Compound interest is often called the 'eighth wonder of the world.' When you invest money and earn returns, those returns generate their own returns in subsequent periods. Over long time horizons, this creates exponential growth that far exceeds what simple interest would produce. The three key variables are: the amount invested, the rate of return, and time. Of these, time is the most powerful factor — which is why starting early matters more than investing large amounts later.
