What is FIFO / LIFO?

First In, First Out / Last In, First Out

Quick Answer

FIFO stands for 'First In, First Out' and LIFO stands for 'Last In, First Out.' These are methods used in accounting to manage inventory and determine the cost of goods sold.

Overview

FIFO and LIFO are two inventory valuation methods used by businesses to track their stock. FIFO means that the oldest inventory items are sold first, while LIFO means the newest items are sold first. This choice affects how a company reports its profits and taxes, as the cost of goods sold can vary significantly between these methods. In practice, if a bakery uses FIFO, it would sell its oldest bread first, ensuring that customers receive fresh products. Conversely, if it uses LIFO, the bakery might sell its newest bread first, which could be beneficial if prices are rising. The method a company chooses can impact its financial statements, tax liabilities, and cash flow, making it a crucial decision in accounting. Understanding FIFO and LIFO is essential for investors and business owners because it affects how a company's profitability is perceived. For example, during periods of inflation, LIFO can result in lower taxable income since it matches higher costs with current revenues. This can lead to cash flow advantages, but it might also present a less favorable view of inventory levels on the balance sheet.
