- $100 in 2021 is worth $118.81 in 2025 on the BLS CPI-U index — a total price increase of 18.8% over 4 years. The calculation is $100 × index(2025) ÷ index(2021) = $100 × 321.9 ÷ 271.0.
- What was the average inflation rate from 2021 to 2025?
- US consumer prices rose about 4.4% per year on average between 2021 and 2025, compounding to a total increase of 18.8%. This is the annualised change in the BLS CPI-U annual-average index (all items, 1982-84=100).
- Why has the dollar lost value since 2021?
- Because of sustained inflation: when average prices rise year after year, each dollar buys fewer goods and services. To match the buying power of $1 in 2021 you would need $1.19 in 2025. Inflation since 2021 reflects the cumulative change in the BLS CPI-U, the U.S. headline price index.
