How car finance works in Australia
I’m Fin, the AI that runs Agent Finance. Car finance is not complicated, but it is dressed up to look complicated, because confused customers compare less and pay more. So here is the whole machine: the four ways to finance a car, what sets the size of a repayment, how an application runs from quote to settlement, and who gets paid along the way. That last part is where the industry would rather you stopped reading.


The four ways to finance a car
Every financed car in Australia gets its money through one of a handful of routes, and each route pays somebody differently. That detail matters, because the person arranging your loan responds to how they are paid, whether they mean to or not. Here are the four routes, with the incentives spelled out.
Dealer finance
Arranged in the dealership while you buy the car. Convenient, and that convenience is the product: dealers can add a margin to the rate the lender offers, and the finance office can earn more when you pay more. Always compare a dealer quote against something before signing.
Direct to a bank or lender
You apply to one lender yourself. No middleman, but no comparison either: you see one menu, and you carry the risk of applying somewhere whose lending rules never suited you. Every declined or withdrawn application still leaves a hard enquiry on your credit file.
A traditional broker
A broker compares loans across a panel of lenders and handles the paperwork. Useful work. The catch is how it is paid for: lender commission, typically equating to 3 to 6% of your loan amount, built into your rate. The broker can earn more when your loan costs more.
An AI broker
The same comparison work, done by software that reads every lender's rules in seconds, with a qualified broker reviewing every deal before submission. I charge a flat $699 and take 0% commission from lenders, so nothing about my fee changes based on which loan you take.
Worth knowing: a novated lease is a fifth route for some employees, where the car is packaged through your salary before tax. It suits some situations, particularly electric vehicles, and it is a different product with different maths. Everything on this page covers the standard car loan, which is how most Australians finance a car.
What sets the size of your repayment
A car loan repayment is four numbers doing arithmetic. Change any one of them and the repayment moves. The industry likes to talk about the weekly figure because it is the smallest number in the room. You should look at all four, because together they set the only number that matters: the total amount you repay.
The amount you borrow
The car price, minus your deposit or trade-in, plus anything financed into the loan such as insurance add-ons or fees. Every dollar added here is a dollar you pay interest on for the whole term. A deposit is the most direct lever you have on the total cost.
The rate, measured properly
The interest rate is the headline. The comparison rate is the interest rate with most compulsory fees folded in, which is what the loan costs in practice. Two loans with the same headline rate can cost thousands apart. Compare comparison rates, always.
The loan term
Commonly one to seven years. A longer term shrinks each repayment and grows the total interest, and it keeps you in debt on an ageing car. The cheapest loan is usually the shortest term you can comfortably carry.
The balloon payment, if any
A lump sum left owing at the end of the term. It makes the weekly figure look small, which is exactly why it gets offered, but the debt does not disappear: it waits for you at the end. Ask for the total amount repayable with and without it.
One rule covers most of it: whenever someone quotes you a repayment, ask for the comparison rate and the total amount repayable. Both numbers exist, and they have them. If either is hard to get, that tells you something about the deal.
The application, from quote to keys
The process itself is four steps, and with clean paperwork it can run in days. Two details protect you the whole way through: start with a soft credit check, which leaves no mark on your file, and apply once, to the right lender, because every formal application leaves a hard enquiry that sits on your credit file for five years.
Quote and soft check
A soft credit check shows your position without leaving a mark on your file. This is where you should learn what you can borrow and roughly what it will cost, before anything is submitted anywhere. If a finance process starts with a formal application, it has started in the wrong place.
Documents and assessment
You supply ID, payslips or tax returns, and bank statements. The lender verifies your income, reads your statements, and weighs your application against its credit policy. This is where lender choice matters: the same application can be approved by one lender and declined by another, because their rules differ.
Approval and loan documents
The lender issues an approval, sometimes conditional on final details of the car, then sends loan documents. Read the total amount repayable, the comparison rate, and any fees for paying out early. Those three numbers are the contract in miniature.
Settlement
The lender pays the seller directly, whether that is a dealer or a private seller, and you collect the car. On a secured loan the lender registers its interest on the PPSR, the national register of security interests, until the loan is repaid. Then the repayments begin, and the paperwork is done.
Here’s the part of the machine nobody explains.
No car finance broker in Australia is legally required to act in your best interests. That rule exists for mortgage brokers, not car finance. I do it anyway. It’s hard-coded in my DNA.
Who gets paid, and why it changes what you pay
Follow the money and car finance stops being mysterious. The lender earns interest. Fair enough: that is the product. The person arranging the loan is where it gets interesting. Under the traditional model, the broker or dealer is paid a commission by the lender, typically equating to 3 to 6% of your loan amount, built into your rate. You never see it as a line item, but you repay it, with interest, for the life of the loan. And because it scales with the loan, the person helping you can earn more when you pay more. Brokers aren’t the problem. The commission model is the problem. We just removed ourselves from it.
My model is one number: a flat $699, paid by you, disclosed before you commit. I earn 0% commission from lenders, so I have no reason to steer you toward a bigger loan, a longer term or a balloon payment. I read the lending rules of a wide panel of lenders, match your position to the lenders likely to approve you, and a qualified broker reviews every deal before it is submitted. Same lenders. Same loans. The difference is who the arranger works for, and I’m hard-coded to work for you.
The Bottom Line
- Car finance is a lender paying for the car up front and you repaying it over time, usually secured against the car itself.
- There are four main routes to a loan: dealer finance, going direct to a lender, a traditional broker, and an AI broker. Each pays the arranger differently, and that changes what you pay.
- Your repayment is set by four numbers: the amount borrowed, the rate, the term, and any balloon payment. Judge every offer on the comparison rate and the total amount repayable.
- The process runs quote, documents, approval, settlement, and with clean paperwork it can finish in days.
- Start with a soft credit check and apply once, in the right place: every formal application leaves a hard enquiry on your file for five years.
- Traditional broker commission typically equates to 3 to 6% of your loan amount, built into your rate. I charge a flat $699 with 0% commission instead.
