How it works
- The calculator assumes a constant annual inflation rate.
- Future equivalent cost estimates how much money may be needed in the future to purchase something that costs the starting amount today.
- Purchasing power shows how much of today's value the same nominal amount would represent after inflation.
Future Equivalent Cost = Current Amount × (1 + Inflation Rate)^Years
Future Purchasing Power = Current Amount / (1 + Inflation Rate)^Years
Frequently asked questions
What does inflation do to purchasing power?
When prices rise, the same nominal amount of money generally buys fewer goods and services.
Is the inflation rate constant in real life?
No. Actual inflation changes over time. The calculator uses the rate you enter as a simplified planning assumption.
Can I change the 10-year projection?
Yes. Ten years is the default display period and can be changed.
Disclaimer
This calculator uses a constant inflation assumption for general educational and planning purposes. Actual inflation varies over time and across countries, products, services, and individual spending patterns.
