About "Inflation Rate Since a Given Year" Calculator
Pick a year and this page tells you how far prices have moved since — the total rise, the average yearly rate, and what a single dollar from that year is worth in today's money.
Enter a year: anything from 1913 to 2025.
Read the result: cumulative inflation since that year, the average annual rate behind it, and the value of one of that year's dollars today.
Since 1940, prices have risen 2,285.13% — that is 86 years at an average of 3.76% a year. One 1940 dollar buys what $23.85 buys today; put the other way round, a dollar today would have been worth about $0.04 back then.
The source is the Consumer Price Index for All Urban Consumers (CPI-U) from the U.S. Bureau of Labor Statistics. Each past year is the annual average BLS publishes for it, and today is the latest published month, July 2026. The answer moves when BLS publishes, not when the clock does.
Averages hide a lot. An average of 3.76% across 86 years does not mean prices rose by that much in any particular year: the span contains years well above it and years where prices fell.
