The real cost depends on where you charge and your local electricity rates
Charging a Tesla at home costs between $3 and $15 per full charge on a Level 2 home charger, depending on your regional electricity price and your car's battery size. A Tesla Model 3 with a 75 kWh battery costs roughly $9 to $12 to fully charge at the U.S. average electricity rate of 16 cents per kilowatt-hour. A larger Model S or Model X costs $15 to $20. Public fast charging (DC fast chargers) costs $10 to $30 per session depending on the network, location, and how long you charge.
The math is straightforward: multiply your local electricity rate (in cents per kilowatt-hour) by the battery size you're charging, then divide by 100. If you pay 12 cents per kWh and charge a 75 kWh battery, that's 75 × 12 ÷ 100 = $9. Your actual electricity bill will vary based on the time of day you charge (many utilities charge less at night), whether you have a time-of-use rate plan, and how efficiently your charger transfers power.
Key Takeaways
- Home charging on a Level 2 charger typically costs $0.12 to $0.20 per kilowatt-hour, making a full charge $9 to $15 for most Tesla models.
- DC fast charging networks charge per minute or per kilowatt-hour, ranging from $0.25 to $0.50 per kWh, and cost $10 to $30 per session depending on how much you charge.
- Time-of-use electricity rates can cut your home charging cost by 30 to 50 percent if you charge during off-peak hours, usually late evening or early morning.
- Public charging networks like Tesla Supercharger, Electrify America, and EVgo have different pricing models and coverage, so costs vary by location and provider.
- Installing a home Level 2 charger costs $500 to $2,500 including equipment and electrician labor, but pays for itself within two to four years of regular charging.
Home charging costs and what affects the price
The cost to charge at home depends almost entirely on your local electricity rate. You can find your rate on your utility bill under "cents per kilowatt-hour" or "kWh rate." Most U.S. households pay between 12 and 20 cents per kWh, though rates in Hawaii, California, and the Northeast run higher (25 to 35 cents), and rates in Louisiana and Oklahoma run lower (8 to 10 cents).
A Tesla Model 3 Standard Range Plus has a 54 kWh usable battery; a Model 3 Long Range has 75 kWh; a Model Y Long Range has 75 kWh; and a Model S Long Range has 100 kWh. Charging from 10 percent to 90 percent (the typical safe range) uses about 80 percent of the battery's rated capacity. At 16 cents per kWh, charging a Model 3 Long Range from 10 to 90 percent costs roughly $9.60.
Many utilities offer time-of-use (TOU) rates that charge less during off-peak hours—typically 9 p.m. to 6 a.m. on weekdays. If your off-peak rate is 10 cents per kWh and your peak rate is 25 cents, charging overnight saves you about $3.75 per charge. Over a year of daily charging, that's $1,400 in savings. Ask your utility whether a TOU plan is available for your address; some require a smart meter installation, which is usually free.
Public DC fast charging networks and their pricing
Tesla Superchargers charge by the minute or kilowatt-hour depending on your vehicle and location. Newer Superchargers in urban areas typically charge $0.25 to $0.50 per kWh. A 20-minute charge (adding 200 miles of range to a Model 3) costs $8 to $16. Supercharging is most economical for long trips; charging at home is always cheaper per mile.
Electrify America and EVgo, the two largest non-Tesla networks, charge $0.30 to $0.43 per kWh at DC fast chargers. A 30-minute session adding 150 miles of range costs $12 to $20. Both networks offer membership plans—Electrify America's monthly plan is $4 and gives a small per-kWh discount; EVgo's membership is free but offers no discount. Neither membership is necessary; you can pay per session with a credit card.
Pricing varies significantly by location. Rural chargers are often cheaper than urban ones. Chargers in shopping centers or along highways may have premium pricing. Check the Tesla app, Electrify America app, or PlugShare before you arrive at a charger to see the current price at that specific location.
Level 2 public chargers and workplace charging
Level 2 chargers at workplaces, shopping centers, and apartment buildings charge much slower than DC fast chargers but cost far less—typically $1 to $3 per hour or $0.15 to $0.25 per kWh. A two-hour charge adds 20 to 30 miles of range and costs $2 to $6. Many employers offer free Level 2 charging as an employee benefit, and some municipalities provide free or low-cost public Level 2 chargers in parking lots.
If you have access to free or cheap Level 2 charging at work or home, you may never need to use a DC fast charger except on long road trips. A person who charges at home overnight and tops up at work during the day can drive 300+ miles per week on home electricity alone, costing $20 to $30 per week.
Installation costs for a home Level 2 charger
A Level 2 home charger (also called a Wall Connector or EVSE) costs $500 to $2,500 installed. The charger itself costs $300 to $800; the electrician labor and wiring upgrades cost $200 to $1,700 depending on your home's electrical panel capacity and distance from the garage. If your home already has a 240-volt outlet (like a dryer outlet), installation is simpler and costs $300 to $600. If you need a new 240-volt circuit, expect $800 to $1,500.
Some states and utilities offer rebates for home charger installation. California offers up to $500 through the California Energy Commission; New York offers up to $500 through Con Edison and other utilities; Massachusetts offers up to $1,000. Check your state's energy office website or ask your utility whether a rebate is available. A home charger pays for itself in two to four years if you charge daily, because home charging is so much cheaper than public DC fast charging.
Comparing total cost: home versus public charging
If you charge exclusively at home, a Tesla Model 3 costs roughly $0.03 to $0.05 per mile (at 16 cents per kWh and 4 miles per kWh efficiency). A gasoline car at $3.50 per gallon and 25 mpg costs $0.14 per mile. Over 12,000 miles per year, home charging costs $360 to $600; gasoline costs $1,680. The difference is $1,080 per year.
If you rely on DC fast charging, the cost rises to $0.06 to $0.10 per mile, still cheaper than gasoline but much more expensive than home charging. A person who charges at home 80 percent of the time and uses DC fast chargers 20 percent of the time pays roughly $0.04 per mile, or $480 per year for 12,000 miles.
Factors that change your charging cost
Charger efficiency matters. A Level 2 home charger is typically 85 to 95 percent efficient, meaning 5 to 15 percent of the electricity you pay for is lost as heat. DC fast chargers are 70 to 85 percent efficient. This loss is built into the per-kWh cost you see on the charger's screen, so you do not need to calculate it separately.
Cold weather reduces charging efficiency and battery range. In temperatures below 32°F, a Tesla's battery heats itself before accepting a fast charge, which uses 10 to 20 percent more energy. This means a DC fast charge in winter costs 10 to 20 percent more than the same charge in summer. Home charging is less affected because the car has hours to warm the battery gradually.
Charging speed affects cost at DC fast chargers. Charging from 10 to 80 percent is fastest and cheapest per mile; charging from 80 to 100 percent is much slower and costs more per mile because the charger reduces power to protect the battery. On a road trip, it is usually cheaper to charge to 80 percent and drive to the next charger than to charge to 100 percent.
Frequently Asked Questions
How much does it cost to charge a Tesla compared to filling a gas car?
Home charging costs roughly $0.03 to $0.05 per mile; gasoline costs $0.12 to $0.16 per mile at current prices. Over 12,000 miles per year, home charging costs $360 to $600 while gasoline costs $1,440 to $1,920. DC fast charging costs more per mile but is still cheaper than gasoline for most drivers.
Can I charge my Tesla on a regular 120-volt outlet?
Yes, but it is very slow. A standard 120-volt outlet adds 2 to 3 miles of range per hour, so a full charge takes 40 to 50 hours. This works only if you have days between drives. A 240-volt Level 2 charger adds 25 to 30 miles per hour and is far more practical for daily use.
Do I have to pay for Tesla Supercharging?
Yes. Older Teslas (2017 and earlier) came with unlimited free Supercharging, but all new Teslas charge per use. Pricing varies by location and charger, typically $0.25 to $0.50 per kWh. Home charging is always cheaper unless you have free access to a Level 2 public charger.
What is the cheapest way to charge a Tesla?
Home charging on a time-of-use electricity plan during off-peak hours is the cheapest option, costing $0.08 to $0.12 per kWh. If your utility offers off-peak rates between 9 p.m. and 6 a.m., charging overnight cuts your cost by 30 to 50 percent compared to peak-hour charging.
Does charging speed affect how much I pay?
At DC fast chargers, yes. Charging from 10 to 80 percent is fastest and costs less per mile; charging from 80 to 100 percent is slower and costs more per mile because the charger reduces power. At home on a Level 2 charger, speed does not affect cost—you pay the same per kWh whether you charge in 6 hours or 10 hours.
