FAQ

Frequently asked questions

What inflation rate should I use?

The historical US average has been roughly 3% annually over long periods, though it varies significantly year to year.

How does inflation affect savings?

If your savings earn less than the inflation rate, their real purchasing power declines over time even as the nominal balance grows.

Is inflation the same everywhere?

No — inflation rates differ by country and by category of goods and services (e.g. healthcare vs. electronics).
