Quickly calculate your inventory's Cost of Goods Sold (COGS) and ending inventory value using the FIFO (First-In, First-Out) method. Understand how this essential accounting principle impacts financial statements, profitability, and stock valuation. Perfect for businesses managing their inventory efficiently and accurately.
Formula:
The FIFO (First-In, First-Out) inventory costing method assumes that the first units purchased or produced are the first ones sold or used. Consequently, the inventory remaining at the end of an accounting period consists of the most recently purchased or produced units.
Key Components & Formulas:
- Cost of Goods Sold (COGS): To calculate COGS, we start by expensing the cost of the earliest available inventory units until the total quantity sold has been accounted for.
COGS = SUM (Units Used from Layer * Cost Per Unit from Layer)
where 'Units Used from Layer' are taken from the oldest purchases first. - Ending Inventory Value: The total value of the remaining inventory is determined by the cost of the most recent purchases that are still on hand after sales.
Ending Inventory = SUM (Remaining Quantity in Layer * Cost Per Unit from Layer)
where 'Remaining Quantity in Layer' refers to units from the latest purchases.
This method directly impacts a company's reported profit and asset values, especially during periods of inflation or deflation.
