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.

MethodCOGS of 150 units soldValue of 50 on hand
FIFO$320$120
Weighted average$330$110
LIFO$340$100
Purchases: 100 units at $2.00 and 100 at $2.40. Average = $2.20.

mise values each count at the latest purchase price and shows average cost from your invoices.
