Car finance and balloon payment calculator

Dealers quote the monthly. This prices the whole deal: the instalment, the NCA fees, the total interest, the legal rate ceiling, and the lump sum a balloon leaves sitting at the end of the term.

A balloon makes the monthly look cheaper by deferring part of the price. It isn't a discount. Interest runs on the full balance, balloon included, for the whole term, and when the term ends you still owe that lump sum in cash. Pay it, refinance it, or hand the car back. Those are the three exits, and knowing the number before you sign is the point of this page. The tool flags a balloon above the roughly 35% of price lenders allow, and warns that a 96-month term won't take one at all.

What to enter:

  • the car price, your deposit and any balloon, in rand
  • the term, your credit band and the rate
  • the NCA initiation fee and monthly service fee, seeded with defaults worth checking against your quote
  • fuel, insurance and upkeep on the shared Running costs card

The headline is the monthly instalment, with the total paid over the term and the total interest beside it. A true-cost strip lays the whole deal against the sticker price: deposit, amount financed, all interest, all service fees. Set a balloon and a dedicated card spells out the trade, showing how much cheaper it makes the instalment, how much extra interest that costs, and the lump sum still outstanding at the end.

The owe-versus-worth chart is worth a minute. It tracks your loan balance against the car's falling value and marks the month you climb above water, which on a long term with a balloon can be a long way in. The full-monthly-cost cards add fuel, insurance and upkeep, with a cost per kilometre against the SARS rate.

Two honest limits: resale value follows a typical SA depreciation curve your exact model won't match, and the NCA fee defaults come from secondary sources rather than the gazette. Use your quote where you have one.
