How a balloon payment works

A balloon (or residual) is a lump sum you agree to pay at the end of the loan. Because part of the loan is pushed to the end, your monthly instalment is lower. But you pay interest on the balloon for the whole term, so the car costs more overall.

When the balloon falls due, you need to pay it in cash, refinance it, or trade the car in. Cars lose value quickly, so the car may be worth less than the balloon by then. Banks usually allow a balloon of up to about 35% to 40% of the price.

The fees on a car loan

The National Credit Act caps what a lender may charge. For vehicle finance, the initiation fee is at most R165 plus 10% of the amount above R1 000, up to R1 050, plus VAT: R 1 207,50 on almost every car loan. The monthly service fee is at most R60 plus VAT: R 69,00.

Not included here: comprehensive insurance (required by the bank), credit life cover, and any extras sold with the car. Ask for a pre-agreement quote, which by law must show every cost.

Quick answers

What interest rate will I get on car finance?

Banks typically quote from about prime (10,75%) to prime plus 4%, depending on your credit record, deposit and the car. The calculator starts at prime + 1% (11,75%), a common quote.

What is a balloon payment?

A lump sum you owe at the end of the loan, which lowers your monthly instalment. On a R 400 000 car over 72 months, a 30% balloon cuts the instalment from R 7 861 to R 6 705, but you still owe R 120 000 at the end and pay R 36 807 more interest.

What fees can the bank charge on vehicle finance?

Under the National Credit Act, an initiation fee of at most R 1 207,50 and a monthly service fee of at most R 69,00, both including VAT.
