How to Use This Calculator
Enter your property price, deposit percentage, gross income, employment type, credit score range, and whether you have a salary account with the bank. The calculator scores your profile across the four key factors SA banks use to determine your rate concession, then estimates the rate range you can expect to negotiate.
Use the Rate Impact Comparison tab to see how different rates affect your monthly payment and total interest, and understand the financial value of negotiating a lower rate.
How SA Banks Determine Your Interest Rate
South African banks price home loans at prime plus or minus a spread. The current prime lending rate is 10.25%. The spread — which can range from prime minus 2% to prime plus 3% — depends on your risk profile:
- LTV (Loan-to-Value): The most important factor. LTV below 80% (20%+ deposit) significantly reduces the rate. Below 70% unlocks the best concessions.
- Credit score: A score above 750 signals low risk and enables prime minus rates.
- Employment type: Professionals (doctors, lawyers, CAs) and permanent employees get better rates than the self-employed or contractors.
- Banking relationship: SA banks compete aggressively for full banking relationships. Moving your salary account can reduce your rate by 0.25–0.5%.
Worked Example
Kagiso is a CA (SA) earning R85,000/month. He wants to buy a R2,500,000 property and has saved a 25% deposit (R625,000). His credit score is 810. He banks at FNB where his salary is paid.
Profile scoring: 25% deposit (−75 bps) + excellent credit (−100 bps) + professional (−75 bps) + salary account (−50 bps) = −300 bps total adjustment.
Estimated rate: 10.25% − 3.0% = 7.25%. On a R1,875,000 bond over 20 years, this is approximately R14,800/month vs R17,200/month at prime — a saving of R2,400/month or R576,000 in total interest.
Frequently Asked Questions
Can I negotiate my home loan interest rate in South Africa?
Yes — SA banks actively compete for home loan business and rates are always negotiable. Banks rarely offer their best rate upfront. Applying through a bond originator (ooba, BetterBond, SA Home Loans) automatically creates competition between banks, as all major banks submit competing offers simultaneously. Premium profiles (high deposit, excellent credit, professional) regularly achieve prime minus 1% to prime minus 2%.
What is the current home loan prime rate in South Africa?
The current South African prime lending rate is 10.25% (effective May 2026). The prime rate is the SARB repo rate (currently 6.75%) plus 3.5%. Home loans are priced relative to prime — most borrowers pay between prime minus 1% and prime plus 1.5%, depending on their risk profile.
What deposit percentage gets the best home loan rate?
A deposit of 20% or more (LTV of 80% or less) is where rate improvements become significant. At 30%+ deposit (LTV 70%), you can typically achieve prime minus 1.5% or better with a good credit profile. The relationship between LTV and rate is non-linear — the jump from 90% LTV to 80% LTV makes a bigger rate difference than the jump from 80% to 70%.
Does applying to multiple banks hurt my credit score?
Multiple home loan enquiries within a 14-day window are typically treated as a single enquiry by South African credit bureaus (TransUnion, Experian, Compuscan) for credit scoring purposes. Using a bond originator is therefore safe — they submit simultaneously and the impact is treated as one enquiry. Spreading applications over weeks can be more damaging.
Can I renegotiate my existing home loan rate?
Yes. If your property has appreciated and your LTV has fallen significantly, or your credit profile has improved, you can request a rate review from your bank. Alternatively, you can threaten to switch to another bank (bond switch). SA banks often match competitor rates rather than lose a home loan client. The NCA allows you to switch your home loan to another bank at any time, subject to bond cancellation and re-registration costs.
