How Compound Interest Builds Wealth
Compound interest is often called the eighth wonder of the world — and for good reason. It's the concept that makes long-term investing so powerful: you earn interest not just on your initial investment, but also on the interest you've already earned.
Here's a simple example: if you invest $10,000 at a 7% annual return and add $200/month, after 30 years you'll have approximately $303,000. But here's the kicker — only $82,000 of that comes from your contributions. The remaining $221,000 is pure compound interest.
The three factors that matter most are: how much you invest, how long you stay invested, and your rate of return. Time is by far the most powerful factor — which is why starting early matters more than starting big.
