How this works
This tool compounds an assumed average annual inflation rate over the number of years between your two dates, to estimate how much purchasing power has changed. The default 3% reflects a commonly cited long-run US average, but actual year-to-year inflation varies significantly.
Is this based on official CPI data?
No - this uses a single assumed average rate you can adjust, rather than pulling actual historical CPI data year by year, so treat the result as a rough estimate rather than a precise historical figure.
