How this calculation works
Trade-in equity is offer less settlement. Cash first covers negative equity; remaining cash and positive equity reduce the next purchase price. If selected, an uncovered shortfall is added to the new finance estimate, otherwise it is shown as extra cash needed.
A worked example
R180 000 trade-in less R200 000 settlement leaves R20 000 negative equity. R30 000 cash covers it and leaves R10 000 toward the next car.
Assumptions & limitations
- Use an actual settlement quote valid for your date; outstanding statement balance may differ. Rolled-over negative equity requires lender approval and increases debt. Taxes, fees, deposits already paid and new-loan interest are excluded.
