EV vs Petrol Car: True Running Costs in Australia (2026)
Compare running costs of electric vehicles versus petrol cars in Australia: fuel, charging and maintenance.
Why Australians Are Reconsidering Electric in 2026
With petrol prices sitting above $2.30 per litre nationally — and threatening $3 or even $4 in worst-case scenarios linked to the Strait of Hormuz crisis — the question of switching to an electric vehicle has never been more urgent for Australian drivers.
EV sales in Australia hit record numbers in 2025, accounting for roughly 11% of new car sales. The arrival of affordable models like the BYD Dolphin ($34,890), MG4 ($33,990), and Tesla Model 3 Standard Range ($52,490) means electric cars are no longer just for early adopters. But is an EV actually cheaper to run day-to-day? And does the maths still work once you factor in charging infrastructure, the incoming EV road user charge, and Australia's higher electricity prices?
We've run the numbers across every major cost category to give you a complete picture.
Fuel vs Electricity: The Core Cost Comparison
This is where EVs win decisively. The average Australian drives about 15,000 km per year. Here's what that costs in fuel versus electricity:
| Vehicle Type | Annual Consumption | Charging Cost | Annual Cost | |---|---|---|---| | Petrol (Toyota Corolla, 6.8 L/100km) | 1,020 litres | — | **$2,377/year** | | Electric (Tesla Model 3 SR, 14.4 kWh/100km) – Home | 2,160 kWh | 32c/kWh | **$691/year** | | Electric (Tesla Model 3 SR) – Public charging | 2,160 kWh | 60c/kWh | **$1,296/year** |
**Annual fuel saving with home charging: $1,686**
:::success EV Fuel Economics About **80% of EV charging happens at home or work**, so home charging costs apply to most drivers. Even if you rely entirely on public fast chargers, you'd still save over **$1,000 per year**. At higher petrol prices ($3.00/L), EV savings jump to nearly **$2,370/year**. :::
The EV Road User Charge: How Much Will It Really Cost?
One cost that petrol drivers don't pay directly is the EV road user charge — a per-kilometre tax designed to replace the fuel excise that EV owners don't contribute to.
**Current status (March 2026):** - NSW already charges **2.974c/km** for battery EVs - A national charge of **~2.5c/km** is being negotiated, scaling to **5.3c/km** by 2027–28 - National scheme expected: **1 July 2027** (or earlier if EVs reach 30% of new car sales)
**Annual cost by rate (15,000 km/year):** - At 2.5c/km: **$375/year** - At 5.3c/km (full rate): **$795/year**
:::note Road User Charge vs Fuel Excise For comparison: fuel excise on petrol is 50.6c/litre. A Corolla using 1,020 litres pays **$516/year** in fuel excise. Even at the full 5.3c/km EV rate ($795/year), it's slightly higher — but the overall fuel cost saving ($1,686) far outweighs it. **Net EV saving after road user charge: $891/year** :::
Maintenance: The Hidden EV Advantage
This is often underestimated. Electric vehicles have dramatically fewer moving parts than internal combustion engines — no oil to change, no spark plugs, no timing belts, no exhaust system, no transmission fluid.
**Typical annual maintenance costs:** - Petrol car (mid-size sedan): $800–$1,200/year - Electric car (equivalent): $300–$500/year
**Key maintenance differences:** - **Oil changes:** Petrol cars need them every 10,000–15,000 km ($120–$200 each). EVs need zero. - **Brake pads:** EVs use regenerative braking, which dramatically reduces brake pad wear. Many EV owners go 100,000+ km before needing new pads. - **Transmission:** EVs have a single-speed reduction gear. No gearbox servicing, no clutch replacement. - **Coolant:** EVs still have thermal management systems, but maintenance intervals are much longer (typically every 4–6 years). - **Tyres:** EVs do wear tyres slightly faster due to instant torque and heavier weight. Budget an extra $100–$200 per year for tyre wear.
:::tip EV Maintenance Savings **Annual maintenance saving: $400–$700** Over a 10-year ownership period, this adds up to **$4,000–$7,000** — enough to offset a meaningful chunk of the EV's higher purchase price. :::
Home Charging Setup: The Upfront Cost
Most EV owners install a dedicated Level 2 home charger (7kW wall box) for faster, safer overnight charging. You can charge from a standard power point, but it's slow — about 10–15 km of range per hour.
**Home charger installation costs:** - Wall box unit: $800–$1,500 - Electrician installation: $500–$800 - Switchboard upgrade (if needed): $300–$600 - **Total: $1,500–$2,500**
Spread across 7–10 years of ownership, that's $150–$360 per year — easily absorbed by the fuel savings.
**Solar owners get an even better deal.** If you have rooftop solar generating excess daytime power, you can charge your EV for effectively $0 during peak solar hours. A 6.6kW solar system can generate enough excess energy to cover 30–60% of average EV charging needs, depending on your household consumption patterns.
**With solar charging factored in, the annual 'fuel' cost for an EV can drop to $200–$400.**
Insurance and Registration: Closing the Gap
EVs have historically been more expensive to insure due to higher purchase prices and specialised repair requirements. However, the gap is narrowing.
**Insurance (comprehensive):** - Toyota Corolla Hybrid: approximately $1,200–$1,500/year - Tesla Model 3 SR: approximately $1,600–$2,100/year - BYD Dolphin: approximately $1,300–$1,700/year
The premium difference is typically $300–$600 per year for an equivalent EV, though this varies significantly by insurer, driver age, and location.
**Registration:** - Most states charge the same registration for EVs as petrol vehicles - Some states (VIC, ACT) offer small EV registration discounts - NSW includes the road user charge separately from registration
**Depreciation:** - EVs historically depreciated faster than petrol cars, but this trend is reversing as demand grows - Popular models like Tesla Model 3 and BYD Atto 3 are holding value well in the Australian resale market - Battery degradation concerns are largely overblown — most modern EV batteries retain 85–90% capacity after 200,000 km
5-Year Total Cost of Ownership Comparison
Let's put it all together for a realistic 5-year comparison based on 15,000 km/year at March 2026 fuel prices.
**Toyota Corolla Ascent Sport (petrol, $29,490 drive-away):** - Fuel (5 years at $2.33/L): $11,885 - Maintenance: $5,000 - Insurance: $7,000 - Registration: $3,500 - Fuel excise (included in fuel price): — - **Total running costs: $27,385** - **Total with purchase: $56,875**
**BYD Dolphin Dynamic ($34,890 drive-away):** - Electricity (5 years, home charging): $3,455 - Maintenance: $2,000 - Insurance: $7,750 - Registration: $3,500 - Road user charge (est. 3.5c/km avg): $2,625 - Home charger install: $1,800 - **Total running costs: $21,130** - **Total with purchase: $56,020**
**5-year running cost saving: $6,255 for the EV**
Remarkably, even though the BYD Dolphin costs $5,400 more to buy, the total cost of ownership over 5 years is actually $855 less than the Corolla. At $3.00/L petrol, the EV advantage widens to over $5,000.
When an EV Doesn't Make Sense (Yet)
EVs aren't the right choice for everyone in 2026 Australia. Here's when petrol still wins:
**Long-distance rural driving:** If you regularly drive 400+ km between towns with limited charging infrastructure, range anxiety is a real concern. The fast-charging network is expanding rapidly along major highways, but coverage in remote and outback areas remains sparse.
**Towing:** EVs lose range dramatically when towing. A Tesla Model Y rated at 455 km range might only achieve 200–250 km towing a caravan. For grey nomads and serious towers, a diesel ute or SUV is still more practical.
**No home charging access:** If you live in an apartment without access to a charging point, you'll rely on public chargers at 50–70c/kWh — roughly halving the cost advantage.
**Very tight budgets:** The cheapest new EVs start around $34,000. If you're buying a $15,000–$20,000 used petrol car, the upfront gap is hard to bridge even with running cost savings.
**For these drivers, a hybrid is often the sweet spot** — combining petrol flexibility with 30–40% better fuel economy. Check our hybrid vs petrol comparison for those numbers.
