Net realizable value, or NRV, is the estimated selling price of an asset minus any costs still needed to complete it and sell it. Accountants use it so that inventory and accounts receivable appear on the balance sheet at the cash a company can realistically expect to collect, not an outdated purchase price or an optimistic invoice total.
The Formula
NRV has three moving parts:
- Estimated selling price in the normal course of business.
- Costs to complete, such as finishing or packaging the product.
- Costs to sell, including shipping, sales commissions, brokerage fees, and delivery.
Subtract the completion and selling costs from the expected selling price, and the remainder is NRV.
A short example: a company expects to sell a piece of equipment for $5,000. Shipping runs $200 and the sales commission is $300. NRV is $5,000 − $200 − $300 = $4,500. The financial statements carry $4,500, not the $5,000 sticker price.
NRV Is Not Fair Value
Fair value (sometimes called fair market value) is what a willing, informed buyer would pay on the open market, with no deduction for transaction costs. NRV starts from that same market price and then subtracts the seller’s costs of closing the deal. Because of those deductions, NRV is almost always lower than fair value. An asset reported at NRV already accounts for the expense of selling it; an asset reported at fair value does not.
Lower of Cost or Net Realizable Value for Inventory
The most common use of NRV is an inventory rule called “lower of cost or net realizable value,” or LCNRV. A company compares what it originally paid for its inventory to the inventory’s current NRV. If NRV has fallen below cost, the company writes the inventory down to the lower figure. If NRV is still above cost, the original cost stays on the books. The point is to keep inventory from sitting on the balance sheet at a value higher than the cash it can actually generate.
FASB adopted this rule through Accounting Standards Update 2015-11, which simplified the older “lower of cost or market” method for most companies. LCNRV applies to inventory measured using FIFO, average cost, or a similar method. Companies that use LIFO or the retail inventory method still follow the older lower-of-cost-or-market approach, which compares cost to current replacement cost (with a ceiling of NRV and a floor of NRV minus a normal profit margin) rather than directly to NRV.1Financial Accounting Standards Board. ASU 2015-11
What Triggers a Write-Down
Several situations push NRV below original cost:
- Physical damage that reduces resale value.
- Obsolescence from technological change or shifting consumer preferences.
- Price competition that forces a company to sell below its own cost.
- Excess supply or slow-moving stock that requires markdowns.
Recognizing the loss when the decline occurs, rather than waiting for the eventual sale, gives investors and creditors a more accurate picture of what the inventory is worth today.
Recording the Write-Down
The loss goes on the income statement. A typical journal entry debits a loss account, such as “Loss on Inventory Write-Down,” and credits either inventory directly or a contra-asset account called “Allowance for Inventory Losses.” If the amount is immaterial, the company folds it into cost of goods sold instead of showing it separately.
Under U.S. GAAP, once inventory is written down, the write-down cannot be reversed even if the market later recovers. The reduced figure becomes the new cost basis.
NRV for Accounts Receivable
NRV also applies to money customers owe. The NRV of accounts receivable is gross receivables minus the allowance for doubtful accounts, a contra-asset that represents invoices the company does not expect to collect.
Say a business has $1,000,000 in outstanding invoices and its history shows a 2% default rate. It records a $20,000 allowance, and the balance sheet shows receivables of $980,000. Management updates the estimate regularly using payment history, customer creditworthiness, and current economic conditions.
Valuing receivables at NRV matters for liquidity measures like the current ratio (current assets ÷ current liabilities) and the quick ratio. Skipping the doubtful-accounts adjustment overstates those ratios and can mislead lenders and investors about a company’s ability to meet short-term obligations.
GAAP vs. IFRS
Both U.S. GAAP and International Financial Reporting Standards require inventory to be measured at the lower of cost and NRV, but the details diverge.
- Scope. Under IFRS (IAS 2), LCNRV applies to all inventory regardless of costing method. Under U.S. GAAP, it applies only to FIFO, average cost, and similar methods; LIFO and retail-method inventory follow the older lower-of-cost-or-market approach.1Financial Accounting Standards Board. ASU 2015-11
- Reversals. IFRS allows a previous write-down to be reversed if NRV recovers, though not above the original cost. U.S. GAAP prohibits reversals entirely.
- LIFO. IFRS does not permit LIFO at all, so the LIFO carve-out in U.S. GAAP has no IFRS counterpart.
A company that reports under both frameworks, such as a U.S. subsidiary of a foreign parent, can end up with two different inventory values for the same goods.
Agricultural and Commodity Exception
Some industries are permitted to report inventory at NRV directly, without first comparing it to historical cost. Under U.S. GAAP (ASC Topic 905), agricultural producers can use NRV when three conditions are met: reliable and readily determinable market prices exist, the producer cannot influence those prices, and disposal costs are minimal. Grain, livestock available for immediate sale, and precious metals commonly qualify. The products are interchangeable, prices are transparent, and disposal is cheap, so tracking historical cost for each unit adds complexity without improving accuracy.
Tax Treatment Is Separate
A financial-statement write-down to NRV does not automatically produce a tax deduction. The IRS has its own inventory rules, primarily under Treasury Regulation § 1.471-4, which governs the lower-of-cost-or-market method for tax purposes.2eCFR. 26 CFR 1.471-4 – Inventories at Cost or Market, Whichever Is Lower
For damaged, obsolete, or otherwise impaired inventory, called “subnormal goods,” the IRS permits valuation at actual selling price minus direct disposal costs, which is effectively NRV. The taxpayer has to meet strict conditions:3IRS.gov. Lower of Cost or Market (LCM)
- Subnormal finished goods must actually be offered for sale at the reduced price within 30 days after the inventory date.
- Records must show how the goods were disposed of.
- The taxpayer bears the burden of proving the goods are subnormal through an actual sale, an offering for sale, or a contract cancellation.
- Items that cannot be sold at any price because of physical deterioration or obsolescence must be removed from inventory entirely.
Because book and tax rules differ, a company may need to track two inventory values, one for financial statements and one for the return. A tax advisor can confirm whether a particular book write-down qualifies for a tax deduction under the current IRS rules.
How Auditors Test NRV
Because NRV depends on management’s estimates of future prices and costs, auditors approach it with professional skepticism. Under auditing standards, they evaluate whether all material estimates have been identified, whether each is reasonable given the circumstances, and whether the estimates are properly disclosed.4PCAOB. AU Section 342 – Auditing Accounting Estimates
Auditors focus on assumptions most sensitive to change, those that depart from historical patterns, and those subjective enough to invite bias. They review how management built the estimate, compare it against the company’s past accuracy, and sometimes develop an independent estimate for comparison.
Not every dip in NRV forces a write-down. Accountants apply a materiality threshold, asking whether the adjustment is large enough to matter to a reasonable investor. A 5% benchmark against a relevant line item is a common starting point, but the SEC has said that a numerical cutoff alone is not enough. Qualitative factors, such as an adjustment that turns a profit into a loss, masks a declining earnings trend, affects loan covenant compliance, or increases management’s bonus, can make even a small write-down material.5U.S. Securities & Exchange Commission. Staff Accounting Bulletin No. 99 – Materiality
Companies disclose their inventory accounting method, such as “lower of cost or net realizable value,” in the footnotes to their financial statements, and inventory markdowns are reported as a component of cost of goods sold.
