Refinancing Your Car Loan: When It Makes Sense and How to Do It
March 20, 2026
Refinancing your car loan means replacing your current loan with a new one—typically at a lower interest rate, with better terms, or both. According to the Reserve Bank of Australia, interest rates fluctuate regularly, meaning the rate you locked in when you bought your car may no longer be competitive. This guide explains exactly when refinancing makes financial sense and walks you through the process step-by-step.
Key Takeaways
- Refinancing can reduce your interest rate, lower monthly repayments, or shorten your loan term.
- The best time to refinance is when interest rates drop, your credit score improves, or your financial situation changes.
- Most lenders require at least 6-12 months of payment history before approving a refinance.
- Calculate break-even costs before refinancing—fees must be offset by savings.
- A finance broker like Tow Finance Solutions can compare 40+ lenders to find your best refinancing option.

Overview
This article covers the key situations where refinancing delivers real value, the step-by-step refinancing process, how to calculate whether refinancing saves you money, and common pitfalls to avoid. Whether you’re looking to reduce monthly payments or pay off your car faster, you’ll have a clear action plan by the end.
When Does Refinancing Your Car Loan Make Sense?
The decision to refinance should be based on numbers, not assumptions. Here are the five scenarios where refinancing typically delivers genuine savings.
1. Interest Rates Have Dropped
If market rates have fallen since you took out your original loan, refinancing could lock in a lower rate. Even a 1% reduction on a $30,000 loan over five years can save approximately $800-$1,500 in total interest. The Australian Securities and Investments Commission (ASIC) recommends comparing at least three lenders before committing to any loan product.

2. Your Credit Score Has Improved
Your credit score directly influences the interest rate lenders offer you. If you’ve improved your score since taking out your original loan—by paying bills on time, reducing debt, or correcting errors on your credit report—you may now qualify for significantly better rates.
According to Equifax Australia, a credit score improvement of 50-100 points can shift you into a more favourable lending tier. If you’ve been working on your credit, our article on how to fix a low credit score in 5 steps outlines strategies that may help you qualify for better refinancing terms.
3. Your Financial Situation Has Changed
A salary increase, inheritance, or reduced expenses may mean you can afford higher repayments—allowing you to shorten your loan term and pay less interest overall. Alternatively, if finances are tighter, refinancing to extend your term can lower monthly repayments, though you’ll pay more interest over time.
Understanding how to approach car finance deals with confidence helps you negotiate from a stronger position when refinancing.
4. You Want to Remove or Add a Co-Borrower
Life changes—divorce, separation, or a partner wanting off the loan—often require refinancing. The new loan replaces the old one under different names. This is also relevant for those who originally needed a guarantor but can now qualify independently.
Our guide on the role of guarantors in car and business loans explains how guarantor arrangements work and when they can be removed.
5. Your Current Loan Has Unfavourable Terms
Some loans include features that no longer serve you—high fees, limited repayment flexibility, or balloon payments you’d rather avoid. Refinancing can restructure these terms entirely.
If you’re currently dealing with a balloon payment arrangement, our balloon payments explained article breaks down your options.
When Refinancing Doesn't Make Sense
Refinancing isn’t always the right move. Avoid refinancing in these situations:
- Your loan is nearly paid off. The savings won’t outweigh the fees and effort involved.
- Break costs exceed savings. Some loans charge early exit fees that eliminate any benefit.
- Your car’s value has dropped significantly. Lenders may not refinance if you owe more than the car is worth (negative equity).
- You plan to sell the car soon. Refinancing costs won’t be recovered in time.

How to Refinance Your Car Loan: Step-by-Step
Refinancing follows a straightforward process. Here’s exactly what to do.
Step 1: Review Your Current Loan
Gather your current loan documents and note:
- Outstanding balance
- Current interest rate
- Remaining term
- Any early exit fees or break costs
- Balloon payment (if applicable)
This information forms your baseline for comparison. If you’re unsure how your current loan structure works, our guide on how does car finance work in Australia covers the fundamentals.
Step 2: Check Your Credit Score
Request your free credit report from Equifax, Experian, or illion. Review it for errors—incorrect defaults or outdated information can unfairly lower your score. Dispute any inaccuracies before applying.
Step 3: Calculate Your Break-Even Point
Add up all refinancing costs:
- Application fees (typically $0-$500)
- Early exit fees from your current lender
- New loan establishment fees
Divide total costs by your monthly savings to find how many months until you break even. If you plan to keep the car beyond this point, refinancing makes sense.
Step 4: Compare Lenders
This is where working with a finance broker delivers the most value. Rather than approaching banks individually—which triggers multiple credit enquiries—a broker like Tow Finance Solutions accesses 40+ lenders through a single application, protecting your credit score while finding competitive rates.

Step 5: Apply for Your New Loan
Submit your application with:
- Proof of income (payslips, tax returns)
- Current loan payout figure
- Vehicle details (registration, VIN)
- Identification documents
Approval can take as little as one hour with the right lender. Our article on how long does car finance approval usually take in Australia explains what affects processing times.
Step 6: Settle and Close
Once approved, your new lender pays out your existing loan directly. You’ll receive confirmation when the old loan is closed. Your new repayment schedule begins according to the new loan terms.
What Documents Do You Need to Refinance?
Prepare these documents before applying:
- Current loan contract and payout figure
- Recent payslips (last 2-3)
- Bank statements (last 3 months)
- Driver’s licence and proof of address
- Vehicle registration certificate
- Evidence of insurance
Having documents ready speeds up approval significantly. For first-time borrowers or those new to the process, our guide on navigating the loan application process provides comprehensive preparation tips.
How Much Can You Save by Refinancing?
Actual savings depend on your specific circumstances. Here’s a realistic example:
Original Loan:
- Amount: $35,000
- Interest Rate: 9.5%
- Term: 5 years
- Monthly Repayment: $734
- Total Interest Paid: $9,040
Refinanced Loan:
- Amount: $28,000 (remaining balance)
- Interest Rate: 7.2%
- Term: 4 years
- Monthly Repayment: $673
- Total Interest Paid: $4,304
Potential Saving: $4,736 in interest plus $61 lower monthly repayments.

Secured vs. Unsecured: Does Loan Type Affect Refinancing?
Yes. Secured car loans (where the vehicle acts as collateral) typically offer lower interest rates than unsecured loans. When refinancing, you may have the option to switch between these types depending on your equity and creditworthiness.
Our complete guide to secured vs. unsecured loans explains the differences and helps you decide which structure suits your refinancing goals.
Common Refinancing Mistakes to Avoid
Ignoring Total Loan Cost
A lower monthly repayment doesn’t always mean savings. Extending your term reduces payments but increases total interest. Always compare the total amount repaid, not just monthly figures.
Not Reading the Fine Print
Watch for hidden fees in loan agreements. Establishment fees, monthly account fees, and early repayment penalties can erode savings quickly.
Applying to Multiple Lenders Directly
Each credit application creates an enquiry on your file. Multiple enquiries in a short period can lower your credit score. Using a broker avoids this issue.
Forgetting About Your Car’s Value
Lenders assess the loan-to-value ratio (LVR). If your car has depreciated significantly, you may not qualify for refinancing—or you may need to pay down some principal first.
Refinancing Too Often
Every refinance incurs costs. Refinancing more than once every 2-3 years rarely makes financial sense unless circumstances change dramatically.
Frequently Asked Questions
How soon can I refinance my car loan?
Most lenders require 6-12 months of consistent repayment history before considering a refinance application. Some may approve earlier if your credit profile is strong.
Will refinancing hurt my credit score?
A single refinance application typically causes a minor, temporary dip. Using a broker minimises enquiries. Consistent repayments on your new loan will rebuild your score quickly.
Can I refinance if I have bad credit?
Yes, though options may be limited and rates higher. Specialist lenders work with borrowers who have credit challenges. Improving your score first often delivers better outcomes—see how to boost your loan approval odds in 2025.
What is negative equity and can I still refinance?
Negative equity means you owe more than your car is worth. Refinancing is difficult in this situation, but some lenders offer solutions. Paying down extra principal first may help.
Do I need to refinance with my current lender?
No. You can refinance with any lender. In fact, shopping around typically delivers better rates than loyalty to your current provider.
How long does refinancing take?
With complete documentation, approval can take as little as 1-2 business days. Settlement and payout of your existing loan typically adds another 3-5 business days.
Can I change my loan term when refinancing?
Yes. You can shorten your term to pay off faster (and save interest) or extend it to reduce monthly repayments. Choose based on your financial goals.
Are there fees for paying out my current loan early?
Some loans include early termination fees or break costs. Check your current contract or request a payout figure from your lender, which should include all applicable fees.
