FAQ

Common questions

How is compound interest calculated?

This estimate compounds monthly by applying the periodic rate to the balance and then adding the monthly contribution.

What changes the final value most?

Time, contribution amount, rate of return, fees, taxes, and consistency can all change the final value.

Why can small rate changes matter?

A higher or lower rate affects each compounding period, so the effect can grow over longer time horizons.
