1. What is Compound Interest?

Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. It allows savings to grow faster as interest is earned on interest.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

Where:

• \( A \) — Final amount (ZAR)
• \( P \) — Principal amount (initial investment, ZAR)
• \( R \) — Monthly interest rate (annual rate divided by 12, as a decimal)
• \( N \) — Number of compounding periods (months)

Explanation: The formula accounts for exponential growth of your investment as interest is compounded each month.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for financial planning. It demonstrates how investments grow over time and helps compare different savings or loan options.

4. Using the Calculator

Tips: Enter principal amount in ZAR, annual interest rate in percentage, and investment period in months. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How often does Standard Bank compound interest?
A: Standard Bank typically compounds interest monthly for savings accounts, but terms may vary by product.

Q2: 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 principal plus accumulated interest.

Q3: How does compounding frequency affect returns?
A: More frequent compounding (e.g., monthly vs annually) results in higher returns due to the compounding effect.

Q4: Can I use this for loan calculations?
A: Yes, this formula works for both savings growth and debt accumulation, though loans may have additional fees.

Q5: Are taxes considered in this calculation?
A: No, this calculator shows gross returns. Remember to account for potential taxes on interest income.
