How Compound Interest Works

Compound interest is often called the “eighth wonder of the world” because it helps investments grow exponentially over time. Instead of earning interest only on your starting balance, you also earn interest on the accumulated interest from previous periods.

Example:

If you invest $1,000 at a 10% annual interest rate, your money grows every year based on the new balance — not just the original amount. Over time, this creates powerful long-term growth.
