Last in, first out (LIFO)

What is last in, first out (LIFO)?

Last in, first out (LIFO) is an inventory accounting method that assumes the newest stock is sold first, so cost of goods sold reflects the latest costs. It is allowed under US accounting rules (GAAP) but not under International Financial Reporting Standards (IFRS).

How it works

Companies choose LIFO mainly because, when costs rise, it raises reported cost of goods sold and lowers taxable income. LIFO is only an accounting assumption: the warehouse still ships the oldest stock first.

Last in, first out (LIFO) example

A distributor buys 100 units at $10, then 100 more at $12, and sells 100. Cost of goods sold is $1,200 under LIFO and $1,000 under FIFO.
