Tesla Supercharger costs, explained
There's no single "Supercharger price". It changes by site and often by time of day. Here's how to find the real price before you plug in, and how to turn it into a cost per km.
Where to see the price
Tap a Supercharger on the car's map or in the Tesla app and it shows the current price. Check before you go. Prices can be different at another site down the road, and many sites charge different rates at different times of day.
How you're charged
Supercharging is billed by energy, in kilowatt-hours (kWh). Your session cost is roughly:
kWh added × price per kWh at that site and time
The session shows up in the Tesla app afterwards.
Fees to know about
- Idle fees: if your car's finished charging and you leave it plugged in while the site is busy, you can be charged per minute. The app tells you when you're nearly done, so move the car.
- Congestion fees: some busy sites charge extra when they're crowded, and the app shows it. We saw them in 5 of our 70 SEQ sessions.
What our fleet actually paid (real data)
Across 70 Supercharger sessions by 10 of our cars in South East Queensland (20 Sep–12 Oct 2026):
| Price per kWh | |
|---|---|
| Range seen | A$0.31–0.60 |
| Median | A$0.48 |
| Off-peak (before ~8–9 am, late night) | A$0.31–0.34 |
| 10 am–4 pm (median) | A$0.55 |
| 4–9 pm (median) | A$0.48 |
A typical session added about 30 kWh in about 25 minutes for about A$12.34 (median). Most sessions landed between A$5.70 and A$21.91. Congestion fees hit 5 of the 70 sessions (A$2.50–A$30).
Tip first: Supercharge early in the morning or late at night if you can. Punchline: your mate who still queues at the servo at 5 pm on a Friday is paying peak prices for petrol and for the privilege.
Prices change. Always check the app before you plug in.
Turn it into cost per km
Your car's energy screen shows your average consumption (Wh/km). Use that to estimate cost per km:
cost per km ≈ (Wh/km ÷ 1,000) × price per kWh
For example, a Model Y using 170 Wh/km at A$0.48/kWh costs about 8c a km in charging. Off-peak home charging usually beats Supercharging, so charge at home when you can and save the Supercharger for when time matters.
Make Supercharging quicker (and so cheaper in time)
- Navigate to the Supercharger in the car, so the battery warms up on the way.
- Arrive low and leave around 80%. The top of the battery charges slowest.
- Don't wait for 100% on a busy site unless you really need it.
On a Charge Drive plan
Charging costs are yours on prepaid km plans, and our cars can use Superchargers, billed per use. Your km pack covers the car. Charging is the "fuel" part.
