The Complete Guide to Home Loan Repayments in South Africa
Last reviewed:
A home loan (bond) is likely the largest financial commitment you will ever make. Over 20–30 years, the interest alone can exceed the original loan amount. Understanding how repayments work — and how small changes can save you hundreds of thousands of rands — is essential.
How Home Loan Repayments Work
Your monthly repayment is calculated using the standard amortisation formula. In the early years, most of your payment goes toward interest. Over time, the interest portion shrinks and more goes toward principal. This is why extra payments in the early years have the greatest impact.
The Power of Extra Payments
On a R1.5 million bond at 11.75% over 20 years, your monthly repayment is about R15,700. Adding just R1,000 extra per month saves approximately 3–4 years and over R400,000 in interest. Adding R3,000 extra saves 7+ years. The money goes directly to reducing the principal, which reduces future interest.
Bank Fees: Not All Equal
Unlike vehicle finance, home loan fees differ between banks. FNB charges new customers R290/month in service fees versus R69/month at Standard Bank, Absa, and Nedbank. Initiation fees also vary: FNB charges a flat R6,037.50 while others use formula-based fees that can be lower on smaller bonds. Over 20 years, the monthly fee difference alone is R53,040.
Fixed vs Variable Rate
Most SA home loans are variable rate (linked to prime). Fixed-rate options are available for 1–5 years but come at a premium. Variable rate is cheaper on average over the long term but carries the risk of rate increases.
