About Compound Interest

Compound interest is the addition of interest to the principal sum of a loan or deposit. In other words, it's interest on interest. This calculator assumes that contributions are made at the beginning of each month and interest is compounded at the frequency you select. The actual returns may vary based on market conditions and fees. This is for educational purposes only and should not be considered as financial advice.
