How we calculated this
- The energy the car uses over a set distance comes from its Green Vehicle Guide figure.
- Each share of charging is priced at its own rate: home, an EV night plan, public fast chargers and your own solar.
- The petrol car is priced from its fuel use and the price per litre. The yearly saving is the gap between the two.

Tesla Model Y: what to know
Official source
- The Green Vehicle Guide lists the 2025 Model Y at 158 to 162 Wh/km, depending on the variant. That is 15.8 to 16.2 kWh per 100 km, measured at the wall.
Not yet checked
- Tesla owners were reported to pay from 27c/kWh off-peak at one Supercharger site (Braybrook VIC, before 8am). Reported by The Driven, read on 23 September 2026. Prices vary by site: check the app.
| Car | All at home | 20% fast | 50% fast | All fast |
|---|---|---|---|---|
| Tesla Model Y 2025 AWD 600 km | $641 | $793 | $1,022 | $1,402 |
| Tesla Model Y 2025 AWD 551 km | $637 | $788 | $1,015 | $1,394 |
| Tesla Model Y 2025 Performance | $653 | $808 | $1,041 | $1,429 |

- For the Tesla Model Y 2025 AWD 600 km, each 10% of charging moved from home to a fast charger adds about $76 a year: $641 with all of it at home at 32c/kWh, $1,402 with all of it at fast chargers at 70c/kWh.
- Fast charging would have to cost about 166c/kWh before the Tesla Model Y 2025 AWD 600 km cost as much per 100 km as the average petrol car ($26.36). Our estimate is 70c/kWh.
- The 4 Tesla models in our list use 15.8 to 16.5 kWh per 100 km. With all charging at home, a year costs $637 for the Tesla Model Y 2025 AWD 551 km and $665 for the Tesla Model 3 2025.
Each cell is a year of charging from the calculator on this page: 12,600 km a year (Official source), with fast charging at 70c/kWh (Estimate). Home charging is at our plain average of the state default rates, 32c/kWh. The state rates are: Dated third-party source, except Western Australia (Official source). Home and fast charging are priced on the same energy use: each car's Green Vehicle Guide figure, measured at the wall (Official source). That figure already counts what is lost in charging, so no charging loss is added to either.
What one charge of a Model Y costs
One charge of the Model Y AWD 600 km at home
Usable battery of the Tesla Model Y 2025 AWD 600 km: 79 kWh.
Source: ev-database usable battery for the Model Y Premium AWD (82.0 kWh nominal). The Green Vehicle Guide lists this car only as AWD, 600 km, and no page ties it to a trim, so the battery is our pick. Tesla Australia publishes no kWh figure (Estimate). Checked 30 September 2026.
Charging it from 10% to 80% puts 55.3 kWh in the battery. At home that takes about 61.9 kWh from the wall, with 12% lost on the way in (Estimate), and adds about 390 km. That one charge costs about $19.82 at 32c/kWh, or $4.34 on an EV night plan at 7c/kWh.
One fast charge of the Model Y AWD 600 km
Fast-charge time of the Tesla Model Y 2025 AWD 600 km: 10% to 80% in 28 minutes on a 250 kW charger.
Source: ev-database, Model Y Premium AWD: 10 to 80% in 28 min on a 250 kW V3 Supercharger. The trim is our pick (see the battery figure) (Estimate). Checked 30 September 2026.
That session puts 55.3 kWh in the battery, about 390 km of driving. The calculator on this page prices fast charging on the same energy figure as home charging, the car's Green Vehicle Guide figure, which is measured at the wall. So at 70c/kWh those 390 km cost about $43.36, against about $19.82 at home at 32c/kWh. The same charge on a 7 kW wall charger takes about 8 h 25 min.

Questions
How much does a Tesla Supercharger cost?
It changes by site and time of day. Tesla owners were reported to pay from 27c/kWh off-peak at one Supercharger site (Braybrook VIC, before 8am). Reported by The Driven, read on 23 September 2026 (Not yet checked). Check the Tesla app, then type the rate as your fast-charging price.
Is it cheaper to charge a Model Y at home?
At our fast-charging estimate, yes. The Tesla Model Y 2025 AWD 600 km costs about $5.09 per 100 km at our average home rate of 32c/kWh, against $11.13 at 70c/kWh. The EV night plans we checked are 4.5c to 8c/kWh, lower again. Not at every Supercharger, though: the lowest price reported for Tesla owners, 27c/kWh at Braybrook VIC before 8am (Not yet checked), is under our average home rate.
