1. What is the Mortgage Repayment Calculator?

The Mortgage Repayment Calculator estimates your monthly home loan payments using Bank SA's standard amortization formula. It helps you understand the financial commitment of a mortgage before applying.

2. How Does the Calculator Work?

The calculator uses the standard mortgage formula:

\[ M = P \times \frac{r \times (1 + r)^n}{(1 + r)^n - 1} \]

Where:

\( M \) — Monthly payment (ZAR)
\( P \) — Principal loan amount (ZAR)
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Total number of payments (loan term in years × 12)

Explanation: This formula calculates the fixed monthly payment required to fully amortize a loan over its term, accounting for both principal and interest.

3. Importance of Mortgage Calculation

Details: Accurate mortgage calculations help borrowers understand affordability, compare loan options, and plan their budget effectively. It's essential for making informed home-buying decisions.

4. Using the Calculator

Tips: Enter the loan amount in ZAR, annual interest rate as a percentage, and loan term in years. Ensure all values are positive and realistic for accurate results.

Q1: What is included in the monthly payment?
A: The calculated payment includes principal and interest. Additional costs like property taxes, insurance, and fees may not be included.
