Frequently asked questions

How does compound interest work?

Each period your balance earns a return, and that return then earns a return of its own. Over long horizons the growth on past growth comes to outweigh what you contributed.

What return should I assume?

Long-run share market averages have sat around 7–10% a year before inflation, but real returns vary a lot year to year. Treat any single figure as a shape, not a promise.

Is this calculator free?
