Assumptions and formula
Past amounts are adjusted with the Consumer Price Index for All Urban Consumers (CPI-U), U.S. city average, all items, published by the Bureau of Labor Statistics: equivalent value = amount × CPI of the later year ÷ CPI of the earlier year. Each year uses its annual average CPI; 2026 uses the latest month published, August 2026 (334.980).
Average yearly inflation is the compound rate between the two years: (CPI later ÷ CPI earlier) to the power 1 ÷ years, less 1. The keep-up comparison divides the amount now by the inflation-adjusted amount. Future mode grows today’s amount at the rate you enter each year. BLS published no index for October 2025 because of the 2025 lapse in appropriations; the annual averages used here are BLS’s own.
Worked example
$100 in 2000 is $194.53 in August 2026: prices up 94.5%, 2.59% a year, so $100 today buys what $51.41 bought in 2000. A $50,000 salary in 2016 is $69,785 in today’s dollars, so $60,000 now is 14% less in real terms. At 3% a year, $100 of today’s spending costs $134.39 in 10 years.
Frequently asked questions
How much is $100 from 2000 worth today?
$194.53 in August 2026 dollars, with the official CPI-U: prices have risen 94.5% since 2000, 2.59% a year on average. Put the other way, $100 today buys what $51.41 bought in 2000.
What is the inflation rate now?
3.4% over the 12 months to August 2026 (CPI-U, not seasonally adjusted, 334.980 against 323.976 a year earlier). Inflation in 2025 as a whole, annual average on annual average, was 2.6%.
How is an inflation-adjusted value calculated?
Multiply the amount by the CPI of the later year and divide by the CPI of the earlier year. $1 in 1913, when the CPI averaged 9.9, is $33.84 at August 2026’s 334.980.
Has my salary kept up with inflation?
Enter your salary then, the year, and your salary now. $50,000 in 2016 is $69,785 in August 2026 dollars, so a salary of $60,000 today is 14% lower in real terms despite the $10,000 raise.
How much will things cost in the future?
Choose “future” and enter a rate. At 3% a year, what costs $100 today costs $134.39 in 10 years, and $100 then will buy what $74.41 buys now.
