Ultimate Guide to Compound Interest

Unlock the secrets of exponential growth and learn how compound interest can transform your finances.

What is Compound Interest?

Compound interest means you earn interest not just on your original money, but also on the interest that money earns. Over time, this leads to exponential growth of your investment or savings. The more often interest is compounded, the more you earn.

Example: If you invest $1,000 at an annual interest rate of 5% compounded yearly, after 10 years you would have $1,629, not just $1,500 as with simple interest.
