What is compound interest?
Compound interest is calculated on the starting balance and on interest already added to that balance. This calculator estimates future value from an initial deposit, a fixed nominal annual rate, a selected compounding frequency, and a time period.
What is not included?
This estimate assumes the rate stays the same and there are no additional contributions, withdrawals, taxes, or fees. Real account returns are not guaranteed and may differ. This tool is for general education, not investment advice.
