What is Inflation?
Inflation is the rate at which the general level of prices for goods and services rises, eroding the purchasing power of currency over time. When inflation rises, each dollar buys fewer goods and services. The Consumer Price Index (CPI) published by the Bureau of Labor Statistics measures the average change in prices paid by urban consumers for a market basket of goods and services.
How This Calculator Works
This calculator uses the CPI-U (Consumer Price Index for All Urban Consumers) to calculate how the value of the US Dollar has changed between any two years from 1913 to 2026. The formula is: Adjusted Value = Original Value x (CPI in target year / CPI in original year).
