How to Do LIFO A Simple Guide to Understanding and Applying the Last-In, First-Out MethodWhen it comes to inventory management and accounting, understanding different methods for tracking stock and costs is essential. One popular method is LIFO, which stands for Last-In, First-Out. This approach affects how businesses calculate their cost of goods sold (COGS) and manage inventory. Whether you’re a student, business owner, or finance professional, knowing how to do LIFO properly can help you make better decisions and comply with accounting standards.

This topic will explain what LIFO is, why it matters, and how to apply it step-by-step. You’ll also learn its advantages and limitations, all presented in an easy-to-understand way.

What is LIFO?

LIFO is an inventory valuation method where the most recently purchased or produced items are considered sold first. In other words, the last items added to inventory are the first ones to be removed when a sale happens.

For example, if a store buys 10 units of a product in January and another 10 units in February, under LIFO, the February units will be considered sold before January’s.

Why Use LIFO?

  • Tax benefits In times of rising prices, LIFO can reduce taxable income by matching recent higher costs with current revenues.

  • Better matching of current costs with revenues Since recent costs are matched with sales, the profit margin reflects current market conditions.

  • Inventory management Helps companies track their inventory cost flow realistically in certain industries.

However, LIFO is not allowed under International Financial Reporting Standards (IFRS) and is mainly used in the United States under Generally Accepted Accounting Principles (GAAP).

Key Terms to Know

  • Inventory The goods a company holds for sale.

  • Cost of Goods Sold (COGS) The direct costs attributable to goods sold during a period.

  • Ending Inventory The value of goods still on hand at the end of the accounting period.

How to Do LIFO Step-by-Step Guide

Step 1 Gather Your Inventory Data

To apply LIFO, start by collecting detailed information about your inventory purchases, including

  • Purchase dates

  • Quantity bought

  • Cost per unit

Having this information organized in chronological order is important.

Step 2 Record Sales Chronologically

List all sales transactions, showing the quantity sold and the date. This will help determine which inventory batches are used first based on LIFO rules.

Step 3 Assign Costs to Sold Units Using LIFO

Under LIFO, you assign costs starting from the most recent purchases backward.

Example

  • January 1 100 units purchased at $5 each

  • February 1 100 units purchased at $6 each

  • March 1 Sold 150 units

In this case, the first 100 units sold are from February at $6, and the remaining 50 units come from January at $5.

Step 4 Calculate Cost of Goods Sold (COGS)

Multiply the quantity sold from each batch by its purchase price, then add these amounts to find the total COGS.

Using the example

  • 100 units x $6 = $600

  • 50 units x $5 = $250

  • Total COGS = $850

Step 5 Calculate Ending Inventory

Subtract the quantity sold from total inventory and value the remaining units using the oldest purchase prices.

From the example, after selling 150 units

  • Remaining inventory = 50 units from January at $5 each

  • Ending Inventory = 50 x $5 = $250

Advantages of Using LIFO

  • Tax savings in inflation Higher recent costs reduce taxable income.

  • Reflects current market prices Gives a more accurate picture of profit margins during inflation.

  • Simplifies accounting for certain industries Particularly where older inventory is less relevant.

Limitations of LIFO

  • Not allowed internationally IFRS prohibits LIFO, so it’s mostly used in the US.

  • Inventory undervaluation Ending inventory might be valued at outdated costs, making financial statements less reflective of true market value.

  • Complexity Managing LIFO requires careful record-keeping and can be more complicated than other methods like FIFO (First-In, First-Out).

Common Industries That Use LIFO

LIFO is popular in industries where inventory costs frequently change, such as

  • Retail

  • Manufacturing

  • Oil and gas

These industries benefit from matching recent higher costs against revenues to reduce tax liabilities.

LIFO vs FIFO What’s the Difference?

While LIFO sells the newest inventory first, FIFO assumes the oldest inventory is sold first. During inflation, FIFO usually results in lower COGS and higher profits, but higher taxes. Choosing between them depends on your business needs and tax strategy.

Tips for Applying LIFO Successfully

  • Maintain detailed and organized records of all purchases and sales.

  • Use inventory management software that supports LIFO accounting.

  • Consult with an accountant to ensure compliance with tax laws.

  • Regularly review inventory to avoid stock discrepancies.

Understanding how to do LIFO is important for businesses aiming to manage inventory and taxes effectively. By following the steps outlined here tracking purchases, applying costs to sales in reverse order, and calculating COGS and ending inventory you can accurately use the LIFO method.

Though it has advantages like tax savings in inflationary periods, LIFO also has limitations and isn’t accepted worldwide. Consider your industry and regulatory environment before choosing this method. Proper application and record-keeping will ensure your financial reports reflect your business accurately.
