Estimate future purchasing power and the amount needed to maintain today’s purchasing power at a fixed inflation rate.
Inflation and purchasing power
When prices rise, the same amount of money generally buys less. This calculator holds the inflation rate constant to compare today’s value with a future scenario.
Future purchasing power = current amount ÷ (1 + inflation)^years Future amount needed = current amount × (1 + inflation)^years
A scenario, not a forecast
Actual inflation changes over time, and a personal basket of housing, food, transport, and healthcare may differ from a national index.
