The sticker price and the loan repayment are only part of what a vehicle costs you. Total cost of ownership (TCO) adds every expense over the period you own the car — depreciation, running costs, insurance, finance — and converts it to a true monthly or per-kilometre figure. Two vehicles with the same purchase price can have dramatically different TCOs over five years.
1. Depreciation
For most new vehicles, depreciation is the single largest cost of ownership — often 40–50% of the original price over five years. A $50,000 car that's worth $28,000 at the five-year mark has "cost" $22,000 in depreciation alone, before you drive a single kilometre.
- Depreciation is steepest in year one (typically 15–25% of new price) and flattens after year three.
- Popular body styles, low-kilometre examples, and models with strong resale demand (Toyota, Mazda, Subaru) hold value better than less popular models.
- EVs currently depreciate faster than equivalent ICE vehicles in Australia due to rapid model improvement and range anxiety concerns, though this varies by brand.
- For a novated lease, the ATO's minimum residual percentages (28.13%–65.63% of cost, depending on term) put a floor on the vehicle's book value at lease end.
2. Finance interest and fees
If you're borrowing to buy, the interest cost is significant and often underestimated. A $45,000 loan at 8.5% p.a. over 60 months costs roughly $10,500 in interest — that's real money on top of the purchase price. Use Motorate's calculator to get the exact figure for your scenario, then add it to your TCO.
- Establishment fees ($150–$600) and monthly service fees ($5–$15/month) add to the total. A $10/month fee over 60 months is $600.
- Secured loans cost less than unsecured personal loans — typically 2–4% difference in rate.
- Extra repayments reduce interest significantly: an extra $100/month on a 60-month loan at 8% can save roughly $1,500–$2,000 in interest and shorten the term by 6–8 months.
3. Insurance
Comprehensive car insurance in Australia costs $1,200–$3,000+ per year depending on the vehicle, driver profile, postcode, and excess chosen. For a financed vehicle, comprehensive cover is mandatory — you can't choose third-party only when the lender holds security over the car.
- New vehicles attract higher premiums due to higher replacement cost.
- Young drivers (under 25) pay significantly more and often have age-based excesses on top of the standard excess.
- Compare quotes annually — many Australians pay 20–40% more than the market rate by auto-renewing without checking.
- For a novated lease, comprehensive insurance is typically bundled in the running-cost package, which can improve the FBT calculation via ECM.
4. Registration and CTP
Registration costs vary by state and vehicle type. For a mid-size passenger car in NSW, expect $350–$550 for registration plus $600–$700 for CTP insurance (Green Slip) annually. Queensland and South Australia bundle CTP with rego; NSW does not. Use Motorate's on-road cost estimates as a baseline — actual costs depend on your state, vehicle weight, and cylinder/engine class.
5. Fuel or energy
At current Australian fuel prices (~$1.90–$2.10/L for 91 unleaded), a vehicle consuming 9L/100km and travelling 15,000 km per year costs approximately $2,565–$2,835/year in fuel. Diesel is typically cheaper per litre but not always cheaper to run on an efficiency-adjusted basis for non-commercial drivers.
- Electric vehicles cost roughly $3–$5 per 100km to charge at home (at ~30 cents/kWh and ~15–18 kWh/100km), compared to $17–$19 for a 9L/100km petrol vehicle. The gap widens with public DC fast charging rates ($0.40–$0.60/kWh).
- Hybrid vehicles typically consume 4–6L/100km in combined cycles, roughly halving fuel costs vs a comparable ICE vehicle.
6. Servicing, tyres, and repairs
- Most new vehicles have capped-price servicing for the first 3–5 years, typically $200–$400 per service at 10,000–15,000 km intervals.
- Tyres for a mid-size vehicle cost $150–$300 each; a full set every 40,000–60,000 km adds $600–$1,200.
- EVs have lower brake wear (regenerative braking) and no oil changes, but battery replacement (typically not needed within a 5-year ownership period for modern EVs) and tyre wear (heavier vehicles wear tyres faster) are factors to consider.
- Comprehensive insurance covers unexpected mechanical damage caused by an accident, but not general wear and maintenance — factor in a buffer of $500–$1,000/year for unscheduled repairs on older vehicles.
Putting it together
A rough monthly TCO framework for a $50,000 new passenger vehicle in NSW, financed at 8% over 60 months with 15,000 km/year:
- Finance repayment: ~$1,014/month
- Depreciation (implied): ~$367/month ($22,000 over 5 years)
- Insurance: ~$175/month
- Rego + CTP: ~$90/month
- Fuel (9L/100km @ $2.00): ~$225/month
- Servicing and tyres: ~$75/month
- Total: ~$1,946/month — roughly double the loan repayment alone
