1. What is Compound Interest?

Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. It causes wealth to grow faster than simple interest, especially over long periods.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times \left(1 + \frac{r}{n}\right)^{n \times t} \]

Where:

\( A \) — Final amount
\( P \) — Principal investment amount
\( r \) — Annual interest rate (decimal)
\( n \) — Number of times interest is compounded per year
\( t \) — Time the money is invested for (years)

Explanation: The more frequently interest is compounded, the greater the return, as interest is earned on interest more often.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for savings and investment planning. Small differences in interest rates or compounding frequency can lead to significant differences in returns over time.

4. Using the Calculator

Tips: Enter the principal amount, annual interest rate (as a percentage), number of compounding periods per year (e.g., 12 for monthly), and time in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus accumulated interest.

Q2: How does compounding frequency affect returns?
A: More frequent compounding (daily vs. monthly vs. yearly) results in higher returns because interest is calculated on a growing balance more often.

Q3: What's a typical compounding frequency for savings accounts?
A: Most high-interest savings accounts compound interest daily and pay it monthly.

Q4: How can I maximize compound interest?
A: Start early, contribute regularly, choose accounts with higher interest rates and more frequent compounding, and avoid withdrawing earnings.

Q5: Is compound interest always beneficial?
A: While beneficial for savings, it works against you with debts (like credit cards) where interest compounds on unpaid balances.
