LIFO (Last-In, First-Out) is an inventory valuation method where the most recently purchased items are the first to be sold. In construction equipment management, this method impacts cost of goods sold (COGS) and taxable income. Learn how LIFO accounting can help reduce taxes during inflation and improve financial reporting strategies.


LIFO is an inventory accounting method where the newest stock is expensed first, matching current costs against current revenue.
LIFO, short for Last-In, First-Out, is an accounting approach where the most recently purchased inventory is expensed first when calculating the cost of goods sold (COGS).
This means that newer stock is recorded as an expense, while older inventory remains on the balance sheet at its original, often lower, cost.
The LIFO method plays a significant role in determining taxable income and the valuation of remaining inventory, particularly in fluctuating price environments.
LIFO stands in contrast to FIFO (First-In, First-Out), which assumes that the oldest inventory is sold first.
LIFO accounting can result in lower profits and reduced tax liabilities during inflationary periods, as newer, higher-cost items are accounted for in COGS.
Many companies use LIFO when prices are rising, allowing them to record a higher COGS and thus lower their taxable income.
Some industries, such as retail or food services, rely on LIFO accounting to ensure that their newer goods are sold first, matching customer demand for fresh products.
Using LIFO also impacts financial statements by lowering inventory values, which affects profit margins.

The mechanics of LIFO are fairly straightforward:
Modern software solutions like Clue extend LIFO principles to construction equipment management:
| Date | Equipment Purchased | Units | Price Per Unit | Total Cost |
|---|---|---|---|---|
| Nov 1 | Hydraulic Excavator | 5 | $30,000 | $150,000 |
| Nov 15 | Skid-Steer Loader | 5 | $32,000 | $160,000 |
| Dec 1 | Heavy-Duty Bulldozer | 5 | $34,000 | $170,000 |
| Units Sold | Unit Price | Total Cost |
|---|---|---|
| 5 | $34,000 | $170,000 |
| 5 | $32,000 | $160,000 |
| Total COGS | $330,000 | |
LIFO uses the latest purchase price for COGS, resulting in tax savings and lower reported income.
Businesses that deal with rising inventory costs often adopt LIFO accounting. Supermarkets and pharmacies prefer LIFO since most of their products are subject to inflation. Similarly, convenience stores, especially those selling fuel and tobacco, use LIFO to account for the long-term increase in costs for these goods.
In construction, LIFO (Last In, First Out) refers to a process where the most recently added item is the first to be used or removed. For example, when materials are stacked at a construction site, the last items placed on top are the first ones to be taken for use in the project. This method ensures that the newest materials are utilized before older stock, helping manage inventory efficiently and reducing waste.
