Understanding Compound Interest
Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It’s often called “interest on interest” and can cause wealth to grow exponentially over time.
The power of compounding: With regular contributions, your money grows at an accelerating rate because you earn interest on a larger balance each period. Even small, regular investments can grow into substantial sums over long periods.
Key factors affecting growth:
- Time: The longer your investment period, the more dramatic the compounding effect
- Rate of return: Higher interest rates significantly accelerate growth
- Contribution frequency: Regular investments boost the compounding effect
- Tax efficiency: Taxes reduce your effective return rate
Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn’t, pays it.
– Albert Einstein
