Vehicle finance gets talked about as if it is one product with one interest rate. In practice, it can be legally structured in two different ways, it is priced under its own ceiling in the National Credit Act — different from a personal loan or a mortgage — and a common feature (the balloon payment) can make the deal look cheaper each month while quietly shifting real risk to the end of the term.
Two different legal structures, not one
Some vehicle finance is a traditional instalment sale agreement: the vehicle is delivered to you, but ownership only transfers once every instalment has been paid — legally, the lender owns the car until the final payment clears. Other vehicle finance is structured as a straight secured loan, where the car is yours from day one and simply serves as the lender's security for the debt. These are not interchangeable labels for the same thing — check which structure a specific offer actually uses. As one concrete example, Capitec's own Vehicle Loan is explicit that "the vehicle belongs to you from day one," which is the secured-loan structure, not an instalment sale.
The rate ceiling is different from a personal loan
Vehicle finance falls under the National Credit Act's "other credit agreements" category, which caps the maximum interest rate at the repo rate plus 17 percentage points. That sits between the caps for the two categories either side of it: unsecured personal loans are capped higher, at repo plus 21 percentage points, and mortgages are capped lower, at repo plus 12 percentage points. The pattern makes sense — the vehicle itself is security for the debt, so the ceiling sits below an unsecured personal loan, but the loan is still shorter and the collateral depreciates faster than a house, so the ceiling sits above a mortgage. See our explainer on how the repo rate and prime rate relate for how these formulas actually move over time.
What actually moves your specific rate
A few concrete factors do most of the work: a bigger deposit (commonly 10% to 20% of the purchase price) reduces both your rate and the total amount you finance; new vehicles are typically priced lower than used ones, since a newer car is worth more as security and depreciates more predictably; and your own credit profile and the loan term you choose both feed into the lender's own risk pricing, the same as any other credit product.
Balloon payments: lower now, a real bill later
Many vehicle finance deals offer a balloon (or "residual value") payment option: instead of paying off the full price across your monthly instalments, a chunk of it — commonly 20% to 30% of the purchase price — is deferred to a single lump sum due at the end of the term. This lowers every monthly instalment, because you are financing less of the capital month to month. The real risk sits at the end: the balloon amount is fixed upfront based on an assumed future value, but if the car is actually worth less than that when the term ends, you still owe the full balloon regardless — you may need to refinance it, sell the car and cover the shortfall, or find the cash outright. A lower monthly payment via a balloon is not automatically a cheaper deal overall; it is a different shape of the same total cost, with the risk moved to a specific date instead of spread evenly across the term.
Frequently asked questions
Is a lower monthly instalment always the better deal?
Not automatically. A lower monthly payment achieved through a balloon structure defers a real lump sum to the end of the term rather than reducing what you actually pay overall — compare the total cost, not just the monthly figure.
Do I own the car while I am still paying it off?
It depends on how the specific agreement is structured. Under a traditional instalment sale agreement, ownership only transfers once the final payment is made. Under a secured vehicle loan, you own the car immediately and the lender holds it as security for the debt.
Should I put down a deposit if I can afford to skip it?
Usually yes — a larger deposit typically reduces both your interest rate and the total amount financed, though the exact effect depends on the specific lender.
