Inflation Calculator
A dollar used to stretch further. See exactly how much further.
CPI-U table is approximate (2010 ≈ 218, 2015 ≈ 237, 2020 ≈ 259, 2024 ≈ 314, 2026 ≈ 325). Years before 2010 are not covered.
Estimates only — not financial advice. CPI values are approximate; 2026 is a partial-year estimate.
How to convert dollars across years
- Enter the dollar amount you want to convert — e.g. the price of a car in 2010.
- Pick the from-year and to-year (both must be 2010–2026).
- Press Calculate. You'll see the inflation-adjusted value, the cumulative price change, and the average annual inflation rate between the two years.
- Reverse it by swapping the years — the same math converts modern dollars back into past-year purchasing power.
Frequently asked questions
How do I calculate inflation between two years?
Divide the later year's CPI by the earlier year's CPI and multiply your dollar amount by that ratio. This calculator does it for 2010–2026 in one click.
What is CPI-U?
The Consumer Price Index for All Urban Consumers — the Bureau of Labor Statistics' headline measure of US inflation, tracking a broad basket of goods and services.
Why aren't years before 2010 included?
This tool ships a compact built-in table covering 2010–2026. For pre-2010 conversions, use the Bureau of Labor Statistics' full CPI series.
What does the average annual rate mean?
It's the steady yearly rate that would compound to the same total price change — the geometric mean, not the average of each year's individual rate.
Is this financial advice?
No. Planning estimates only — the built-in CPI values are approximate.
