Frequently Asked Questions
What is compound interest?
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. It makes your money grow faster than simple interest because you earn interest on your interest.
How often is interest compounded?
Interest can be compounded annually, semi-annually, quarterly, monthly, or daily. The more frequently interest compounds, the faster your money grows. Most savings accounts compound daily or monthly.
What is the Rule of 72?
The Rule of 72 is a quick way to estimate how long it takes to double your money. Divide 72 by the annual interest rate to get the approximate number of years. For example, at 8% interest, your money doubles in about 9 years.
