Inflation adjuster
Estimate what an amount in one year is worth in another year, assuming a constant average annual inflation rate. Runs entirely offline in your browser.
How it works. Adjusted ≈ Amount × (1 + rate/100)(to − from).
You can project forward or backward by swapping years. For historical accuracy, use year-by-year official index ratios from
BLS CPI or
ONS
instead of a single average rate.
Example defaults
Defaults ($100 from 2000 to 2024 at 2.5%) are illustrative. They are not a claim about actual US or UK inflation over that span.
