Tesla Supercharger Cost Guide
How much does it really cost to charge a Tesla? Live Supercharger benchmarks vs home charging, broken down by model and state.
The short answer
Tesla Superchargers in the US average roughly $0.36/kWh for Tesla owners and $0.46/kWh for non-Tesla EVs (Magic Dock / NACS guest access). At those rates a full charge on a 75 kWh Model 3 or Model Y costs about $20–$35. Home charging at the US residential average of $0.17/kWh is roughly half that.
Cost per full charge by model
Assuming 10% → 100% Supercharging at the US member rate ($0.36/kWh) vs home charging at $0.17/kWh.
| Model | Battery | Supercharger | Home | Savings |
|---|---|---|---|---|
| Model 3 Long Range | 75 kWh | $24.30 | $11.48 | $12.82 |
| Model Y Long Range | 75 kWh | $24.30 | $11.48 | $12.82 |
| Model S | 95 kWh | $30.78 | $14.54 | $16.24 |
| Model X | 95 kWh | $30.78 | $14.54 | $16.24 |
| Cybertruck AWD | 123 kWh | $39.85 | $18.82 | $21.03 |
Cost per mile: Supercharger vs home
Using EPA combined efficiency for each model. Cost per mile = $/kWh ÷ mi/kWh.
| Model | mi/kWh | Supercharger ¢/mi | Home ¢/mi | Per 100 mi (SC) |
|---|---|---|---|---|
| Model 3 Long Range | 4.0 | 9.0¢ | 4.3¢ | $9.00 |
| Model Y Long Range | 3.6 | 10.0¢ | 4.7¢ | $10.00 |
| Model S | 3.5 | 10.3¢ | 4.9¢ | $10.29 |
| Model X | 3.0 | 12.0¢ | 5.7¢ | $12.00 |
| Cybertruck AWD | 2.3 | 15.7¢ | 7.4¢ | $15.65 |
Supercharger rates by state
Tesla adjusts prices by station based on local wholesale power and demand. These are estimated state averages for member (Tesla) and guest (non-Tesla) rates.
| State | Member $/kWh | Guest $/kWh | vs US avg |
|---|---|---|---|
| California | $0.41 | $0.53 | +15% |
| Texas | $0.32 | $0.41 | -10% |
| Florida | $0.36 | $0.46 | 0% |
| New York | $0.41 | $0.53 | +15% |
| Washington | $0.34 | $0.44 | -5% |
| Illinois | $0.38 | $0.48 | +5% |
| Georgia | $0.34 | $0.44 | -5% |
| Colorado | $0.38 | $0.48 | +5% |
High-cost states (HI, CA, NY, MA, CT) run 15–35% above the US average. Low-cost states (TX, OK, WY, ND, SD, UT) typically run ~10% below. Data covers all 51 US states + DC.
Idle fees and other costs
Tesla charges idle fees when you leave your car plugged in after charging completes at a busy station:
- $0.50/minute when the station is ≥50% full
- $1.00/minute when the station is 100% full
- Fee is waived if you move your car within 5 minutes
Time-of-use pricing applies at many stations — peak hours (typically 4–9 PM) can be 20–30% higher than off-peak.
Home vs Supercharger: when does each win?
For daily driving, home charging is almost always cheaper — often by 50% or more. Superchargers make sense for road trips, when you don't have access to home charging, or when time matters more than cost.
A Tesla Model Y driver covering 1,000 miles/month pays about $47/month charging at home vs $100/month on Superchargers — a $636/year difference.

FAQ
How much does it cost to fully charge a Tesla?
$20–$35 on a Supercharger for Model 3 / Model Y; $11–$15 at home. Model S and X run $25–$45 (Supercharger) or $14–$16 (home). Cybertruck is $40–$55 (Supercharger) or $19–$21 (home).
Is Tesla Supercharging free?
No. A small number of older Model S and Model X owners have unlimited free Supercharging tied to their VIN, but it isn't available on new purchases. Everyone else pays per kWh or per minute depending on the state.
Can non-Tesla EVs use Superchargers?
Yes, at Magic Dock and NACS-equipped stations. Non-Tesla pricing is roughly 25–30% higher than the Tesla owner rate (~$0.46/kWh vs $0.36/kWh average).
