Charging costs depend on where you charge and what electricity rates you pay
The cost to charge a Tesla varies widely depending on whether you charge at home, at a public Level 2 charger, or at a Tesla Supercharger. Home charging is almost always cheapest because you use your household electricity rate. Public chargers and Superchargers charge per kilowatt-hour (kWh) or per minute, and those rates change by location, time of day, and network operator. There is no single answer—a full charge might cost $8 at home or $25 at a Supercharger in a high-cost area.
Understanding the difference between these three charging methods helps you plan your budget and decide where to charge based on your trip and your local electricity costs.
Key Takeaways
- Home charging on a standard household circuit costs roughly $3 to $8 per full charge for most Tesla models, depending on your local electricity rate.
- Public Level 2 chargers typically cost $0.25 to $0.50 per kWh, which translates to $10 to $20 for a full charge, though some networks charge a session fee instead.
- Tesla Superchargers charge by the minute rather than by kWh, with rates ranging from $0.25 to $0.50 per minute depending on location and whether your car is actively charging or parked.
- Charging speed affects total cost: a slower charger takes longer but may charge less per kWh, while a Supercharger is faster but costs more per minute.
- Time-of-use electricity rates at home can cut your charging cost in half if you charge during off-peak hours, usually late evening or early morning.
Home charging: the cheapest option for daily use
Charging a Tesla at home costs the least because you pay your household electricity rate. If your local rate is $0.12 per kWh, charging a Model 3 (which uses about 25 kWh for a full charge) costs roughly $3. If your rate is $0.20 per kWh, the same charge costs $5. Rates vary by region and utility company—California and Hawaii have higher rates (often $0.25 to $0.35 per kWh), while other states average $0.12 to $0.16 per kWh.
Most home charging happens on a standard 120-volt outlet (Level 1), which adds 2 to 3 miles of range per hour. A full charge overnight takes 24 to 48 hours. If you install a 240-volt home charger (Level 2), you add 25 to 30 miles per hour, so a full charge takes 8 to 10 hours. The charger itself costs $500 to $2,500 installed, but the electricity cost per charge remains the same—only the speed changes.
Many utilities offer time-of-use rates that charge less during off-peak hours (usually 9 p.m. to 6 a.m.). If you charge during those hours, your cost can drop by 30 to 50 percent. Check your utility's website or call to see whether time-of-use rates are available in your area and whether they explore to EV charging.
Public Level 2 chargers: moderate cost for longer stops
Public Level 2 chargers are found at shopping centers, parking garages, workplaces, and apartment buildings. They charge at 240 volts and add 25 to 30 miles of range per hour. Most networks charge between $0.25 and $0.50 per kWh, which means a full charge costs $10 to $20 for a Model 3. Some networks charge a flat session fee ($2 to $5) plus a per-minute rate, while others charge only by the kWh.
Common public charging networks include ChargePoint, Electrify America, Evgo, and Tesla's own network of non-Supercharger Level 2 stations. Rates and pricing models differ by network and location. You can check rates in your area through the Tesla navigation system, the Tesla app, or third-party apps like PlugShare.
Public Level 2 chargers make sense for charging while you shop, work, or park for several hours. Because they charge slowly, you pay less per minute than a Supercharger, but you also need time to spare. If you are in a hurry, a Supercharger is faster—but it costs more.
Tesla Superchargers: fastest but most expensive per minute
Tesla Superchargers are high-speed DC chargers found along highways and in urban areas. They add 175 to 200 miles of range in 15 minutes and up to 250 miles in 30 minutes, depending on the model and battery size. Superchargers charge by the minute, not by kWh. Rates vary by location but typically range from $0.25 to $0.50 per minute. At $0.30 per minute, a 30-minute charge costs $9, but a full charge from empty (which takes 45 to 60 minutes) costs $13 to $18.
Supercharger rates are higher in urban areas and lower in rural areas. Rates also change based on local electricity costs and demand. Tesla adjusts pricing dynamically—charging costs more during peak times and less during off-peak times. You can see the current rate at any Supercharger in the Tesla navigation system before you plug in.
Most Teslas do not need a full charge at a Supercharger. The charging curve slows significantly after 80 percent capacity, so charging from 10 to 80 percent (which takes 20 to 25 minutes) is usually the most cost-effective use of a Supercharger. Charging beyond 80 percent takes much longer and costs more per mile of range added.
Comparing total cost across charging methods
The cheapest way to charge a Tesla is at home during off-peak hours on a time-of-use rate plan. A full charge might cost $2 to $4. Home charging during standard rates costs $3 to $8. Public Level 2 chargers cost $10 to $20 per full charge. Superchargers cost $13 to $25 per full charge, depending on location and how much you charge.
For daily commuting, home charging is almost always the best choice financially. For road trips, Superchargers are necessary but you typically charge only to 80 percent, so the cost per mile is lower than it appears. Public Level 2 chargers are useful when you have time to spare and want to avoid Supercharger costs.
The table below shows approximate costs for a Model 3 (which uses about 25 kWh for a full charge) under different scenarios:
| Charging Method | Speed | Cost per Full Charge | Best For |
|---|---|---|---|
| Home (120V) | 2–3 miles/hour | $3–$8 | Overnight charging |
| Home (240V) | 25–30 miles/hour | $3–$8 | Daily use |
| Public Level 2 | 25–30 miles/hour | $10–$20 | Shopping, work, parking |
| Supercharger (10–80%) | 175–200 miles/15 min | $9–$15 | Road trips |
Factors that change your charging cost
Your local electricity rate is the biggest factor in home charging cost. Rates vary by state, utility company, and time of day. California, Hawaii, Massachusetts, and New York have the highest rates, often $0.25 to $0.35 per kWh. Texas, Louisiana, Oklahoma, and Wyoming have the lowest, often $0.10 to $0.14 per kWh. Check your utility bill or your utility's website to find your exact rate.
Battery size also affects cost. A Model 3 Standard Range uses about 25 kWh for a full charge. A Model Y Long Range uses about 35 kWh. A Model S or Model X uses 40 to 50 kWh. Larger batteries cost more to charge, but they also travel farther per charge, so the cost per mile is similar across models.
Charging speed and efficiency matter too. Charging at very cold temperatures reduces efficiency and adds 10 to 20 percent to your energy use. Charging on a 120-volt outlet is less efficient than 240-volt charging, so you may use slightly more kWh to reach the same charge level. These differences are small but add up over time.
Supercharger rates change by location and time of day. Urban Superchargers cost more than rural ones. Charging during peak hours (typically 4 p.m. to 9 p.m.) costs more than charging at 2 a.m. Some Superchargers also charge an idle fee if you leave your car plugged in after charging is complete, typically $0.50 per minute after a 5-minute grace period.
Membership plans and subscription options
Tesla does not charge a subscription fee for Supercharger access. You pay per use based on the rate at that location. However, some public charging networks offer membership plans that reduce per-kWh rates or waive session fees. ChargePoint, Electrify America, and Evgo all have membership options that may save money if you use public chargers frequently.
Some employers and apartment buildings offer free or discounted charging to residents or employees. If you have access to free workplace charging, that eliminates the cost of charging during the workday. Some apartment buildings include charging in rent or offer it at a reduced rate. Check with your employer or landlord to see what is available.
Tesla also offers a Supercharging credit program for certain used vehicle purchases, but this is not a subscription—it is a one-time credit applied to your account. New Tesla purchases do not include free Supercharging, though Tesla occasionally runs promotions offering limited free Supercharging to new buyers.
Frequently Asked Questions
How much does it cost to charge a Tesla compared to filling a gas car?
Home charging a Tesla costs roughly one-third to one-half the cost of filling a comparable gas car. A Model 3 charged at home for $5 travels about 250 miles. A gas car getting 25 mpg would need 10 gallons to travel 250 miles, costing $30 to $40 depending on gas prices. Supercharging is more expensive per mile but still cheaper than gas for most road trips.
Do I pay more to charge a Tesla during peak hours?
At home, yes—if your utility offers time-of-use rates. Public chargers and Superchargers do not always charge more during peak hours, but Tesla Superchargers do adjust pricing based on demand. Check the Tesla app to see the current rate before you plug in. Charging at night or early morning is almost always cheaper.
Can I charge a Tesla for free anywhere?
Some workplaces, apartment buildings, shopping centers, and hotels offer free charging to customers or residents. Tesla does not offer free Supercharging as a standard benefit, though promotional credits are occasionally available. Check your workplace and local chargers through the Tesla app or PlugShare to see what is free in your area.
Is it cheaper to charge to 80 percent or 100 percent?
Charging to 80 percent is more cost-effective per mile because the charging curve slows significantly after 80 percent. The last 20 percent takes much longer and costs more per kWh of energy added. For daily use, charging to 80 percent is fine. For road trips, charge to 80 percent at Superchargers, then charge to 100 percent at home if you need it.
What if my electricity rate is very high in my area?
If your rate is $0.30 per kWh or higher, home charging still costs less than public chargers or Superchargers. Ask your utility whether time-of-use rates are available—they can cut your charging cost significantly. You can also consider installing solar panels, though that is a long-term investment. For now, charging during off-peak hours is the fastest way to reduce cost.
