Why Is Understanding Compound Interest Important?
Compound interest is one of the most powerful concepts in finance. Unlike simple interest, which is only calculated on the principal, compound interest is calculated on the principal and the accumulated interest.
- Accelerated Growth: Your money grows faster because you earn returns on your returns, creating a snowball effect over the long term.
- Achieve Goals Faster: The more frequently interest compounds (e.g., monthly vs. annually), the quicker your investment grows, helping you reach your financial milestones sooner.
- Smart Investment Decisions: By comparing how different interest rates and compounding frequencies affect your savings, you can make more informed choices about where to put your money

Frequently Asked Questions (FAQ)
- What is the “power of compounding”?
It refers to the ability of an investment to generate earnings, which are then reinvested to generate their own earnings. It’s the concept of earning “interest on interest,” which leads to exponential growth over time. - What’s the difference between simple and compound interest?
Simple interest is calculated only on the initial principal amount. Compound interest is calculated on the principal plus any interest that has already been earned, leading to much faster growth. - How does compounding frequency affect my returns?
The more often interest is compounded, the higher your returns will be. For example, an investment with interest compounded daily will grow faster than one compounded annually, even at the same interest rate.
