In an inflationary environment, which inventory method results in higher gross profit?

In an inflationary environment, the First-In, First-Out (FIFO) inventory method results in higher gross profit because it assumes that the oldest inventory items are sold first. As prices rise, the older inventory costs will be lower than the current market value of the goods sold, leading to higher revenues when those goods are sold. Consequently, the cost of goods sold (COGS) will be lower under FIFO compared to other methods like LIFO (Last-In, First-Out), which assumes that the most recently acquired inventory—most likely at higher costs in an inflationary period—has been sold first. This results in higher gross profit, as the difference between sales revenue and costs is increased.

In contrast, LIFO would report a higher COGS, leading to lower gross profit since it uses the most recently purchased (and more expensive) inventory first. Weighted Average Cost would smooth out the cost differences across the inventory and result in an intermediate gross profit compared to FIFO, while Specific Identification may not apply as broadly, particularly in a general question about inventory methods without specific context about the inventory types. Thus, FIFO is the most advantageous in terms of reporting higher gross profit during times of rising prices.
