Food Inflation

How It Works

Food inflation in the United States has historically tracked close to overall inflation at 2-3% per year, but several episodes have deviated sharply. The most recent spike began in mid-2021 and peaked at 11.4% year-over-year in August 2022 — the highest rate since 1979. By early 2024, food-at-home inflation had moderated to about 1.2%, though cumulative prices remained 25% higher than pre-pandemic levels. The Cheeseburger Index captures food inflation in a tangible way: the same burger that cost about $2.65 in 2019 costs $3.29 in 2024, a cumulative increase of 24%. Food inflation differs from overall inflation in important ways. Food prices tend to be more volatile because they are affected by weather, disease outbreaks (avian flu devastated egg production in 2022-2023), and geopolitical events (the Ukraine war disrupted grain and fertilizer markets). Food inflation also affects lower-income households disproportionately because they spend a larger share of their income on food — roughly 30-35% for the lowest income quintile versus 8-10% for the highest. The Federal Reserve watches food inflation closely but generally focuses on "core" inflation (excluding food and energy) for monetary policy decisions.
