Inflation Calculator
Using the US Consumer Price Index, $100 in 2000 buys what $182.17 buys in 2024, a total rise of 82.2% or 2.5% a year. Going back further, $1 in 1913 equals about $31.69 in 2024.
How to use
- Enter a dollar amount.
- Choose the year the amount is from and the year you want it in. The swap button flips the two years.
- Read the equivalent amount, the total inflation between the two years and the average rate per year.
How it works
Equivalent amount = amount x (CPI of the later year / CPI of the earlier year). The CPI used is the CPI-U (all items, US city average, not seasonally adjusted, 1982-84 = 100) annual average published by the US Bureau of Labor Statistics, series CUUR0000SA0.
Total inflation = CPI ratio - 1. The average yearly rate is the compound rate that gives the same total: ratio^(1 / years) - 1. For going back in time the tool divides instead of multiplying, so the amount shrinks, and the yearly rate stays the same as in the forward direction.
Years are whole calendar years averaged over all months. It cannot tell you the value in a particular month. It also measures a basket of typical urban consumer goods, so your personal inflation may differ, for example if you spend more on housing, health care or tuition.

- US Bureau of Labor Statistics, Consumer Price Index, CPI-U all items, U.S. city average, not seasonally adjusted (CUUR0000SA0). See bls.gov/cpi.
- The table is updated once a year, in January, when BLS publishes the December CPI and the previous year's annual average becomes final.
- The CPI covers urban consumers and is the index most used to adjust US dollar amounts for inflation. For wage or pension adjustments check which index your contract names (CPI-W, for example).

FAQ
Where does the data come from?
The Bureau of Labor Statistics CPI-U, all items, annual average (series CUUR0000SA0). Data for 1913 through 2024 is the published annual average. The values were retrieved on 2026-10-13 and cross-checked against a second published table.
Why are 2025 and 2026 marked?
October 2025 prices were never collected because of the federal funding lapse, so the 2025 figure here is the average of the 11 months that exist, not an official BLS annual average. 2026 is the average of the months published so far (through August 2026) and will change as the year ends.
Does this work for currencies other than US dollars?
No. It only uses US prices. For another country you need that country's own consumer price index.
Why is the answer different from other inflation calculators?
Many calculators use December-to-December or month-to-month CPI, or a different year's base. This one compares annual averages, so a year-end price level can differ from it.
Is my data sent anywhere?
No. The price table is built into the page and the calculation runs in your browser.
