The Number That Shocks Most Car Owners
The average Australian spends between $12,000 and $20,000 per year owning and running a car. For a new mid-size SUV purchased on finance, the number regularly exceeds $22,000 annually once you include depreciation. That's $1,700+ per month — more than many people's rent.
Most car owners focus obsessively on the fuel price at the servo while ignoring the costs that actually make the biggest dent in their budget. This guide breaks it all down.

The 8 Real Costs of Car Ownership
1. Depreciation — The Biggest Cost Nobody Talks About
Depreciation is the single largest cost of car ownership for most Australians, yet it's invisible because it doesn't involve a payment. A new car loses approximately 15–25% of its value in the first year, and another 12–18% per year for the following four years.
A new Toyota RAV4 purchased for $47,000 is worth approximately $35,000 after two years — a $12,000 loss over 24 months, or $500 per month. This is a real cost whether you acknowledge it or not.
Vehicles that hold value best in Australia: Toyota HiLux, Toyota LandCruiser, Mitsubishi Triton, and select hybrid models. Vehicles with worst depreciation: European luxury brands, Korean small cars, discontinued models.
2. Finance / Loan Interest
Most Australians finance their car. The average car loan in Australia sits around $25,000–$35,000 at interest rates of 7–10% for secured loans in 2026.
On a $30,000 loan at 8.5% over 5 years: monthly repayment ~$617, total interest paid ~$7,000. Add this to depreciation and you're already over $15,000 in the first year for finance costs alone.
Use our car loan calculator to see your exact repayment schedule and total interest cost. One extra repayment per year on a typical 5-year loan can save over $1,000 in interest.
3. Fuel
With petrol averaging around $1.85–$2.10/L across Australian capital cities in 2026, and the average Australian driving ~15,000km per year, fuel costs are substantial.
A vehicle with 10L/100km fuel consumption at 15,000km per year uses 1,500 litres of fuel. At $1.95/L that's $2,925 per year or $244/month. A more efficient vehicle at 7L/100km uses 1,050 litres — saving you over $877 per year.

4. Registration and CTP Insurance
Registration fees vary by state and vehicle weight. In 2026, expect:
- QLD: $400–$600/year (registration) + $450–$650 (CTP depending on insurer)
- NSW: $300–$450/year (registration) + green slip $350–$550
- VIC: $900–$1,200/year (combined rego and TAC charge)
- WA: $300–$550/year (registration) + $300–$500 (third party insurance)
Use our car registration calculator to estimate your state-specific registration cost by vehicle type and weight.
5. Comprehensive Insurance
Comprehensive car insurance for the average Australian vehicle runs $1,200–$2,500/year depending on the driver's age, location, vehicle value, and insurer. Young drivers under 25 regularly pay $2,500–$4,000+ per year.
The biggest variable: your excess. A low excess ($500) pushes your premium up significantly. Choosing a higher excess ($1,500–$2,500) can reduce premiums by 25–40% — a good bet if you're a careful driver with emergency savings to cover a claim.
6. Servicing and Maintenance
The rule of thumb: budget 1–1.5% of the vehicle's purchase price per year for servicing and maintenance. For a $45,000 car, that's $450–$675 per year during warranty — rising to $900–$1,500+ as the vehicle ages.
At 60,000–80,000km, expect:
- Timing belt/chain service: $500–$1,200
- Brake pads and rotors: $400–$800
- Tyres (full set): $600–$1,200 (see below)
EVs have significantly lower servicing costs — no oil changes, no timing belts — but battery degradation and replacement ($8,000–$15,000 for a full pack) is a long-term wild card.
7. Tyres
The average set of tyres for a mid-size SUV costs $800–$1,200 fitted. Most tyres last 40,000–60,000km in Australian conditions. At 15,000km per year, that's a new set every 3–4 years — roughly $250–$350 per year amortised.
8. Parking and Tolls
If you commute in a capital city, don't underestimate parking. CBD daily parking in Sydney runs $35–$70/day. Casual parking in inner suburbs: $8–$25/day. Tolls on a typical Sydney commute (e.g., M2 + M7) can add $15–$25/day return — over $3,500 per year for a 5-days-a-week commuter.

How to Reduce Your Car Costs
- Buy 2–3 years old — let the first owner absorb the steep depreciation curve
- Choose vehicles with low insurance ratings — Toyotas and Mazdas consistently outperform European brands on insurance cost
- Pay off your loan early — even one extra payment a year saves thousands in interest
- Service on time, not late — a missed service at 10,000km can turn a $250 oil change into a $4,000 engine repair
- Consider an EV for high-mileage drivers — the fuel and maintenance savings on 25,000+km per year often justify the premium
To model your own car's true annual cost, start with the fuel cost calculator, then add your registration costs via the registration calculator. If you're financing, the car loan calculator will show you the true interest bill over the life of your loan.
For practical cost-saving on the road, a good Bluetooth OBD2 scanner lets you read your own fault codes before heading to a mechanic — potentially saving hundreds in diagnostic fees on a car that just triggered a check engine light.
