How to Use The CPI Inflation Calculator?

For example, if you would like to know the difference between the value of $1 in 2014 versus $1 in 1945, type 1 in the “costing” field, type 1945 in the first year field, and 2014 in the second one. Hitting “Calculate” will display the result and generate a new chart.

How Does This Calculator Work Exactly?

As mentioned above, this inflation calculator uses the CPI (Consumer Price Index) rates from the Bureau of Labor Statistics. Rates are available from 1913 to 2014. New rates are published every month on the BLS website and are available publicly. Our calculator’s script extracts the rates for the selected dates and instantly calculates the result.

What is The Link Between CPI and Inflation?

The CPI is used by government agencies, banks and different entities to measure the effectiveness of fiscal and monetary policy, and to determine when that policy needs to be adjusted. The CPI basically correlates with purchasing power. When you hear the terms ‘in today’s dollars,’ or ‘adjusted for inflation,’ the values discussed have been adjusted by using the CPI in order to reflect true purchasing power, or the amount a dollar will buy, at different times in history.
