What CPI data does this calculator use?

This tool uses annual US Consumer Price Index (CPI-U) data from the Bureau of Labor Statistics (BLS), covering 1913 through 2025, with the exact values BLS publishes (one decimal before 2007, three decimals from 2007). The CPI-U measures the average change in prices paid by urban consumers for a representative basket of goods and services.

How is the inflation-adjusted value calculated?

The formula is: Adjusted Value = Original Amount × (CPI in Target Year / CPI in Base Year). This gives you the equivalent purchasing power in the target year's dollars.

Why does the result show more money when converting from past to present?

Because of inflation, prices generally rise over time, so you need more dollars in later years to buy the same goods. $100 in 1950 required far fewer dollars than the same basket of goods costs today.

Can I calculate backwards (present to past)?

Yes. Set the starting year to a recent year and the ending year to an earlier one. The result will show a smaller number, reflecting that the same goods cost less in past dollars.

How accurate is this calculator?

The calculator uses official BLS annual CPI-U averages, which are widely accepted for inflation adjustments. Keep in mind that individual spending patterns vary — personal inflation rates may differ from the CPI average.

What years are supported?

This tool covers 1913, the first year in the BLS CPI-U series, through 2025, the latest full-year average. The 2026 average will be added after BLS publishes the December 2026 index in January 2027.

Can I download the CPI data?

Yes. The table below the calculator lists every annual average from 1913 to 2025 with the change from the prior year and the value of $1 in 2025 dollars. Download it as CSV; it is free to reuse under CC BY 4.0 with a link to this page.

Why is October 2025 missing from BLS monthly data?

BLS did not publish an October 2025 CPI-U index; the monthly series shows no value for that month. The 2025 annual average used here is the figure BLS published for the year.

What was the inflation rate in 2025?

The CPI-U annual average rose 2.6% from 2024 to 2025, from 313.689 to 321.943. Monthly year-over-year rates moved around that figure during the year.

Why does my result differ from the BLS calculator?

The BLS CPI Inflation Calculator compares single months, while this tool compares annual averages. Picking January 2000 to January 2025 there gives a slightly different answer than 2000 to 2025 here.

Percent change is computed from the published annual averages and rounded to 0.1. It can differ slightly from December-to-December inflation, which BLS reports separately. BLS did not publish an October 2025 index.

Quick answer

Inflation-adjusted value = amount × (CPI in the later year ÷ CPI in the earlier year). With BLS CPI-U annual averages, $100 in 2000 buys what $186.96 buys in 2025, because the index rose from 172.2 to 321.943.

Examples

$100 in	Equals in 2025 dollars
1913	$3,251.95
1950	$1,335.86
1970	$829.75
1980	$390.71
2000	$186.96
2010	$147.64
