What is First-in, first-out (FIFO)?

An inventory costing method that assumes the items purchased or produced first are sold first.

Under FIFO, closing inventory is valued at the most recent costs; when prices are rising, cost of sales appears lower and profit higher. TMS 2 permits FIFO and weighted average cost but not LIFO.
