The Inflation rate is calculated from the Consumer Price Index (CPI-U) which is compiled by the U.S. Bureau of Labor Statistics and is based upon a 1982-84 Base of 100. Would you like to know the real definition of inflation or how to calculate inflation? or the monthly rather than annual inflation rate? To view the actual Consumer Price Index data that this inflation data is calculated from, go to the Historical CPI table.

Jump to Bottom of InflationTable or click "year" to reverse order. Click "Annual" to sort years by inflation rate rather than date (click again to reverse).Blank Cells indicate that the data is not available because it has not been released by the Bureau of Labor Statistics yet.
A CPI of 195 indicates 95% inflation since 1982*, the commonly quoted inflation rate of say 3% is actually the change in the Consumer Price Index from a year earlier.
The "Annual" on this table is the Average of the individual Inflation rates for that year. Caution, you cannot just add the inflation rates from two consecutive years or even average them to find the total inflation between two dates. If you would like to calculate the inflation rate between two dates you must base your calculations on the actual CPI index or you can use our handy easy to use Inflation calculator or you might prefer to use our Cost of Living Calculator to compare the costs in two cities.
You can find links to Inflation and Consumer Price Index data for other countries HERE. A chart of Inflation by decade, Annual Inflation and Confederate Inflation is also available. Menu navigation is available on every page. We have a complete listing of all of our Articles on inflation, including Inflation Definitions, Which is better High or Low Inflation, and How to Calculate Inflation , Inflation Adjusted Oil Prices (Chart) and Inflation Adjusted Oil Prices (table) and a Monthly Inflation Rate Table.
* Actually the index applies to an average of 1982-1984 so there is no specific date when the index was exactly 100. (If you check the chart here you will see it was somewhere between July and August of 1983. But the reference year is commonly referred to as 1982.)
