The Power of Compound Interest
Compound interest is often called the "eighth wonder of the world" because of its powerful ability to grow wealth over time. Unlike simple interest, which is calculated only on the principal, compound interest is calculated on both the principal and accumulated interest.
Tips for Maximizing Your Returns
- Start investing as early as possible
- Make consistent monthly contributions
- Choose more frequent compounding when possible
- Reinvest your earnings rather than withdrawing them
