TESLA CHARGING · CHECKED 22 OCTOBER 2026
What does it cost to charge a Tesla?
For a 250 km week, our 2025 Tesla Model Y RWD example costs $12.67 at the Ausgrid NSW reference rate of 33.1c/kWh. Your exact configuration and electricity rate matter more than the badge.

Model 3 and Model Y, on the same assumptions
Each row is a verified release configuration, not a statement that every version is available to buy today. Certified energy consumption is held constant across the three scenarios. The public 65c/kWh and solar 5c/kWh figures are illustrative inputs, not quoted Tesla prices. All rows exclude extra session fees.
| Configuration | Wh/km | Home / week | Solar 5c / week | Public 65c / week |
|---|---|---|---|---|
| Tesla Model Y RWD · 2025 | 153 | $12.67 | $1.91 | $24.86 |
| Tesla Model 3 Long Range RWD (18-inch) · 2025 | 125 | $10.36 | $1.56 | $20.31 |
| Tesla Model 3 RWD (H6LRB) · 2023 | 132 | $10.94 | $1.65 | $21.45 |
Home costs use the Ausgrid 2026–27 residential reference. NSW has multiple distribution zones and your market offer can differ. Change the zone, rate and weekly distance in the calculator to make the comparison relevant.
What will a Supercharger charge?
Tesla displays site pricing in its app or vehicle screen. Check the specific location and plug-in time. Its Supercharging guidance explains time-dependent pricing and possible congestion charges. Tesla owners and eligible non-Tesla members can have different pricing from non-members; an app price for one account does not establish every driver’s rate.
We have not filled this table with an invented national Supercharger average. Use a current station rate and membership conditions from the app, and add applicable fees. The public pricing register distinguishes verified samples from prices that require an app check.
How much is a full battery?
A weekly driving estimate and a battery top-up answer different questions. Weekly energy uses distance and consumption. A session uses usable capacity multiplied by the change in state of charge. Charging from 10% to 100% adds 90% of usable capacity, before additional metered energy losses.
Tesla does not provide a verified usable-capacity figure for every exact configuration in this register. Unknown capacity stays “Not stated”. For a real session, multiply the billed kWh on the receipt by the applicable rate. Do not infer usable capacity from the model name, nominal pack size or advertised driving range.
Home power and charging time
The wall unit’s rating is only one limit. Your car, supply connection and installed circuit can also limit power. Follow Tesla’s Australian Wall Connector guidance and have a licensed electrician assess the installation. Our time calculator uses an average power into the battery, so it does not treat a Supercharger’s peak label as a sustained charging rate.
Choose a daily charging target using the car’s guidance. Battery chemistry, temperature, starting percentage and the charging curve affect the session. A faster charger does not automatically make a higher per-kWh price economical for every stop.
Use your actual mix
If most charging happens at home and only occasional trips use Superchargers, a public-only scenario overstates your normal week. Use mixed mode to assign the share of energy bought publicly. If the car is home during solar production, compare the export income forgone with the overnight import rate. Include a membership subscription only when the saving on your actual public energy outweighs its cost.
