Your car finance approval depends on three numbers: your income, your existing debts, and the loan amount you're asking for.
Most people applying for vehicle financing focus on whether they can afford the monthly repayment. Lenders look at something different. They calculate how much debt you can service based on your income after all your other commitments, then decide if your request fits within that limit. If you earn $80,000 a year, have a $400 monthly personal loan, and want to borrow $35,000 for a family car, the lender isn't just checking if you can pay $650 a month. They're running a formula to see if that monthly repayment keeps your total debt servicing below their threshold, which is typically around 30-40% of your gross income.
Income Verification Across Different Employment Types
Lenders need to confirm your income is stable and ongoing. For employees, this usually means providing recent payslips and tax returns. If you're self-employed, you'll need tax returns for the past two financial years, and some lenders want to see your business activity statements as well.
Consider someone based in Caulfield who runs their own consulting business. They're looking at a used Car Loan for around $28,000. Their income varies between $6,000 and $9,000 a month depending on client work. The lender averages their income over the two-year period shown in their tax returns, then applies that figure to the debt servicing calculation. If their average comes to $84,000 annually and they have no other debts, they can typically service a loan amount up to around $30,000 to $35,000 without issues. The monthly repayment on $28,000 over five years sits comfortably within their capacity.
How Your Existing Debts Affect Approval
Every ongoing commitment reduces how much you can borrow. This includes credit cards, even if you pay them off each month. Lenders assess the credit limit, not the balance.
If you have a credit card with a $10,000 limit, the lender treats it as if you're servicing around $300 a month, regardless of whether you owe $50 or $5,000. A $15,000 personal loan with $400 monthly repayments and that credit card together use up $700 of your monthly capacity before the car finance application even starts. For someone earning $70,000 a year, those two commitments already consume a significant portion of their available servicing capacity. Paying off or closing unused credit accounts before you apply can genuinely change the loan amount you're approved for.
Deposit Size and What It Does to Approval Odds
A larger deposit reduces the amount you're borrowing and lowers the lender's risk. This matters more with used vehicles than new ones. For a certified pre-owned vehicle, lenders typically prefer you to have at least 10-20% of the purchase price as a deposit, though no deposit options do exist if your income is strong enough to support the full loan amount.
Putting down $8,000 on a $40,000 vehicle means you're borrowing $32,000 instead of the full amount. The monthly repayment drops, your debt servicing ratio improves, and the lender sees less risk because you have equity in the vehicle from day one. In our experience, buyers in the Eastern Suburbs of Melbourne who can provide a deposit often access lower car finance interest rate options as well, though the rate you're offered depends on your credit file and the lender's assessment.

Credit History and How Far Back Lenders Look
Your credit file shows defaults, court judgments, bankruptcies, and your repayment history on existing debts. Most lenders focus on the past two years, but serious issues like defaults stay visible for five years.
A $500 unpaid phone bill that went to default three years ago can delay or reduce your finance approval, even if everything else in your application is solid. Lenders don't automatically reject applications with past defaults, but they do adjust the interest rate or reduce the loan amount they're willing to offer. If you know there's something on your credit file, checking it before you apply gives you time to either pay it off or prepare an explanation. Some lenders who specialise in vehicle finance for buyers with less-than-perfect credit will still approve applications, but expect the rate to be higher than standard offers.
Vehicle Age and Type in the Approval Process
The car you're buying affects whether the application gets approved. Lenders treat a three-year-old Toyota differently to a twelve-year-old convertible. Most secured Car Loan products cap the vehicle age at around ten to fifteen years old at the end of the loan term.
If you're looking at an electric vehicle financing application, some lenders offer specific green Car Loan products with slightly lower rates or longer terms. A new electric car valued at $55,000 might attract better terms than a ten-year-old luxury car at the same price, simply because the lender sees stronger resale value and lower default risk. For buyers considering a ute or van for work purposes, a business car loan structured through your company can change the approval criteria entirely, as lenders assess business income and cash flow instead of personal income.
Application Timing and Pre-Approval
Getting a pre-approved car loan before you start shopping tells you exactly what loan amount you can access. This doesn't lock you into borrowing that full amount, but it does give you a firm number to work with when negotiating with a car dealer.
A pre-approval typically lasts 60 to 90 days and doesn't require you to have chosen a specific vehicle yet. Once you find the car you want, the lender just needs to verify the vehicle details and confirm nothing in your financial situation has changed. For buyers looking across dealership options in areas like Brighton or Malvern, having finance approval sorted before you walk into the yard shifts the conversation from whether you can buy to how much you're willing to pay. Dealer financing can be convenient, but it's worth comparing what you've been pre-approved for through a broker against what the dealership offers.
Balloon Payments and How They Affect What You're Approved For
A balloon payment is a lump sum due at the end of your loan term. It reduces your monthly repayment during the loan period, which can help you get approved for a larger loan amount by keeping your debt servicing ratio lower.
If you're borrowing $40,000 over five years with a 30% balloon payment, you're only repaying $28,000 across the monthly payments, with $12,000 due at the end. The monthly repayment might drop from $750 to around $525, which improves your serviceability and could get you across the line if your income is borderline. The catch is you need to either pay that $12,000, refinance it, or sell the vehicle when the term ends. Buyers who plan to upgrade or sell the car in a few years often find this structure useful, but if you're planning to keep the vehicle long-term, a standard loan without a balloon usually makes more sense.

Frequently Asked Questions
What income documents do I need for a car loan application?
Employees typically need recent payslips and tax returns. Self-employed applicants usually provide tax returns for the past two financial years and business activity statements to verify their income.
How does a credit card limit affect my car loan approval?
Lenders assess the credit limit, not your current balance. A $10,000 credit card is treated as if you're servicing around $300 per month, which reduces the loan amount you can borrow for your vehicle.
Do I need a deposit for a car loan?
A deposit is not always required, though having one improves your approval odds and may reduce your interest rate. For used vehicles, lenders typically prefer at least 10-20% of the purchase price as a deposit.
How long does a car loan pre-approval last?
A pre-approval typically lasts 60 to 90 days. It gives you a confirmed loan amount before you choose a vehicle, and the lender finalises the loan once you provide the vehicle details.
What is a balloon payment and how does it help with approval?
A balloon payment is a lump sum due at the end of your loan term. It reduces your monthly repayment during the loan, which improves your debt servicing ratio and may help you get approved for a larger loan amount.
