Use our inflation calculator to see how the buying power of the US dollar has changed over time.
The inflation calculator uses the latest CPI (Consumer Price Index) data published by the U.S. Bureau of Labor Statistics. We use the average CPI for a year or the most recent monthly CPI when the current year is selected.
How to Calculate a Price Adjusted for Inflation?
Let’s say you want to know how much stuff you could buy with $15 back in April 1925.
To find out, you first need to look up the CPI for both months. See the chart below for all CPI historical data.
🤔 CPI is a measure of purchasing power of the US dollar reported by the U.S. Bureau of Labor Statistics. It examines the average price of a hypothetical basket of goods and services purchased by everyday consumers in order to evaluate changes in expenses associated with the cost of living.
Once you look up those two numbers you’ll find:
CPI in April 1925: 17.2 CPI in October 2020: 260.388
You can then use the following formula to calculate the price:
October 2020 Price x (October 2020 CPI / April 1925 CPI) = April 1925 Price
Or, using actuall numbers:
$15 x (260.388 / 17.2) = $227.08
