Compound Interest Growth

How Compound Growth Works

Compound interest is often called the “eighth wonder of the world” for a reason — your money earns interest on both your original investment and the interest it already earned. This creates exponential growth over time, especially when you contribute regularly.

Using the Investment Calculator

This calculator assumes monthly compounding and helps you visualize the long-term impact of consistency. The earlier you start, the more time your money has to multiply — even modest investments can grow significantly with time and patience.
