The latest inflation rate for the United States is -0.2% through the 12 months ended April 2015 as published by the US government on May 22, 2015. The next update is scheduled for release on June 18, 2015 at 8:30 a.m. ET. It will offer the rate of inflation over the 12 months ended May 2015.
The chart, graph and table below displays annual US inflation rates for calendar years 2004-2014. Rates of inflation are calculated using the current Consumer Price Index published monthly by the Bureau of Labor Statistics (BLS). For 2015, the most recent monthly data (12-month based) will be used in the chart and graph.

Since figures below are 12-month periods, look to the December column to find inflation rates by calendar year. These also appear in the graph and chart above. For example, the rate of inflation in 2014 was 0.8%. 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
Annual rates of inflation are calculated using 12-month selections of the BLS’s Consumer Price Index.
For example, to calculate the inflation rate for April 2015, take its CPI of "236.599" and subtract from it last year’s April 2014 CPI of "237.072." The result is "-0.473." Divide this number by the April 2014 CPI and then multiply that by 100 and add a % sign.
The result is April’s annual inflation rate of -0.2%.
