Inventory Valuation Methods in India: FIFO, Weighted Average & NRV Explained (AS 2 / Ind AS 2)

Inventory Valuation Methods in India: FIFO, Weighted Average & NRV Explained (AS 2 / Ind AS 2)

If you run a trading, manufacturing, or retail business in India, a big chunk of your money is probably sitting quietly on your shelves, in your godown, or on your factory floor, as inventory. Here's the thing most founders don't realise until their CA points it out during audit season: how you value that inventory can change your reported profit, your tax outgo, and even whether a bank approves your loan.

Inventory valuation sounds like a dry accounting topic, but it quietly shapes your entire financial story. Get it wrong, and your books either overstate profits (inviting tax trouble) or understate them (scaring away investors and lenders). Get it right, and you build a clean, credible, bank-ready set of financial statements. In this article, we break down FIFO, Weighted Average, and the Lower of Cost or Net Realisable Value rule, in plain English.

What is Inventory Valuation

Inventory valuation is the process of assigning a rupee value to the goods your business is holding at any point in time, whether raw materials, work-in-progress, or finished goods waiting to be sold. This sounds simple, but it rarely is, because businesses buy the same item at different prices at different times. A trader might buy the same SKU at Rs 100 in April, Rs 110 in June, and Rs 105 in September. When some units are sold and some remain unsold at year-end, what value do you assign to the unsold ones? That is exactly what inventory valuation methods are designed to answer.

This matters because inventory sits at the intersection of your Profit & Loss account and your Balance Sheet. The value of your closing stock directly reduces your Cost of Goods Sold (COGS): the higher your closing stock value, the lower your COGS, and the higher your reported profit (and vice versa). That same closing stock figure also appears as a current asset on your Balance Sheet, affecting your working capital and how healthy your business looks to a bank or investor. One number quietly shapes two of your most important financial statements.

Because this number carries so much weight, it cannot be left to guesswork. In India, inventory valuation is governed by Accounting Standard 2 (AS 2), "Valuation of Inventories," issued by ICAI and applicable to companies not required to follow Ind AS. Larger companies, listed entities, and those crossing specified net worth or turnover thresholds instead follow Ind AS 2, "Inventories." Both standards are conceptually similar and lay down the permitted costing methods, what costs can be included, and the rule that inventory must never be shown above what it can realistically fetch in the market.

Why It Matters

Inventory valuation feels like a back-office technicality, but its effects ripple through almost every part of the business.

First, accurate profit measurement. Your net profit depends heavily on how closing stock is valued. Overvalue it, and profit looks inflated on paper, meaning you may pay more tax than necessary. Undervalue it, and you understate profits, raising red flags with tax authorities.

Second, tax implications. The valuation method used for tax purposes must be consistent and defensible. Arbitrary swings from year to year attract scrutiny from tax officers, since they can be used to shift profit between years.

Third, lender and investor confidence. Banks look closely at inventory levels and valuation methods during due diligence, since inventory is often pledged as collateral for cash credit limits. Investors want to know if the stock is genuinely worth what the balance sheet says. A business that can explain its valuation method with proper stock records earns trust faster.

Fourth, GST and audit relevance. Stock records feed into input tax credit reconciliation and physical stock verification during assessments. Statutory auditors specifically test inventory valuation, since it involves management judgement around method and NRV estimates. A documented, standards-based policy makes this far smoother.

Key Concepts You Need to Know

FIFO (First-In-First-Out): This assumes goods purchased first are sold first, so unsold stock at period-end is assumed to consist of the most recently purchased goods. This mirrors how many businesses manage physical stock, especially perishables or fashion goods. FIFO tends to value closing stock closer to current market prices, especially useful during rising prices.

Weighted Average Cost method: Instead of tracking specific batches, this calculates one average cost per unit by dividing total cost of goods available (opening stock plus all purchases) by total units available. Every unit sold and remaining is valued at this average. It smooths out price fluctuations and suits bulk or fungible goods like commodities and chemicals.

LIFO (Last-In-First-Out) is NOT permitted. This is a point many founders get wrong, especially if they've studied international textbooks. LIFO assumes the most recently purchased goods are sold first, leaving older, lower-priced stock in closing inventory. While allowed under US GAAP, LIFO is explicitly not permitted under Indian Accounting Standards, neither AS 2 nor Ind AS 2. If your accounting software defaults to LIFO internally, that figure cannot be used for statutory books, tax filings, or audited financial statements in India. Only FIFO and Weighted Average are acceptable.

Lower of Cost or Net Realisable Value (NRV): This is the rule that sits above whichever costing method you choose. Once you calculate cost using FIFO or Weighted Average, you must also determine the Net Realisable Value, and record whichever is lower. NRV is the estimated selling price in the ordinary course of business, less estimated costs of completion and less estimated costs necessary to make the sale (commission, freight, packing). In simple terms: what will you actually get for this stock after finishing and selling it? If that is lower than cost, you must write the inventory down. This prevents businesses from carrying stock at inflated values when the market has moved against them, think unsold winter jackets in March or outdated electronics.

How to Value Inventory — Step by Step

1. Identify the cost components. Include purchase price, import duties, freight inwards, and directly attributable costs of bringing inventory to its present location and condition, plus a share of production overheads for manufactured goods. Exclude abnormal wastage, unrelated storage, administrative overheads, and selling costs.

1. Choose a costing method consistently. Decide whether FIFO or Weighted Average best represents your goods, and apply it consistently across periods. LIFO is off the table under Indian standards.

1. Calculate cost under the chosen method. Use stock records, purchase invoices, quantities, and dates to compute closing stock cost for each item or category.

1. Determine the Net Realisable Value (NRV). Estimate the realistic selling price for each item, then deduct remaining completion costs and selling costs like commission or transport.

1. Compare cost and NRV, and record the lower value. Do this item by item or category by category, since averaging gains against losses can hide real write-downs.

1. Maintain consistency period to period. Stick with your chosen method unless there is a genuine, justifiable reason to change. Frequent, unexplained switching is a red flag for auditors and tax authorities.

1. Disclose the method used in financial statements. Both standards require disclosure of the accounting policy and cost formula used, giving lenders, investors, and auditors confidence in your numbers.

A Worked Example (Illustrative Only)

Let's walk through a simple, hypothetical example. All figures below are illustrative only, made up purely to demonstrate the calculation.

Imagine "Sample Traders," dealing in a single product line during the month:

• Opening stock: 100 units at Rs 50 per unit
• Purchase 1: 200 units at Rs 55 per unit
• Purchase 2: 150 units at Rs 60 per unit
• Total units sold: 350 units
• Closing stock: 100 units

Under FIFO: The 350 units sold are assumed to come from opening stock (100), Purchase 1 (200), and 50 units of Purchase 2. Closing stock of 100 units comes from the remaining Purchase 2 units, valued at Rs 60 each. Closing stock value under FIFO = 100 x Rs 60 = Rs 6,000.

Under Weighted Average Cost: Total cost of goods available = (100x50) + (200x55) + (150x60) = Rs 25,000. Total units = 450. Weighted average cost per unit = Rs 25,000 / 450 = approximately Rs 55.56. Closing stock value under Weighted Average = 100 x Rs 55.56 = approximately Rs 5,556.

The two methods give different values purely because of how each assumes stock moves through the business. In periods of rising prices, FIFO tends to show a higher closing stock value (and higher profit) than Weighted Average.

NRV write-down scenario (illustrative): Suppose this product can now only be resold at Rs 52 per unit, with Rs 3 per unit in packing and transport costs.

NRV = Rs 52 minus Rs 3 = Rs 49 per unit

Since Rs 49 is lower than both the FIFO cost (Rs 60) and Weighted Average cost (Rs 55.56), Sample Traders must write down closing stock to Rs 49 per unit.

Revised closing stock value = 100 x Rs 49 = Rs 4,900

This shows exactly why the "lower of cost or NRV" rule exists: it prevents inventory from being carried above what it can genuinely be sold for.

Cost, Effort & Who Needs This in 2026

Getting inventory valuation right typically requires ongoing coordination between your stock team, who track physical quantities, and your accountant, who applies the correct costing method and NRV assessment. The effort depends on your business size: a small trader with a few SKUs will find this simpler than a manufacturer juggling raw materials, work-in-progress, and finished goods across locations.

Proper inventory valuation support becomes important for:

• Trading and manufacturing companies needing accurate COGS and closing stock figures for statutory and tax filings.
• Companies under statutory or tax audit, since inventory valuation is a standard high-scrutiny area.
• Businesses seeking bank loans or cash credit, where inventory is often pledged as security.
• Startups raising investment, where due diligence examines whether inventory is fairly stated and consistently valued.
• Businesses with seasonal or fast-depreciating stock (fashion, electronics, perishables), where NRV write-downs recur often.

The exact time and cost involved varies with transaction volume, SKU count, and whether you need a fresh valuation policy or an annual review. Rather than guessing at fees, it's best to get a tailored, transparent quote based on your specific business.

Key Distinctions / Comparisons

• FIFO vs Weighted Average: FIFO assumes the oldest stock is sold first, so closing stock reflects recent purchase prices; Weighted Average smooths all prices into one average applied uniformly. FIFO often suits perishables or batch-distinguishable goods; Weighted Average suits bulk or fungible inventory.
• FIFO vs Weighted Average vs LIFO (not allowed): Both FIFO and Weighted Average are permitted under AS 2 and Ind AS 2. LIFO is not recognised under Indian accounting standards at all and cannot be used for statutory statements or tax computation, regardless of software defaults.
• Cost vs Net Realisable Value (NRV): Cost is what you paid or spent producing the goods; NRV is what you can realistically recover by selling them, after remaining completion and selling costs. Indian standards require the lower of the two always.
• Consistency vs flexibility: You can choose between FIFO and Weighted Average, but you cannot switch arbitrarily year to year. Any change must be justified, applied consistently going forward, and disclosed.
• Item-level vs blanket valuation: The Lower of Cost or NRV comparison is normally applied item by item, not as one blanket figure, since blanket comparisons can mask write-downs needed on specific slow-moving items.

Common Mistakes Businesses Make

• Switching costing methods arbitrarily from year to year to manage reported profit, without genuine business justification.
• Ignoring NRV write-downs entirely and carrying all inventory at cost, even when certain stock is clearly damaged, obsolete, or out of season.
• Poor or incomplete stock records, making it impossible to accurately trace purchase dates and prices needed for FIFO or Weighted Average.
• Mixing costing methods across similar items within the same business without any logical basis.
• Treating LIFO-based internal reports as statutory figures, not realising accounting software defaults are not compliant for Indian statutory reporting.
• Failing to disclose the valuation policy in financial statement notes.
• Ignoring overheads and duties in cost computation, either under-including production overheads or wrongly including selling expenses.
• Not physically verifying stock against book records at year-end.

How Correct Inventory Valuation Helps Your Business and Funding

Correct, consistent inventory valuation strengthens your business well beyond compliance. It gives you accurate profits, a true picture of performance rather than a number distorted by valuation quirks, which matters for pricing, purchasing, and expansion decisions.

It makes audits smoother, since auditors specifically test inventory as a high-risk area, and a business with a clear, documented policy backed by proper stock records breezes through this compared to one where figures need reconstruction.

It improves loan and investor due diligence outcomes, since banks and investors both examine how inventory is valued and whether write-downs have been taken where needed. Confidence here translates into faster approvals and better terms.

It supports GST and tax compliance, since inventory figures tie into reconciliations, stock statements, and tax assessments. Clean valuation reduces the chances of queries or disputes.

In short, inventory valuation is not just an accounting formality, it is a foundational piece of financial credibility for any business that holds stock.

FAQ

Which inventory valuation methods are allowed in India?

Under AS 2 and Ind AS 2, only FIFO (First-In-First-Out) and Weighted Average Cost are permitted. Businesses can choose whichever suits their goods, but must apply it consistently across periods.

Is LIFO allowed under Indian accounting standards?

No. LIFO is explicitly not permitted under AS 2 or Ind AS 2, even though it is allowed under some other frameworks like US GAAP. If your software defaults to LIFO internally, that figure cannot be used in statutory financial statements or tax filings in India.

What does Net Realisable Value (NRV) mean?

NRV is the estimated selling price in the ordinary course of business, minus estimated costs still needed to complete the goods and costs necessary to sell them, like commission or freight. It represents what you can realistically recover from selling the stock.

Why must inventory be valued at the lower of cost or NRV?

This prevents a business from showing inventory above what it can actually be sold for. If the expected selling price falls below cost, the standards require writing the stock down to NRV so financial statements don't overstate assets or profits.

Can I change my inventory valuation method every year?

You technically can, but it is strongly discouraged unless there is a genuine business reason. Consistency is a core requirement under AS 2 and Ind AS 2, and any change must be justified and disclosed.

Does inventory valuation affect my income tax liability?

Yes, significantly. Closing stock value affects cost of goods sold and, therefore, reported profit. An incorrect or inconsistent method can lead to overstated or understated taxable profit, inviting scrutiny from the tax department.

Do small businesses and startups also need to follow AS 2 or Ind AS 2?

Most Indian companies, including small and mid-sized private limited companies, follow AS 2 unless they cross thresholds mandating Ind AS 2. Proprietorships and partnerships maintaining formal books also generally follow the same valuation principles as good practice.

How is inventory valuation different for manufacturers versus traders?

Traders mainly account for purchase cost and directly attributable costs like freight and duties. Manufacturers must also allocate production overheads into work-in-progress and finished goods cost, making the exercise more layered and usually requiring closer coordination with a qualified accountant.
