A car loan is money you borrow from a bank, credit union, online lender or broker to buy a car, then repay in instalments over a term of usually one to seven years. Most car loans are secured against the car, which usually means a lower interest rate. Noma compares options across a panel of around 25 lenders, so you see the total cost before you sign, not just the weekly repayment. The number to compare is the comparison rate, because it folds most fees in with the interest rate to show the true cost.
A car loan is a fixed-term loan used to buy a vehicle. You borrow an agreed amount, called the principal, and repay it in instalments that include interest, usually weekly, fortnightly or monthly. According to ASIC's Moneysmart, most lenders in Australia offer car loan terms of one to seven years, with three, five and seven-year terms the most common. The loan can be arranged through a bank, a credit union, an online lender, a broker, or the dealership itself at the point of sale.
Once approved, the lender pays out the loan amount, you buy the car, and you make regular repayments until the debt plus interest is cleared. Three things shape what you actually pay: the interest rate, any fees, and the loan term. A shorter term means higher repayments but less interest overall. A longer term lowers your repayment but stretches out the interest, so it costs more in total. This is why comparing the total cost over the full term matters more than comparing the weekly repayment.
The difference is whether the car backs the loan, and it usually decides your rate. A secured car loan uses the car as security for the debt. Moneysmart notes that if you fall behind, the lender can repossess and sell the car to recover its money, and with a secured car loan the lender records its interest on the Personal Property Securities Register until the loan is repaid. Because the lender's risk is lower, secured loans usually carry a lower interest rate. An unsecured car loan is not tied to the vehicle, so the lender assesses you on your income and credit history alone, and the rate is usually higher as a result.
Beyond the interest rate, a car loan can carry several fees, and they affect the real cost. Common ones include an establishment fee to set the loan up, ongoing monthly account fees, a fee if a broker or dealer arranges it, and penalty fees for a missed or late payment. Some loans also charge an early repayment or exit fee if you pay the loan out ahead of schedule. Always ask which of these apply before you sign, because two loans with the same interest rate can cost different amounts once the fees are counted.
The comparison rate is the number that shows the true cost of a loan, so it is the one to compare. Moneysmart defines it as a single figure that combines the interest rate with most of the loan's standard fees, expressed as one annual percentage, and lenders are required to show it alongside the advertised rate. That lets you compare loans on a like-for-like basis rather than the interest rate alone. It will not capture every cost, so still check for stamp duty, on-road costs and any broker fee, which can sit outside the comparison rate. When you compare, line up the comparison rates for the same loan amount and term.
A balloon payment, sometimes called a residual, is a lump sum left owing at the end of the loan term. Structuring a loan with a balloon lowers your regular repayments, because you are not paying off the full value of the car during the term. At the end, you pay out the balloon, refinance it, or trade the car in. Because you carry a higher balance for longer, it generally makes the total cost of the loan higher, so weigh that trade-off before you choose it.
A guaranteed future value, or GFV, is a related but separate product often offered at dealerships. It is sometimes described as a "buyback", which can make it sound like the debt simply disappears. It does not. There is still a lump sum owing at the end, just like a balloon, though a GFV usually gives you the option to hand the car back to cover that amount rather than only paying it out or refinancing. Either way, there is a lump sum to plan for, so it is worth knowing exactly what it is before you sign.
How much you can borrow depends on the lender, the value of the car, and your income and credit history. Lenders assess how much you can responsibly repay before approving a loan amount, in line with their responsible lending obligations. Most want to see that you are an adult with a regular income and a reasonable credit history. Requirements vary between lenders, so comparing a panel rather than applying to just one gives a clearer picture of what you are likely to be approved for, and at what cost.

Car finance is the umbrella term for any way of borrowing to buy a car. A car loan usually refers to a secured or unsecured loan specifically, while options such as novated leases and chattel mortgages are other forms of car finance with different structures. For the full picture, see our guide on the types of car finance in Australia.
Most car loans are secured against the vehicle, since this is usually the cheaper option for the borrower. An unsecured loan is available but tends to carry a higher rate, because the lender is not securing the debt against the car.
A comparison rate combines the interest rate and most standard fees into a single annual percentage figure, so you can compare loans on the same basis rather than relying on the advertised rate alone.
Terms usually run from one to seven years, with three, five and seven years the most common. A shorter term means higher repayments but less total interest, while a longer term lowers the repayment but costs more overall.
Often yes, but check the loan terms first. Some loans charge an early repayment or exit fee, which can offset the interest you would save, so it is worth confirming before you sign or before you pay it out.
Yes. A GFV, sometimes called a buyback, still leaves a lump sum owing at the end of the term, just like a balloon. The difference is that a GFV usually lets you hand the car back to cover that amount. Either way, know the figure before you sign.
The right car loan depends on whether it is secured or unsecured, the term you choose, and the fees attached to it, not just the advertised rate. The clearest way to decide is to compare the total cost across several lenders for the same amount and term.
