Also known as: FIFO

Quick Summary

FIFO stands for "first in, first out". This is an accounting method used to value inventory. In this system, the oldest inventory items are assumed to be sold first. This means that the cost of goods sold is based on the cost of the earliest purchased items, while the remaining inventory is valued at the cost of the most recently acquired items. This contrasts with LIFO (last-in, first-out), where the newest inventory items are assumed to be sold first.123
