Note: 2026 uses a January–September partial-year average of CPI-U (BLS), not a full-year figure. Data through September 2026; the latest single-month index is 336.940. 2025 values are annual averages pending the BLS annual confirmation.
About this calculation
Here's the short answer: $100 in 2020 buys what roughly $128.00 buys today — prices have multiplied about 1.28× since then. 2020 was the COVID-19 pandemic year. On the price side, inflation briefly turned negative in the spring as demand collapsed — the only deflation since 1955, and nobody enjoyed how it happened. Context like this matters because inflation was never an even tide — some years barely moved prices, and others (ask anyone who bought a house in 1980) reset them violently. The math itself is simple: the Consumer Price Index for All Urban Consumers (CPI-U), published by the Bureau of Labor Statistics, stood at a certain level in 2020 and stands higher today, and the ratio between the two is your conversion. The reason the cumulative number always surprises people is that inflation compounds like interest — each year's increase builds on the last one, and the curve steepens even when the annual rate looks tame. Try a few year pairs in the calculator above; the gap between what your grandparents paid and what you pay is usually bigger than intuition suggests.
