Most people budget for a car in two numbers. Rego and fuel. Maybe insurance if they're being thorough.
Then the service bill lands. Then a tyre needs replacing. Then the car's worth thousands less than it was twelve months ago, and nobody actually budgeted for that part at all.
So what does owning a car in Australia actually cost in 2026, once every line item is counted? We pulled together the real annual breakdown, rego costs by state, the servicing and insurance numbers people consistently underestimate, and the cost-per-kilometre figure that sums the whole thing up in one shareable number.
The Real Annual Cost of Owning a Car in Australia
The Australian Automobile Association tracks this every quarter through its Transport Affordability Index, and the numbers are a useful reality check. In the December 2025 quarter, the typical Australian household spent $436.38 a week on transport. That figure models a two-car household, so it's not a single-vehicle number, but the category breakdown below applies just as well if you're working out your own car's costs.
| Category | Weekly cost | Annual cost |
|---|---|---|
| Car loan repayments | $214.38 | $11,148 |
| Fuel | $93.81 | $4,878 |
| Comprehensive insurance | $48.05 | $2,499 |
| Servicing and tyres | $36.30 | $1,888 |
| Rego, CTP, and licensing | $33.82 | $1,759 |
| Roadside assistance | $2.53 | $132 |
| Total | $436.38 | $22,692 |
Strip out the loan repayments, which not everyone has, and the ongoing running cost still sits around $222 a week, or roughly $11,544 a year for a two-car household. For a single mid-size petrol vehicle owned outright, most cost analyses land somewhere between $11,000 and $18,000 a year once every category is included. The purchase price gets all the attention. The annual running cost is what actually determines whether a car fits the budget. Pairing that running cost against everyday saving tips elsewhere in the budget is usually more useful than fixating on the purchase price alone.
One thing worth flagging early: the AAA's own index doesn't include depreciation at all. More on why that matters shortly. And if any single bill in that breakdown lands at a bad time, a small loan is one option worth knowing about rather than letting something like registration lapse.
How Much Does Rego Actually Cost by State?
This is the number most people underestimate, because it varies more than they expect. For a standard four-cylinder passenger car, here's roughly what a year of registration costs across the country.
| State/Territory | Typical annual rego | CTP arrangement |
|---|---|---|
| NSW | $850-$1,100 | Separate (Green Slip, open market) |
| VIC | $750-$1,050 | Bundled (TAC) |
| ACT | $900-$1,200 | Separate (MAI) |
| QLD | $700-$900 | Bundled |
| WA | $700-$900 | Bundled |
| SA | $700-$850 | Bundled |
| TAS | $600-$800 | Bundled |
| NT | $480-$640 | Bundled |
The Northern Territory is consistently the cheapest, while NSW and the ACT tend to run highest, partly because their CTP is priced separately rather than folded into the rego bill. In NSW specifically, CTP is genuinely competitive between insurers, a younger driver in western Sydney might pay $700-900 for a Green Slip alone, while an older driver in a regional postcode could pay under $400 for the identical cover. It's worth comparing before automatically renewing with the same insurer each year.
The underlying formulas vary just as much as the totals. Queensland and Tasmania calculate rego partly on cylinder count, so a four-cylinder hatchback and a six-cylinder SUV pay noticeably different amounts even in the same postcode. Victoria bases its fee on where the car is garaged, with inner-metro postcodes generally paying more than regional Victoria. NSW and Western Australia weight registration toward the vehicle's weight and market value. None of this is obvious until the renewal notice arrives, which is exactly why the bill so often catches people off guard.
Servicing, Insurance, and the Costs People Forget

Servicing and tyres combined average around $1,700-$1,900 a year nationally, but that number hides a wide spread depending on what's actually in the driveway.
- Mainstream Japanese and Korean brands typically service for $250-$450 a visit.
- European brands (BMW, Mercedes, Audi, Volkswagen) run $500-$1,000 per service, sometimes close to double an equivalent mainstream car.
- EVs service for $200-$400, and several manufacturers, Kia and Hyundai among them, throw in complimentary scheduled servicing for the first five years.
Comprehensive insurance is the other big variable. Expect anywhere from $800 to over $2,000 a year depending on age, location, claims history, and the car itself. EV owners currently pay a premium here too, often $400-$800 more annually than an equivalent petrol car, a gap that's expected to narrow as more repairers become EV-accredited.
Then there's the stuff that rarely gets its own line in anyone's budget. A set of mid-range tyres lasts 50,000-70,000km and costs $700-$1,400 fitted, working out to roughly $150-$350 a year once amortised. Brakes, wipers, and general consumables add another $100-$300. Roadside assistance runs $100-$300 depending on the club and cover level. None of these feel significant individually. Together, they're a genuine annual cost most owners never actually tally.
If the car breaks down between paydays and the tow truck or the mechanic wants payment upfront, a fast cash loan exists for exactly that kind of timing gap.
Depreciation: The Cost Nobody Budgets For
Here's the category that dwarfs everything else and almost never makes it into a weekly budget, because it doesn't show up as a bill. It shows up as a smaller number when you eventually sell or trade in.
A new mid-grade SUV around the $48,000 mark can lose $20,000-$25,000 in value over five years. A four-year-old mid-size SUV bought for $32,000 might depreciate a further $3,000-$3,500 a year even as a used purchase. New cars lose value fastest in the first few years; buying two or three years old and letting someone else absorb the steepest part of the curve is one of the more effective ways to reduce total ownership cost without changing anything else about how the car is used.
The AAA deliberately excludes depreciation from its index because it's not a weekly cash outflow, it's a paper loss that only becomes real at sale. That's a reasonable methodology choice for tracking cost-of-living pressure, but it also means the headline "cost of owning a car" figures people see quoted are usually understating the true picture by thousands of dollars a year.
The practical takeaway is less about avoiding depreciation, which is unavoidable, and more about timing it sensibly. A car bought at two or three years old has already absorbed the steepest drop in the curve, meaning the next owner's depreciation from that point is far gentler than the original buyer's. Holding a car longer has the same effect in reverse, the annual depreciation hit shrinks the older the vehicle gets, which is part of why keeping a paid-off car running a few extra years is often the cheapest phase of ownership overall.
The Number Everyone Quotes: Cost Per Kilometre
If there's one figure that sums up the whole picture in a single number, it's this one. The ATO's cents-per-kilometre method uses an official rate that sits at 88 cents per kilometre for the 2025-26 income year, rising to 91 cents per kilometre from 1 July 2026.
That rate isn't arbitrary. It's designed to bundle fuel, registration, insurance, depreciation, and maintenance into a single all-inclusive figure, which makes it a genuinely useful shorthand even outside a tax context. Drive 15,000km a year, a fairly typical figure for a metro commuter, and 91 cents a kilometre works out to roughly $13,650 a year in true running cost. That lines up closely with the independent estimates above, which is reassuring in a "different sources landing on the same number" kind of way.
It's worth remembering the ATO's cents-per-kilometre method caps claims at 5,000 business kilometres a year, so it's not meant as a full running-cost calculator for personal use. But as a mental shortcut for "what does another 10km actually cost me," it's hard to beat.
When a Repair Bill Throws the Budget Out
Servicing is predictable. Repairs, less so. A timing belt, a transmission issue, or a cracked windscreen can land well outside the regular servicing schedule and outside what most people have sitting in savings for exactly that purpose.
A rough rule worth adopting: set aside a small amount each month specifically for car costs beyond fuel and rego, even $30-50 a month adds up to a genuine buffer within a year. It won't cover a major transmission rebuild, but it absorbs the smaller surprises that otherwise turn into a scramble.
For the bigger, badly timed repair bills that a small buffer can't stretch to cover, a repair loan is worth knowing exists as a bridge, ideally sitting behind a proper car cost buffer rather than replacing the need for one.
Key Takeaways
- The true annual cost of owning a car in Australia typically sits between $11,000 and $18,000 for a single mid-size petrol vehicle, once fuel, insurance, servicing, rego, and depreciation are all counted.
- Rego varies significantly by state, from around $480-$640 in the NT to $900-$1,200 in the ACT, largely due to how CTP is priced and bundled.
- Servicing and insurance both vary widely by brand, European cars and older EVs on the insurance side tend to run highest.
- Depreciation is usually the single largest cost of car ownership, and it's the one most budgets completely ignore because it isn't a weekly bill.
- The ATO's 91 cents-per-kilometre rate (from 1 July 2026) is a genuinely useful all-inclusive shorthand for what driving actually costs.
- A small monthly car buffer, on top of everyday saving habits, goes a long way toward absorbing the surprises that a fixed rego-and-fuel budget never accounts for.
Cars cost more than the sticker price suggests, and more than most people budget for even after that. If a genuine gap opens up between the bill and the buffer, MoneyBuddy is there to help bridge it.
