Compare car finance terms and balloon payments
Estimate your monthly vehicle finance instalment, interest and fees. Start with the 60-month default, then compare 48, 60, 72, 84 and 96 months using the same deposit, rate and final balloon.
A longer term usually reduces the monthly payment but increases total interest. A balloon reduces instalments by leaving capital due at the end. This calculator bases its balloon percentage on the vehicle price after deposit, excluding the initiation fee.
Terms and balloon limits depend on the lender, vehicle and credit assessment. Standard Bank lists 12–84 months, with 84 months requiring discussion. The 96-month and 40% balloon settings are scenarios, not a promise of availability. Balloon refinancing requires a new application and is not guaranteed.
Method, fees and assumptions
The monthly rate is the entered annual percentage divided by 12. The present value of the final balloon reduces the capital used in the standard annuity formula. When selected, the configured initiation fee is capitalised and the monthly service fee is added separately.
Total interest equals instalments over the term plus the balloon, minus the financed amount and capitalised initiation fee. Service fees are excluded from interest. Total repayments include interest, fees and the balloon but exclude the deposit. Instalments round to cents; rounding can change total interest by up to half a cent per month.
Use your lender quote to check fees and rate. Insurance, fuel, maintenance, warranties and other optional products are excluded. This estimate assumes the entered rate remains constant.

Yes. The term table holds the deposit, rate, balloon amount and fee choice constant. The 96-month option is a scenario; available terms and balloon limits vary by lender and vehicle.
A balloon lowers monthly instalments by leaving capital outstanding until the end. At a positive interest rate this generally increases total interest compared with repaying all capital over the same term.
It includes the finance instalment and, when selected, the configured monthly service fee. The initiation fee is capitalised. Insurance, maintenance, fuel and other optional products are excluded; check your lender quote.
Ask your lender for a dated settlement quote and any applicable charges. Refinancing a balloon is a new credit application and is not guaranteed.
