How insurance premiums are calculated in South Africa
What insurers actually look at when pricing your monthly premium — and the levers you can pull to bring it down.
Quick summary
South African insurers price on three buckets: the driver (age, claims history, occupation, credit score), the vehicle (value, model, security) and the location (where you sleep and where you work). Telematics adds a fourth lever for app-friendly drivers.

Typical cost in SA
The national median car premium in SA is around R720/month in 2026. A 25-year-old in Sandton can pay R1,400; a 45-year-old in Bloemfontein the same car can pay R380.
Frequent questions
- Why did my premium go up if I didn't claim?
- SA insurers reprice the book annually to track inflation, parts costs, claims experience in your area and your age band. Even claim-free policies typically rise 7–12% per year. Always shop at renewal.
- Does my credit score affect my car insurance premium in SA?
- Yes. Most direct insurers (OUTsurance, Discovery, MiWay) use a credit-based insurance score. Paying accounts on time and keeping utilisation below 35% helps.
- Can I lower my premium without changing cover?
- Yes — raise your voluntary excess, fit a tracker, declare a more accurate annual mileage, and move comprehensive cars off the street into a garage where possible.
The driver bucket
Age, marital status, claims-free years, occupation and credit profile all feed the score. Drivers under 25 carry the steepest loadings; the curve flattens at 35 and rises again past 70. Three consecutive claim-free years can drop your premium by 15–25%.
The vehicle bucket
Retail value, theft index, parts availability, engine size and fitted security (Thatcham-rated tracker, gear lock, alarm) all matter. The same model can carry a 25% premium gap between trim levels if one is on the 'most-stolen' list.
The location bucket
Two postcodes drive your premium: where the car sleeps overnight and where it's parked during the day. Gauteng generally carries the highest loading, the Free State and Northern Cape the lowest. Locked garage overnight knocks 5–10% off vs street parking.
