What Is the FIFO Method?

The FIFO method, also known as First In, First Out, is a popular inventory valuation method used by companies worldwide. It follows the principle that the assets produced or acquired first are sold, used, or disposed of first. This means that the oldest stock is the first to be sold, ensuring a proper rotation of inventory.

How Does First In, First Out Work?

The FIFO method operates on the assumption that the cost of inventory increases over time. By selling the oldest stock first, companies can accurately calculate the cost of goods sold (COGS) based on the cost of the earliest purchased or produced items. This approach is particularly useful in industries where the value of inventory tends to rise, such as food and perishable goods.

Example of FIFO

Let's consider an example to better understand how FIFO works. Imagine you own a grocery store, and you stock up on apples throughout the year. You purchase three batches of apples at different prices: the first batch at $1 per apple, the second batch at $1.50 per apple, and the third batch at $2 per apple.

If you sell ten apples, according to the FIFO method, you would sell the ten apples from the first batch you purchased at $1 each. This ensures that the cost of goods sold reflects the oldest inventory and accurately represents the expenses incurred.

FIFO vs. LIFO

Another commonly used inventory valuation method is LIFO, which stands for Last In, First Out. While FIFO assumes the cost of inventory increases over time, LIFO follows the opposite principle. LIFO assumes that the most recently purchased or produced items are sold first, resulting in a different valuation of inventory and COGS.

Other Valuation Methods

Aside from FIFO and LIFO, there are several other inventory valuation methods used by businesses:

  • Weighted Average Cost
  • Specific Identification
  • Standard Costing
  • Retail Inventory Method

Each method has its advantages and disadvantages, and companies choose the one that best suits their operations and financial reporting requirements.

Why Is the FIFO Method Popular?

The FIFO method is popular among businesses for several reasons:

  • Accurate COGS Calculation: FIFO ensures that the cost of goods sold reflects the actual expenses incurred by selling the oldest inventory first.
  • Tax Benefits: In countries where inventory valuation affects tax calculations, FIFO can result in lower taxable income compared to other methods.
  • Realistic Profit Margins: By accurately accounting for the cost of goods sold, FIFO provides a more realistic representation of profit margins.

What Are the Other Inventory Valuation Methods?

Aside from FIFO, LIFO, and the other methods mentioned earlier, there are various inventory valuation methods available:

  • Moving Average Cost
  • Just-in-Time (JIT)
  • Backflush Costing
  • Activity-Based Costing

Each method has its unique characteristics and applicability in specific industries or business models.

How Is FIFO Calculated?

Calculating FIFO is relatively straightforward. Here's the step-by-step process:

  1. Record the quantity and cost of each batch of inventory purchased or produced.
  2. When a sale occurs, identify the oldest batch of inventory still available.
  3. Multiply the quantity sold by the cost per unit of the oldest batch to determine the cost of goods sold.
  4. Adjust the remaining inventory balance by subtracting the quantity sold from the oldest batch.
  5. Repeat these steps for each subsequent sale, always using the oldest available batch of inventory.

The Bottom Line

The FIFO method is a widely adopted inventory valuation method that ensures accurate cost of goods sold calculations. By selling the oldest inventory first, businesses can maintain proper inventory rotation and reflect the true expenses associated with sales. Understanding the FIFO method is crucial for businesses looking to effectively manage their inventory and financial reporting.
