How this calculator works
Loan = available payment × (1 − (1 + r)^−n) ÷ r, then add deposit and trade-in
- available payment
- your budget less insurance and running costs
- r
- the monthly interest rate
- n
- the number of monthly payments
Important considerations
- Insurance, fuel, tax and maintenance often add 30–50% to the payment.
- Longer terms raise affordability but risk negative equity.
