Electric vs Petrol Running Costs Australia: Which Is Cheaper in 2026?

Australia has two factors that change EV economics significantly: the highest residential rooftop solar penetration in the world, and the FBT exemption for EVs under the LCT fuel-efficient threshold (a major perk for novated leasing). Without solar, EV running costs in Australia look more like the UK — with solar, they can be effectively zero. This guide runs the numbers across petrol, grid charging, solar charging and the novated lease angle so you can decide if an EV stacks up for your driving.

Cost Per Kilometre: EV vs Petrol

Cost per km depends on energy price and vehicle efficiency.

EV cost per kilometre
Typical efficiency: 6 km per kWh (real-world, mixed driving).
- Excess rooftop solar (effective cost ~$0.05/kWh): $0.008 per km
- Off-peak overnight tariff at $0.18/kWh: $0.030 per km
- Flat residential rate at $0.32/kWh: $0.053 per km
- Tesla Supercharger at $0.65/kWh: $0.108 per km
- Chargefox / Evie DC fast charging at $0.55–0.70/kWh: $0.092–0.117 per km

Petrol vehicle cost per kilometre
Typical efficiency: 8 L/100 km (real-world, mixed driving — typical for a sedan or compact SUV).
- Petrol at $1.80/L: $0.144 per km
- Petrol at $2.00/L: $0.160 per km
- Petrol at $2.20/L (regional / outback): $0.176 per km

Headline takeaway: with rooftop solar and overnight charging, an EV in Australia can cost 1–3 cents per kilometre — roughly 5–20x cheaper than a petrol car. On flat grid rates the gap narrows but the EV is still 3x cheaper. The economics flip only on Tesla Superchargers and DC fast charging, where cost per km is comparable to petrol.

Solar, Home and Public Charging

Australia has the world’s highest residential rooftop solar penetration — over a third of homes — and that fundamentally reshapes EV economics for owner-occupiers.

• Rooftop solar charging: Most Australian solar households export power to the grid for $0.04–0.08/kWh feed-in tariff but pay $0.32/kWh to import. Charging an EV from excess solar instead of exporting saves the difference — effectively $0.05/kWh of "free" charging. For a household doing 15,000 km/year, this can save $1,000+ per year vs grid charging.
• EV-specific overnight tariffs: AGL, Origin, Energy Australia and several others offer EV-specific or super-off-peak tariffs at $0.10–0.20/kWh between 11 pm and 6 am. A 75 kWh battery 20–80% charge costs $4.50–$9 on these rates.
• Flat residential rates: $0.28–0.40/kWh across most of Australia. Same charge costs $13–$18. Still cheaper than petrol but not as compelling.
• Tesla Supercharger: $0.55–0.75/kWh in Australia. A 20–80% charge costs $25–$34. More expensive per kWh than most other markets due to limited grid scale.
• Chargefox / Evie / NRMA / AmpCharge: $0.55–0.75/kWh DC fast. Free or subsidised at some NRMA stations in NSW for members.
• Petrol prices: Vary $0.30–0.50/L between metropolitan cycle lows and regional/outback highs. The "petrol cycle" in capital cities means timing fills well can save $200–$400 per year.

Servicing and Maintenance

Fewer moving parts is the structural advantage of an EV. No engine oil, spark plugs, timing belt, transmission fluid or exhaust system. Combined with Australia’s tendency toward longer ownership horizons, this compounds over time.

• Annual service costs: Independent data and manufacturer comparisons place EV servicing at roughly 30–50% lower than a petrol equivalent. A typical EV service in Australia is $200–$350; a petrol equivalent is $400–$700 depending on brand.
• Logbook servicing: Many EV manufacturers (Tesla, Polestar, BYD) have effectively eliminated scheduled logbook servicing — annual or biennial inspections only. Petrol car owners still face mandatory dealer logbook servicing to preserve warranty.
• No oil changes: Petrol service every 10,000–15,000 km costs $250–$500 at a dealer. EVs eliminate this entirely.
• Regenerative braking extends pad life: Most EV owners report 80,000–150,000 km between brake pad replacements vs 40,000–70,000 km on a petrol car.
• What EVs still need: Tyres (sometimes more frequent on heavy EVs — Model Y, EV6, ID.4 owners report higher tyre wear), cabin filters, brake fluid every 2 years, 12V battery every 4–6 years, and tyre rotations.

FBT Exemption, LCT and State Incentives

Australia’s biggest EV incentive isn’t a rebate — it’s the FBT exemption for EVs under the LCT fuel-efficient threshold. For salary-packaging employees, this is enormous.

• FBT exemption (federal): Eligible EVs and PHEVs are exempt from Fringe Benefits Tax when packaged through a novated lease. For most middle-to-high earners, this turns a $70,000 EV into the equivalent of leasing a $50,000 petrol car after-tax. PHEVs lose this exemption from 1 April 2025 — BEVs only after that date.
• LCT fuel-efficient threshold: $91,387 (2024–25) vs $80,567 for non-fuel-efficient cars. EVs and PHEVs qualify for the higher threshold, meaning luxury EVs like Polestar 2 and Model Y Performance avoid LCT altogether.
• NSW: Stamp duty exemption on EVs under $78,000 (saved roughly $1,500–$2,500); EV registration concession; rebates ended in 2024 but exemptions remain.
• Victoria: $100 annual reduction on EV registration; ZLEV road-user charge ($0.026/km) was struck down by the High Court in 2023 — currently no per-km charge.
• QLD: $3,000 ZEV rebate ended for new orders, but stamp duty discount continues.
• ACT: Two years free registration for EVs; up to $2,000 grant; stamp duty exemption.
• WA: $3,500 ZEV rebate (until 50,000 cars or 10 May 2025, whichever comes first).
• SA: $3,000 rebate ended; EV registration discount continues.
• TAS: Stamp duty exemption for EVs.
• NT: Stamp duty discount and free registration for EVs.

Insurance Costs

EV insurance in Australia is typically 10–25% higher than an equivalent petrol car. The gap has narrowed somewhat since 2023 as more insurers added EV-specific policies.

• EV insurance premiums: Typically 10–25% higher than equivalent petrol vehicle. Comprehensive premiums on a Model Y in Sydney average $2,200–$2,800/year vs $1,800–$2,200 for a comparable petrol SUV.
• Why higher: Higher repair costs, specialist EV-trained technicians, and limited body shop networks. Tesla’s aluminium panels and battery repairs are especially expensive.
• How to reduce premiums: Compare specialist EV insurers (RACV, Allianz, NRMA all offer EV products), increase your excess, pay annually rather than monthly, and bundle home/contents.

Depreciation

EV depreciation in Australia has tracked global trends — fast for new EVs (Tesla price cuts and BYD entry), excellent value on used EVs.

• New EVs depreciate faster: Some Tesla and BYD models lost 35–50% of their value in three years due to price cuts and new model entries.
• Used EVs offer outstanding value: A 2–3 year old Model 3, Polestar 2 or Atto 3 can be 30–45% off original price on Carsales, AutoTrader and CarsGuide. Combined with cheap rooftop solar charging, the math is excellent.
• Established petrol models depreciate predictably: Toyota Corolla, RAV4 Hybrid, HiLux, and the LandCruiser hold residual exceptionally well in Australia — they’re among the slowest-depreciating cars in the world.
• Long-term holding: EVs held 8+ years in Australia, especially for rooftop-solar households, deliver substantial fuel savings that outweigh depreciation drag.

Long-Term Ownership: 5-Year Cost Comparison

A realistic 5-year comparison for an Australian driver covering 15,000 km/year, with rooftop solar.

EV (50% solar charging at $0.05 effective, 50% off-peak at $0.18/kWh, 15,000 km/year):
Fuel: $1,440 (75,000 km ÷ 6 km/kWh × $0.115 blended)
Servicing (5 years): $1,250
Registration: $4,000 (5 years averaged)
Insurance: $12,500 (5 years at $2,500/yr)
Depreciation (new $60k EV, 50% over 5 years): $30,000
Total 5-year cost: ~$49,190

Petrol vehicle (8 L/100 km, $2.00/L, 15,000 km/year):
Fuel: $12,000 (75,000 km × 8/100 × $2.00)
Servicing (5 years): $3,000
Registration: $4,000
Insurance: $10,000 (5 years at $2,000/yr)
Depreciation (new $50k petrol car, 40% over 5 years): $20,000
Total 5-year cost: ~$49,000

Roughly even on total cost over 5 years — but the EV saves $11,000+ in operating costs (fuel + servicing) before depreciation. The math gets dramatically better with FBT-exempt novated leasing (effective price drops $15,000+) or with a higher solar share. It gets worse with grid-only charging and no novated lease structure.

Which Should You Choose?

The financial answer depends heavily on solar access, novated leasing eligibility and annual kilometres.

• Choose an EV if: You have rooftop solar (the operating-cost gap becomes huge); you can salary-package via novated lease (FBT exemption is enormous); you do 12,000+ km per year; you’re a long-term owner (8+ years); or you want metropolitan HOV/T2/T3 lane access where applicable.
• Choose a petrol car if: You don’t have home charging or solar (public-only EV ownership erases most of the cost advantage); you do less than 8,000 km per year; you regularly need long-distance highway capability without DC charging stops (outback travel); or you want lowest absolute cost — a used Camry or RAV4 Hybrid can’t be beaten on upfront price.
• Consider a hybrid if: You want reduced fuel costs without solar/home charging. Toyota RAV4 Hybrid (5.0 L/100 km) and Camry Hybrid (4.7 L/100 km) deliver near-EV economy without charging anxiety, and Toyota residual values protect resale.

Honest answer for most Australian drivers in 2026: with rooftop solar and a novated lease, an EV is the clear financial winner. Without either, the case is closer — a hybrid often makes more sense than either a pure EV or a conventional petrol car.
