Updated Cumulative Inflation Calculator

Published on February 5, 2026 Updated on February 13, 2026 by Tim McMahon Leave a Comment

We've updated and modernized our Cumulative Inflation Calculator. We've made it faster and fixed the bugs. It will calculate the total cumulative inflation from any month since January 1913 to any other month up to the most recent CPI release. It will also tell you how much your starting amount would be after experiencing that amount of inflation. We've also updated our "How much would it cost calculator," and added an estimated flat rate inflation calculator both forward and backward. So now you can calculate backward from the current price to estimate how much it would have cost "X" years ago. Check Out our New Updated Calculators Here! … [Read more...]

Long Term U.S. Inflation

Published on April 29, 2013 by Tim McMahon Leave a Comment

We have updated the charts on long Term Inflation, including Average Annual Inflation by decade, Cumulative Inflation by Decade and Cumulative Inflation since 1913. The Chart below shows the Annual Inflation Rates for each decade. Each bar represents the average Annual Inflation for that decade (not the total cumulative inflation for that 10 year period but how much it increased each year on average during that decade).   Do you know: 1) Average Annual Inflation since 1913: 2) That deflation in the "Roaring 20's" was almost as bad as in the "Great Depression" of the 1930's? 3) How Crop Subsidies affected farm prices in the 1920's and 30's? 4) How the proliferation of … [Read more...]
