How Compound Interest Actually Works

Key Insights

What is compound interest, really? It’s the process where interest earned on your money doesn’t just sit idle—each period, that interest adds to your principal, so the next round of interest is calculated on a larger total.

For example, saving $500 at a 5% annual rate:

• Year 1: Earns $25 → Total: $525
• Year 2: Earns 5% on $525 → $26.25 → Total: $551.25
• Year 3: Earns 5% on $551.25 → $27.56, finishing with $578.81

Although the interest per period is only slightly more over time, the growing base eventually accelerates growth significantly—doubling your money in just 14 years at this rate. This simple rule reveals that patience and consistency unlock exponential returns beyond initial expectations.
