FIFO Explained: Meaning, Types, Process, and Use Cases
FIFO, or First-In, First-Out, is one of the most important inventory costing methods in accounting and financial reporting. It determines which inventory costs move into cost of goods sold first and which remain on the balance sheet, so it directly affects profit, taxes, margins, working capital, and financial analysis. In plain terms, FIFO treats the oldest inventory costs as leaving first and the newest costs as staying in stock.
