Interview Questions for Warehouse Optimization and Logistics Management

FIFO (First-In, First-Out) and LIFO (Last-In, First-Out) are two fundamental inventory management methods that dictate the order in which items are sold or used. They significantly impact the cost of goods sold (COGS) and the value of ending inventory on your balance sheet.

FIFO: Imagine a bakery. The first loaves of bread baked are the first ones sold. This is FIFO. The oldest items are used or sold first. In accounting, this leads to a COGS calculation reflecting the cost of the oldest inventory. During inflationary periods, FIFO results in lower COGS and higher net income because older, cheaper items are sold first.

LIFO: Now imagine a stack of pallets. With LIFO, you’re always using the top pallet – the newest arrival. The last items received are the first ones used or sold. This method, generally permitted only under US GAAP, results in a COGS reflecting the cost of the newest inventory. During inflation, this means higher COGS and lower net income.

The Key Difference: The core difference lies in the order of inventory usage and its impact on financial statements. FIFO is more intuitive and often preferred for perishable goods, while LIFO can be beneficial in tax optimization during periods of inflation (though it can distort the true picture of profitability).
