How Compound Interest Works

Compound interest is the process where interest is added to the principal, so that from that moment on, the added interest also earns interest. This addition of interest to the principal is called compounding.

The more frequently compounding occurs and the longer your money remains invested, the greater the compound interest and the higher the potential returns. Even small increases in your interest rate or contribution amount can result in significantly larger returns over time.
