EV Running Costs vs Petrol in Australia: The Real Numbers (2026)

One of the most common questions we hear from buyers considering their first EV is: "But does it actually save money to run?" The honest answer is yes — significantly on fuel, moderately on servicing — but the full picture requires looking at every cost category, including the ones that don't favour EVs.

This guide gives you the real numbers for Australia in 2026, based on current average fuel and energy prices, realistic usage patterns, and honest assessments of both the savings and the additional costs.

Fuel Cost: The Big Saving

This is where EV ownership delivers its most obvious financial benefit. Let's look at the 2026 numbers:

Petrol car: Average Australian petrol prices have been hovering around $1.80 per litre in 2026. A typical petrol passenger car consumes approximately 8 litres per 100km. That's $14.40 per 100km in fuel cost.

Electric vehicle: A typical EV uses approximately 15 kWh per 100km. At an average home electricity rate of around $0.30 per kWh, that's $4.50 per 100km in energy cost.

Saving: approximately $9.90 per 100km — call it ~$10 to keep the maths clean.

Annual fuel savings at 15,000km/year

The average Australian drives approximately 13,000–15,000km per year. At 15,000km:

Solar charging: reducing costs to near zero

If you have solar panels at home, the economics improve further. Charging an EV during daylight hours with excess solar generation can reduce the effective per-kWh cost dramatically — potentially to near zero if your solar system produces surplus energy you'd otherwise export at low feed-in tariff rates.

For a household with a 6.6kW solar system (common in Australia), the excess midday generation is often enough to provide 40–80km of EV range per day at effectively zero ongoing cost. Over a year, this could eliminate the EV's energy bill almost entirely.

Servicing Costs

Electric vehicles have significantly fewer mechanical components that require regular servicing. There's no engine oil, oil filter, spark plugs, timing belt, transmission fluid, exhaust system or fuel filter. This translates directly into lower ongoing servicing costs and longer service intervals.

What EV servicing typically involves:

• Safety inspection and software updates
• Tyre rotation and check
• Brake fluid replacement (every 2 years typically)
• Cabin air filter replacement
• Coolant check (EVs have a battery cooling system)
• Visual inspection of brakes (which wear much slower due to regenerative braking)

Typical EV service costs in Australia range from approximately $100–$400 per service, depending on the brand and what the service includes. Service intervals for many EVs are annual or at 15,000km intervals — similar to petrol cars — but the cost per visit is lower and fewer items need replacement.

Regenerative braking is worth highlighting: EVs slow down by converting kinetic energy back into electricity, which means the physical brake pads are used far less frequently. EV brake pads can last 2–3 times longer than in a petrol car, saving hundreds of dollars over the ownership period.

Registration

Some Australian states offer registration discounts or incentives for EVs, though state-level policies have been shifting in recent years:

• Victoria: Eligible EVs receive a $100 discount on annual registration fees
• Queensland: Provides a registration discount for eligible EVs under $100,000 dutiable value
• Other states: Policies vary — check with your state road authority for current offers, as incentives change over time

Note that some states introduced — and later withdrew — stamp duty exemptions for EVs. The landscape is evolving as governments balance EV promotion against road funding concerns. Be aware that the government is also developing a National Road User Charge for EVs, though timing and rates were still under consultation as of mid-2026.

Insurance

EV insurance costs are broadly comparable to petrol cars of equivalent value, though there are some nuances:

• Some insurers charge slightly higher premiums for EVs, citing higher repair costs (particularly for battery-related damage)
• Battery replacement after an accident can be extremely expensive — this is a legitimate risk factor insurers price in
• As EV adoption grows and repairers gain experience, this gap is narrowing
• Several insurers now offer EV-specific products — it's worth comparing quotes specifically for EV coverage

Overall, insurance is unlikely to be significantly more expensive for most EV buyers, but it's worth factoring a 5–10% premium over a comparable petrol car when budgeting.

Tyres

This is one area where EVs genuinely cost more. There are two reasons:

Weight: EV battery packs add significant mass — often 200–500kg compared to an equivalent petrol car. More weight means more tyre wear.

Torque: Electric motors deliver their full torque instantly, which places greater stress on tyres, especially on acceleration. This accelerates wear on the rear tyres in rear-wheel-drive EVs.

Many EVs require specific tyres rated for their weight and speed requirements. These can be more expensive than standard passenger car tyres. Budget for more frequent tyre replacements or higher tyre costs as part of your EV ownership calculation.

Resale Value

EV resale values have historically been less predictable than petrol equivalents, partly due to uncertainty about battery longevity and partly due to rapid technology improvements making older models feel outdated quickly.

However, the trend is improving. As EV adoption grows and buyers become more comfortable with the technology, used EV demand is strengthening. Models from established or high-volume brands — BYD Dolphin, Tesla Model 3, Hyundai Ioniq 5 — have demonstrated reasonable retained value in recent years.

Battery health is the critical variable for used EV values. Most EVs now offer detailed battery health monitoring and many manufacturers provide battery warranties (8 years or 160,000km is common) that transfer to subsequent owners, which significantly de-risks the used purchase.

The Honest Assessment: Upfront Cost Premium

The most significant financial headwind for EV adoption remains the upfront purchase price. An EV equivalent to a $35,000 petrol hatchback typically costs $5,000–$15,000 more to buy new — though this gap has narrowed considerably with the arrival of sub-$30,000 EVs from BYD and others.

At 15,000km/year and $1,485 in annual fuel savings (plus servicing savings), a buyer with a $5,000 price premium over a comparable petrol car would break even on running costs in approximately 3 years. A $10,000 premium extends that to 5–6 years. A novated lease can accelerate this significantly by reducing the effective purchase price through pre-tax salary packaging.
