The Power of Compound Interest

Albert Einstein famously called compound interest the "eighth wonder of the world." It is the concept of earning interest on your interest.

Example

If you invest $10,000 at 7% return:
- Year 1: You earn $700. Total $10,700.
- Year 2: You earn 7% on $10,700 (not just the original $10k). That's $749.
Over 30 years, that $10,000 becomes $76,000 without you adding another penny.
