How to use the inflation calculator
Select whether you want to estimate a future price from an amount today or convert a future amount to its estimated purchasing power today. Enter the amount, an average annual inflation rate, and the number of years. The estimate updates when you select Calculate.
How inflation changes purchasing power
Inflation describes a general rise in prices over time. When prices rise, the same amount of money usually buys fewer goods and services. This calculator applies one constant annual rate, compounded once per year, for the period you enter.
View the calculation formula
Future amount = starting amount × (1 + annual inflation rate)number of years. Estimated value today = future amount ÷ (1 + annual inflation rate)number of years. The calculator uses the same formula in reverse for the purchasing-power estimate.
Questions and limitations
Is this an official inflation forecast?
No. It is a mathematical estimate using the constant rate you provide. Actual inflation changes over time and differs by country, product, and household spending.
Where can I get an inflation rate?
Use a credible official statistics agency or central bank for historical consumer price index information in your country. This calculator does not retrieve or verify external rates.
Does the currency selector convert money?
No. It changes how amounts are displayed. It does not convert exchange rates or account for country-specific inflation.
