Car Finance Calculator (South Africa)

How this is calculated

financed = price − deposit;  M = financed·r(1+r)ⁿ ÷ ((1+r)ⁿ − 1)

Worked example: R350,000 car, R35,000 deposit, 15% over 6 years finances R315,000 → about R6,660/month and heavy interest over 72 months. A larger deposit and shorter term are the two levers that matter most.

The instalment is the smaller half of the cost

Vehicle finance quotes are built around a monthly figure, and the monthly figure is not what the car costs. Comprehensive insurance is compulsory while the vehicle is financed and, for a younger driver on a newer car, can approach the instalment itself. Then licensing, fuel, tyres, servicing and the maintenance that arrives once the plan expires. Budgeting to the instalment alone is the most common way a manageable purchase becomes a distressed one by year three.

Deposit, balloon and the depreciation trap

A new vehicle typically loses a substantial share of its value in the first year and continues falling faster than a long loan amortises. With a small deposit and a large balloon, the outstanding balance can exceed the trade-in value for most of the term — the position known as being upside down. Selling then requires paying in the shortfall, and rolling it into the next agreement carries the deficit forward.

A larger deposit and a smaller balloon cost more each month and keep you the right way up. The balloon in particular should be treated as a debt you are already saving toward, not a problem for future you.

Linked, fixed, and the rate you are quoted

Most vehicle finance is linked to prime, so the instalment moves with the repo rate; a fixed rate costs more initially and removes that risk. The rate offered depends on your credit record, the deposit and the vehicle's age, and dealers frequently present finance from a single provider. Getting a pre-approval from your own bank before walking in changes the conversation, because you arrive with a rate to beat rather than a rate to accept.

Extras that arrive at signing

Expect an initiation fee and a monthly service fee, both capped by the National Credit Act, and expect to be offered a service plan, extended warranty, tyre and rim cover and credit life. Some are worthwhile; all are negotiable; and each one added to the financed amount is borrowed and paid interest on for the full term. Ask for the total amount repayable with and without each item before deciding.
