How loan repayments work in South Africa
SA Prime Rate — 10.25%
The prime lending rate is 10.25% as of April 2026 (repo rate 6.75% + 3.5%). Most SA home loans are linked to prime — banks typically charge prime + 0% to prime + 2% depending on your credit profile.
Amortization
Each monthly payment covers interest first, then principal. Early payments are mostly interest — principal reduces faster over time.
Affordability rule
Banks use the National Credit Act — monthly repayments should not exceed 30% of your gross monthly income for home loans.
Extra payments
Paying extra into your bond monthly can save years off your term and tens of thousands in interest — even R500/month makes a big difference.
