What Is a Credit Score and Why Does It Matter for Car Finance?

Your credit score is a number that summarises how reliably you have managed credit in the past. When you apply for a car loan, it is one of the first things a lender checks.

In Australia, credit scores are maintained by three bureaux: Equifax, Experian, and illion. Each bureau holds its own file and calculates its own score, so your number can vary slightly depending on which bureau a lender uses. The scoring ranges are also slightly different across bureaux, though the underlying logic is the same.

What goes into your score:

• Your history of repaying loans, credit cards, and bills on time
• The number of credit applications you have made (each lender enquiry is recorded)
• Any defaults, judgements, or bankruptcies on your file
• The age and variety of your credit accounts
• How much of your available credit you are currently using

For car finance, your credit score tells the lender two things: how likely you are to repay, and what rate to price the risk at. A strong score means you are a lower-risk borrower, which translates directly into a lower interest rate. A weak or thin score pushes lenders toward higher rates — or toward specialist lenders who specialise in non-standard applications.

Credit Score Bands Explained

Australian credit scores run from 0 to 1,200 (Equifax) or 0 to 1,000 (Experian and illion). Lenders typically segment borrowers into bands that determine which products and rates they qualify for.

Here is how the bands generally break down, and what each means in practical car finance terms:

What Credit Score Do Lenders Actually Need?

There is no single magic number. Each lender sets its own internal approval criteria, and those criteria are not publicly advertised. That said, the market has clear patterns that give you a practical guide.

For mainstream lenders (banks, credit unions, major non-bank lenders)

Most mainstream lenders require a minimum score in the 600 to 650 range to consider a car loan application. A score in this band does not guarantee approval — they will still look at your income, employment stability, and existing debts — but it keeps you in the conversation.

For competitive rates

The rates you typically see advertised — the ones in a lender’s marketing material — are generally reserved for borrowers with scores of 700 and above, with stable income and clean repayment histories. If your score is in the average band, you will usually receive an offer, but at a rate higher than the headline figure.

For specialist lenders

Specialist and non-conforming lenders work with borrowers who fall below 600, have defaults on file, or have limited credit history. These lenders price their loans at higher rates to reflect the additional risk, but they provide genuine access to finance for borrowers who would otherwise be turned away.

Getting a Car Loan With Bad Credit

A low credit score does not close every door. It narrows the field, but it does not end the conversation — particularly when you are working with a broker who has access to specialist lenders.

Here is what actually matters when a specialist lender assesses a below-average application:

The nature of the credit event

A paid default from three years ago is treated very differently from an unpaid default that appeared last month. Lenders look at what happened, when it happened, and whether it has been resolved. A single medical bill default on an otherwise clean file is very different from a pattern of missed repayments across multiple accounts.

Current income and stability

If your credit history took a hit but your current income is stable and your bank statements show consistent spending patterns, many specialist lenders will look past the score. Evidence of recovery is as important as the score itself.

The deposit

Putting money down reduces the lender’s exposure. A borrower with a low credit score and a 20% deposit is a meaningfully different risk proposition than the same borrower with no deposit. It is not always possible, but if you have savings available, a deposit can unlock better options.

The vehicle age and type

Specialist lenders are often more cautious about older or high-kilometre vehicles when the borrower’s credit profile is already stretched. A newer vehicle with strong resale value gives the lender better collateral, which can work in your favour.

Other Factors That Affect Your Car Loan Rate

Your credit score is the starting point, not the whole picture. Lenders weigh a combination of factors when making a decision and setting a rate.

Income and employment type

Full-time PAYG employment is the easiest file to assess. Casual, part-time, contract, and self-employed income can all be financed — the documentation requirements are heavier, but the income is still countable. For self-employed applicants, most lenders want two years of tax returns and ATO Notices of Assessment.

Existing debts and liabilities

Your existing financial commitments — a mortgage, credit cards, personal loans, HECS/HELP debt, other car loans — reduce your assessed borrowing capacity. Lenders calculate what you can comfortably repay after your existing obligations are covered.

Loan term

Longer loan terms reduce your monthly repayment but increase the total interest paid over the life of the loan. Some lenders price longer terms at a slightly higher rate. Shorter terms cost less overall but require higher monthly payments.

Vehicle age and kilometres

New cars attract lower rates. A vehicle’s age and odometer reading affect the lender’s collateral risk — a 2024 model with 20,000 km is a safer asset than a 2015 model with 180,000 km. Most mainstream lenders cap the vehicle age they will finance, typically between 12 and 15 years at loan end.

Loan-to-value ratio (LVR)

Borrowing less than the vehicle’s assessed value (putting a deposit in) reduces the lender’s exposure and can improve your rate. It is not required, but it is a lever worth understanding if you have savings available.

How to Check Your Credit Score for Free in Australia

You can access your credit score and report for free through each of the three credit bureaux. Checking your own score does not affect it.

• Equifax — free annual credit report, plus score access via their free membership. The most commonly used bureau by Australian lenders for car finance.
• Experian — free score access via their website. Experian’s scale runs from 0 to 1,000.
• illion — free report access. illion is less commonly used by car finance lenders but worth checking for a complete picture.

It is worth checking all three before applying, for two reasons. First, the information on each file can differ — a lender may have reported a default to one bureau but not another. Second, different lenders use different bureaux, so knowing where your score sits across all three gives you a clearer picture of what each lender sees.

How to Improve Your Credit Score Before Applying

If your score is not where you want it, there are concrete steps that can improve it. The timeline depends on how significant the issues are on your file.

What works within 1 to 3 months

• Pay every bill on time. Payment history is the single biggest factor in your score. Even one missed payment can have a meaningful negative impact. Setting up direct debits for minimum repayments on all accounts removes the risk of forgetting.
• Reduce your credit card balances. Your credit utilisation ratio — how much of your available credit you are using — affects your score. Getting balances below 30% of the limit makes a noticeable difference.
• Do not apply for any new credit. Every formal credit application adds an enquiry to your file. In the months before applying for a car loan, avoid applying for credit cards, buy-now-pay-later accounts, or any other finance product.

What takes longer (6 to 12 months or more)

• Paying off a default. A paid default is viewed more favourably than an unpaid one, but it takes time to show on your file and older defaults carry less weight than recent ones.
• Building a positive repayment history. Consistent on-time repayments over 6 to 12 months build a track record that offsets historical credit events.
• Closing unused credit accounts. Multiple open accounts with high limits can signal risk even if the balances are zero. Closing accounts you genuinely do not use can help, though this is a smaller lever than payment history and utilisation.

Why Using a Broker Protects Your Credit Score

This is one of the most practical reasons to use a broker — and one most borrowers do not think about until after they have already done the damage.

Every time you formally apply for a car loan, the lender runs a credit enquiry. That enquiry is recorded on your file. One or two enquiries in a 12-month window are normal. Four or five in quick succession is a red flag to every lender who checks your file — it signals a borrower who has been declined by multiple lenders, or who is in financial difficulty. It actively reduces your score.

The trap is easy to fall into. You apply online with your bank. They decline or offer a rate that is too high. You try another bank. Same outcome. By the time you find a lender who approves you, your credit file has four enquiry marks on it and your score has dropped by enough to push you into a less favourable rate band.

A broker solves this completely:

• One application. The broker collects your details and documents once.
• One credit enquiry. The broker assesses your profile and identifies the lender most likely to approve you on the best terms. They submit to that lender. One enquiry, not four.
• 80+ lenders assessed without additional enquiries. The broker’s knowledge of which lenders suit which profiles means the selection happens before any credit check is run.

If you are unsure where your credit score sits or what lenders are likely to consider your application, the most practical first step is to speak to a broker before submitting anything. An experienced broker can give you a realistic picture of your options without touching your credit file.
