If you feel like $100 disappeared much faster at the grocery store in 2026 than it did a few years ago, the numbers back you up. To see just how much purchasing power has changed, we compared the same mix of common grocery staples using U.S. city-average food price data from the Bureau of Labor Statistics. Rather than comparing today’s prices only with last year, we went all the way back to 2020 and kept the basket itself the same. The result is striking: a representative mix of groceries priced at about $100 using 2020 prices would cost roughly $137 today if its overall increase matched the same BLS-based basket. More importantly, a few products did much more damage to the total than others.
