Home Loan Repayment Calculator

Using the online repayment calculator has absolutely zero impact on your credit score. If you transition from the calculator to a preliminary pre-approval check, it is typically treated as a "soft inquiry," which does not damage your credit rating. However, once you proceed to a formal, full application, SA Home Loans will conduct a "hard inquiry" via the credit bureaus, which may temporarily affect your credit score.

The calculator computes your monthly instalment based on three core inputs: the intended loan amount (purchase price minus your deposit), the potential interest rate, and the loan term (usually defaulted to 20 years, though 30-year options can be selected). However, your real-world rate will be heavily influenced by your employment status (salaried vs. self-employed) and your credit history.

The calculator highlights how highly sensitive monthly repayments are to fluctuations. Putting down a larger deposit directly lowers the required loan amount, which reduces your monthly instalments and could also secure you a better interest rate. Conversely, even a minor increase in the interest rate can significantly raise the total interest you will pay over the 20 or 30-year loan term.

Beyond the base monthly repayment, the calculator provides an estimated breakdown of essential legal and administrative costs. These include the Bond Registration Fees which is paid to the bond registration attorneys, the Transfer Costs/Transfer Duty which is paid to the transfer attorneys and SARS (if applicable, based on property value), and the Initiation Fee which is a once-off administrative fee for setting up the loan.
