Compound Interest: The 8th Wonder of the World

Compound interest is earning interest on your interest. Over time, this creates exponential growth that can turn modest savings into life-changing wealth.

The Simple Math

If you invest $10,000 at 10% annually: after 10 years you have $25,937. After 30 years? $174,494. That's the power of doing nothing but waiting.

Start as Early as Possible

Time is the most important variable. Someone who invests $5,000/year from age 25–35 (10 years only) ends up with MORE at 65 than someone who invests $5,000/year from 35–65 (30 years). The 10-year head start wins.
