Inventory valuation is the process of determining the monetary value of unsold stock held by a business at the end of an accounting period. Accounting standards such as IAS 2 (International), Ind AS 2 (India), and AS 2 (old Indian GAAP) govern inventory valuation to ensure uniformity and reliability. These standards require inventories to be valued at the lower of cost or net realizable value (NRV). Cost includes purchase price, conversion costs, and other expenses incurred to bring inventory to its present location and condition. NRV represents the estimated selling price minus costs of completion and selling. Proper inventory valuation prevents overstating profits, ensures compliance with accounting principles, and provides fair representation of financial position, helping investors and management make informed decisions.
Inventory Valuation through Accounting Standards:
-
IAS 2 – Inventories (International Accounting Standard)
IAS 2, issued by the International Accounting Standards Board (IASB), provides guidelines for inventory valuation. It requires inventories to be valued at the lower of cost and net realizable value (NRV). Cost includes purchase costs, conversion costs, and other costs to bring inventory to its current condition and location. NRV is the estimated selling price minus estimated costs of completion and selling expenses. IAS 2 also specifies acceptable cost formulas, such as FIFO (First-In, First-Out) and Weighted Average Cost. The standard prohibits the use of LIFO (Last-In, First-Out) due to inconsistency with actual flow of goods. By applying IAS 2, companies present inventories fairly, avoid overstating profits, and ensure comparability of financial statements globally, thereby enhancing transparency and investor confidence.

Ind AS 2 – Valuation of Inventories (India)
Ind AS 2, converged with IAS 2, governs inventory valuation in India under the Companies (Indian Accounting Standards) Rules, 2015. It mandates valuing inventories at the lower of cost and net realizable value (NRV), similar to IAS 2. The cost includes purchase price, duties, transport, handling, and production overheads, while NRV is the estimated selling price minus costs of completion and selling. Acceptable cost formulas under Ind AS 2 are FIFO and Weighted Average Cost, while LIFO is not allowed. Ind AS 2 applies to all inventories except work-in-progress under construction contracts, financial instruments, and biological assets. It ensures consistency, compliance with international practices, and reliability of financial reporting, making financial statements more useful for investors, regulators, and decision-makers in India.

AS 2 – Valuation of Inventories (Old Indian GAAP)
AS 2, issued by the ICAI (Institute of Chartered Accountants of India), earlier provided the framework for inventory valuation in India before the adoption of Ind AS. It also required inventories to be valued at the lower of cost and net realizable value. Cost included purchase, conversion, and other necessary expenses, while NRV represented the selling price less estimated costs of completion and disposal. AS 2 permitted both FIFO and Weighted Average Method for cost calculation, while LIFO was disallowed. Though largely similar to Ind AS 2, AS 2 applied only to companies not covered under Ind AS implementation. It ensured prudence in accounting, prevented overstatement of profits, and offered reliable valuation guidance under the traditional Indian GAAP framework.
Formulas:
1. First In, First Out (FIFO) Method
Under FIFO, it is assumed that the oldest inventory (purchased first) is sold first, while the most recent purchases remain in stock. According to Ind AS 2 and IAS 2, this method is allowed for inventory valuation. It aligns with the natural flow of goods and ensures closing stock reflects recent market prices. This provides a more realistic balance sheet value but may increase profits in inflationary conditions, leading to higher tax liability.
Formula:
-
COGS = Cost of earliest inventory purchased × Units sold
-
Closing Stock = Cost of most recent purchases × Units unsold
2. Last In, First Out (LIFO) Method (Not Permitted under IAS 2/Ind AS 2, allowed in some US GAAP)
LIFO assumes that the latest inventory purchased is sold first, while older stock remains in closing inventory. Although not accepted by IAS 2 and Ind AS 2, it is still used under U.S. GAAP (ASC 330). It reduces taxable income during inflation since cost of goods sold (COGS) reflects recent higher prices. However, it understates inventory value on the balance sheet.
Formula:
-
COGS = Cost of latest inventory purchased × Units sold
-
Closing Stock = Cost of earliest purchases × Units unsold
3. Weighted Average Cost Method
This method averages the cost of all available units for sale during the period and assigns the same cost to both COGS and closing stock. IAS 2 and Ind AS 2 permit this method because it smoothens price fluctuations. It is widely used where inventory items are indistinguishable, such as fuel, chemicals, or grains. It prevents extreme profit variations but may not reflect current market value.
Formula:
-
Weighted Average Cost per Unit = Total Cost of Goods Available ÷ Total Units Available
-
COGS = Weighted Average Cost × Units Sold
-
Closing Stock = Weighted Average Cost × Units Remaining
4. Specific Identification Method
Under this method, each item of inventory is valued at its actual purchase cost. It is allowed under IAS 2 and Ind AS 2 but is practical only when items are unique, high-value, or easily identifiable, such as cars, jewelry, or real estate. This method provides the most accurate valuation since revenue is directly matched with the exact cost of the item sold. However, it may be time-consuming for large volumes of stock.
Formula:
-
COGS = Actual Cost of Specifically Sold Items
-
Closing Stock = Actual Cost of Items Remaining
