General information only: This guide does not consider your objectives, financial situation or needs. Eligibility and loan terms depend on financier assessment.
How car finance works from budget to settlement
A car loan pays for an approved vehicle purchase and is repaid over an agreed term. Most car loans are secured: the financier registers an interest over the vehicle and can have enforcement rights if the contract is not met. The debt does not automatically disappear if a repossessed vehicle sells for less than the amount owed.
The useful way to understand the process is as a sequence. First set an ownership budget. Then check whether the borrower, vehicle and proposed structure fit a product. Only after those checks does a rate comparison become meaningful. Final approval, signed documents, insurance, seller verification and settlement still sit between an initial outcome and taking ownership.
- Budget: include purchase and ownership costs, not just the repayment.
- Eligibility: check borrower, income, credit, vehicle and loan criteria.
- Compare: hold the amount, term and balloon constant across options.
- Verify: supply the evidence required for final assessment.
- Settle: confirm the vehicle, seller, insurance and payment instructions.
Choose the path that matches how you are buying
“Car finance” is not one transaction. A new vehicle from a dealer, a used dealer vehicle, a private purchase and a refinance create different evidence and settlement risks.
What lenders assess—and why each factor matters
Approval is not produced by a credit score alone. Responsible lending obligations and financier policy require a broader assessment. A strong result in one area does not erase an unaffordable structure or an ineligible vehicle.
Vehicle age matters because the asset is the security and continues to depreciate during the term. A lender may limit the term or amount so the vehicle is not too old at maturity. Asset backing can matter in some commercial policies because it changes how the lender classifies risk, but it does not necessarily mean a home is taken as security. The credit contract controls the actual security and guarantee position.
Compare the complete cost, not one percentage
The interest rate is used to calculate interest on the outstanding balance. A comparison rate combines that rate with certain ascertainable fees for a prescribed example. It is a better advertising comparison tool, but it is not a personalised quote and does not include every contingent cost.
Keep the amount, term, repayment frequency and balloon identical. Then compare the applicable interest rate, comparison rate, establishment and ongoing fees, scheduled repayment, total amount payable and early-payout terms. A low rate paired with a large upfront fee can cost more than a slightly higher rate with no establishment fee; a longer term can lower the repayment while increasing total interest.
Use the comparison-rate guide for the legal framework and a worked fee example, or the car-loan rates authority page for the factors that can change personalised pricing.
The costs around the car can change the finance decision
The advertised vehicle price is not always the amount needed to take legal ownership and drive away insured. Depending on the transaction and jurisdiction, the cost stack can include motor vehicle duty, registration and transfer charges, CTP or an equivalent motor injury scheme, comprehensive insurance, dealer delivery and—in some new-car prices—luxury car tax.
These costs matter to finance because they can increase the requested loan without increasing the vehicle’s market value by the same amount. That can raise the loan-to-value ratio or create a cash contribution requirement. Comprehensive insurance is also commonly required before a secured loan settles; CTP is injury cover and is not a substitute for it.

What still has to happen after an initial decision
A conditional or preliminary outcome is not a promise that funds will be paid. Conditions can include verified identity and income, acceptable bank statements, final vehicle and seller checks, a signed purchase document, satisfactory comprehensive insurance and a valid payout letter where another financier has an interest.
For a private sale, do not send money merely because an application appears approved. Match the VIN across the vehicle, registration, invoice, insurance and PPSR search; verify the seller and any existing financier; and follow the approved settlement instructions.
Follow the complete approval to settlement guide before arranging collection or releasing private-sale funds.
When the plan changes after settlement
A sale, refinance, insurance write-off or missed repayment starts with a different source document. Selling requires a current payout and security discharge. A write-off requires both the insurer settlement and loan payout. Financial hardship requires early contact with the lender rather than another speculative application.
The managing car finance hub covers negative equity, early payout, selling with finance owing, insurance shortfalls, hardship, repossession and what to check after a declined application.
