Table: Annual Inflation Rates by Month and Year
Since figures below are 12-month periods, look to the December column to find inflation rates by calendar year. For example, the rate of inflation in 2018 was 1.9%.
The last column, “Ave,” shows the average inflation rate for each year. They are published by the BLS but are rarely discussed in news media, taking a back seat to a calendar year’s actual rate of inflation.
Calculating Annual Inflation Rates
For example, to calculate the inflation rate for January 2017, subtract the January 2016 CPI of "236.916" from the January 2017 CPI of "242.839." The result is "5.923." Divide this number by the January 2016 CPI and then multiply by 100 and add a % sign.
The result is January’s annual inflation rate of 2.5%.
