Scenarios, not forecasts
No one — including this site — knows future inflation. Unlike some calculators, we do not dress up a single assumed rate as a prediction, and we never mix forecast values into historical data. For the historical side of the story, use the value of money calculator, which works only with published CPI data. The long-run U.S. average over the last 30 years is 2.5% per year; over the full span since 1913 it is higher, because it includes the 1970s.
