1. What is the Loan Repayment Formula?

The loan repayment formula calculates the fixed monthly payment required to pay off a loan over a specified period. This formula is widely used in South Africa for mortgages, personal loans, and other types of installment credit.

2. How Does the Calculator Work?

The calculator uses the standard amortization 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 ÷ 100)
\( n \) — Total number of payments (loan term in years × 12)

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

3. Importance of Loan Repayment Calculation

Details: Accurate loan repayment calculation helps borrowers understand their financial commitments, compare different loan offers, and plan their budgets effectively. In South Africa, this is particularly important given varying interest rates and loan terms.

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 accurate results.
