The short answer: there is no single best car finance option in Australia. The main ways to finance a car are a secured car loan, an unsecured personal loan, dealer finance, a novated lease, and a chattel mortgage for business use. For most people buying a car for personal use, a secured car loan usually comes with the lowest interest rates, because the car backs the loan. But the option that genuinely fits you depends on a few things: whether the car is for personal or business use, whether your employer offers salary packaging, and how your own situation stacks up. And the single biggest money decision most buyers get wrong has nothing to do with the lender. It is comparing the weekly repayment instead of the total cost. More on that below.
Noma Finance compares car finance options across a panel of around 25 lenders, so you see the total cost of the finance before you sign, not just the weekly repayment.
I worked at a car dealership before I became a broker, so I have sat on the other side of the finance desk. This is the explanation I wish every buyer walked in with.
Key takeaways
There are five common ways to finance a car in Australia. Each one suits a different kind of buyer, so it helps to know what you are choosing between before you start.
A secured car loan and an unsecured personal loan are the two most common options for personal buyers. Dealer finance is the loan arranged for you at the dealership. A novated lease is a salary packaging arrangement set up through your employer. A chattel mortgage is a business finance product for people buying a vehicle mainly for work. Here is how each one actually works, and where it tends to fall down.
Here is how the five options compare at a glance, before we get into the detail of each.
A secured car loan is usually the lower-cost option for someone buying a car for personal use. The car you are buying is used as security for the loan, which lowers the lender’s risk. According to ASIC’s Moneysmart, a secured loan usually carries a lower interest rate than an unsecured one for this reason, and it can mean a longer term and a higher borrowing limit. You own the car from day one, and the lender records their interest on the Personal Property Securities Register, the national government register of security interests, until the loan is paid off.
The trade-off is that the car is security. Moneysmart notes that if you fall seriously behind on repayments, the credit provider has the right to sell the car to recover what they are owed. Lenders also tend to have rules about the age of the car, so a very old or high-kilometre vehicle may not qualify. It tends to suit buyers with a reasonable credit history who are buying a newer or near-new car. If you are getting your first car loan, our guide on how to get a car loan in Australia walks through the steps.
An unsecured personal loan is worth considering when a secured loan does not fit, for example if you are buying privately or buying an older car. You are not putting the car up as security, so there is no asset for the lender to repossess if things go wrong, and the loan is often quicker to arrange with less paperwork.
The downside is usually the rate. Because the lender has no security, Moneysmart notes that unsecured loans usually have higher interest rates than secured ones. Over a five-year term that gap can add up, so it is worth weighing the convenience against the cost. Moneysmart also points out that if you do not repay an unsecured loan, the lender can take legal action to recover the money.
Dealer finance is the loan offered to you at the dealership, arranged on the spot when you buy the car. Its appeal is convenience. You can sort the car and the finance in one visit, which is why a lot of people sign up for it.
There are two things worth understanding before you do. First, it is usually a single finance offer, not a comparison across lenders, so you are not seeing what else is available. Second, the cost can vary a lot depending on who arranged the loan. ASIC’s Moneysmart points out that finance arranged at the dealership can involve fees to several parties, including a lender and sometimes a broker, so it is worth asking who is involved and what fees apply before you sign. In its June 2026 review of car loans, ASIC looked at more than 350,000 loans across eight providers and found the total cost could vary widely, with loans often carrying two separate establishment fees. In one case a customer paid over $9,000 in fees on a car loan of about $49,000. None of that makes dealer finance a bad choice on its own, but it is a strong reason to compare. ASIC’s Moneysmart suggests comparing loans before you visit a car dealer, so you know what a fair deal looks like before you are in the room. Getting finance pre-approved before you walk in also lets you treat the car price and the finance as two separate conversations.
A novated lease can be tax-effective if you are employed and your employer offers salary packaging. It is a three-way arrangement between you, your employer, and a finance provider. Your employer makes the lease payments from your pre-tax salary, which can reduce your taxable income, and a fully maintained lease can bundle running costs like fuel, servicing, registration and insurance into one payment. Eligible battery electric vehicles can be especially worth pricing up here. We go deeper in our guide on whether a novated lease on an electric car is worth it. The ATO currently provides a fringe benefits tax exemption for eligible zero or low emissions electric cars that meet its conditions, which include the car being first held and used on or after 1 July 2022 and being under the luxury car tax threshold, and benefits provided under a salary packaging arrangement can be included.
Two points the ATO sets out are worth knowing. Plug-in hybrid vehicles have not been eligible for this exemption since 1 April 2025. And the full exemption is being wound back over time: the government has announced changes that begin on 1 April 2027 and reduce the concession further from 1 April 2029, with arrangements already in place expected to be preserved. The exemption can lower the cost of an eligible EV, but because eligibility, timing and any saving depend on your circumstances and the current rules, and because the detail is still being settled, check the ATO’s guidance and speak with a licensed tax adviser before relying on it.
The trade-offs matter. You do not own the car during the lease, and there is usually a residual value to pay at the end if you want to keep it. The arrangement is tied to your job, so if you change employers the lease may come back to you. There can also be limits on kilometres and wear and tear. Because the tax treatment depends on your personal circumstances, talk to a licensed tax adviser before deciding whether a novated lease stacks up for you.
A chattel mortgage is a business finance product, designed for sole traders and companies buying a vehicle that is mainly used for work. You own the vehicle from day one and the lender holds a mortgage over it until the loan is repaid. For eligible businesses there can be tax advantages, which may include claiming GST and deductions for interest and depreciation, and many buyers add a balloon payment to lower their regular repayments. Depending on the vehicle and timing, the instant asset write-off for a work vehicle may also be relevant. The exact treatment depends on your business, how the vehicle is used, and current ATO rules.
Two things to keep in mind. Because a chattel mortgage is business lending, it is generally treated differently from a personal car loan and may sit outside some of the consumer credit protections that apply to personal loans. And the tax outcomes are not automatic. This is squarely an area to confirm with your accountant or tax adviser and to check against the ATO’s guidance, rather than assume from a general article.
The best car finance option is the one that matches three things: what the car is for, how you are employed, and what you want at the end. Work through those and the field narrows quickly.
If the car is for personal use, you are usually choosing between a secured car loan and an unsecured personal loan, and a secured loan tends to win on rate if the car qualifies. If your employer offers salary packaging and you want a newer car or an EV, a novated lease is worth pricing up alongside a loan. If the car is mainly for business, a chattel mortgage and the tax questions that come with it move to the front. The point is not to find the option with the lowest weekly repayment. It is to find the structure that fits your life and costs you the least overall.
Two smaller choices also affect the cost. A fixed rate keeps your repayment the same for the whole term, while a variable rate can move up or down. Moneysmart notes variable car loans often have no early exit fee, which can suit you if you plan to make extra repayments.
The weekly repayment tells you what fits your budget. It does not tell you what the loan actually costs. Two loans with the same weekly repayment can cost very different amounts once you add up the full term, the interest, and the fees. That is where the comparison rate comes in. ASIC’s Moneysmart defines a comparison rate as a single figure that helps you work out the true cost of a loan, including the interest rate and most fees and charges. For car loans, Moneysmart notes the lender must give you the comparison rate, which makes it the cleanest way to compare one loan against another. Just compare the same loan amount and term when you do. For current market context, see our guide to car loan interest rates in Australia.
Here is an illustrative example, using round numbers to show the idea rather than any real offer. Say you borrow $35,000 over five years. A loan advertised at a lower weekly repayment but stretched over a longer term, or carrying higher fees, can quietly cost you more in total than one with a slightly higher repayment over a shorter term. Always check the total amount repayable and the comparison rate, not just the number per week. (Illustrative figures only. A comparison rate is true only for the example given, and different amounts or terms produce different comparison rates.)
A balloon payment is a lump sum left owing at the end of the loan, after all your regular repayments are done. Setting one means your weekly or monthly repayments are lower, which can help cash flow. The catch, as Moneysmart explains, is that you still repay that lump sum with interest, so the total cost of the loan is generally higher. A balloon can make sense, particularly for some business buyers managing cash flow, and it can hurt if you have not planned for the final payment. Moneysmart’s advice is to be confident you will have the money to pay it when it falls due. Like the rest of this, it comes down to your situation.
A balloon payment is not the same as a guaranteed future value, or GFV. With a GFV the lender agrees a set value for the car at the end of the term, and you can return it for that value, keep it, or trade it in, usually subject to conditions like a kilometre limit and fair wear and tear. A balloon is simply a lump sum you still owe. Moneysmart covers both, and the right one, if any, depends on your plans for the car.
Both can work. Going direct to a bank or lender is straightforward if you already know what you want. A broker compares options across a panel of lenders rather than a single bank’s products, handles the application and paperwork, and is generally paid by the lender rather than by you. Where a broker earns their keep is when your situation is not cookie-cutter, or when you simply do not have time to compare the market yourself. We cover the trade-offs in detail in our guide on a finance broker compared with a bank.
That is the part of the job I love, working out which lender actually fits someone, then explaining the options so they can make the call themselves. No pressure, no jargon, no judgment.

For a first car bought for personal use, a secured car loan is usually the most cost-effective option if the car qualifies, because it tends to carry a lower interest rate than an unsecured loan. The right answer still depends on the car, your income, and your credit history.
A formal credit application is recorded on your credit file, and Moneysmart notes that several applications in a short space of time can affect how lenders see you. Many brokers and lenders can give you an indication of your options using a soft check before you formally apply, which does not affect your score.
Yes. Secured car loans are available for many used cars, though lenders often have limits on the age of the vehicle at the end of the loan term. For older cars or private sales, an unsecured personal loan is sometimes the more practical route.
A comparison rate combines the interest rate with most fees and charges into a single percentage, so you can compare the true cost of different loans rather than just the advertised interest rate.
It helps. Walking in with finance pre-approved means you know your budget and your rate, and you can treat the car price and the finance as two separate negotiations rather than one bundled deal.
There is no single best way, because it depends on how the car will be used and how you are employed. For most personal buyers a secured car loan is the lower-cost option if the car qualifies. If your employer offers salary packaging, a novated lease can be worth pricing up, and for a work vehicle a chattel mortgage brings its own tax questions. Comparing the total cost across lenders, rather than the weekly repayment, is the part that matters most.
It depends on the car and your situation. A secured car loan usually has a lower interest rate because the car is used as security, so it often suits newer or near-new cars. An unsecured personal loan does not put the car at risk of repossession and can suit private sales or older cars, but the rate is usually higher. Comparing the comparison rate on the same amount and term is the cleanest way to weigh them up.
Lenders look at more than your income. They weigh up your regular expenses and existing repayments against what you earn, often described as your debt-to-income position, along with your deposit, your credit history and the car itself. Two people on the same salary can be offered very different amounts. A broker can give you an indication before you formally apply.
