Inflation scenario calculator
Compare purchasing power using a user-supplied annual inflation rate.
How to use Inflation scenario calculator
Inflation scenario calculator projects an amount forward using an annual inflation rate you supply, compounded over a chosen number of years. It returns the equivalent future cost of today's amount and what the same amount will be worth in current purchasing power. Rates from -99% to 100% and up to 100 years are accepted, assuming a constant rate.
- Enter the requested values in the settings panel.
- Set current amount, assumed annual inflation (%), years.
- Run inflation scenario calculator, review the output, then use the available copy or download controls.

Limits and processing
Local bounded calculations. Numeric inputs must be finite and within the visible ranges. Lists and tables have operation-specific limits. Models, estimates and supplied rates must be checked against your intended use.
Frequently asked questions
How much will 1000 dollars be worth in 10 years with 3% inflation?
With a constant 3% rate, something costing 1000 today would cost about 1343.92 in 10 years, and 1000 then buys what about 744.09 buys today. The calculator applies (1 + rate) to the power of years.
Can I model deflation in the inflation calculator?
Yes. Enter a negative rate, down to -99%. The equivalent future cost then falls and the purchasing power of the amount rises over the chosen years.
Does the inflation calculator use real historical inflation data?
No. It uses only the single annual rate you enter and applies it every year. Actual inflation varies year to year, so treat the result as a scenario rather than a forecast.
