First in first out method of costing (FIFO)

Definition of First in First out (FIFO) Method of Costing

First in First out (FIFO)  is an inventory costing method that assumes that the costs attached to the first goods purchased are the costs of the first goods sold.

The method assumes, the first cost received in stores is the first cost that goes out from the stores. In other words, cost of materials is charged to production in the order of purchases. The earlier costs recorded in materials ledger cards are used for costing requisitions and the balance is composed of units received later.

The first in first out method of costing (FIFO) is based upon the assumption that the various lots of materials purchased are used in the same order in which they are received i.e. the materials are issued from the oldest supply in stock in this method of costing. The materials used in a job or process are charged at the price of their original purchase. That is why this method is sometimes called “Original Price Method“.

The return from the factory to the store-room of excess materials issued for a particular job be treated as the oldest stock on hand and be placed in the materials card balance ahead of all the units in hand at the same price as it was issued to the factory.
