Which is better, LIFO or FIFO?

Neither method is universally better; the right choice depends on your tax situation, reporting obligations, and the nature of your inventory.

FIFO (First-In, First-Out) is the more widely used method and works well for most retailers. It assumes the oldest units are sold first, which matches how physical stock actually moves for perishable, seasonal, or fashion goods. During periods of rising costs, FIFO produces lower cost of goods sold, higher reported profit, and a balance sheet inventory value that more closely reflects current replacement cost. That makes FIFO the cleaner choice for businesses seeking financing, attracting investors, or operating under IFRS (where LIFO is prohibited). It is also simpler to audit and explain.

LIFO (Last-In, First-Out) assumes the newest, most expensive units are sold first. In an inflationary environment, that produces higher COGS, lower taxable income, and a real cash-flow benefit. For U.S.-only retailers carrying large volumes of non-perishable or commodity-like goods, such as hardware or bulk building supplies, LIFO can be a legitimate tax strategy. The trade-offs are significant, though: LIFO is banned under IFRS, can leave very old cost layers on the books at outdated values, and tends to make the balance sheet harder to interpret.

A useful way to think about it:

  • Choose FIFO if you want a cleaner balance sheet, simpler reporting, and global compatibility.
  • Consider LIFO only if you are a U.S.-only business under sustained cost inflation and the tax savings outweigh the reporting complexity.
