1. What is the Home Loan Credit Calculator?

The Home Loan Credit Calculator estimates the affordable principal amount for a home loan in South Africa based on credit score, income, expenses, and loan terms. It helps potential homebuyers determine how much they can realistically borrow.

2. How Does the Calculator Work?

The calculator uses the home loan formula:

\[ Affordable\ P = Credit\ Score\ Adjustment \times (Income \times Ratio - Expenses) \times \frac{(1 + r)^n - 1}{r \times (1 + r)^n} \]

Where:

\( Credit\ Score\ Adjustment \) — Adjustment factor based on credit score (decimal)
\( Income \) — Monthly income in ZAR
\( Ratio \) — Debt-to-income ratio (decimal)
\( Expenses \) — Monthly expenses in ZAR
\( r \) — Monthly interest rate (decimal)
\( n \) — Loan term in months

Explanation: The formula calculates the maximum principal amount that can be afforded based on available income after expenses, adjusted for creditworthiness and loan terms.
