In accounting, FIFO (First-In, First-Out) is an inventory costing method assuming the oldest, first-purchased goods are the first ones sold, impacting financial statements by matching older, often lower costs to current revenues, resulting in higher reported profits during inflation, and keeping the balance sheet's ending inventory valued at more recent, higher costs. It's widely used for perishables (food, pharma) or fashion, aligning well with physical inventory flow and accepted under GAAP and IFRS.
