LIFO (Last-In-First-Out) cost is an inventory valuation method used in accounting to manage and assess the cost of inventory. This method assumes that the most recently produced items are the first to be sold, hence the name “Last-In-First-Out.”
Historical Context
The concept of LIFO cost originated in the early 20th century as businesses looked for ways to manage rising inventory costs. It gained significant popularity in the United States during periods of inflation, as it helps companies reduce taxable income by matching recent, higher costs against current revenues.
Types/Categories
- LIFO Liquidation: Occurs when older inventory costs are matched against current revenues.
- LIFO Reserve: The difference between inventory costs under LIFO and FIFO (First-In-First-Out).
Key Events
- 1939: The LIFO method was officially recognized in the U.S. tax code.
- 1970s-1980s: Extensive use of LIFO during periods of high inflation.
- 2009: International Financial Reporting Standards (IFRS) prohibited the use of LIFO.
Detailed Explanations
How LIFO Works
Under LIFO, the cost of the most recent inventory purchases is used to value the cost of goods sold (COGS). This means that during times of inflation, LIFO reports higher COGS and lower taxable income.
Mathematical Formula/Model
LIFO Cost Calculation Example
Cost of Goods Sold (COGS) under LIFO = Cost of Last Inventory Items Added
Ending Inventory Value under LIFO = Cost of Remaining Older Inventory Items

Importance
Using LIFO can provide significant tax advantages during periods of inflation. By using the most recently acquired (and often more expensive) inventory first, companies can match high costs with current revenues, thus lowering taxable income.
Applicability
LIFO is primarily used in industries where inventory costs frequently change, such as:
- Manufacturing
- Retail
- Wholesale
Examples
Example Scenario: A company purchases inventory as follows:
- 100 units @ $10/unit
- 200 units @ $15/unit
If the company sells 150 units, under LIFO, the COGS would be:
COGS = (150 units @ $15/unit) = $2250
Ending inventory value would be:
Ending Inventory = (100 units @ $10/unit) + (50 units @ $15/unit) = $1750
Considerations
- Tax Implications: LIFO can reduce taxable income but may also result in lower reported profits.
- Inventory Valuation: LIFO may not reflect current market values accurately.
- Compliance: Not allowed under IFRS, limiting its applicability internationally.

- Many companies in the U.S. switched to LIFO in the 1970s and 1980s during periods of high inflation to take advantage of tax benefits.

Summary
LIFO (Last-In-First-Out) cost is a crucial inventory valuation method in accounting, particularly useful during periods of inflation. Although it offers significant tax benefits, its applicability is limited internationally.
