What Does a R1,700,000 Home Loan Cost in South Africa?

At 10.25% (the current SA prime rate) over 20 years, a R1,700,000 home loan costs R16,687.94 per month and a total of R4,005,105 โ€” with R2,305,105 in interest over the full term. That interest (136% of the loan amount) reflects the cost of borrowing over a long period at the current prime rate.

South African home loans are priced at prime plus or minus a margin based on your credit profile and deposit size. The best buyers with strong credit and a 20%+ deposit can get prime minus 0.5โ€“1%, while first-time buyers with no deposit typically pay prime or prime plus 0.5%. Every 0.5% difference on a R1,700,000 bond changes your monthly payment by approximately R563 per month.

The SARB prime rate was 10.25% in May 2026 following six cuts from the 2024 peak of 11.75%. Further cuts in late 2026 or 2027 would reduce your instalment automatically if your bond is variable-rate.
