Calculate the rate of price inflation between two dates using one of our inflation rate calculators.

The Cumulative Inflation Calculator calculates total inflation in percent between exact months and years since 1913. Some calculators do not request a month and instead use an average for the year which would produce similar results to choosing June or July as your month but this would not include inflation for the last half of the year. Although this is fine for long periods of time, for short time periods the result would be much less accurate. Our inflation calculator uses months and years and (unlike most on the web) not only gives the inflation adjusted price but also the total cumulative inflation (see red text in the example below).

But we have several other inflation calculators to choose from.

1) If you want to calculate U.S. inflation from 1774 through future estimates up through 2024 you can use our fun "Steampunk" Calculator. Unfortunately, due to the limitations of the data from years prior to 1913 monthly data isn't available.
