Secured car loan: how it works and what it costs

A secured car loan is a loan where the car you buy becomes the lender's security. The lender registers an interest in the vehicle, and can repossess and sell it if you stop paying. Because that security lowers the lender's risk, secured car loans are usually priced below unsecured personal loans.

That one difference sits behind most of what follows: why the pricing tends to be lower, why the lender cares about the car's age and condition as much as your income, and why you cannot sell the car cleanly until the loan is finished.

What is a secured car loan?

A secured car loan is consumer credit with a security interest attached to one specific asset — the vehicle being financed. You buy the car, you are on the registration, and you drive it like any other owner. What sits behind that is the lender's right to take and sell the car to recover what it is owed if the loan goes unpaid. The lender records that right on the Personal Property Securities Register, the national register of security interests over goods, so anyone who later checks the vehicle can see that money is owed on it. Most car loans written in Australia are secured this way, because a car is easy to identify, easy to value and easy to sell. The practical consequence for you is that the loan is tied to one particular car, and the lender has a say in which car qualifies.

The security is what makes a secured car loan cheaper, and it is also what makes it harder to walk away from: one loan, one car, and a registered interest that has to be cleared before the car can change hands.

Is a secured car loan cheaper than an unsecured personal loan?

Usually, though not always, and the reason is risk rather than generosity. A lender holding security can recover part of its loss if the loan fails, so it prices that loan below an equivalent unsecured one. That is the general pattern; the rate any one lender offers still comes out of its own assessment of your income, expenses, credit history and the vehicle, so two people can be quoted differently on the same amount. The trade-off is flexibility. An unsecured personal loan is not tied to an asset, so it can pay for a private-sale car of any age, a heavily modified vehicle, or something no lender would take as security — and you can sell that car whenever you like. Where a secured loan is available for the car you actually want, it is normally the lower-cost structure. Where it is not, the unsecured route exists for a reason.

What can be used as security for a car loan?

The car itself, and lenders are selective about which cars they will take. Because the security has to be worth something at the end of the term, age at the end of the loan matters more than age at the start: an older car on a long term leaves security worth very little by the final repayment. Condition, how readily the model resells, and whether it has ever been written off or substantially modified all feed into the decision. The purchase channel matters too: a licensed dealer sale with clear title and a proper invoice is more straightforward than a private sale or an auction purchase, which some lenders treat differently or will not fund. Imports, kit cars and commercial conversions are usually assessed case by case. Our guide to second-hand car finance covers what lenders check on a used vehicle.

What happens if you fall behind on a secured car loan?

The car is at risk, and that is the central difference from unsecured credit. The lender's security gives it the right to repossess the vehicle and sell it to recover the outstanding balance, and if the sale does not cover what is owed, the shortfall generally remains your debt. It is not an immediate step. Australian consumer credit law sets out notice requirements and a process a credit provider has to follow before it enforces security, and a borrower in difficulty can ask the lender to vary the arrangement rather than wait for enforcement. Timing matters: the options are widest while the loan is current and narrowest once enforcement has begun. If repayments are becoming difficult, contact the lender early. Licensed credit providers also belong to an external dispute resolution scheme, which can consider a complaint at no cost to the borrower.

Can you sell or trade in a car that still has finance on it?

Not cleanly, and not without dealing with the loan first. While the security interest is registered, the lender's claim over the vehicle survives a sale, so a buyer who pays you and drives away can find the car is still encumbered. The ordinary way through is a payout figure: you ask the lender what the loan would cost to finish on a given date, and that amount is paid from the sale proceeds so the security can be released. If the car is worth less than the payout, you fund the difference, which is why negative equity turns up so often on long terms. A dealership handling a trade-in will usually arrange the payout as part of the transaction. Any buyer can check whether money is owed on a vehicle first, and our guide to checking finance owing on a car explains how. Finishing early can also carry fees — see our car loan early payout guide.

What do lenders look at when they assess a secured car loan?

Two things at once: you, and the car. On your side, a lender will generally want identification, evidence of income, a picture of your regular expenses and existing commitments, and consent to check your credit file. It is working out whether the repayments fit your circumstances without substantial hardship, which is a responsible-lending obligation rather than a courtesy. On the car's side it will want the vehicle's details — make, model, year, odometer, and who you are buying from — because the security's likely value shapes how much it will lend and over what term. A deposit is not always required on a secured loan, but it changes the picture: borrowing less against the same asset lowers the lender's exposure and can widen the options open to you. Approval depends on the lender's assessment, and decisions vary by lender and by the documents you can produce. Our guide to car loan deposits goes through how much is worth putting in.

How do you compare two secured car loan offers?

Put them in the same units before you judge either one. Get each offer in writing as an amount financed, a term in months, an interest rate per annum, a comparison rate, every fee by its name, and any balloon or residual amount due at the end. The comparison rate matters because it folds set-up and ongoing fees into a single figure, so two loans advertising the same rate are not necessarily the same price. Then look at the conditions attached to the security: whether extra repayments are allowed, what finishing early costs, whether the rate is fixed for the term, and whether comprehensive insurance is required — on a secured car loan it often is. Work out the repayments yourself from the amount, rate and term rather than taking a weekly figure on trust — our car loan calculator will do it, and our comparison rate calculator shows how fees change the real cost. Compare the total of all repayments plus any balloon, not the weekly number.

If you are not certain the car you want can be financed as a secured loan, settle that before you buy it rather than after. Message us on WhatsApp with the vehicle, roughly what you want to borrow and your timeframe, and we will tell you what the options look like across our panel, so you can see whether a secured structure fits or whether an unsecured loan would suit you better. Our car loan broker service explains how that works, and our guide to car loans covers the other structures. This information is general only and does not take your personal circumstances into account. All lending is subject to the lender's credit assessment and approval.
