Monthly US Inflation Rates: 1913-Present

First, a word about this page… it offers monthly rates of inflation in the United States from February 1913 to October 2017. Unless you’re doing some research, there’s a good chance you’re really looking for inflation rates on an annual basis — not per month, since these are the rates that are normally monitored, compared, discussed between economists and reported in the news.

The table below offers a collection of the data published once a month by the US Labor Department’s Bureau of Labor Statistics (www.bls.gov/cpi) after it surveys and analyzes how prices have changed for thousands of goods and services purchased by American consumers. The agency publishes the figures along with its report on the Consumer Price Index (CPI). This data was last updated on November 15, 2017. Actual inflation figures for November become available on December 13, 2017.

Calculating Monthly Inflation Rates

Monthly rates of inflation are calculated using the BLS’s Consumer Price Index (see the data here). To calculate the monthly rate of change for April 2015, as an example, take its CPI of "236.599" and subtract from it the prior month’s March 2015 CPI of "236.119." The result is "0.48." Divide this number by the March 2015 CPI, multiply that by 100, and then add a % sign. The result is April’s monthly inflation rate of 0.2%, as shown in the table above.
