS and lower reported profit<\/strong>, which can reduce taxable income. However, LIFO is permitted under US GAAP but prohibited under IFRS, and the exact tax impact depends on your jurisdiction and accounting setup. Treat it as an accounting and tax decision, not as a way to lower taxes in a given year.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1789414478506\"><strong class=\"schema-faq-question\">When is the Weighted Average Cost Method useful?<\/strong> <p class=\"schema-faq-answer\">The <strong>weighted average cost method is useful when you handle large quantities of interchangeable inventory purchased at varying prices<\/strong>. It simplifies costing by assigning the same average cost to similar units and helps smooth short-term price fluctuations. WAC is especially practical for items such as bulk materials, fasteners, packaging, chemicals, and other standardized components.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1789414558282\"><strong class=\"schema-faq-question\">How do different inventory valuation methods affect financial statements?<\/strong> <p class=\"schema-faq-answer\">Different inventory valuation methods change how costs are split between <strong>COGS and ending inventory<\/strong>. When prices are changing, this can affect reported gross profit, net income, inventory assets, and potentially taxes, even when the same quantities are purchased and sold. This is why you should understand not just the method being used, but also how it influences your margins and inventory values in reports.<\/p> <\/div> <\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><em>You might also like: <a href=\"https:\/\/www.mrpeasy.com\/blog\/improve-inventory-management-efficiency\/\">12 Tips for Improving Inventory Management Efficiency<\/a><\/em>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Inventory is an asset, but knowing its worth is not always as simple as multiplying the number of units in stock by their purchase price.

FIFO assigns the oldest costs first, LIFO uses the newest costs first, WAC averages similar inventory costs, and SI tracks the actual cost of specific items or lots. The best fit depends on how interchangeable your inventory is, how your costs behave, and which accounting rules apply to your business.","inLanguage":"en-US"},"inLanguage":"en-US"},{"@type":"Question","@id":"https:\/\/www.mrpeasy.com\/blog\/inventory-valuation-methods\/#faq-question-1789414444468","position":2,"url":"https:\/\/www.mrpeasy.com\/blog\/inventory-valuation-methods\/#faq-question-1789414444468","name":"How does LIFO impact taxes?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"When costs are rising, <strong>LIFO usually produces higher COGS and lower reported profit<\/strong>, which can reduce taxable income. However, LIFO is permitted under US GAAP but prohibited under IFRS, and the exact tax impact depends on your jurisdiction and accounting setup.

When prices are changing, this can affect reported gross profit, net income, inventory assets, and potentially taxes, even when the same quantities are purchased and sold.
