Compound interest allows your money to grow exponentially by earning returns on both your initial investment and accumulated interest.

The earlier you start, the more powerful compounding becomes — even small contributions can grow significantly over time.

What Is Compound Interest and Why It Matters

Compound interest is one of the most powerful concepts in finance. It allows your investment to grow exponentially over time because you earn interest not only on your initial deposit but also on the interest accumulated.

The longer your money stays invested, the more it benefits from compounding. Time is the key driver — not just high returns.
