How it works
A dollar has a timeline.
The calculator applies the same annual inflation assumption once per year. It is a way to make purchasing-power changes easier to see, not a forecast of future prices.
Inflation differs by category, location, and time. Use the rate as a scenario rather than a promise about future prices.
Common questions
Before you use the number.
How does the inflation calculation work?
The future cost is the amount today multiplied by one plus the annual inflation rate, raised to the number of years.
Does this predict the price of a specific item?
No. It applies one broad annual rate. A specific item can rise faster or slower than the assumption.
