Compound interest is the principle of earning interest not only on your initial investment, but also on the interest that accumulates over time. It's one of the most powerful forces in long-term wealth building.
When you invest money, you typically earn interest (or returns) over time. With compounding, those returns are reinvested - meaning you start earning “interest on your interest.” Over time, this leads to exponential growth.
The longer you stay invested, the more powerful compounding becomes. Even small, consistent contributions can grow significantly if left to compound over many years.

Notice how the growth accelerates over time - that’s compounding in action. Starting early can make a huge difference, even if the amount is small.
