# Fixed vs variable home loan in South Africa: which should you pick? - Canonical URL: https://bond.co.za/news/fixed-vs-variable-home-loan-south-africa - Author: Neil B - Published: 2026-09-06 - Last updated: 2026-10-12 Market newsBank products With the Reserve Bank’s next rate decision due on 19 Nov 2026 and prime at 10.75%, South African bond applicants are asking one question: lock in a fixed rate, or stay variable? Here’s how the two actually compare.

Should your bond be fixed or variable? ### Where the choice sits right now The repo rate is 7.25% and the prime lending rate is 10.75%, effective 25 Sept 2026, after two 25 basis point hikes in 2026 — May and September — the first increases since May 2023. Inflation cooled to 4.3% in July (down from 5.0% in June, per Stats SA), but it remains above the Reserve Bank’s 3% point target, and the September hike went through unanimously. The next decision lands on 19 Nov 2026, and no one can promise which way it goes — which is exactly the kind of uncertainty fixed rates exist for — and what each path costs is in our [breakdown of the September 2026 hike](https://bond.co.za/news/sarb-september-2026-rate-hike-bond-impact). Most South African home loans are variable, meaning prime-linked: your instalment moves within weeks of every MPC announcement. A fixed-rate home loan does what the name says — one rate, agreed upfront, for a set window (typically one to five years, depending on the lender) — after which the loan usually reverts to a variable, prime-linked rate. The catch: banks price that certainty at a premium — and how wide that premium runs varies by lender, as our [piece on what banks actually charge](https://bond.co.za/news/home-loan-rates-what-banks-actually-charge) shows. ### The real price of certainty South African banks typically quote fixed rates at roughly 1–2 percentage points above the prevailing prime rate. On a R1 million bond over 20 years, the maths is stark: at 10.75% the instalment is about R 10 152 a month; at 11.75% it is roughly R 10 837 — **about R 685 more every month, before fees** (illustrative reducing-balance calculation). That premium is the price of the insurance. For it to pay off, the variable rate you rejected must rise by more than your premium during the fixed window — or, if rates fall, you simply pay more while prime-linked borrowers benefit. And rates do fall. Prime spent late 2025 at a cycle low of 10.25% after the cutting cycle that began in September 2024, and July’s cooling inflation print showed the committee still watches the downside as closely as the upside — the September hike came despite it, not because inflation accelerated. Fixing at today’s premium is a bet that the next one to two percentage points of rate movement are upward. It might be. It is not a certainty, and no lender will tell you otherwise. ### A third factor: the benchmark itself is changing There is also a quieter reason to understand your pricing before you sign. The SARB has proposed retiring the prime lending rate and pricing loans directly off the repo rate from 2027 — prime has been a fixed 350-basis-point markup on repo since 2001, and the change makes that markup explicit rather than folding it into a single number. Existing borrowers are unaffected, but new applicants should expect to see quotes expressed as “repo plus a margin” in future, and to compare offers on the margin, not the headline label. Our [prime rate tracker](https://bond.co.za/prime-interest-rate-south-africa-today) keeps the current numbers side by side. ### So which should you pick? Strip away the forecasting and the decision has a clear structure. If one more rate hike would genuinely strain your budget — if prime at 11.50% or 12.00% means sleepless nights — a fixed rate buys you predictability at a known, budgeted price, and that has real value regardless of what the MPC does. If your budget has room to absorb a few hundred rand either way, the variable rate is usually cheaper over time: you skip the premium, and you automatically benefit if the next move is down. Our [rate increase impact calculator](https://bond.co.za/rate-increase-impact-calculator) shows what a one or two percentage point rise would add at your bond size. Either way, run the numbers before you sign. Our [bond calculator](https://bond.co.za/bond-calculator) will show your instalment at today’s prime and at a stressed rate, and our [home-loan rate comparison](https://bond.co.za/home-loan-rate-comparison-south-africa) shows how the banks’ pricing actually differs. The cheapest insurance is knowing your own break-even point in advance. ### What to watch next - The MPC statement at 15:00 on 19 Nov 2026, and what it signals about the path after September’s unanimous hike. - How banks price fixed-rate offers as the SARB’s proposal to retire the prime benchmark moves toward its 2027 transition window. - Whether inflation keeps easing toward the 3% target point — the main thing that decides whether the September hike was the peak.
