Most people focus on the sticker price and the monthly repayment. But the real cost of car ownership in Australia involves at least eight separate cost categories — and the purchase price is often not even the biggest one over a 5-year period. This guide breaks down every component, with real numbers, so you can make an informed decision before you sign anything.
Before diving into each category, here's a summary of what a typical $50,000 car costs over 5 years for an average Australian driver (15,000 km/year, financed with a personal loan at 8.99%):
The monthly repayment on a $45,000 personal loan at 8.99% over 5 years is approximately $932/month. That's less than half the true monthly cost of ownership. The repayment figure alone is a deeply misleading basis for a financial decision.
Depreciation is the loss in market value of your vehicle over time. It's invisible — you don't write a cheque for it — but it's typically the largest single cost of car ownership, often exceeding fuel costs, finance costs, and running costs combined.
For a new car, depreciation is steepest in the first year — typically 15–25% of the purchase price. A $50,000 car can be worth $38,000–$42,500 after just 12 months, purely from transitioning from "new" to "used." This is sometimes called the "drive-away depreciation hit."
| Year | Typical Rate | Value of $50k car | Value lost that year |
|---|---|---|---|
| New (purchase) | — | $50,000 | — |
| Year 1 | 18% | $41,000 | $9,000 |
| Year 2 | 14% | $35,260 | $5,740 |
| Year 3 | 12% | $31,029 | $4,231 |
| Year 4 | 10% | $27,926 | $3,103 |
| Year 5 | 10% | $25,133 | $2,793 |
Total depreciation over 5 years on this example: approximately $24,867 — almost half the original purchase price. This is why the "true cost" of ownership is so much higher than people expect.
Buy a 2–3 year old car instead of new. The steepest depreciation curve has already run — you buy at the bottom of the first big drop. Popular models with strong resale (Toyota HiLux, Mazda CX-5, Toyota RAV4) depreciate slower than average. Avoid unusual colours and configurations that limit your resale market.
Before you even drive away, there are mandatory government charges that add to your effective purchase price.
A state government tax on the vehicle purchase, calculated on the market value. It varies significantly by state — for a $50,000 vehicle, here's what you'd pay:
| State | Stamp Duty on $50k vehicle | Notes |
|---|---|---|
| VIC | $3,000 | 6% above $57k; 3.5% below |
| NSW | $2,500 | 5% above $45k |
| QLD | $1,550 | 3.1% up to $100k |
| WA | $1,637 | Tiered rate structure |
| SA | $2,000 | 4% flat |
| TAS | $1,500 | 3% flat |
| ACT | $1,500 | 3% flat |
| NT | $1,500 | 3% flat |
A federal tax at 33% on vehicles above $80,567 (standard) or $89,332 (fuel-efficient vehicles including EVs), applied to the portion above the threshold divided by 1.1 for GST. On a $100,000 vehicle, LCT adds approximately $5,880. On vehicles under the threshold, LCT doesn't apply.
Required in all states to register a vehicle. The cost varies by state, vehicle type, and insurer. It's typically included in registration in some states (e.g. VIC) or purchased separately (e.g. NSW). Expect $400–$700/year for a standard passenger vehicle.
The On-Costs tab in the Veercal calculator calculates your exact stamp duty by state, LCT if applicable, and adds these to your effective purchase price across all five finance structures.
If you're borrowing to buy, the interest you pay is a real cost of ownership that doesn't get enough attention. On a $45,000 loan at 8.99% over 5 years, you'll pay approximately $11,800 in interest — on top of the purchase price.
The interest rate matters enormously. The difference between an 8% rate and a 12% rate on the same loan is about $5,800 over 5 years — nearly the same as a year of fuel costs. Always compare comparison rates across at least three lenders before accepting the first offer.
The advertised rate doesn't include fees. A loan advertised at 6.99% with a $500 establishment fee and $15/month account fee may have a comparison rate of 8.2%. The comparison rate is the one that matters for comparing products.
At 15,000 km/year with a 9L/100km car and fuel at $2.10/L, you'll spend approximately $2,835/year on fuel. Over 5 years that's $14,175. For an efficient vehicle at 6L/100km, the same distance costs $1,890/year — a $4,425 difference over 5 years.
For EVs, home charging at 18kWh/100km and a $0.28/kWh rate costs approximately $756/year for the same 15,000 km — a saving of over $2,000/year versus the average petrol car.
Fuel efficiency matters most for high-km drivers. If you drive 30,000+ km/year, a hybrid or EV can save $3,000–$5,000/year in fuel costs alone — often enough to justify a higher purchase price over the ownership period.
Comprehensive car insurance for a $50,000 vehicle typically runs $1,400–$2,200/year depending on your age, location, driving history, and the vehicle. Premiums are highest for drivers under 25 and in major urban areas. Shopping around annually — not auto-renewing — typically saves $200–$600.
For financed vehicles, comprehensive insurance is usually compulsory under your loan or lease agreement. Gaps in cover can trigger a loan default.
Annual registration costs include the government registration fee, a road trauma levy (in some states), and CTP insurance. Combined, this typically runs $700–$1,200/year for a standard passenger vehicle, with significant variation by state and vehicle type.
Manufacturer-scheduled servicing costs vary widely. A small Japanese SUV might cost $250–$350 per service; a European luxury vehicle can cost $600–$1,200. Budget $600–$1,000/year for an average new car. This increases as the vehicle ages and moves out of warranty.
EVs have meaningfully lower servicing costs — no oil changes, fewer brake replacements (regenerative braking reduces wear), and fewer mechanical failure points. Typical EV servicing runs 40–60% less than an equivalent ICE vehicle.
A set of quality tyres for a standard vehicle costs $600–$1,400 fitted, depending on size and brand. At 15,000 km/year most tyres last 3–4 years on a balanced rotation. Budget $400–$700/year amortised. SUVs and high-performance vehicles with larger diameter wheels cost more.
Knowing where the costs sit tells you where to focus. In order of impact:
