How does the Inflation Calculator work?
Inflation is the general rise in prices over time, which means each dollar buys less than it did before.
Adjusted value = amount × CPI(target year) / CPI(start year), using the Bureau of Labor Statistics Consumer Price Index for All Urban Consumers (CPI-U) annual averages.
For example, BLS annual-average CPI-U values show that $100 in 2000 has about $187 of buying power in the latest included year (2025).
The latest included year is 2025. This calculator compares annual averages, not individual months; use the linked BLS series to check the underlying index values.
