How Does it Work?

When there are multiple items in the inventory which require to be allocated for particular products, the products which are purchased or bought earlier would be considered for the collection of the cost for the product.

How to Calculate FIFO?

To calculate FIFO, the price of the oldest inventory needs to be traced, and then the cost prices of each unit are multiplied with the units of inventory sold. Then the amount arrived would be the price of the inventory, and the remaining raw material units would be used for next inventory sales.


To arrive at the cost of sales, inventory plays a significant part in it. An inventory constitutes multiple products or items or self-made goods of the company. So, let’s assume article A has been used raw material for product Y. The Y has 10000 pieces in the finished goods segments, and within the production span, the company has bought X twice in a lot of 4000 pcs each. The first 7000 of X costed the Company at a rate of $10 each, and the remaining 7000 has cost $12 each. So, for calculating the price of Y for the first 10000 units, $10 price would be considered for the first lot of 4000 pieces and $12 for the remaining 6000 pieces.

Other Methods

There are various other methods of valuation except for FIFO, such as LIFOLIFOLIFO (Last In First Out) is one accounting method for inventory valuation on the balance sheet. LIFO accounting means inventory acquired at last would be used up or sold first.read more and Weighted Average inventory method.

  • LIFO is considered as last in first out. It is generally used in the inflationary economy due to an increase in the prices consistently. It helps in the price checking function of the goods and thus reflects a better inventory pricing and also keeps the profits in the check.
  • Another widely used method apart from FIFO is Weighted Average. Weighted Average put weights on the prices of products when these are purchased. Also, In a way, it averages out the prices and removes the bias of earlier or later buys. It helps in providing the real picture of the profits and losses in the financial statements.

Difference Between FIFO and LIFO

  • LIFO or Last In First Out is the opposite of FIFO or First in First Out. In LIFO, the most recent inventory is used for calculation of the Cost of Goods Sold. This method could be used once the cost of inventory is rising over the period, and most probably, the cause is inflation.
  • If the FIFO method would be used, the cost of goods sold would be comparatively lower to that of the current market prices and would reflect higher profit. To resolve the mismatch of prices, the LIFO method is used in such situations.


  • In maximum industries, FIFO is used because there is no alarming situation where inflation is rising at a higher pace, or the prices of the goods have suddenly shot up.
  • In another situation, the FIFO works well because it shows the real cost position as used by the management. It is based on the principle that goods have a shelf life, and if the goods that arrived earlier were not used, it would perish or lose their quality. So, to apply that in the costing world too, the FIFO method is used.
  • It also helps to rule out products that came earlier than others to remove the possibility of the minimization of the wastage by taking goods arrived in the chronological order.
  • Again, it is a simple idea, and anybody with even a layman’s brain would be able to understand it. It is like deducting on a priority basis of arrival. It is widely used and thus removes the inconsistencies faced by using different methods.
  • It removes the manipulation in the accounts as the records available would certify the costs received earlier. Again, most of the time, if the prices are increasing in the market, FIFO tends to increase the profit of the entity, as the goods arrived earlier must have been bought at a lower price.


Few disadvantages of the FIFO method is as follows:


Though the FIFO has some disadvantages in the inflationary price movements, it still provides a lot to the valuation world because due to the simplicity, wide acceptance, and better presentation of the financial records, it poses a better valuation option in comparison to many methods. Also, it is being approved by various tax authorities across nations, making it a suitable choice in selection policies of valuation.
