Inflation Calculator
Project how much a current amount would need to grow to maintain the same purchasing power after a selected number of years. The calculation also shows cumulative price growth and the percentage of purchasing power lost at the assumed inflation rate.

Understanding the Inflation Calculator
Review the inputs, outputs, calculation method, and formulas used by this tool.
Understanding the results
- Future equivalent cost
- Amount needed in the future to buy the same goods.
- Cumulative price increase
- Total percentage growth in prices.
- Purchasing-power loss
- Reduction in what one unit of currency can buy.
Calculation principle
Inflation compounds annually, so each year’s price increase applies to the prior year’s higher price level.
- Read and validate the entered values.
- Convert percentages and time periods into compatible units.
- Apply the formulas below and present the calculated results.
Formulas
Future cost
FV = PV × (1 + i)^n
Purchasing-power loss
Loss % = (1 − PV / FV) × 100
Symbols refer to the corresponding input and result labels shown above.
