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 an accelerating rate over time, 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:

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

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 savings will grow when interest is compounded at regular intervals, taking into account the principal, interest rate, compounding frequency, and time period.

3. Importance of Compound Interest

Details: Understanding compound interest is crucial for financial planning in South Africa. It helps investors and savers project future savings growth, compare different investment options, and make informed decisions about long-term financial goals.

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 to calculate accurate results.
