Frequently asked questions
How does inflation affect my money?
Inflation raises prices over time, so the same amount buys less in the future. This tool compounds your amount at the inflation rate to show its future equivalent cost.
What inflation rate should I use?
It depends on your assumptions and the economy. Many people model a few percent per year; try different rates to see the range. It's an estimate, not a forecast.
Is this financial advice?
No. It's an illustration to help you think about long-term value, not personalized financial advice.
