1. What is the Mortgage Repayment Formula?

The mortgage repayment formula calculates the fixed monthly payment required to fully repay a home loan over a specified term. This formula is widely used in South Africa's banking and real estate sectors for mortgage affordability assessments.

2. How Does the Calculator Work?

The calculator uses the standard mortgage repayment formula:

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

Where:

\( M \) — Monthly mortgage payment (ZAR)
\( P \) — Principal loan amount (ZAR)
\( r \) — Monthly interest rate (annual rate ÷ 12 ÷ 100)
\( n \) — Total number of monthly payments (loan term in years × 12)

Explanation: The formula calculates the fixed payment that covers both principal and interest, ensuring the loan is fully repaid by the end of the term.

3. Importance of Mortgage Calculation

Details: Accurate mortgage calculation helps homebuyers understand their financial commitments, assess affordability, and compare different loan options from South African banks.

4. Using the Calculator

Tips: Enter the principal amount in ZAR, annual interest rate as a percentage, and loan term in years. Ensure all values are positive and realistic for the South African mortgage market.
