The Balloon Trade-Off, Made Visible
Every balloon payment is the same bargain dressed differently: you accept a lower monthly instalment now in exchange for paying more in total and owing a lump sum later. The two charts above show both halves of that bargain at once. The green chart falls as the balloon rises — that's the instalment relief dealers sell. The amber-and-navy chart climbs — that's what it costs you: more total interest, and a larger lump sum waiting at the end of the term.
Why the Total Cost Goes Up
The balloon portion of your loan is never reduced during the term — you pay interest on it every single month, right up to the final payment, without chipping away at the capital. So the more of your car's price you park in the balloon, the more interest you rack up on money you haven't started repaying. That's why a 35% balloon can feel affordable monthly yet quietly cost tens of thousands of rand more across the deal.
Remember: You Don't Choose the Balloon
This tool lets you slide the balloon anywhere from 0% to 40% so you can see the effect — but in a real deal, the bank decides what it will approve, based on your credit scoring, whether the vehicle is new or near-new, and the term. Older or high-mileage vehicles often qualify for a reduced balloon or none at all. Commonly approved residuals on qualifying deals sit between 20% and 35%. Treat the high end of this slider as illustrative, not a target to aim for.
A Sensible Way to Use a Balloon
If you do take a balloon, have a plan for the lump sum on day one — ideally saving a twelfth of it each month into a separate pocket so it's covered when the term ends. Use this visualiser to find the smallest balloon that makes the instalment workable, rather than the biggest one a dealer will offer. The difference between those two choices, across a six-year deal, is real money.
