Compound Interest Calculator: How Much Will I Earn?

Compound interest is how your money makes money. Enter the amount you have at the start, such as in your savings account, your interest rate, how long the money will be growing, and how often it compounds, which can range from continuously to annually.

If you are unsure of how often your account or bank will compound interest, ask a bank customer service representative or check your disclosure documents.
