Inflation Purchasing Power

Inflation reduces purchasing power when prices rise. The same nominal amount buys less in the future when inflation compounds over time.

Core formula

Future nominal cost = current cost * (1 + inflation rate) ^ years

Real value = current amount / (1 + inflation rate) ^ years

Answer summary

Use the inflation calculator to compare nominal value and real purchasing power for savings, expenses, and long-term plans.
