No balloon vs 30% balloon — side by side

A R450,000 vehicle over 60 months at prime + 2%, same deposit:

Scenario	Monthly	End balloon	Total cost of credit
No balloon	R8,810	R0	R134,400
20% balloon	R7,360	R90,000	R155,600
30% balloon	R6,635	R135,000	R166,100

Illustration only. The lower monthly buys you ~R2,200 less per month — and costs you ~R32,000 more in total. Always run the full comparison.

Frequently asked questions

How does car finance work in South Africa?+

You take a credit agreement with a bank or finance house secured against the vehicle (called an instalment sale agreement). The bank pays the dealer; you repay over 24–72 months. Title transfers to you once the loan is settled. Default risks repossession.

What's a balloon payment?+

A balloon (or residual) is a lump sum due at the end of the loan term, usually 10–40% of the vehicle price. It lowers your monthly payment but means you face a large bill at the end. You can pay it, refinance it or trade the car in to clear it.

Is a balloon payment a good idea?+

Rarely. The lower monthly looks attractive but you pay interest on the balloon for the full term while never reducing it. On a 60-month loan with a 30% balloon, you pay roughly 20–25% more in total interest than a no-balloon equivalent.

What interest rate should I expect on car finance?+

Most banks quote prime + 1% to prime + 3%, depending on your credit profile. With prime at 10.25% in May 2026, expect 11.25–13.25% per year. Get quotes from at least 3 finance houses.

Do I need a deposit for car finance?+

No, but a deposit reduces the financed amount, lowers your monthly payment and usually gets you a better rate. 10% is a common minimum on used cars; new cars often go through with no deposit if your credit is strong.

What's the maximum term for car finance?+

Most banks cap at 72 months (6 years), with 60 the most common. Some lenders offer 84 months but the depreciation outpaces capital repayment for the first 4 years — you'd be in negative equity for most of the term.
