Buying a car in Australia is the second-biggest financial decision most people make — right after a home. Yet most Australians spend more time choosing the colour of their car than understanding how their loan actually works.
This guide covers every car finance option available in Australia, what they actually cost you, the traps to avoid, and a newer type of product most people have never heard of — but probably should.
What is car finance?
Car finance is any arrangement where a lender provides money to help you buy a vehicle, which you repay over time — usually with interest. In Australia, there are more ways to finance a car than most people realise, and the differences between them can cost (or save) you tens of thousands of dollars over the life of the loan.
The key variables across all options:
- The loan amount — how much you're borrowing
- The interest rate — what the lender charges you to borrow
- The loan term — how long you have to repay (typically 3–7 years)
- The residual or balloon payment — a lump sum due at the end (in some loan types)
- Who owns the car — you, the lender, or a leasing company
The main car finance options in Australia
1. Standard car loan (secured)
The most common option. You borrow money, the car acts as security, and you repay the full amount plus interest over the loan term. At the end, you own the car outright.
Best for: People who want to own their car and have no plans to upgrade often.
Watch out for: Higher monthly repayments than other options, and you're taking on full depreciation risk — a new car typically loses 15–20% of its value the moment you drive it off the lot.
2. Balloon payment loan
Similar to a standard loan, but a portion of the principal is deferred to the end as a lump sum (the "balloon"). This reduces your monthly repayments during the loan — but you owe a large amount at the end.
Best for: People who want lower monthly repayments and plan to sell or trade in the car at the end of the term.
Watch out for: If the car is worth less than the balloon amount, you could be in negative equity — you owe more than the car is worth.
3. Guaranteed Future Value (GFV) loan
A GFV loan is a specific type of balloon payment loan where the lender guarantees the balloon amount upfront — regardless of what the car is actually worth at the end of the term. This is a significant shift in risk. With a standard balloon loan, you take on the depreciation risk. With a GFV loan, the lender does.
Best for: People who want lower repayments, want to upgrade to a new car every few years, and don't want to take on depreciation risk.
Watch out for: Conditions on the guaranteed value — usually mileage caps and condition requirements.
New to the market: Milam is building a product specifically around the GFV structure, designed to make this type of financing more accessible and rewarding for everyday Australians.
4. Car lease (novated lease)
A novated lease is an arrangement between you, your employer, and a leasing company. Your employer leases the car on your behalf, and repayments come out of your pre-tax salary — reducing your taxable income.
Best for: Salaried employees, especially higher earners where the tax saving is significant.
Watch out for: FBT (Fringe Benefits Tax) implications, and it only works while you're employed.
5. Personal loan for a car
An unsecured personal loan used to buy a car. Because the loan isn't secured against the vehicle, interest rates are typically higher.
Best for: Buying a used car from a private seller, or where a secured loan isn't available.
Watch out for: Significantly higher cost over the loan term compared to a secured loan.
What does car finance actually cost Australians?
The average new car in Australia costs around $40,000–$45,000. Here's what financing looks like across different loan types over 5 years at a 7% interest rate:
| Loan type | Monthly repayment | Total repaid | Car ownership at end |
|---|---|---|---|
| Standard loan | ~$792 | ~$47,520 | Yes |
| Balloon (30%) | ~$621 | ~$43,260 + $12,000 balloon | Your problem |
| GFV loan | ~$621 | ~$43,260 + return car | Lender's problem |
| Novated lease | Varies (pre-tax) | Varies | Leasing co. |
The big trap: you're paying a mortgage on a depreciating asset
Most Australians treat car repayments like rent — something you just pay every month without thinking too much about. But unlike rent, you end up owning something worth significantly less than what you paid.
The smarter question to ask isn't "can I afford the repayments?" but "is this the best way to structure this purchase?"
How to compare car finance options
When you're comparing loans, look beyond the interest rate. Ask:
- What is the comparison rate? This includes fees and gives you a more accurate cost picture.
- Is there a balloon or residual? And if so, who takes on the risk if the car is worth less?
- What are the early repayment penalties? Some loans charge you for paying off early.
- What happens if I want to exit the loan? Life changes — know your options.
- Is the rate fixed or variable? Fixed gives certainty; variable could go up or down.
Car finance and your credit score
Every car loan application triggers a credit enquiry in Australia. Multiple applications in a short window can hurt your credit score. To protect it:
- Use a broker who can do a soft search first
- Space out applications by at least 3–6 months
- Check your own credit report first (free at Equifax, Experian, or Illion)
What's changing in Australian car finance
Fintechs are entering the space. New products like Milam are rethinking how car finance works — offering more transparent structures, cashback mechanisms, and better deals for customers who return their car at the end of the term.
EVs are also disrupting residual values — electric vehicles are still uncertain territory for lenders trying to model depreciation, so GFV loans for EVs are worth scrutinising closely.
