Refinancing a Car Loan: When It Makes Sense

You can refinance a car loan by replacing your current loan with a new one at a lower interest rate, a shorter term, or both. If your credit score has improved or rates have dropped since you took out the original loan, refinancing could save you thousands. On a $20,000 balance, switching from 12% to 7.5% saves roughly $2,700 in interest over the remaining term. Here is how to work out whether it is worth it.

Why car loan refinancing is worth considering in 2026

Many Australians took out car loans at dealer rates of 10% to 14% during 2023 and 2024, when lender competition was tighter and vehicle prices were peaking. Since then, competitive secured car loan rates have come down to as low as 5.09% for strong applicants (Savings.com.au, 2026 comparison). That gap between what people are paying and what is available today means refinancing could deliver meaningful savings, particularly if your credit profile has strengthened since the original loan.

How car loan refinancing works

Refinancing replaces your existing car loan with a new one from a different lender (or sometimes the same lender). The new lender pays out your old loan, the PPSR security interest transfers to the new lender, and you start making repayments on the new loan at the new rate and term.

The process typically takes 2 to 5 business days once approved. Your car's ownership does not change. The only thing that changes is which lender holds the security interest on the PPSR.

Step-by-step process

1. Check your current loan details. Find your remaining balance, current interest rate, remaining term, and any exit or early termination fees. These are on your latest statement or available from your lender.

2. Check your car's value. Use RedBook or Glass's Guide to estimate the current market value. You need the car to be worth more than your remaining balance (positive equity) for a straightforward refinance.

3. Compare new rates. Look at what rates you could qualify for based on your current credit score and the car's age. A finance broker can do this with a single application across multiple lenders.

4. Calculate the breakeven. Add up any exit fees from your current lender plus the new lender's establishment fee and PPSR transfer ($6.30). Compare this total cost against the interest you will save over the remaining term. If the savings exceed the fees, refinancing makes sense.

5. Apply and settle. The new lender pays out the old loan, registers their security interest on the PPSR, and you begin repayments at the new rate.

When refinancing saves you money

Not every refinance is worth the effort. Here are the two most common scenarios where it pays off.

Scenario 1: dealer rate rescue

You bought a car through a dealer who arranged finance at a higher rate. This is one of the most common refinance opportunities in Australia.

Subject to lender approval, terms, and conditions apply. Rates are illustrative.

Scenario 2: rate-drop refinance

Your credit score has improved since you took out the loan, or market rates have dropped.

The saving is smaller here because the rate gap is narrower and the remaining term is shorter. This is the breakeven calculation in action: a $362 net saving over three years is still worthwhile, but only just.

When refinancing is not worth it

Refinancing does not always save money. Skip it if the remaining term on your loan is under 12 months (the fees will eat most of the interest saving), your car is in negative equity (the loan balance exceeds the car's current value), the rate difference is less than 1.5% and your balance is under $10,000, or the exit fees from your current lender are unusually high.

A useful rule of thumb: if the total fees to switch are more than 50% of the projected interest saving, the refinance is marginal at best.

What you need to refinance

The requirements are similar to applying for a new car loan. You will need 100 points of ID, proof of income, your current loan details (statement showing balance, rate, and remaining term), and the car's registration and odometer reading.

The car must still meet the new lender's age and condition requirements. Most lenders require the vehicle to be under 12 to 15 years old at the end of the new loan term. If your car is already 10 years old and you want a five-year term, options narrow.

Your credit score matters. If your score has dropped since the original loan (for example, through missed payments or new defaults), you may not qualify for a better rate. Check your credit report for free through Equifax, Experian, or illion before applying.

Should you refinance? Decision checklist

If you answered yes to four or more of these, refinancing is likely worthwhile. Two or fewer, it is probably better to stay on your current loan and reassess in six months.

Costs and fees to watch for

Exit fees from your current lender. Some lenders charge an early termination fee of $0 to $500. Fixed-rate loans are more likely to carry break costs. Check your loan contract or call your lender.

Establishment fee on the new loan. The new lender may charge a one-off fee of $0 to $400. Some lenders waive this for refinance applications.

PPSR transfer. The new lender registers their security interest on the PPSR. The registration fee is $6.30. This is a minor cost but worth noting for completeness.

Monthly account fees. Some car loans carry a $5 to $15 monthly account fee. If your current loan has no monthly fee and the new one does, factor this into the breakeven.
