Compound Interest Explained: Make Your Money Work for You

Compound interest is often called the eighth wonder of the world. Understanding how it works can transform your financial future.

What is Compound Interest?

Compound interest is interest calculated on the initial principal and also on the accumulated interest from previous periods. In simple terms, you earn interest on your interest.

The Power of Compounding

The formula for compound interest is:

A = P(1 + r/n)^(nt)

Where:

- A = Final amount

- P = Principal (initial amount)

- r = Annual interest rate

- n = Compounding frequency per year

- t = Time in years

Example: The Magic of Compounding

Invest $10,000 at 7% annual interest:

- After 10 years: $19,672

- After 20 years: $38,697

- After 30 years: $76,123

The longer you invest, the more dramatic the growth!

Compounding Frequencies

- **Annually**: Interest compounds once per year

- **Quarterly**: Four times per year

- **Monthly**: Twelve times per year

- **Daily**: 365 times per year

More frequent compounding = higher returns (though the difference becomes smaller)

Key Takeaways

3. **Stay Invested**: Don't withdraw during market downturns
