How much can I borrow for a car loan? What lenders actually look at

If you have ever tried to work out how much you can borrow for a car before walking into a dealership, you are not alone. It is one of the most common questions car buyers ask, and the answer is not as simple as a single number.

Lenders do not just look at your income. They assess a combination of factors including your living expenses, existing debts, credit history, the loan term, and how much deposit you have. Understanding how these fit together puts you in a much stronger position when you apply. You can also explore car loan options with Finwave before you even step foot in a dealership.

This article breaks down exactly what lenders look at and gives you indicative examples to help you plan.

HOW LENDERS CALCULATE YOUR BORROWING CAPACITY

Borrowing capacity comes down to one core question: after your regular expenses, how much money do you have left each month to service a loan repayment?

Lenders call this your net surplus or discretionary income. They take your net income (after tax), subtract your monthly living expenses and any existing debt repayments, and arrive at a figure they consider available for a new loan. They then apply a buffer on top of that to account for rate changes or unexpected expenses.

The loan amount they are willing to approve is the figure that the remaining surplus can comfortably service, at the interest rate they offer you, over the loan term you choose.

INCOME: WHAT COUNTS AND WHAT DOES NOT

Most lenders will consider the following as acceptable income:

•        PAYG salary or wages (full-time and part-time)

•        Self-employment income supported by tax returns or business bank statements

•        Rental income (usually at a discounted rate, often 70 to 80 per cent of the actual amount)

•        Government payments and pensions (varies by lender)

•        Regular investment income

Casual income and overtime are treated cautiously. Some lenders require two years of evidence before including them. Probationary employment can also affect approval, though not all lenders apply this restriction.

If you are self-employed or working under an ABN, you may still qualify. Our guide on ABN loans and borrowing without tax returns explains what lenders accept instead.

THE ROLE OF YOUR CREDIT SCORE

Your credit score influences your borrowing capacity in two ways. First, it affects whether a lender will approve you at all. Second, it affects the interest rate they offer you, which directly changes how much you can borrow for a given repayment amount.

A borrower with a strong credit score might qualify for a rate of 7.00% p.a. (comparison rate 7.25% p.a.). A borrower with a weaker score might be offered 11.00% p.a. (comparison rate 11.45% p.a.). At the same monthly repayment, the lower rate supports a significantly higher loan amount.

If you are concerned about protecting your credit score while comparing lenders, see our article on soft credit checks and how they work. Finwave uses a soft check in our pre-approval process, which does not affect your score.

HOW LIVING EXPENSES AFFECT YOUR LOAN

Lenders use the higher of your declared living expenses or a benchmark figure (commonly the Household Expenditure Measure, or HEM). If your declared expenses are lower than the benchmark, the lender will use the benchmark anyway.

This means two borrowers with the same income but different household sizes or lifestyles can be approved for very different loan amounts. A single person with low rent and no dependants will generally qualify for more than a family with a mortgage, school fees, and multiple car repayments.

INDICATIVE BORROWING CAPACITY EXAMPLES

The figures below are indicative only and are provided for planning purposes. Actual approved amounts will vary based on your credit profile, the lender, and your full financial position. Rates from 6.99% p.a. (comparison rate 7.24% p.a.) apply subject to lender assessment and approval.

Net income (monthly)	Low expenses	Medium expenses	High expenses
$4,000	$18,000 to $22,000	$14,000 to $18,000	$10,000 to $14,000
$6,000	$28,000 to $34,000	$22,000 to $28,000	$16,000 to $22,000
$8,000	$38,000 to $46,000	$30,000 to $38,000	$22,000 to $30,000
$10,000	$48,000 to $58,000	$38,000 to $48,000	$28,000 to $38,000

Figures are indicative only. Based on a 5-year loan term at 8.5% p.a. (comparison rate 8.85% p.a.). Individual results will vary. Credit subject to approval and lender criteria.

DEPOSIT AND LOAN TERM: WHAT CHANGES?

Deposit

A deposit reduces the amount you need to borrow. It does not directly increase the maximum loan a lender will approve, but it lowers your repayment for the same vehicle price, which can make approval easier if your borrowing capacity is borderline.

Loan term

A longer loan term spreads the repayments over more months, which increases the loan amount your monthly surplus can support. However, you pay more interest overall on a longer term. Most car loans run from one to seven years. Finwave brokers can help you model the difference between term lengths before you apply.

FREQUENTLY ASKED QUESTIONS

How do lenders calculate how much I can borrow for a car loan?

Lenders assess your net income, monthly living expenses, existing debt commitments, and credit history. They calculate what is left over after your expenses and use that surplus to determine a comfortable repayment amount. The loan term and interest rate then determine the maximum loan amount that repayment figure can support.

Does my credit score affect how much I can borrow?

Yes. A strong credit score can qualify you for a lower interest rate, which increases your borrowing capacity for the same repayment amount. A lower score may result in a higher rate or a reduced loan limit. Lenders use your credit score alongside income and expenses, not as the only factor.

Will a larger deposit increase my borrowing capacity?

A larger deposit reduces the amount you need to borrow, which lowers your repayments. It can also improve your approval chances if your borrowing capacity is borderline. However, it does not directly increase the maximum amount a lender will approve. That is determined by your income and expenses.

Does the loan term affect how much I can borrow?

Yes. A longer loan term spreads repayments over more months, which can increase the total amount you are able to borrow for a given monthly repayment. However, a longer term means more interest paid overall. Most car loans run from one to seven years depending on the lender and vehicle type.

Can Finwave tell me how much I can borrow before I apply?

Yes. Finwave can complete a pre-approval assessment using a soft credit check that does not affect your credit score. This gives you a clear indication of your borrowing capacity and the loan amount you are likely to be approved for before you start shopping for a vehicle.
