What Does It Cost to Charge a Tesla Per Month?

One of the first questions people ask before switching from petrol is a pretty practical one: what's it actually going to cost me each month to keep this thing charged? It's a fair question , and the honest answer is that it depends on how and where you charge. The range runs from almost nothing (if you've got solar) to well over a hundred dollars (if you're living off Superchargers). Most Aussie drivers land somewhere in between.

This guide breaks down every charging scenario you're likely to encounter in Australia , home charging, public networks, and Superchargers , and turns it into real, monthly figures you can actually budget with. We'll also look at how your specific model, your state's electricity rates, and a few smart habits can shift that number considerably.

By the end, you'll have a clear picture of your likely monthly charging spend , and a few practical ways to keep it as low as possible.

The Three Ways to Charge , and Why the Price Varies So Much

Unlike petrol, which costs roughly the same at every servo in a given region, electricity pricing in Australia varies wildly depending on your source, your state, your energy plan, and even the time of day. There are three main charging scenarios for any EV owner, and each comes with a very different price tag.

1. Home Charging , The Cheapest Option

Home charging is where most Aussie EV owners do the bulk of their topping up, and for good reason: it's the cheapest, most convenient, and most predictable option available. You plug in overnight, wake up with a full battery, and start your day without a second thought.

The cost depends on your electricity rate. As of 2026, the average residential electricity rate across Australia sits at roughly $0.30–$0.33 per kWh on a standard tariff, though this varies meaningfully by state. Victorians typically pay at the lower end, while South Australians face some of the highest rates in the country.

Using a standard 57.5 kWh battery (Model 3 or Model Y RWD), a full charge at home costs roughly $17–$19 at the national average rate. For the larger 75 kWh battery in the Long Range variants, that rises to about $22–$25.

2. Public Charging Networks

Australia's public charging network has expanded significantly, with providers like Chargefox, Evie Networks, BP Pulse, and EVX spread across major cities and highways. Pricing typically runs between $0.40 and $0.50 per kWh for AC charging, and higher for DC fast chargers.

For most owners, public chargers are a top-up option rather than a primary source , useful when you're out and about rather than a daily routine. If you rely on them regularly (for example, if you don't have a garage or driveway), your monthly costs will be noticeably higher than a home-charger owner.

3. Tesla Superchargers

Superchargers are the fastest way to charge on the road , capable of delivering up to 250 kW , and there are over 119 Supercharger stations across Australia as of early 2026. They're positioned along major travel corridors and near amenities, making them ideal for road trips.

The trade-off is cost. Supercharger pricing in Australia typically ranges from $0.52 to $0.70 per kWh, with some variation based on location and time of day. That's roughly double the cost of home charging for the same amount of energy. A full charge at a Supercharger can cost anywhere from $30 to $52 depending on your battery size.

The message is clear: if you can do most of your charging at home, your monthly bill stays manageable. The more you rely on Superchargers or public DC chargers, the higher it climbs.

Estimated Monthly Charging Costs , All Scenarios (2026)

Charging Source	Rate (per kWh)	Per Full Charge	Est. Monthly Cost
Home (standard tariff)	~$0.30–$0.33/kWh	$17–$25/full charge	$35–$55/month*
Home (off-peak tariff)	~$0.12–$0.20/kWh	$7–$15/full charge	$15–$30/month*
Home (solar , daytime)	~$0–$0.05/kWh	Near-free	Near-free
Public charger (AC)	~$0.40–$0.50/kWh	$23–$29/charge	$50–$80/month*
Tesla Supercharger	~$0.52–$0.70/kWh	$30–$52/full charge	$65–$120/month*

* Monthly estimates based on the average Australian driving ~1,100 km/month (approx. 37 km/day). Assumes a Model 3 or Model Y RWD with 57.5 kWh battery and real-world efficiency of ~15 kWh/100 km. Your figures will vary.

Charging Costs by Tesla Model , Full Breakdown

The battery size in your specific model is the single biggest variable in how much you'll spend on charging. Bigger battery = more energy needed = higher cost per full charge. Here's how the current Australian line-up compares:

Model	Battery	Range	Home @$0.30	Public @$0.45	Superchgr @$0.70	Est. Monthly
Model 3 RWD	57.5 kWh	~490 km	$17.25	$29.60	$40.25	~$37–55/mo
Model 3 LR AWD	75 kWh	~614 km	$22.50	$33.75	$52.50	~$48–72/mo
Model Y RWD	57.5 kWh	~460 km	$17.25	$25.88	$40.25	~$37–55/mo
Model Y LR AWD	75 kWh	~600 km	$22.50	$33.75	$52.50	~$48–72/mo
Model Y L (6-seat)	~84 kWh	~681 km	$25.20	$37.80	$58.80	~$54–82/mo

* Monthly estimates based on 1,100 km/month average driving and ~15 kWh/100 km real-world efficiency. The Model Y L figure uses an estimated ~84 kWh battery. Costs reflect a home-primary charging approach with occasional public top-ups.

What jumps out from those numbers is how significant the gap between home and Supercharger pricing is. The difference isn't small , for a Model Y Long Range owner doing 1,100 km per month, home charging costs around $48–$72 per month, while relying entirely on Superchargers would push that to $120 or more. Most real-world drivers use a mix, which tends to land costs in the $55–$85 range.

How Your State Affects What You Pay

Electricity pricing in Australia is not uniform , it varies significantly by state and territory, which has a direct impact on what you'll spend charging at home. South Australians pay the most; Victorians and Tasmanians typically pay the least.

State	Avg. Home Rate	Cost Per Full Charge	Est. Monthly (Home)
NSW	~$0.28–$0.36/kWh	~$16–$21 per full charge	~$35–$48/month
VIC	~$0.24–$0.32/kWh	~$14–$18 per full charge	~$30–$42/month
QLD	~$0.26–$0.34/kWh	~$15–$20 per full charge	~$33–$45/month
SA	~$0.38–$0.48/kWh	~$22–$28 per full charge	~$48–$62/month
WA	~$0.30–$0.38/kWh	~$17–$22 per full charge	~$38–$50/month

* Based on average standard residential tariffs as of early 2026 (Canstar, Finder). Monthly estimate assumes 1,100 km/month and a 57.5 kWh battery at ~15 kWh/100 km. Rates vary by provider and plan.

If you're in South Australia and relying on the standard grid rate, your home charging bill alone could be $48–$62 a month. A Victorian on a competitive plan, meanwhile, might spend as little as $30 on the same driving distance. The lesson here is that shopping around for a better energy plan before or shortly after buying your EV is genuinely worth doing.

Worth Knowing: Time-of-Use Tariffs

Many Aussie electricity plans offer off-peak rates between 10pm and 7am , often $0.12–$0.20 per kWh rather than the standard $0.30+. Scheduling your car to charge overnight using the Tesla app can cut your home charging bill roughly in half.

How Solar Changes Everything

If you've got a rooftop solar system , and a growing number of Australians do , the monthly charging equation changes dramatically. Charging your car from excess solar generation during the day can cost next to nothing, or at the very least significantly reduce what you'd otherwise spend on grid electricity.

Charging During the Day from Solar

For drivers who work from home, retire early, or can plug in during daylight hours, daytime solar charging is essentially free , you're using power you've generated yourself rather than drawing from the grid. A typical residential solar system in Australia generates 15–25 kWh on a good day, which can fully or partially cover the energy needed to top up a Model 3 or Model Y RWD.

Even partial solar coverage makes a meaningful difference. Charging 50% from solar and 50% from grid power on an off-peak tariff can drop your monthly charging cost to under $15 in favourable conditions.

Solar + Battery Storage

Owners with both solar panels and a home battery (like a Tesla Powerwall) can take this further , storing excess solar generation during the day and using it to charge the car overnight. This setup is the most cost-effective long-term, though the upfront investment in storage adds to the overall ownership cost.

The financial case is stronger than ever in 2026 given that feed-in tariffs (what you earn selling excess solar back to the grid) are very low in most states , in many cases under $0.05 per kWh. Storing that energy and using it to charge your car instead is far more valuable than selling it back at those rates.

"Even when using a conservative 80% estimate of the WLTP range, a Tesla Model Y is up to 68% cheaper per kilometre than a comparable petrol car , even when using Superchargers."

The Monthly Cost in Real-World Terms

Let's bring all of this together with a practical example for the average Aussie driver. According to industry data, Australians drive roughly 37 km per day , about 1,100 km per month. Here's what that looks like across three different charging setups for a Model Y RWD owner:

Scenario 1: Home Charger Only (Standard Tariff)

1,100 km × 15 kWh/100 km = 165 kWh per month. At $0.30/kWh: approximately $49.50/month. Annual cost: ~$594.

Scenario 2: Home Charger on Off-Peak Tariff

Same 165 kWh usage. At $0.16/kWh off-peak rate: approximately $26.40/month. Annual cost: ~$317. The saving over standard tariff: over $270 per year.

Scenario 3: Mixed (70% Home + 30% Supercharger)

115.5 kWh at home @ $0.30 = $34.65 | 49.5 kWh at Supercharger @ $0.60 = $29.70. Total: approximately $64.35/month. Annual cost: ~$772.

Compare any of those figures to the average Australian petrol spend. A survey from Budget Direct found the average Aussie spends over $70 filling up a single time , and most do that more than once a month. Even the most expensive EV charging scenario above sits well below typical monthly petrol costs.

Ways to Reduce Your Monthly Charging Bill

There's no shortage of ways to trim what you spend on electricity each month. Some of these will have a bigger impact than others depending on your setup, but even a few of them in combination can make a real difference.

Practical Ways to Lower Your Monthly Charging Cost

✓  Switch to a time-of-use electricity plan and set your car to charge between 10pm and 7am , off-peak rates can be as low as $0.12/kWh.

✓  Use the Tesla app's scheduled charging feature: set a departure time and let the car decide when to start charging for cheapest rates.

✓  If you have solar, charge during peak generation hours (10am–3pm) rather than overnight whenever possible.

✓  Keep your charge limit set to 80–90% for daily use , only charge to 100% before long road trips. This preserves battery health and uses less energy.

✓  Precondition the cabin while still plugged in at home (in summer or winter) , warming or cooling the car on grid power before driving means the battery does less work on the road.

✓  Compare electricity providers on the AER's Energy Made Easy website before you commit to a plan , the difference between the best and worst offer can be significant.

✓  On road trips, top up at Superchargers to 80% only , charging slows significantly above 80%, and you'll move faster if you charge to 80 and stop more frequently.

✓  Look out for free destination chargers at hotels, restaurants, and shopping centres , they won't give you a full charge quickly, but they can top up for nothing if you're parked for a few hours.

Charging Costs vs Petrol , The Honest Comparison

The running cost comparison between an EV and a petrol car is often presented in the best possible light by EV advocates , and sometimes that involves cherry-picking numbers. Here's an honest version, using real 2026 figures for the Australian market.

A Toyota Camry SX petrol doing 1,100 km per month at its combined fuel economy of 4.7L/100 km would consume about 51.7 litres. At the average Sydney petrol price of around $2.00/litre in early 2026, that's roughly $103.40 per month in fuel alone , not counting servicing, oil changes, and other mechanical costs.

A Tesla Model Y RWD doing the same 1,100 km on a standard home tariff of $0.30/kWh costs roughly $49.50 per month. On an off-peak tariff, that drops to around $26. With solar contributing even part of the charge, it could be under $15.

The savings are real, meaningful, and compound over time , particularly as petrol prices remain volatile and electricity plans offer more flexibility. Even the worst-case EV charging scenario (heavy Supercharger use at $0.70/kWh) comes in cheaper than average petrol costs for the same distance.

Frequently Asked Questions

Q1: Does charging a Tesla significantly increase my home electricity bill?

Yes, but probably less than you'd expect. Adding a Tesla to your home electricity consumption increases your usage , but if you charge on an off-peak tariff overnight, the extra cost can be surprisingly modest. Based on the average Australian driving 1,100 km per month at 15 kWh/100 km, you're adding roughly 165 kWh of electricity consumption per month. At the average residential rate of $0.30/kWh, that's about $49.50 extra on your bill. On a good off-peak rate of $0.16/kWh, it drops to around $26. In practical terms, many owners find their electricity bill increases by $40–$70 per month while their petrol spend drops to zero , which is almost always a net saving.

Q2: Is it cheaper to charge at a Supercharger or at home?

Home charging is almost always cheaper , usually by a significant margin. As of 2026, Australian Superchargers typically charge between $0.52 and $0.70 per kWh, while home electricity rates average around $0.30/kWh on a standard tariff, or as low as $0.12–$0.20/kWh on an off-peak plan. For a full charge of a Model Y RWD (57.5 kWh), that's $17–$19 at home versus $30–$40 at a Supercharger. Superchargers are best thought of as a road trip tool , fast, convenient, and worth the extra cost when you need to cover distance quickly. For daily charging, home is always the better financial choice.

Q3: How do I work out what my specific monthly charging cost will be?

The simplest formula: (km driven per month ÷ 100) × (your car's energy consumption in kWh/100 km) × (your electricity rate in $/kWh). For a Model Y RWD doing 1,100 km/month at 15 kWh/100 km on a $0.30/kWh tariff: (1,100 ÷ 100) × 15 × 0.30 = $49.50/month. Your car's real-world consumption will vary based on speed, climate, how you drive, and how much AC or heating you use , so the official WLTP figure is a starting point rather than a guarantee. The Tesla app tracks your real energy usage over time, which gives you the most accurate figure to plug into the formula once you've been driving for a month or two.

The Bottom Line

For most Aussie EV owners charging primarily at home, monthly electricity costs sit in the $30–$65 range , far less than the petrol bill for a comparable size vehicle. Push that down with an off-peak tariff or solar panels, and it drops further still. Rely heavily on Superchargers, and you'll pay more , but still likely less than petrol for the same kilometres.

The exact number depends on your model, your state's electricity rates, how much you drive, and how smart you are about when and where you charge. The good news is that all three of those levers are within your control , and even a few simple habits (scheduled overnight charging, staying at 80% for daily use) can meaningfully reduce what you spend each month.

If you're still on the fence about switching, run the numbers with your actual driving distance and your current petrol spend. For the overwhelming majority of Australian drivers, the maths strongly favours the switch , and the charging cost is rarely the stumbling block it's feared to be.
