Australia crossed 100,000 registered EVs in 2024. By early 2026, that number has grown substantially — and with it, a more grounded, data-driven conversation about whether the switch actually makes financial sense.
The honest answer: for most Australian drivers, an EV is now cheaper to own over five years than an equivalent petrol vehicle. But the breakeven timeline varies significantly based on how you drive, where you charge, and how you finance the purchase.
Here is the full picture.
The Four Cost Categories That Determine the Real Answer
1. Fuel vs Electricity
The average Australian drives approximately 14,000 km per year. At current petrol prices around $2.05/litre, a mid-size petrol SUV averaging 9.5L/100km costs roughly $2,727 per year in fuel.
An equivalent electric SUV using 18 kWh/100km, charged primarily at home at $0.30/kWh, costs approximately $756 per year — a saving of just under $2,000 annually.
If you charge with rooftop solar, your electricity cost can drop to near zero during the day. EV owners with solar report fuel-equivalent costs as low as $150–$300 per year.
Pro Tip: If you're considering an EV and own your home, factor solar charging into your total cost of ownership analysis. The combination can accelerate your payback period from 4–5 years to 2–3 years.
At public fast chargers (NRMA, Chargefox, BP Pulse), costs typically run $0.45–$0.65/kWh, which narrows the fuel saving significantly. If you can't charge at home or work, the electricity cost equation changes materially.
2. Servicing and Maintenance
This is where EVs deliver their most consistent financial advantage. A petrol engine has over 2,000 moving parts. An electric drivetrain has fewer than 20.
Typical annual servicing comparison:
- Petrol — $600–$900/year (oil changes, filters, spark plugs, coolant, timing belt at high km)
- EV — $250–$400/year (brake fluid, cabin air filter, tyre rotation, software updates)
Brakes on EVs last significantly longer due to regenerative braking — some EV owners report original brake pads still in service at 150,000+ km. Over a 5-year, 70,000 km ownership period, servicing savings can amount to $1,500–$2,500.
Battery warranties are now standardised at 8 years / 160,000 km across most major manufacturers (Tesla, BYD, Hyundai, Kia, Toyota). This materially reduces the perceived risk of battery degradation.
3. Registration, LCT, and Government Incentives
Luxury Car Tax (LCT) threshold for fuel-efficient vehicles (defined as using less than 7L/100km petrol equivalent) is $89,332 for the 2025–26 financial year — compared to $76,950 for standard petrol vehicles. Many EV models that would otherwise attract LCT fall under the higher threshold.
Pro Tip: If you're considering an EV priced between $76,950 and $89,332, check the manufacturer's stated fuel consumption equivalent carefully. Falling under the fuel-efficient LCT threshold can save you thousands — use our Luxury Car Tax calculator to model the exact figure.
FBT exemption: EVs priced under the luxury car tax threshold that are provided through a novated lease or employer arrangement are currently exempt from Fringe Benefits Tax (FBT) in Australia. For salary-package employees, this can reduce the effective cost of an EV by 30–47% depending on marginal tax rate. This exemption does not apply to plug-in hybrids from 1 April 2025.
State-based incentives vary significantly. Check current programs in your state before finalising your decision, as these have been updated frequently.
4. Depreciation
Historically, depreciation has been the EV's weak point. First-generation EVs — particularly the early Nissan Leaf and early Tesla Model 3 — depreciated faster than equivalent petrol vehicles as battery technology improved rapidly.
The market has stabilised. Newer EVs from established manufacturers are retaining value comparably to petrol equivalents in most segments. However, depreciation risk remains higher for:
- Entry-level EVs from emerging brands without established parts networks
- Long-range variants of mainstream models where battery improvements are frequent
- Any EV purchased new in a segment about to receive a major model update
A 2026 purchase consideration: If buying new, factor in how competitive the segment will look in 3–5 years. Tesla, BYD, Hyundai/Kia, and Toyota now have stable depreciation profiles across most of their EV ranges.
The 5-Year Total Cost of Ownership: A Real Comparison
The following is modelled on a $55,000 mid-size SUV (petrol) vs a $65,000 equivalent EV, financed over 5 years at 7.5% p.a., driving 14,000 km/year, home charging at $0.30/kWh.
| Cost Category | Petrol (5yr) | EV (5yr) |
|---|---|---|
| Purchase price | $55,000 | $65,000 |
| Loan repayments (total) | $65,820 | $77,940 |
| Fuel / electricity | $13,635 | $3,780 |
| Servicing | $3,750 | $1,500 |
| Registration | $3,500 | $3,200 |
| Total 5-year cost | $86,705 | $86,420 |
At current prices, the total 5-year cost is approximately breakeven — with the EV marginally ahead. Factor in the FBT exemption for novated lease purchasers and the EV wins by $10,000+. Factor in solar charging and the EV wins by $5,000–$8,000 more.
Pro Tip: The financing rate on your EV loan has a direct impact on the breakeven timeline. A 1.5% lower interest rate on a $65,000 loan over 5 years saves approximately $2,500 — shifting the EV from marginal to clearly ahead.

Run Your Own Numbers
The averages above mask significant variation. Your result depends on:
- Your daily commute distance and charging access
- Whether you have solar panels or can install a home charger
- The specific vehicles you're comparing
- Your marginal tax rate (for FBT/novated lease scenarios)
- Your financing rate
Our EV savings calculator lets you input your actual numbers — annual km, home electricity rate, petrol consumption — and returns a year-by-year cost comparison. It's the fastest way to make the general numbers personal.
Financing the Switch: Don't Overlook the Loan Rate
The EV purchase price premium is the most cited barrier to switching. What's less discussed is that the interest rate on your EV loan directly affects the payback period.
Most Australian car buyers finance through a dealership. Dealership finance routinely carries rates 2–4% above what's available from specialist lenders. On a $65,000 loan over 5 years, a 3% rate difference costs approximately $4,900 in additional interest.
ClariFi compares car loans from 50+ lenders, including specialist green vehicle lenders who offer reduced rates specifically for EVs and PHEVs. A lower rate on your EV loan closes the purchase price gap faster and shortens your payback period.

Key Takeaways
- Over 5 years, EVs are at or near cost parity with equivalent petrol vehicles at current Australian fuel prices
- Home charging is essential for maximum savings — public charging narrows the advantage significantly
- Servicing savings are consistent and meaningful: $1,500–$2,500 over 5 years
- The FBT exemption for novated leases makes EVs significantly cheaper for salary-packaging employees
- The LCT fuel-efficient threshold gives EVs a tax advantage on vehicles priced $76,950–$89,332
- Depreciation risk has reduced but remains a consideration for entry-level and emerging-brand EVs
- Your financing rate matters — don't pay dealership rates on a $65,000 purchase
