A car can be a practical tool: it gets you to work, carries kids, and may be essential outside well-serviced public transport areas. But a car loan deserves more scrutiny than it often gets.
Unlike a home, a car usually depreciates while you are paying interest on it. In a year when budgets remain tight — ABS reported annual CPI of 3.5% to July 2026, with housing up 5.0% — a payment that seems affordable at the dealership can quietly limit your options for years.
The double hit: depreciation and interest
Depreciation means a vehicle loses resale value over time. The steepest drop is commonly in the early years, especially for a new car. Interest is what you pay the lender for borrowing the money. Put them together and you can be paying down a debt while the asset underneath it is shrinking.
Consider a simplified example. You buy a $45,000 new SUV, put down $5,000, and borrow $40,000 over five years at 9% p.a. The repayment is roughly $830 a month. Over 60 months, you pay about $49,800 — around $9,800 in interest before possible establishment fees, dealer add-ons and insurance.
Now imagine the car is worth $30,000 after two years. Depending on how the loan amortises, you might still owe roughly $25,000 to $27,000. You have some equity, but much less than your payments may have led you to expect. A bigger loan, a smaller deposit, a higher rate or a seven-year term can make the gap worse.
Longer terms reduce the monthly figure, not the price of borrowing. They often keep you paying while the vehicle is well into its lower-value years. That is why a repayment alone is a poor measure of affordability.
Negative equity is the trap to avoid
Negative equity means you owe more on the loan than the car could reasonably sell for. If you need to sell after an accident, job change, new baby, separation or move, you must find extra cash to clear the lender.
It can also lead to a costly cycle: rolling the old shortfall into the finance for the next car. The new loan then starts larger than the new vehicle’s price, making the next trade-in harder again.
Be especially cautious if a deal includes:
- no deposit or a very small deposit;
- a loan term longer than five years;
- add-ons folded into finance, such as warranties, paint protection or accessories;
- an inflated trade-in value paired with a higher purchase price;
- a balloon payment due at the end; or
- a salesperson focusing only on “$X per week”.
Ask for the cash price, comparison rate, total amount repayable, every fee, and the balance owing after 12, 24 and 36 months. Take the quote home. A good deal will still be available after you have read it without pressure.
The used-car cash alternative
A reliable used car bought with cash is not glamorous, but it can protect your future cash flow. Say you have $15,000 saved and buy a well-inspected, economical used car for $13,000, leaving $2,000 for registration, insurance, immediate maintenance and surprises.
Compared with the $830 monthly loan above, you free up almost $10,000 a year in repayments. Even if you redirect only $500 a month into an emergency fund, high-interest debt or long-term investing, that is $6,000 a year working for you rather than for a depreciating car.
Cash is not a licence to buy blindly. A cheap car that needs a $4,000 transmission repair is not cheap. Before handing over money, pay for an independent pre-purchase inspection, check the service history and vehicle identification details, confirm it is not encumbered by finance, and price insurance before committing. Set aside a repair buffer rather than spending every dollar on the purchase.
If $13,000 is not realistic, a smaller loan for a modest, dependable used car can still be a better compromise than financing a $45,000 vehicle. The aim is to borrow less and repay it faster, without draining your emergency savings to zero.
Put the car in the context of your whole budget
Car ownership is more than the loan: fuel or charging, insurance, servicing, tyres, registration, parking and tolls all count. Add those costs to the repayment and divide by your monthly take-home pay.
For example, a $830 loan repayment plus $180 insurance, $220 fuel, $100 registration and servicing provision, and $70 parking or tolls totals $1,400 a month. On take-home pay of $5,000, that is 28% of net income before rent, food or bills.
That pressure is real when so many households are already stretched. Finder’s 2026 research says about 52% of Australians spend their pay before the next payday. If your car costs are forcing regular credit-card use, the problem can escalate quickly: RBA data puts average card rates near 20.99% p.a., and Canstar reported about $19.4 billion of Australian card debt accruing interest in July.
If you already have the loan
Do not panic or shame yourself. Start with facts. Get your payout figure from the lender, estimate a realistic private-sale value, and compare the two. Then list the interest rate, remaining term, fees and whether extra repayments are allowed.
You may be able to refinance to a lower rate, make modest extra repayments, sell the car if the gap is manageable, or keep it longer after the loan ends. Avoid replacing it simply because you are tired of it. If repayments are becoming unmanageable, contact the lender early and ask about hardship options; ignoring notices narrows your choices.
A car should support your life, not consume the money you need to build one. Choose the safest reliable option you can afford, keep the loan short if you must borrow, and give your future self room to breathe.
