What is (FIFO) Method?
Introduction to FIFO Method
The FIFO (First-In-First-Out) method is an inventory valuation technique widely used in accounting and financial management. In this method, the first items added to inventory are the first ones to be removed or sold. Imagine a queue, where the first person to arrive is the first to leave; FIFO operates on a similar principle.
From a practical standpoint, when a company purchases or produces goods, the cost of the earliest acquired or produced items is assigned to the units sold first. This ensures that the cost of goods sold (COGS) reflects the most recent costs incurred by the business. FIFO is particularly relevant in industries with perishable or time-sensitive goods, as it mirrors the natural flow of inventory.
The FIFO method is straightforward and aligns with the chronological flow of inventory transactions. It provides a logical and easy-to-understand approach for tracking costs, aiding businesses in making informed decisions about pricing, profitability, and overall financial performance. While other inventory valuation methods exist, such as LIFO (Last-In-First-Out) and weighted average, FIFO remains a popular and widely accepted choice for its simplicity and adherence to real-world inventory flow.

Key Points of FIFO
There are several key points of fifo methods and here are some necessary key points given in the following:
- FIFO, which stands for First-In-First-Out, follows the principle that the first items added to inventory are the first ones to be sold. In other words, the costs associated with the earliest purchases or production are allocated to goods sold before costs from more recent acquisitions.
- FIFO provides a more accurate reflection of current costs in the cost of goods sold (COGS). This method assumes that the items remaining in inventory are the most recently acquired or produced, aligning with the natural flow of goods through a business.
- FIFO is widely accepted and often preferred for financial reporting purposes. It is compliant with generally accepted accounting principles (GAAP) and International Financial Reporting Standards (IFRS), making it a suitable choice for businesses aiming for consistency and transparency in their financial statements.
- The FIFO method is simple to understand and apply. It mimics the intuitive flow of goods in many industries and is particularly suitable for businesses with straightforward inventory systems. This simplicity makes it accessible to small businesses as well as large enterprises.
- In periods of inflation, FIFO tends to result in a lower cost of goods sold compared to alternative methods like LIFO (Last-In-First-Out). This can be advantageous as it may lead to higher reported profits and reduced tax liabilities. Consequently, FIFO is often favored when inflationary pressures are a consideration for businesses.
Understanding FIFO Method
The FIFO (First-In-First-Out) method is a principle in inventory management that ensures the oldest units in stock are the first to be used or sold. It operates on the idea that the items received or produced first are the ones to be consumed or sold first, mirroring the natural flow of goods in most businesses. In practical terms, when calculating the cost of goods sold (COGS), FIFO assigns the cost of the earliest inventory on hand to items sold. This approach results in a more accurate representation of current costs, especially in industries where the chronological order of inventory matters.
One can envision FIFO as a queue, where the first entity to join is the first to exit. This method is straightforward, easy to understand, and aligns well with the chronological flow of business transactions. Its simplicity makes it particularly suitable for businesses with straightforward inventory systems. Moreover, FIFO is widely accepted in financial reporting and accounting standards, enhancing its credibility. In periods of inflation, FIFO can mitigate the impact on profits by assigning lower costs to goods sold, making it a strategic choice for businesses navigating varying economic conditions.
Calculating in FIFO Method
Calculating the cost of goods sold (COGS) using the FIFO (First-In-First-Out) method involves assigning the cost of the oldest inventory first. The formula for calculating the COGS under FIFO is relatively straightforward:
COGS=Cost of Oldest Inventory×Number of Units SoldCOGS=Cost of Oldest Inventory×Number of Units Sold
To break it down:
Identify the Cost of Oldest Inventory:
- Determine the cost per unit of the oldest inventory in stock. This is usually based on the purchase or production cost of the earliest batch of goods.
Determine the Number of Units Sold:
- Count the number of units sold during a specific period.
Apply the FIFO Formula:
- Multiply the cost per unit of the oldest inventory by the number of units sold to calculate the COGS.
Example:
Let’s say a company purchases or produces goods as follows:
- January 1: Purchased 100 units at $5 each
- February 1: Purchased 150 units at $6 each
- March 1: Purchased 200 units at $7 each
If 120 units are sold in March, the COGS under FIFO will be calculated as:
COGS=($5×100)+($6×20)=$500+$120=$620COGS=($5×100)+($6×20)=$500+$120=$620
This calculation reflects the fact that the first 100 units at $5 each and 20 units at $6 each were the ones sold, following the FIFO principle.
