What This Shows:

More than half of your final wealth comes from interest, not your own contributions. That’s the power of compounding over time.

Compound interest is the foundation of long-term wealth creation. It allows your money to grow exponentially rather than linearly.

Why it matters:

• Reduces pressure of saving large amounts later

The earlier you start investing, the greater your results.
