LIFO (Last In, First Out)

Dive deep into LIFO (Last In, First Out), a unique inventory valuation approach. Understand its mechanics, benefits, criticisms, and comparison with other methods.

Introduction to LIFO

The inventory management and accounting world is replete with methodologies, each serving unique needs and contexts. Among these, LIFO, or “Last In, First Out,” stands out as a distinct approach to inventory valuation. At its core, LIFO operates on a principle where the most recent inventory acquired or produced is the first to be sold or consumed, leaving the older stock in inventory.

Mechanics of LIFO

How LIFO Works

Imagine a stack of boxes where every new box is placed on top. When it’s time to use or sell a box, you’d naturally take the topmost one, which is the last one you placed. This analogy encapsulates the LIFO methodology.

In more technical terms, if a company buys a product at different prices over a quarter and then sells a portion of that inventory, the cost of the most recently purchased products becomes the cost of goods sold.

LIFO in Financial Statements

On a company’s balance sheet, inventory is typically valued at a cost. With LIFO, the remaining inventory might be valued at older, possibly lower, costs. This directly impacts the reported profit margins and tax liabilities.

Benefits of LIFO

Tax Advantages

In periods of rising prices, LIFO tends to result in a higher cost of goods sold, which translates to lower reported profits and, consequently, lower taxes. It’s an attractive proposition for companies operating in inflationary economies.

Matching Current Costs

LIFO allows businesses to match current sales with current costs, ensuring that the income statement reflects the current market conditions.


Criticisms and Limitations of LIFO

Not Actual Physical Flow

LIFO doesn’t always represent the actual flow of inventory, especially if products are perishable or if items can become obsolete.

Lower Reported Profits

While reduced profits might offer tax advantages, they can also paint a less favorable picture of a company’s financial health to investors and stakeholders.

International Differences

LIFO is not universally accepted. For instance, the International Financial Reporting Standards (IFRS) prohibit the use of LIFO.


Comparing LIFO with Other Methods


The most common comparison is between LIFO and FIFO (“First In, First Out”). FIFO operates on the opposite principle, where the oldest stock is sold first. It results in different financial outcomes, especially in terms of tax liabilities and reported profits.

LIFO vs. Weighted Average

Another method is the Weighted Average, where the total cost of items available for sale is divided by the number of units available, determining an average cost. It smoothens out price fluctuations and offers a middle-ground valuation.

Practical Considerations for Implementing LIFO

Companies contemplating the adoption of LIFO should consider:

  1. Nature of Inventory: Perishable items might not be suitable for LIFO.
  2. Economic Conditions: LIFO can be beneficial in inflationary conditions but less so when prices are stable or declining.
  3. Accounting and Reporting Standards: Ensure that local accounting standards and regulations permit the use of LIFO.
