Vehicle finance basics
What every South African should know before signing a vehicle finance deal: deposits, interest rates, balloon payments and the real total cost.

Instalment-sale agreements (the standard)
Most South African car finance is an instalment-sale agreement (also called a "hire-purchase"). The bank owns the car until you've paid it off; you pay a fixed monthly instalment over 12–84 months. Interest is usually quoted as "prime ± x".
Deposit
A 10% deposit is common. Larger deposits reduce both your monthly payment and the interest you pay over the life of the loan. They also lower your loan-to-value ratio, which can unlock a better rate.
Balloon (residual) payment
A balloon is a large lump-sum due at the end of the loan — typically 20–35% of the vehicle's value. It cuts the monthly instalment significantly, but you owe a big bullet payment when the term ends. Most people refinance the balloon, sell the car, or trade it in.
Balloons are seductive but expensive. You pay interest on the balloon throughout the term, so the total cost of ownership rises. Use them only if you genuinely plan to sell or trade at the end.
Worked example
R 400 000 car, 10% deposit (R 40 000), 60 months at 12% interest:
- No balloon: ~R 8 010/month, total interest ≈ R 120 600.
- 30% balloon (R 120 000): ~R 6 060/month, but you owe R 120 000 at month 60. Total interest ≈ R 145 200 — about R 25 000 more.
Costs they don't quote you
- Initiation fee (R 1 207.50 max under the National Credit Act).
- Monthly admin fee (R 69 max).
- Comprehensive insurance (mandatory if financed).
- Service plan, maintenance plan, tyre & rim cover (optional but commonly bundled).
- Licensing, fuel, tyres, depreciation.
The honest test
Before signing, work out the total cost of the deal (instalments × months + deposit + balloon + fees) and compare it to the cash price. The difference is what the credit actually costs you. If it shocks you, consider a cheaper car.
