The Last In, First Out (LIFO) method is an inventory valuation technique commonly used in accounting and finance. Under LIFO, it is assumed that the most recently purchased items are the first to be sold. This means that items remaining in ending inventory are typically those that were acquired earlier.
The primary implication of LIFO is that the cost of goods sold (COGS) reflects more recent inventory costs, which can result in lower reported income during periods of rising prices. This contrasts with the First In, First Out (FIFO) method.
KaTeX Formulas for LIFO
One can calculate the COGS under LIFO using the following formula:
Where \( \sum \) represents the sum over recent acquisitions until the total quantity sold is matched.
Types of Valuation Methods
- LIFO: Assumes latest items are sold first.
- FIFO: Assumes earliest items are sold first.
- Weighted Average Cost: Averages cost of all items.
Special Considerations for LIFO
Tax Implications
LIFO can lower taxable income during periods of inflation, leading to tax deferral advantages. However, it is banned under International Financial Reporting Standards (IFRS) but permissible under Generally Accepted Accounting Principles (GAAP) in the United States.
Inventory Management
LIFO can result in older inventory items being reported at outdated values, potentially distorting the inventory’s current market value.
Examples of LIFO in Practice
Rising Inventory Prices
Consider a company that purchases inventory in January at $10 per unit, in June at $12 per unit, and in December at $15 per unit. If it sells 100 units in December, LIFO states that these units are considered sold at the December purchase price first:
Remaining inventory value is calculated with earlier purchase costs.
Falling Inventory Prices
LIFO may show higher income during periods of falling prices, as the latest (cheaper) costs are matched against revenues.
Historical Context
LIFO became prevalent in the United States under GAAP to provide tax advantages during inflationary periods. Its adoption fluctuates with economic conditions, regulatory changes, and corporate strategies.
Comparisons with FIFO
- FIFO method matches oldest inventory costs to revenues, which can result in reporting higher income when prices are rising.
- LIFO benefits companies in tax deferral during inflation but can complicate inventory management.
Related Terms

- Lower of Cost or Market (LCM): Inventory valuation rule ensuring items are reported at the lower cost or current market value.
- Cost of Goods Sold (COGS): Total cost of producing goods sold by a company.

Summary
The Last In, First Out (LIFO) method is an influential inventory valuation technique within U.S. accounting practices under GAAP. By assuming the most recently acquired items are sold first, LIFO can provide tax advantages during inflation but may lead to less accurate inventory valuations. It is crucial for companies to weigh the benefits and limitations when selecting LIFO, especially considering regulatory restrictions under IFRS.
