Enter a dollar amount and two dates. The second date can be later or earlier than the first.

This Historical Inflation Calculator will calculate the amount of CPI price inflation between any two dates from 1913 up to the latest month reported by the U.S. Bureau of Labor Statistics (BLS).

The CPI data is sourced from the BLS. However, we also present our own "Alternate ShadowStats" CPI estimates for comparison purposes.

Further background on the SGS-Alternate CPI series is available in our Public Comment on Inflation Measurement.

Note that we show the Alternate SGS estimates graphically for non-subscribers, and with numerical precision for subscribers.
