Ask most Australians what a car costs and they will quote the price on the windscreen. Ask what it actually costs to own for a year and most go quiet – because the honest answer is usually two or three times higher than anyone budgets for, and it is the gap between those two numbers that catches drivers out.
The national picture, drawn from the AAA’s Transport Affordability Index, puts the average Australian household’s total annual transport bill at around $24,484. That figure folds in fuel (roughly $4,775 a year), registration, licensing and compulsory third party (CTP) insurance (about $1,838), comprehensive insurance (around $2,632), maintenance and tyres (close to $1,915), and loan repayments (about $11,252). Strip out the loan and the AAA’s all-in national average still lands closer to $17,800 a year once tolls are folded back in.
What a typical car really burns through each year
A separate 2026 cost analysis from ShopBack puts real annual running costs at $11,000 to $18,000 for a typical mid-size petrol car, once depreciation, fuel, servicing, insurance and registration are added together. On that reckoning, a $25,000 hatchback runs to roughly $11,000 a year, while a $50,000 SUV climbs to around $15,500. As ShopBack’s analysis frames it, cheap-to-buy is not the same as cheap-to-own.
RACQ’s 2025 running-cost study of 55 Australian models backs that up in granular detail. Average monthly costs on conventional finance range from $979 for light passenger cars ($11,749 a year) up to $1,955 for large SUVs ($23,460 a year). Two similarly-priced cars can land in quite different places: RACQ’s figures show a 2025 Suzuki Swift Hybrid priced at $28,350 drive-away in Queensland running to $10,494 a year on average, while a 2025 Hyundai Venue priced almost identically at $28,865 runs to $11,154 a year – the difference coming mostly from fuel and insurance rather than the sticker price.
The cost you don’t notice losing
Of every dollar spent on ownership, depreciation usually does the most damage and gets noticed the least. Australian vehicles typically lose 50 to 60% of their value over five years, with 20 to 25% of that gone in the first year alone – whether the car is driven daily or left in the driveway. Toyota, Mazda and Subaru models tend to hold their value best, retaining around 50 to 60% after five years, while European luxury brands often keep only 35 to 45%.
Fuel and depreciation together typically account for 45 to 65% of total five-year ownership cost, comfortably outweighing servicing, insurance and registration combined. A calculation from Calk-AU’s total ownership calculator shows a mid-size petrol car with a $45,000 purchase price running to $51,150 in total cost over five years – more than the purchase price again, swallowed by depreciation, fuel, insurance, registration, servicing and tyres.
Why your postcode changes the sum
Registration costs alone vary enough by state to throw off any running-cost figure borrowed from somewhere else. Queensland’s rego and licensing for a standard four-cylinder car starts from $932 a year – a figure Budget Direct notes many buyers never check before settling on a model. Other states price registration differently again depending on engine size and vehicle type, so a running-cost estimate calculated for a Sydney driver will not hold for someone in regional Western Australia.
How you pay for the car changes the total too. Buying outright carries the lowest total cost of ownership because it avoids interest and finance fees entirely, though it ties up capital upfront. Conventional finance builds equity in the car but can add $5,000 to $15,000 in interest over a five-year term – a cost that is invisible on the monthly repayment figure and easy to underestimate. Novated leasing can lower the post-tax cost through pre-tax salary deductions, particularly for electric vehicles (EVs) exempt from fringe benefits tax, but it locks the arrangement to current employment, which matters if a job change is on the cards.
Where electric cars fit the sum
EVs run 60 to 70% lower on energy and servicing costs than petrol equivalents, with typical annual running costs of $9,500 to $13,500. The catch is a higher purchase price and faster early depreciation, so the break-even point against a comparable petrol car usually sits four to seven years out, depending on annual kilometres and access to home charging.
Spring brings a practical window for buyers focused on the purchase price rather than the newest features. Manufacturers typically release model-year updates around now, pushing outgoing-model stock into clearance pricing – useful if a lower price matters more than the latest safety or efficiency figures. It is also worth checking for outstanding recalls before any long-weekend trip, since notices tend to increase at this time of year.
Before signing anything, check the manufacturer’s capped-price servicing schedule, confirm your own state’s registration and CTP figures rather than a national average, and have the dealer walk you through the full drive-away price. Comparing cars on cost-per-kilometre or cost-per-month over a five-year horizon – rather than sticker price alone – is the only way to see the real gap between two similarly priced options.
The number that matters is never the one on the windscreen. It is the one that arrives quietly every month for the next five years, in fuel receipts, service invoices, registration renewals and a resale value that has already slipped away before you notice it going. Work that figure out before you buy, and the car you choose starts making financial sense rather than just visual sense on the driveway.
