The Loan Repayment Fits — But Can I Actually Afford the Car After Rego, Insurance and Fuel?

Quick answer: The finance repayment is only one part of car affordability. Add insurance, registration, fuel or charging, servicing, tyres, parking/tolls and a repair buffer. A car can pass the loan-payment test and still be unaffordable to own.

Questions borrowers commonly ask

I can manage the repayment, but what happens after fuel, insurance, rego and maintenance?
Why are people defaulting on car loans even when the weekly payment looked affordable?
I need a work car at 19 — how much of my income should the whole car really consume?

Use the calculator below before choosing the vehicle

Run the total cost using a real insurance quote and your actual kilometres, not generic assumptions.

Young drivers can be hit hardest by insurance

The insurance premium can materially change the comparison between a cheap performance car and a more ordinary vehicle.

Older cars need a repair allowance

A cheap purchase price is not enough if the borrower has zero cash for a gearbox, tyres or major service.

For home buyers, the full car cost also slows deposit saving

The debt repayment affects servicing, while the operating cost affects monthly savings capacity.

Frequently asked questions

Does the calculator include depreciation?

No; it focuses on recurring cash-flow costs.

Should I include annual insurance monthly?

Yes, convert it to a monthly provision.

How much should I allow for repairs?

Use the vehicle’s realistic age/condition and service history; older cars need more contingency.

Does this tell me lender approval?

No.

Why does this matter if the lender approved me?
