A dollar is not a fixed unit of value — it is a unit whose value drifts every year, and over decades the drift compounds into transformation. This calculator converts any amount between any two years from 1913 to the present using historical US Consumer Price Index (CPI-U) averages: the same method government agencies, economists and courts use to compare money across time.
The classic uses: translating a 1975 salary or house price into today's terms, checking whether your own pay has kept up with inflation since you started working, understanding what a 'million dollars' meant in a movie from 1990, or seeing why cash savings need a return just to stand still. Every calculation happens in your browser against an embedded CPI table — no lookups, no tracking.
