Historical Context
The Last-In-First-Out (LIFO) method of inventory valuation dates back to the early 20th century, gaining prominence during periods of inflation. Businesses adopted LIFO to better match current costs with revenues, thereby reflecting a more realistic financial picture.
Types/Categories of LIFO
- Specific Identification LIFO: This method tracks the actual cost of individual items.
- Pooled LIFO: Grouping similar inventory items and calculating a single LIFO layer for the pool.
- Dollar-Value LIFO: Using monetary units instead of physical units to value inventory layers, which allows for inflation adjustments.
Key Events
- 1939: LIFO was officially recognized by the Internal Revenue Service (IRS) in the United States.
- 2003: The International Accounting Standards Board (IASB) disallowed LIFO under IFRS.
Detailed Explanation
LIFO is an inventory costing method where the costs of the most recently acquired items are the first to be assigned to the cost of goods sold. Consequently, the inventory left on hand at the end of the accounting period reflects the costs of the oldest inventory.
Mathematical Formulas/Models
- Cost of Goods Sold (COGS) under LIFO:
$$ \text{COGS} = \text{Last Purchase Costs} \times \text{Units Sold} $$
- Ending Inventory under LIFO:
$$ \text{Ending Inventory} = \text{Total Inventory Cost} - \text{COGS} $$

Importance and Applicability
- Matching Costs with Revenues: LIFO helps in better matching recent costs with current revenues.
- Tax Benefits: During inflationary periods, LIFO results in higher COGS and lowers taxable income.
Examples
- Retail Industry: For a retailer facing high inflation, using LIFO can result in significant tax savings.
- Manufacturing: Manufacturing firms may prefer LIFO to align costs of materials with production sales closely.
Considerations
- Complexity: LIFO can be administratively cumbersome to maintain.
- International Standards: Not accepted under IFRS, limiting its global applicability.
- Financial Reporting: Can lead to lower reported profits during inflationary periods.
Related Terms
- First-In-First-Out (FIFO): An inventory valuation method where the earliest purchased items are the first to be used or sold.
- Average Cost Method: An approach to inventory costing that averages out the cost of all items available for sale.
Comparisons
| Aspect | LIFO | FIFO |
|---|---|---|
| Cost Flow Assumption | Latest costs are used first | Earliest costs are used first |
| Impact on Taxes | Can lower taxable income | Higher taxable income during inflation |
| Compliance | Not IFRS compliant | IFRS compliant |
Interesting Facts
- Warren Buffett’s Preference: The renowned investor prefers FIFO over LIFO due to its higher reported profits and straightforward application.
Inspirational Story
In the 1970s, during a period of high inflation, many US companies switched to LIFO to manage their financial performance better. This strategic move helped them navigate economic challenges and sustain growth.
Famous Quotes
“Inflation is taxation without legislation.” - Milton Friedman
Proverbs and Clichés
- “A penny saved is a penny earned.”
Expressions
- “Top of the heap”: Reflects the utilization of the most recent costs first.
Jargon and Slang
- Layering: Refers to how LIFO manages different cost layers of inventory.
FAQs
Q: Why isn’t LIFO accepted under IFRS? A: IFRS aims for transparency and comparability in financial statements, and LIFO can obscure this due to the manipulation of income and inventory levels.
Q: How does LIFO affect cash flow? A: LIFO can improve cash flow during inflationary periods due to lower taxable income and thus lower tax payments.

Final Summary
The Last-In-First-Out (LIFO) cost method is a valuable accounting approach that aligns recent costs with current revenues, particularly beneficial during inflationary periods. Although it has significant advantages like tax savings, it also presents challenges, including complexity and limited global acceptance. Understanding LIFO’s mechanics and implications can significantly aid businesses in strategic financial planning.
