Guide to Car Finance in Australia

There are at least five distinct ways to pay for a car in Australia, and they differ by far more than the interest rate. Ownership, tax treatment, fees, and what happens at the end of the term all change the real cost — and the cheapest option for your neighbour may be the most expensive for you. This guide explains each method in plain English, what it suits, and the numbers to compare before you sign anything.

First, the numbers that actually matter

Before comparing products, fix the four figures that determine the real cost of any car finance:

• Comparison rate, not the headline rate. The headline rate is what is advertised; the comparison rate folds most fees into a single figure so two loans can be compared fairly. A lower headline rate with high fees can be the dearer loan.
• Total cost over your hold period, not the monthly repayment. A low monthly figure can hide a long term, a high price, or a balloon.
• Any balloon or residual. A lump sum owing at the end of the term lowers monthly repayments but is real money you still have to find — see our balloon payment explainer.
• Tax treatment. For business use and for salary-packaged novated leases, tax changes the comparison materially. For private use of a personal loan, it does not.

1. Paying cash

Paying outright is the simplest option: no interest, no fees, no lender, and you own the car immediately. The catch is the opportunity cost — the return that money could have earned (or the interest it could have saved on a mortgage) had you not spent it on a depreciating asset.

Cash usually wins when finance rates are high relative to what you could earn on the money, or when being debt-free has real value to you. It is less clear-cut when you could borrow cheaply and invest the difference at a higher return. We work through this trade-off in cash vs finance.

2. Secured personal car loan

A secured car loan is the most common way private buyers finance a vehicle. The car itself is the security, which usually means a lower rate than an unsecured personal loan. You borrow the purchase price (less any deposit), repay it in fixed instalments over a set term, and own the car once the loan is repaid.

• Secured vs unsecured: securing the loan against the car typically lowers the rate but means the lender can repossess if you default.
• Fixed vs variable rate: fixed gives repayment certainty; variable can move with the market.
• Term length: a longer term lowers the monthly repayment but increases total interest paid.
• Deposit: a larger deposit reduces the amount financed and the interest you pay.

The key skill here is comparing offers properly — our guide on how to compare car loan interest rates walks through doing it on a like-for-like basis.

3. Dealer finance

Dealer finance is arranged at the point of sale, which makes it convenient — and convenience has a price. The loan is often provided by a third-party lender via the dealer, and frequently structured with a balloon payment (a large amount owing at the end of the term) to keep the monthly repayment attractive.

Dealer finance is not automatically a bad deal, but it deserves the same scrutiny as any loan: check the comparison rate, the balloon, the total cost over the term, and any early-exit fees. The convenience can be worth it if the numbers stack up against a personal loan — our dealer finance vs personal loan guide compares them directly.

4. Chattel mortgage and finance lease (business)

If the car is used predominantly for business, a chattel mortgage or finance lease can offer tax advantages a private loan cannot. Under a chattel mortgage you own the vehicle and the financier takes a mortgage over it; businesses registered for GST may be able to claim the GST in the purchase price and claim depreciation and interest, subject to the rules. A finance lease works differently — the financier owns the vehicle and leases it to the business.

These products are governed by specific tax rules and depend on your business structure and the proportion of business use. Sole traders have particular considerations — see our sole trader car finance guide — and you should confirm the treatment with your accountant before deciding.

5. Novated lease (employees)

A novated lease is a three-way arrangement between you, your employer, and a leasing company. Your employer deducts the lease and running costs from your pre-tax salary, reducing your taxable income, which can lower the after-tax cost of running the car. The package typically bundles finance, fuel or charging, insurance, registration, and servicing into a single deduction.

Two things make or break a novated lease:

• Fringe Benefits Tax (FBT). For most cars, FBT applies and is usually offset by a post-tax employee contribution. For eligible electric vehicles priced under the relevant threshold, an FBT exemption can apply, which substantially improves the numbers. The rules here are changing — see the EV FBT exemption and the 2026 Budget changes.
• The residual value. A novated lease has a residual (a set amount owing at the end) determined by the ATO based on the term. Understanding it before you start matters — see novated lease end of term.

A novated lease is generally most beneficial for employees on higher marginal tax rates and for eligible EVs. It is not usually suitable for the self-employed. Learning to read the quote is essential — our how to read a novated lease quote guide breaks one down line by line, and novated lease vs personal loan compares it against a straight loan.

How to compare them fairly

Different finance products are quoted in different ways, which makes direct comparison hard unless you normalise them. To compare like for like:

1. Use the true total cost over your hold period as the headline number — it captures interest, fees, tax effects, balloon or residual, and the car's exit value.
2. Convert that to an effective monthly cost (total cost divided by the months you will own the car) so structures with different term lengths are comparable.
3. Separate finance cost from running cost so a bundled product (like a novated lease) is not unfairly flattered or penalised against an unbundled one.
4. For business and novated options, fold in the tax effect, because that is the whole point of those structures.

This is exactly what the Veercal calculator does — our companion guide how to make an informed decision on car finance walks through using those numbers to decide.

Which suits which situation

These are starting points, not recommendations — the right answer always depends on your specific numbers, which is why modelling them matters more than rules of thumb.
