Frequently asked questions

What does compounding frequency mean?

It is how many times per year interest is added to the balance.

Are contributions included?

Yes. Enter an optional contribution made at the end of each compounding period.

Does the estimate include fees or taxes?

No. It is a mathematical estimate before fees, tax, inflation, or changing rates.

Can the interest rate be zero?

Yes. The result then reflects the initial amount plus contributions.

Is this financial advice?

No. It is an estimate, not a promise of investment performance.
