About this episode

Compound interest is the single most powerful force in personal finance — yet almost nobody learns about it in school. In this episode Mike breaks it down from the ground up so you can finally understand what all the fuss is about.

What is compound interest?

Simple interest is earning interest on your original amount. Compound interest is earning interest on your interest. That one difference, over time, creates a snowball effect that is almost impossible to believe until you see the numbers.

The snowball effect

Imagine rolling a small snowball down a very long hill. At first it barely grows. But as it picks up more snow, it starts to grow faster and faster. That's compound interest — slow at the start, then almost unstoppable over time.

Why starting early is everything

The most important variable in compound interest isn't how much you invest — it's time. Starting 10 years earlier can literally double or triple your final wealth, even if you invest the same total amount. Mike walks through the exact numbers so you can see it for yourself.
