Does Car Loan Refinancing Hurt Your Credit Score?

If you’re thinking about refinancing your car loan, it’s normal to wonder whether it will impact your credit score. The short answer is yes—but in most cases, the effect is small and temporary.

What matters more is how you approach refinancing, and whether you’re applying strategically or triggering multiple credit checks unnecessarily.

If you’re new to the process, it can also help to learn how car loan refinancing works before deciding whether it’s the right move.

How Credit Scores Work in Australia

Your credit score reflects how you’ve managed credit over time. In Australia, lenders use Comprehensive Credit Reporting (CCR), which means your score is influenced not just by applications, but by your ongoing repayment behaviour.

Some of the key factors include:

• Whether you make repayments on time
• How often you apply for credit
• The types of loans you hold
• Your overall level of debt

Because repayment history is such a strong factor under CCR, consistently meeting your obligations can have a bigger long-term impact than a single credit enquiry.

Does Refinancing a Car Loan Affect Your Credit Score?

Refinancing can affect your credit score in two key ways:

A hard credit enquiry

When you formally apply for a new loan, the lender performs a hard credit check. This can cause a small, temporary drop in your score.

A new loan account

Your refinanced loan replaces your existing one, which means your credit file is updated with a new account and the old one is closed.

In most cases, these changes have a minor short-term impact, especially if your overall credit behaviour is strong.

If you’re considering refinancing, you can also check your eligibility online to see what options may be available before submitting a full application.

The Difference Between Soft and Hard Credit Checks

Understanding this difference is key to protecting your credit score.

Soft credit check

A soft check allows you to see your eligibility without affecting your credit score. It’s typically used for pre-checks or initial assessments.

Hard credit check

A hard check occurs when you formally apply for a loan and is recorded on your credit file.

Why this matters when refinancing

If you apply with multiple lenders individually, each application may trigger a separate hard enquiry.

With Ausloans, your profile is assessed using a Zink-powered pre-check, allowing you to explore multiple lender options upfront with no impact on your credit score. This reduces the need to submit multiple applications just to compare outcomes.

This is why many borrowers choose to refinance their car loan through a single platform, rather than applying with multiple lenders individually.

Can Refinancing Improve Your Credit Score?

In some cases, refinancing can actually help strengthen your credit position over time.

More manageable repayments

If refinancing reduces your repayment pressure, it becomes easier to stay consistent—which is one of the most important factors in your credit score.

A better-structured loan

Moving to a loan that better suits your situation can reduce financial strain and support stronger repayment behaviour.

When Refinancing Might Have a Bigger Impact

While the impact is usually small, there are situations where it can be more noticeable:

Multiple applications in a short period

Submitting several loan applications at once can lead to multiple hard enquiries.

Missed or late repayments

If repayments are missed—before or after refinancing—this can have a much larger negative effect than the refinance itself.

Refinancing too frequently

Repeatedly switching loans in a short timeframe may raise concerns for lenders reviewing your credit history.

How to Protect Your Credit Score When Refinancing

A few simple steps can help minimise any impact:

• Use a pre-check before submitting a full application
• Avoid applying with multiple lenders individually
• Keep your repayments up to date
• Only refinance if it improves your financial position
  

   

Timing can also play a role, so it’s worth understanding how soon you can refinance a car loan based on your situation.

A Smarter Way to Compare Refinance Options

One of the biggest risks to your credit score isn’t refinancing itself—it’s how you shop around.

Applying with multiple lenders separately can lead to unnecessary enquiries. Using a finance aggregator like Ausloans allows you to explore your options in one place before committing.

Through the Zink platform, your profile is assessed across a panel of lenders, helping identify suitable options without triggering multiple hard checks. This gives you a clearer picture of what’s achievable before you decide to proceed.

Final Thoughts: Should You Be Concerned?

Refinancing a car loan can affect your credit score—but in most cases, the impact is small, temporary, and manageable.

What matters most is your overall credit behaviour. If refinancing helps you move to a better loan and maintain consistent repayments, it can support your financial position over time.
