Buying a car is exciting. The finance paperwork? Less so. Most Australians sign their car loan without fully understanding the terms — and that can cost thousands over the life of the loan. Here are seven things worth knowing before you put pen to paper.
1. The Comparison Rate Is the One That Matters
Lenders advertise headline interest rates because they look attractive. A 5.99% headline rate might actually cost you closer to 8% once fees are factored in. The comparison rate rolls the interest rate and most fees into a single annual figure, giving you a true picture of the loan's cost.
Always compare comparison rates — not headline rates — when evaluating lenders side by side. Under Australian law, lenders must display a comparison rate alongside any advertised rate. Look for it.
Note: Comparison rates are calculated on a standard $30,000 loan over five years. Your actual rate may differ based on loan amount and term.
2. Balloon Payments Can Trap You
A balloon payment (sometimes called a residual) reduces your monthly repayments by deferring a large lump sum to the end of the loan term. On paper it sounds appealing — lower repayments today. In practice, many borrowers arrive at the end of the term unable to pay the balloon and are forced to refinance, often at a worse rate.
If a balloon is part of your loan structure, make sure you have a clear plan for how you'll fund it. Options include saving toward it monthly, refinancing before it falls due, or selling the vehicle.
3. Secured vs Unsecured — Know the Difference
Most car loans are secured — the vehicle acts as collateral. This typically means lower interest rates because the lender has security. If you default, the lender can repossess the car.
An unsecured personal loan for a vehicle carries higher rates but gives you more flexibility — particularly useful for older vehicles that don't meet a lender's security criteria (many lenders won't secure a loan against a car older than 10–12 years).
If you're buying a newer vehicle, a secured loan almost always offers a better rate. Use ClariFi's loan repayment calculator to model the cost difference.
4. Every Credit Application Leaves a Mark
When you apply for credit, the lender typically performs a hard enquiry on your credit file. Multiple hard enquiries in a short period signal to lenders that you're in financial stress — even if you were simply shopping around.
The smarter approach is to use a broker or comparison service (like ClariFi) that performs a soft check upfront. Soft checks are invisible to lenders and don't affect your credit score. You only trigger a hard enquiry when you formally proceed with a lender you've chosen.
5. Dealer Finance Is Rarely the Best Deal
The finance desk at a car dealership is a profit centre. Dealers earn commission on finance products they place, which creates an incentive to push you toward a higher-rate product or add-ons you don't need (extended warranties, gap insurance, payment protection).
This doesn't mean dealer finance is always bad — occasionally dealers run manufacturer-subsidised rate promotions that are genuinely competitive. But you should always check what an independent broker or lender can offer before agreeing to dealer finance.
6. A Broker Can Access Rates You Can't Find Directly
Finance brokers like ClariFi have accreditation with dozens of lenders and access to rates not available to retail customers. Because lenders compete for a broker's loan book, they often offer sharper pricing through the broker channel than through their own branch or website.
More importantly, a good broker does the comparison work for you — presenting the most competitive options for your specific profile rather than requiring you to research 20 lenders independently.

7. Know When to Refinance
If you took out a car loan two or more years ago at a higher rate, it may be worth refinancing — especially if your credit score has improved or market rates have dropped. Refinancing costs (discharge fee, new application fee) are typically modest compared to the interest savings on a lower rate over the remaining term.
Use the loan repayment calculator to estimate your current repayments and model what a rate reduction would save you monthly and over the remaining term.
