Home charging costs between $3 and $15 per full charge, depending on your local electricity rate and which Tesla model you own
A Tesla Model 3 with a 50-kilowatt-hour battery charged on average U.S. residential power costs roughly $6 to $8 per full charge. A Model S with a larger 75-kilowatt-hour battery costs more — usually $9 to $12. These numbers assume you charge during off-peak hours; charging during peak demand hours can push costs higher. The real variable is your local electricity rate, measured in cents per kilowatt-hour. If you pay 12 cents per kilowatt-hour (close to the U.S. average), a Model 3 costs about $6 to charge fully. If you live in a state like Louisiana where rates run around 9 cents per kilowatt-hour, the same charge costs $4.50. In Hawaii or Massachusetts, where rates exceed 20 cents per kilowatt-hour, a full charge can exceed $10. You can find your rate on your electricity bill or your utility's website.
Home charging also requires an upfront investment in equipment. A standard 120-volt outlet (the one in your garage) charges very slowly — roughly 3 miles of range per hour. Most Tesla owners install a Wall Connector, a 240-volt charger that costs $500 to $750 for the unit plus $500 to $2,000 for installation, depending on your home's electrical setup. Some utilities offer rebates that reduce this cost. Once installed, a Wall Connector adds roughly $1 to $2 per month to your electricity bill in standby power. After the initial investment, home charging becomes your lowest-cost option for daily driving.

How Supercharging pricing works and what you actually pay
Tesla's Supercharger network charges by the kilowatt-hour in most U.S. locations, though some older stations still charge by the minute. Per-kilowatt-hour pricing typically ranges from $0.25 to $0.50 depending on location and demand. A Model 3 charging from 10% to 80% battery (the most efficient range for fast charging) uses roughly 40 kilowatt-hours and costs $10 to $20. Charging from 80% to 100% costs significantly more per kilowatt-hour because the charging speed slows dramatically to protect the battery, meaning you pay more for each additional mile of range at the end of a charge cycle.
Supercharging from empty to full is rarely the most cost-effective choice. Charging to 80% takes 25 to 35 minutes and costs less per mile than charging to 100%, which can take an additional 20 to 30 minutes while costing 50% more. Most long-distance Tesla drivers charge to 80%, drive to the next Supercharger, and repeat. This pattern keeps per-mile costs lower than pushing each charge to completion. Supercharger pricing also varies by time and location — urban Superchargers and those in high-demand areas charge more than rural ones. Some stations implement idle fees, currently $0.50 per minute after your car finishes charging, to prevent drivers from leaving vehicles parked at busy locations.
Public charging networks outside the Supercharger network
EVgo, Electrify America, and Volta operate independent fast-charging networks that compete with Tesla's Supercharger system. Pricing structures differ across networks. EVgo charges roughly $0.26 to $0.43 per kilowatt-hour depending on the charger type and location. Electrify America charges $0.43 to $0.50 per kilowatt-hour at DC fast chargers. Volta operates free ad-supported chargers at retail locations, though these charge more slowly than dedicated fast-charging stations. Charging speed at public networks varies widely — Level 2 chargers found at parking lots, shopping centers, and workplaces add 25 to 30 miles of range per hour and cost $1 to $3 per hour, while DC fast chargers add 150 to 200 miles of range per hour and cost $10 to $30 per 20-minute session.
Membership plans can reduce per-kilowatt-hour rates at these networks. EVgo's membership plan costs $9.99 per month and lowers the per-kilowatt-hour rate to roughly $0.19 to $0.29. Electrify America offers a similar membership structure. For drivers who use public chargers frequently, these memberships pay for themselves within a few months. Occasional users typically pay less by charging per session without a membership. The choice between networks often comes down to location and availability rather than price, since most drivers use whatever charger is nearest when they need it.
Workplace and destination charging options
Many employers offer free Level 2 charging to employees, which can eliminate public charging costs entirely for commuters. Workplace chargers typically add 25 to 30 miles of range during an 8-hour workday, enough to cover most daily commutes. If your employer offers this benefit, the cost to you is zero, though the employer pays for the equipment and electricity. Destination chargers at hotels, restaurants, and retail locations also charge for free in most cases — Tesla's app shows the location of over 50,000 destination chargers worldwide. These chargers are typically Level 2 and charge slowly, but they're useful for charging while you shop or dine.
Some premium hotels and resorts charge a fee ($2 to $5 per session) to use their chargers, though this is less common. Workplace and destination charging shifts the cost calculation significantly — a driver who charges at work and home may never use a paid public charger. For these drivers, the only charging cost is home electricity, making the per-mile cost of ownership substantially lower than drivers who rely on public fast-charging networks. The Tesla app shows which chargers are free and which charge a fee before you arrive, so you can plan accordingly.
Comparing home charging to gas vehicle fuel costs
A Tesla Model 3 travels roughly 3.5 to 4 miles per kilowatt-hour when charged at home. At an average U.S. electricity rate of 14 cents per kilowatt-hour, this works out to roughly $0.035 to $0.04 per mile. A comparable gasoline sedan achieving 30 miles per gallon costs roughly $0.10 to $0.12 per mile at current gas prices. Home charging costs roughly one-third as much per mile as gasoline. Public fast-charging narrows this advantage — Supercharging a Model 3 at $0.35 per kilowatt-hour costs roughly $0.09 to $0.10 per mile, nearly matching gasoline costs.
However, most Tesla owners charge primarily at home and use Superchargers only for long trips, so their average per-mile cost remains well below gasoline. A driver who charges 80% of miles at home and 20% on Superchargers pays roughly $0.045 to $0.055 per mile. These calculations exclude maintenance costs, where electric vehicles have a substantial advantage. Teslas require no oil changes, spark plug replacements, or transmission fluid service. Brake wear is minimal due to regenerative braking. Over the vehicle's lifetime, maintenance costs for a Tesla are roughly 40% lower than a comparable gasoline vehicle, which further widens the cost advantage.
Time-of-use rates and how to cut your charging costs
Many utilities offer time-of-use (TOU) electricity plans that charge lower rates during off-peak hours, typically 9 p.m. to 6 a.m. On a TOU plan, off-peak rates might be 8 cents per kilowatt-hour while peak rates reach 25 cents or higher. Charging your Tesla during off-peak hours on a TOU plan can cut your charging cost by 30% to 50% compared to charging during peak hours. Tesla's mobile app and in-vehicle controls allow you to schedule charging to begin at a specific time, making it straightforward to charge during off-peak hours automatically — you set the desired charge level and the time you want charging to complete, and the car handles the rest.
Not all utilities offer TOU plans, and some charge higher rates for TOU than standard plans. Before switching, compare your current bill to the utility's TOU rate structure. Many utilities provide online calculators that estimate your savings based on your usage pattern. If you charge primarily at night and your utility offers TOU rates, switching can save $20 to $40 per month. This scheduling feature requires a Wall Connector or other smart charger that can receive scheduling commands, so it's most practical for owners who have already installed home charging equipment.
Charging costs for different Tesla models
| Model | Battery Size | Home Charge Cost (at $0.14/kWh) | Supercharge Cost (10%-80%) |
|---|---|---|---|
| Model 3 Standard Range | 50 kWh | $7 | $10–$15 |
| Model 3 Long Range | 75 kWh | $10.50 | $15–$20 |
| Model Y Standard Range | 60 kWh | $8.40 | $12–$18 |
| Model Y Long Range | 75 kWh | $10.50 | $15–$22 |
| Model S Long Range | 100 kWh | $14 | $20–$28 |
Larger Tesla models with bigger batteries cost more to charge fully but often cost less per mile because they travel farther on each charge. A Model S with a 100-kilowatt-hour battery costs roughly $14 to charge at home but travels 300+ miles on that charge, working out to roughly $0.047 per mile. A Model 3 with a 50-kilowatt-hour battery costs $7 to charge but travels 200 miles, also roughly $0.035 per mile. The per-mile cost is similar despite the different absolute costs, so choosing a larger model doesn't necessarily increase your per-mile charging expense.
The table above uses a standard electricity rate of $0.14 per kilowatt-hour, which is close to the U.S. average but varies by region. Your actual costs will be higher or lower depending on your local rate. To calculate your specific charging cost, multiply your electricity rate by the battery size and divide by the miles of range the battery provides. This gives you the true per-mile cost for your location and driving pattern.
Frequently Asked Questions
Does charging a Tesla overnight cost more than charging during the day?
Not necessarily. Standard electricity rates are the same 24 hours a day on most plans. However, if your utility offers time-of-use rates, charging at night typically costs less because off-peak rates explore. Check your electricity bill or utility website to see if you're on a TOU plan.
Can I charge my Tesla on a regular 120-volt outlet?
Yes, but it's very slow. A standard outlet adds roughly 3 miles of range per hour, so charging from empty to full takes 40+ hours. Most owners install a 240-volt Wall Connector for practical daily charging, though a standard outlet works for occasional top-ups or if you have time to charge overnight.
What's the difference between Supercharging and Level 2 charging?
Superchargers are DC fast chargers that add 150 to 200 miles of range in 20 to 30 minutes and cost $10 to $30 per session. Level 2 chargers add 25 to 30 miles per hour and cost $1 to $3 per hour or are free at workplaces and destinations. Level 2 is for daily charging; Superchargers are for long trips.
Do I have to pay for charging at Tesla destination chargers?
Most destination chargers at hotels, restaurants, and retail locations are free. Some premium hotels charge $2 to $5 per session. The Tesla app shows which chargers are free and which charge a fee before you arrive.
How much does it cost to install a home charger?
A Wall Connector costs $500 to $750 for the unit. Installation costs $500 to $2,000 depending on your home's electrical panel and how far the charger is from it. Some utilities offer rebates of $100 to $500 that reduce the total cost. After installation, the charger adds roughly $1 to $2 per month to your electricity bill.
