EV Charging vs Petrol: What It Really Costs in Australia

Ask a room full of EV owners whether they'd go back to petrol and you'll get a chorus of "never." Ask them what it costs to charge, though, and the answers scatter — because charging isn't one price. It's a spectrum that runs from almost free to more expensive than a fuel-efficient petrol car, and the number you land on comes down to your own driving and where you charge. That's the part the "EVs are so cheap!" headlines skip, so let's do it properly.

What petrol actually costs you in 2026

Start with the thing you already pay for. Across the capital cities, unleaded has spent 2026 bouncing between roughly $1.85 and $2.20 a litre, and regional drivers routinely pay 10–20 cents more. Call it $2.00 as a fair working number.

A mid-size sedan sipping 8 litres per 100 km therefore costs about $16 per 100 km, or 16 cents a kilometre. Drive the Australian average of 15,000 km a year and that's roughly $2,400 a year in fuel alone. Step up to a thirsty SUV at 10–12 L/100 km and you're closer to $3,300–$3,960. None of that includes the servicing a combustion engine demands — more on that later. Petrol is the expensive habit you've stopped noticing.

What charging costs — the three tiers

Here's where EVs get interesting, because "charging" covers three very different price bands. A typical EV uses about 16 kWh per 100 km (a small hatch nearer 14, a big dual-motor SUV closer to 22), so we'll use 16 to convert cents-per-kWh into cents-per-kilometre.

Read that table twice, because it's the whole story. Charge at home overnight on an off-peak or dedicated EV tariff and you're running the car for around 3 cents a kilometre — roughly a fifth of petrol. Some retailers offer EV plans as low as 8c/kWh, which is genuinely close to free motoring. Add rooftop solar and the marginal cost of the kilowatt-hours you'd otherwise export drops to almost nothing.

Public charging is a different animal. On the major DC fast networks, 2026 rates commonly sit in the 45–80c/kWh band — Chargefox around 45–65c, Evie a touch higher, and Tesla Superchargers at the premium end, often near 70–79c and sometimes with an idle fee (around $1/minute if you leave the car plugged in after it's full). Ampol's AmpCharge sites run big 150 kW+ speeds around 60c with no idle fee. Destination AC chargers at shopping centres, hotels and kerbsides are often the cheapest public option, sometimes 25–45c, occasionally free.

The honest catch: where you plug in decides everything

This is the part worth being straight about, because it's the difference between "EVs saved me thousands" and "I'm not sure it was worth it." The savings are real and large if you can charge at home, on the right tariff, most of the time — which is how 80–90% of owners actually charge.

But if you live in an apartment with no home charger and rely on public DC fast charging, the maths tightens. At 70c/kWh, that same 16 kWh/100 km car costs about $11.20 per 100 km — still under petrol's $14–16, but no longer the jaw-dropping saving the headlines promise. Lean on premium rapid chargers for a thirsty EV and the gap to a small, efficient petrol car can nearly close.

One genuine upside even for public charging: in Australia the chargers tend to sit near shops, cafes and attractions rather than out at a highway servo, so the 20–40 minutes you spend topping up is usually time you'd have spent anyway. It's a nicer errand than standing at a bowser.

It's not just fuel: servicing, rego & depreciation

Running cost is more than what goes into the "tank." Over years of ownership, the other lines matter:

• Servicing is much cheaper. No oil changes, spark plugs, timing belts or exhaust; fewer than 20 moving parts in the drivetrain, and regen braking that spares the brake pads. Expect roughly $150–$300 a year versus $400–$800 for a petrol car — a 50–70% drop, and around $2,000–$3,500 saved over five years.
• Registration is broadly comparable to an equivalent petrol car in most states in 2026, so it's rarely the deciding factor.
• Novated leasing can be a big lever. Eligible EVs under the luxury-car threshold still attract the fringe-benefits-tax exemption, which can make a lease dramatically cheaper than owning outright — worth investigating if you're employed and salary-packaging.
• Rebates vary and are shrinking. Some state incentives have ended and others continue; check what's current in your state rather than assuming.
• Depreciation is the honest risk. EV resale values have been more volatile than petrol as the market matures and prices fall. Buy sensibly, and don't count on running-cost savings alone if you plan to sell in a year or two.

Add it up and, for most buyers, the total cost of ownership crosses below the equivalent petrol car somewhere between two and four years — sooner if you drive a lot, have solar, or charge at work.

A 5-year example: EV vs petrol

Numbers beat adjectives, so here's a like-for-like comparison with every assumption stated: 15,000 km a year, a mid-size EV at 16 kWh/100 km charged at home off-peak (20c/kWh), versus an equivalent petrol car at 8 L/100 km and $2.00/L.

That's roughly $2,270 a year, or about $11,000 over five years, in running-cost savings — enough to offset most of the price premium EVs still carry over petrol equivalents. Swap in public-fast-charging prices instead of home off-peak and the fuel line jumps from ~$480 to ~$1,700+, which is exactly why your charging situation is the number that matters most.

How to keep your EV cheap to run

The drivers who save the most aren't lucky — they just pull a few obvious levers:

• Charge at home overnight on a time-of-use or dedicated EV tariff. This single move is where nearly all the savings live.
• Add solar if you can, and top up in the middle of the day to soak up what you'd otherwise export.
• Use free and destination AC charging when you're parked at the shops or a hotel anyway.
• Reserve DC fast charging for road trips, not daily driving — it's for convenience, not economy.
• Compare network prices before you plug in. Public rates vary a lot between operators for the same energy, and avoiding idle fees and premium sites keeps your average cost down.

That last point is the one most people miss — and it's exactly what Plugroo is built to make easy.

So, should you make the switch?

If you can charge at home, the running-cost case is close to a no-brainer: you'll likely spend a fifth of what petrol costs you, save another few hundred a year on servicing, and break even on the price premium within a few years. For a household doing average kilometres, that's four figures back in your pocket every year — money that only grows as fuel prices climb.

If you can't charge at home yet, don't write it off — public charging is usually still cheaper than petrol, and it's getting easier. Just go in with your eyes open: work out your likely charging mix, lean on destination and off-peak options, and use a good app to always find the cheapest working charger nearby. Do that, and the "EVs are cheaper" promise holds up in the real world, not just the brochure.

Key takeaways

1. Petrol at ~$2.00/L costs a mid-size car about $14–16 per 100 km, or roughly $2,400 a year at average kilometres.
2. Home off-peak charging runs around 3 cents a kilometre — about a fifth of petrol — and solar gets it close to free.
3. Public DC fast charging (45–80c/kWh) is convenient but pricey; at the top end an EV's cost per km can approach a small petrol car.
4. Where you charge 80% of the time is the number that decides whether you save thousands or just a little.
5. Beyond fuel, EVs save 50–70% on servicing; rego is broadly comparable; watch depreciation, and check novated-lease FBT savings and any current rebates.
6. Most buyers reach total-cost break-even in 2–4 years — sooner with home charging, solar or high mileage.
7. Charge smart: home off-peak, destination AC, and compare network prices to keep every kilometre cheap.
