LIFO (Last-In, First-Out) and FIFO (First-In, First-Out) are two commonly used inventory valuation methods. They differ in how they assign costs to inventory and calculate the cost of goods sold (COGS):
LIFO: Under the LIFO method, it is assumed that the most recently purchased or produced inventory is sold first, and the cost of goods sold is based on the latest costs incurred. This means that the cost of inventory recorded on the balance sheet represents the older, lower-priced inventory. During periods of rising prices, LIFO results in higher COGS, lower net income, and lower ending inventory value compared to FIFO. LIFO is often favored in times of inflation as it can have tax advantages due to lower reported income and lower taxable income.
FIFO: Conversely, under the FIFO method, it is assumed that the oldest inventory is sold first, and the cost of goods sold is based on the earliest costs incurred. This means that the cost of inventory recorded on the balance sheet represents the newer, higher-priced inventory. In periods of rising prices, FIFO results in lower COGS, higher net income, and higher ending inventory value compared to LIFO. FIFO provides a more accurate representation of current inventory costs, but it can result in higher income taxes during inflationary periods.
The choice between LIFO and FIFO depends on factors such as industry practices, tax implications, and the company’s specific objectives. LIFO may be preferred in industries with rapidly changing prices, while FIFO may be more suitable for companies seeking to match costs with revenues accurately.
