Only goes back to 1913 – Price Inflation Review

Some calculators aren't current enough-they may stop at 2011, for example but this one doesn't go far enough back in time. The data exists but maybe not in the particular database used. There are plenty of inflation calculator apps as well as online available with a longer period of time, going back to the early 1800s. This has averages so what it does have may be more useful than some others if you're looking for quarterly averages.
