How much does a R100,000 home loan cost per month at 10.75% prime?
A R100,000 home loan repaid over 20 years at the prime lending rate of 10.75% costs about R 1 015 a month. The South African Reserve Bank raised the repo rate by 25 basis points to 7.25% on 23 September 2026, and prime moved to 10.75% from 10.50%, effective 25 September 2026.

How much did the September 2026 hike add to a R100,000 bond?
On a R100,000 home loan over 20 years, the 25 basis point hike adds about R 17 a month: from R 998 at 10.50% to R 1 015 at 10.75%. That is bond.co.za's own calculation, using the SARB rates as at 25 September 2026.
What does that mean for a bigger bond?
Repayments scale in proportion to the loan, so you can read across from the R100,000 figure. The table shows bond.co.za's calculation over 20 years at prime, before and after the hike, as at 25 September 2026.
| Loan amount | At 10.50% | At 10.75% | Extra per month |
|---|---|---|---|
| R 100 000 | R 998 | R 1 015 | R 17 |
| R 500 000 | R 4 992 | R 5 076 | R 84 |
| R 1 000 000 | R 9 984 | R 10 152 | R 168 |
| R 1 500 000 | R 14 976 | R 15 228 | R 253 |
Will my own bond cost exactly this?
Probably not exactly. Your bank prices your home loan as prime plus or minus a margin set by your credit profile, deposit and term, so your rate may sit above or below 10.75%. Fees and insurance are extra. Use bond.co.za's home loan calculator for your own rate and term, or the rate increase impact calculator to see what the next move would add.
