Understanding Compound Interest

Compound interest is when you earn interest on both your original money and on the interest you keep accumulating. It makes your money grow faster over time!

Why It's Powerful:

  • Exponential Growth: Your earnings generate their own earnings
  • Time is Your Friend: The longer you invest, the more dramatic the growth
  • Small Contributions Matter: Regular investments significantly boost results

💡 Pro Tip for US Investors:

Consider tax-advantaged accounts like 401(k)s and IRAs to maximize your compound growth while reducing taxes. Many employers offer matching contributions - that's free money that compounds!
