Inventory Valuation Methods: FIFO, Average, Specific
By mise · Updated September 29, 2026
Quick answer: inventory valuation puts a cost on the stock you hold. The common methods are FIFO, weighted average and specific identification (LIFO is allowed under US GAAP but not IFRS). Always value at cost, never at retail price.
Valuation changes your balance sheet, COGS and profit. Picking the method is not a detail.
| Method | COGS of 150 units sold | Value of 50 on hand |
|---|---|---|
| FIFO | $320 | $120 |
| Weighted average | $330 | $110 |
| LIFO | $340 | $100 |
