Inventory management plays a vital role in the success of any business, and one of the most widely used methods for tracking inventory is the First-In-First-Out (FIFO) method. In this article, we’ll explore step by step how to calculate ending inventory using the FIFO method.

Step 1: Understand the FIFO Method

The basic concept of the FIFO method is that the oldest items in inventory are sold first. This means that the cost of goods sold (COGS) is based on the costs of the earliest goods purchased, while the ending inventory represents the costs of the latest available items.

Step 2: Segregate Purchases by Date

Organize your purchases according to their purchase dates. This will help you easily identify which items are considered ‘first-in.’ Start with the earliest purchases and move towards more recent ones.

Step 3: Calculate Cost of Goods Sold (COGS)

To determine COGS using FIFO, you should multiply the number of units sold by their respective costs per unit, according to their chronological purchase order. Perform this calculation sequentially until all sold items have been accounted for.

Example:

Suppose you sold 100 units during a given period, and your inventory purchase history is as follows:

– 50 units at a cost of $10 per unit

– 75 units at a cost of $12 per unit

Using FIFO method, COGS would be calculated as follows:

(50 units * $10) + (50 remaining units * $12) = $1,100

Step 4: Calculate Remaining Inventory Units

Subtract the total quantity of units sold from your total purchased inventory quantity.

Example:

Total purchased inventory: 50+75 = 125 units

Total sold units: 100

Remaining inventory units = 125 – 100 = 25 units

Step 5: Calculate the Ending Inventory Value

To calculate the ending inventory value, multiply the remaining unsold units with their respective unit costs, according to the FIFO method.

Example:

In our example, there are 25 remaining units (from the 75 units at $12 per unit batch):

Ending Inventory Value: 25 units * $12 = $300

Conclusion:

Calculating ending inventory using the FIFO method enables businesses to maintain an accurate and up-to-date record of their inventory value. Following these steps will allow you to effectively manage your inventory, ensuring that your financial records are precise and help improve overall business operations.
