FIFO (First In, First Out)

What is FIFO (First In, First Out)?

An inventory costing method where the oldest inventory items are sold or used first.

FIFO (First In, First Out) is an inventory costing method where the oldest inventory items are sold or used first. This method assumes that the goods purchased or produced first are the ones that are sold or utilized first, which helps in tracking the cost of goods sold (COGS) and inventory valuation.

Key Principles of FIFO

  • Oldest Inventory First: Items that were acquired or produced first are sold or used before newer inventory.
  • Cost Flow Assumption: The cost associated with the oldest inventory items is used to calculate the cost of goods sold, while the remaining inventory reflects the cost of the most recent purchases.
  • Reflects Actual Flow: FIFO often matches the actual flow of goods in many businesses, especially those dealing with perishable items or products with expiration dates.
  • Benefits of FIFO

  • Accurate Inventory Valuation: FIFO provides a more accurate valuation of current inventory, as it reflects recent purchase costs.
  • Higher Profit Margins: During periods of inflation, FIFO results in lower COGS and higher profit margins, as older, cheaper inventory is matched against current sales revenue.
  • Reduced Obsolescence: FIFO helps reduce the risk of inventory obsolescence, particularly for products with limited shelf life.
  • Simpler Accounting: The method is straightforward and easier to implement and understand.
  • Challenges of FIFO

  • Tax Implications: Higher reported profits under FIFO can lead to higher tax liabilities, as lower COGS increases taxable income.
  • Mismatch with Physical Flow: In some industries, the physical flow of goods may not match the FIFO assumption, leading to discrepancies in cost tracking.
  • Increased Complexity: During times of fluctuating prices, tracking and managing inventory costs can become more complex.
  • Example of FIFO Calculation

    Suppose a company has the following inventory transactions:

  • Beginning Inventory: 100 units at $10 each
  • Purchase 1: 200 units at $12 each
  • Purchase 2: 150 units at $15 each
  • If the company sells 250 units, the cost of goods sold (COGS) would be calculated as follows:

    1.      First, sell the 100 units from the beginning inventory:

    100 units × $10 = $1,000

    2.      Next, sell 150 units from Purchase 1:

    150 units × $12 = $1,800

    Total COGS under FIFO: $1,000 + $1,800 = $ 2,800

    The remaining inventory would be:

  • 50 units from Purchase 1 at $12 each
  • 150 units from Purchase 2 at $15 each
  • FIFO in Financial Statements

  • Income Statement: Under FIFO, the COGS will reflect the cost of older inventory, which can impact gross profit and net income.
  • Balance Sheet: The ending inventory will be valued based on the most recent purchase costs, providing a more current and accurate valuation of inventory assets.
  • FIFO is a widely used and accepted inventory costing method that aligns well with the actual physical flow of goods in many businesses. It provides several advantages in terms of accurate inventory valuation, profit reporting, and reducing obsolescence. However, businesses must also consider the potential tax implications and the complexity of managing inventory costs under this method. By understanding and effectively implementing FIFO, companies can achieve more accurate financial reporting and efficient inventory management.
