How this calculator works

Frequently asked questions
Does compounding frequency matter much?
It matters more at higher rates and longer horizons, though the difference between monthly and daily is usually small.
Are returns guaranteed?
No. Investment returns vary and can be negative. This is a projection, not a promise.
Does it account for fees?
No. Subtract expected fees from your annual return for a more realistic figure.
