EV vs Petrol: Real Cost Right Now
At $2.50/L, a petrol commuter spends $5,000+/yr on fuel. An EV costs ~$700/yr in electricity. Here's the full comparison.

Fuel cost comparison: petrol vs EV
Let's cut straight to the numbers. A typical Australian drives about 15,000km per year. Here's what it costs to fuel that driving:
| Petrol car | Electric car | |
|---|---|---|
| Efficiency | 8.5L/100km | 15kWh/100km |
| Energy needed/yr | 1,275L | 2,250kWh |
| Cost per unit | $2.50/L | $0.30/kWh |
| Annual fuel cost | $3,188 | $675 |
| Annual saving | $2,513 with EV | |
That's $2,513 a year in fuel savings alone. Even with the temporary excise cut bringing petrol down, you're still paying over $2,800/yr vs $675 for electricity.
Over 5 years at these prices, that's $12,565 saved on fuel. Over 10 years, $25,130. And electricity prices are far more stable than petrol — you're not at the mercy of Middle Eastern conflicts and OPEC decisions.
But EVs cost more upfront
True. The average EV in Australia costs around $50,000 (think BYD Atto 3, Tesla Model 3, MG4). A comparable petrol car sits around $35,000. That's a $15,000 gap.
At $2,513/year in fuel savings, the breakeven is about 6 years. If fuel stays at $2.50+ (which looks likely with the Iran situation), it's closer to 5 years.
But there's more to the equation:
- Servicing: EVs have far fewer moving parts. No oil changes, no transmission servicing, no exhaust system. Average EV servicing is $300-500/yr vs $800-1,200 for petrol.
- Rego: Some states offer EV rego discounts (ACT, for example)
- Resale: EV resale values have stabilised and are now comparable to petrol equivalents
Factor in servicing savings of ~$500/yr, and the breakeven drops to under 5 years.
Charging costs: home vs public
Not all electricity is created equal when it comes to EV charging:
| Charging method | Cost per kWh | Cost per 100km | Annual cost (15,000km) |
|---|---|---|---|
| Home — off-peak overnight | $0.15-0.20 | $2.25-3.00 | $338-450 |
| Home — standard rate | $0.25-0.35 | $3.75-5.25 | $563-788 |
| Public fast charge | $0.50-0.65 | $7.50-9.75 | $1,125-1,463 |
| Home solar | $0.00-0.05 | $0.00-0.75 | $0-113 |
The golden setup is charging overnight on an off-peak tariff, or during the day if you have solar panels. Some EV owners with decent solar systems are essentially driving for free.
Even using public fast chargers exclusively (worst case), an EV is still cheaper than petrol at current prices — $1,463/yr vs $3,188/yr.
Novated lease: the EV tax loophole
Here's where EVs get really interesting financially. Under the current rules, electric vehicles under $91,387 are exempt from Fringe Benefits Tax when salary packaged through a novated lease.
This means you can pay for your EV from your pre-tax salary, saving you your marginal tax rate on every dollar. For someone earning $100K, that's a 32.5% saving (plus 2% Medicare) on the lease payments, running costs, and insurance.
A $50,000 EV on a novated lease effectively costs more like $34,000-38,000 after tax savings. Combined with the fuel savings, the total cost of ownership is significantly less than a comparable petrol car.

Is now the right time to switch?
The honest answer depends on your situation:
Switch now if:
- You're spending $50+ per week on fuel
- Your current car is due for replacement anyway (5+ years old, high km)
- You have home charging available (garage, carport, driveway)
- You can access a novated lease through your employer
- You do most of your driving in the city or suburbs (range anxiety is a non-issue for daily commutes)
Keep your petrol car if:
- It's relatively new and running well
- You regularly drive long distances in regional areas with limited charging
- You don't have access to home charging and would rely on public chargers
- The upfront cost would put you into financial stress
If you're keeping your petrol car, claim your fuel tax deductions and use our fuel savings calculator to find every way to cut costs.
