How Your Credit Score Affects Your Car Loan in Australia

When you apply for a car loan in Australia, lenders look at many factors to decide whether to approve your application and what interest rate to offer. Among these factors, your credit score stands out as perhaps the most influential. This single number, derived from your credit history, can mean the difference between approval and rejection, and between a competitive rate and an expensive one. Understanding how credit scores work and affect car loans empowers you to take control of your financial destiny.

Understanding Credit Scores in Australia

In Australia, credit scores are calculated by credit reporting agencies, primarily Equifax, Experian, and illion. Each agency uses its own scoring model, so your score may differ between agencies. Generally, scores range from 0 to either 1000 or 1200 depending on the agency, with higher numbers indicating better creditworthiness.

Credit scores are calculated from information in your credit report, including your repayment history on credit accounts, the types and amounts of credit you hold, how long you have had credit, and recent credit applications. Negative events like defaults, court judgments, or bankruptcies significantly damage your score and can remain on your report for years.

Unlike some countries, Australia uses comprehensive credit reporting, meaning both positive and negative information appears on your report. Regular on-time payments improve your score over time, while missed payments hurt it. This system rewards consistent good behaviour and penalises poor credit management.

How Lenders Use Your Credit Score

When you apply for a car loan, lenders request your credit report and score as part of their assessment. The score provides a quick summary of your creditworthiness, helping them categorise applications efficiently. Beyond the score itself, lenders also review the detailed information in your report.

Different lenders have different risk appetites. Some specialise in prime borrowers with excellent credit and offer the lowest rates to this group. Others focus on subprime lending, accepting borrowers with damaged credit but charging higher rates to compensate for increased risk. Understanding where you fit helps you target appropriate lenders.

Lenders typically have score thresholds that trigger different outcomes. Above a certain score, applications receive streamlined approval with the best rates. Below that but above another threshold, applications require more scrutiny and may receive higher rates. Below the lower threshold, applications may be declined or referred to specialised subprime products.

The Rate Impact of Different Credit Scores

The difference in interest rates between excellent and poor credit can be dramatic. While specific rate tiers vary by lender and market conditions, the pattern is consistent: better credit equals lower rates.

A borrower with excellent credit, typically a score above 800, might access rates from 5% to 7% for a secured car loan. Someone with good credit in the 700-800 range might see rates from 7% to 10%. Fair credit in the 500-700 range often results in rates from 10% to 15%, while poor credit below 500 can mean rates above 15% if approval is granted at all.

To illustrate the cost difference, consider a $25,000 loan over five years. At 6%, you would pay approximately $3,900 in total interest. At 12%, that interest climbs to around $8,400. The credit score difference costs over $4,500 on this single loan. Use our calculator to see how different rates affect your specific loan amount.

What Hurts Your Credit Score

Several factors can damage your credit score and affect your car loan options. Understanding these helps you avoid pitfalls and, if damage has occurred, explains why your score might be lower than expected.

Payment defaults are the most damaging entries on a credit report. A default typically occurs when a debt remains unpaid 60 days or more past due and the creditor has been unable to reach you. Defaults stay on your report for five years and significantly impact your score, often making prime lending inaccessible.

Multiple credit applications in a short period raise red flags. Each application creates an inquiry on your report, and numerous inquiries suggest financial stress or desperation. If you are shopping for rates, try to do so within a 14-30 day window when inquiries for the same loan type are typically treated as one.

High credit utilisation, meaning using most of your available credit, signals risk. If your credit card is consistently near its limit, lenders worry about your ability to manage additional debt. Keeping utilisation below 30% of your limit demonstrates restraint.

Improving Your Credit Score Before Applying

If your credit score is less than ideal, taking time to improve it before applying for a car loan can yield substantial benefits. Even modest improvements can push you into a better rate tier, saving significant money over your loan term.

Start by obtaining your credit report and reviewing it for errors. Incorrect information is surprisingly common and can unfairly lower your score. Dispute any errors through the credit reporting agency's formal process. Corrections can improve your score relatively quickly.

Pay all bills on time, every time. Your payment history is the single largest factor in your score calculation. Setting up automatic payments or reminders ensures you never miss due dates. Even a few months of consistent on-time payments can begin improving your score.

Reduce credit card balances and avoid applying for new credit in the months before your car loan application. Lower balances improve your utilisation ratio, and fewer inquiries present a less risky profile. Patience during this period pays off in better loan terms.

Options for Borrowers with Poor Credit

If your credit score is damaged, you still have options for car financing, though they come with trade-offs. Understanding these options helps you make the best of a difficult situation.

Specialist subprime lenders work with borrowers who cannot qualify for mainstream loans. These lenders accept higher risk but charge higher interest rates accordingly. While expensive, they provide a path to vehicle ownership and, if managed well, an opportunity to rebuild credit through consistent payments.

Secured loans where the car serves as collateral may be available even with poor credit because the vehicle provides lender security. You might need a larger deposit to offset the credit risk, but secured lending rates are typically lower than unsecured alternatives for the same borrower profile.

A guarantor loan involves someone with better credit agreeing to guarantee your loan. This person becomes responsible if you default, which reduces lender risk and can secure better terms. However, this arrangement puts the guarantor at financial risk and should be approached carefully.

Rebuilding Credit Through Your Car Loan

If you obtain a car loan with less-than-perfect credit, managing it well provides an opportunity to rebuild. Regular on-time payments are reported to credit agencies and gradually improve your score. After 12-24 months of positive history, your credit position should be significantly better.

This improved credit opens doors to refinancing. Once your score has improved, you may qualify for lower rates than your original loan carries. Refinancing at a better rate reduces your ongoing costs and saves money for the remainder of your loan term.

The key is treating your car loan as a credit-building tool, not just a necessary evil. Make every payment on time, keep other credit accounts in good standing, and your score will improve. Future borrowing, including your next car or even a home loan, will benefit from this effort.

Taking Control of Your Credit Future

Your credit score is not fixed. Through deliberate action, you can improve it over time and access better financial products. Understanding how lenders view credit scores helps you present the strongest possible application and secure the best available terms.
