FIFO (First In First Out)

Last updated on 

FIFO, or First-In-First-Out, is a method of inventory and cost accounting that is widely used in businesses and organizations of all sizes. The FIFO method is one of the most popular inventory valuation methods and is based on the principle that the first item of inventory that is purchased or produced is the first item that is sold or used. This method assumes that the oldest inventory items are sold or used first, which allows companies to accurately value their inventory and calculate their cost of goods sold.

In this article, we will explore the concept of FIFO in detail, including its history, how it works, its advantages and disadvantages, and some examples of how it is used in different industries.

History of FIFO

The concept of FIFO has been around for centuries and is thought to have originated in the early days of commerce and trade. The first recorded use of FIFO can be traced back to the 14th century, when Italian merchants used the method to account for the cost of their goods.

The concept of FIFO became more popular in the 20th century with the advent of modern accounting systems and the growth of manufacturing industries. Today, FIFO is widely used in businesses of all sizes and across a variety of industries.

How FIFO Works

FIFO works by assuming that the first items of inventory that are purchased or produced are the first items that are sold or used. This means that the cost of the oldest inventory items is used to calculate the cost of goods sold (COGS), while the cost of the newest inventory items is used to calculate the value of the remaining inventory.

For example, let's say that a company produces 1,000 units of a product in January at a cost of $10 per unit. In February, the company produces another 1,000 units of the same product at a cost of $12 per unit. If the company sells 500 units of the product in March, under the FIFO method, the COGS for these sales would be calculated using the cost of the January production run, or $10 per unit.

In this example, the remaining inventory would be valued using the cost of the February production run, or $12 per unit. This means that the value of the remaining 500 units of inventory would be $6,000 (500 units x $12 per unit).

Advantages of FIFO

There are several advantages to using the FIFO method for inventory valuation and cost accounting. These include:

  1. Accuracy: The FIFO method is considered to be one of the most accurate inventory valuation methods. By using the cost of the oldest inventory items to calculate the COGS, companies can ensure that their financial statements accurately reflect the true cost of the goods sold.
  2. Easy to understand: The FIFO method is relatively easy to understand and implement, making it a popular choice for businesses of all sizes.
  3. Conforms to GAAP: The FIFO method is in accordance with Generally Accepted Accounting Principles (GAAP) and is widely accepted by auditors, investors, and other stakeholders.
  4. Tax benefits: In some cases, the FIFO method can provide tax benefits by reducing the amount of taxable income for a company.

Disadvantages of FIFO

While there are many advantages to using the FIFO method, there are also some potential drawbacks to consider. These include:

  1. Unrealistic assumptions: The FIFO method assumes that the oldest inventory items are sold first, which may not always be the case in practice. In some industries, such as perishable goods, this assumption may not hold true.
  2. Inventory fluctuations: The FIFO method can result in fluctuations in inventory values, especially if there are significant price changes over time. This can make it difficult for companies to accurately value their inventory and plan for future sales and production.
  3. Complexity: While the FIFO method is relatively simple to understand and implement, it can become more complex when dealing with inventory that has been partially used or assembled into finished products. This can make it more difficult to accurately track the cost of goods sold and value remaining inventory.
  4. Potential for manipulation: In some cases, the FIFO method can be manipulated by companies to inflate profits or reduce taxable income. For example, a company could intentionally hold onto older, lower-cost inventory items and sell newer, higher-cost items in order to increase profits.

Examples of FIFO

FIFO is used in a variety of industries, including manufacturing, retail, and food service. Here are a few examples of how FIFO is used in practice:

  1. Manufacturing: A manufacturing company produces 1,000 units of a product in January at a cost of $10 per unit. In February, the company produces another 1,000 units of the same product at a cost of $12 per unit. If the company sells 500 units of the product in March, under the FIFO method, the COGS for these sales would be calculated using the cost of the January production run, or $10 per unit.
  2. Retail: A retail store purchases 100 shirts in January for $10 each and another 100 shirts in February for $12 each. If the store sells 50 shirts in March, the COGS for these sales would be calculated using the cost of the January purchase, or $10 per shirt.
  3. Food service: A restaurant purchases 10 pounds of ground beef for $2 per pound in January and another 10 pounds for $3 per pound in February. If the restaurant uses 5 pounds of ground beef in March, the COGS for this usage would be calculated using the cost of the January purchase, or $2 per pound.

Conclusion

FIFO is a popular inventory valuation method that is widely used in businesses of all sizes and across a variety of industries. While there are some potential drawbacks to using the FIFO method, including unrealistic assumptions and inventory fluctuations, it is considered to be one of the most accurate and easy-to-understand inventory valuation methods available. By understanding how FIFO works and its advantages and disadvantages, businesses can make informed decisions about how to value their inventory and calculate their cost of goods sold.
