The inflation calculator uses U.S. government provided Consumer Price Index (CPI) data to measure the purchasing power of the dollar over time. It’ll provide a look into the present, past or any time between. (Consumer inflation climbed 3.8% over the past year. It increased 0.4% in August. The next U.S. government update is on October 19, 2011.)
Inflation Calculator: Money’s Real Worth Over Time
How to use: You can start with any date from 1913 through 2011. The first date field can also begin in the present, like 2011, and then move backwards – each method is interesting. The inflation calculator starts with default values just to give a quick glimpse into how it works. Simply clear or edit the numbers with your own.
