1. What is Compound Interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods. It allows savings to grow at a faster rate compared to simple interest, making it a powerful tool for long-term wealth accumulation in South African savings accounts.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + \frac{R}{n})^{(n \times T)} \]

Where:

\( A \) — Maturity amount (ZAR)
\( P \) — Principal amount (ZAR)
\( R \) — Annual interest rate (decimal)
\( n \) — Compounding frequency per year
\( T \) — Time period in years

Explanation: The formula calculates how much your investment will grow based on the principal amount, interest rate, compounding frequency, and time period.

3. Importance of Compound Interest Calculation

Details: Understanding compound interest helps South African savers make informed decisions about their investments, compare different savings products, and plan for long-term financial goals such as retirement, education funds, or major purchases.

4. Using the Calculator

Tips: Enter the principal amount in ZAR, annual interest rate as a percentage, select compounding frequency, and time period in years. All values must be positive numbers.
