Home charging costs between $3 and $15 per full charge, depending on your local electricity rate and which Tesla model you own

The cost to charge a Tesla at home is straightforward math: your local electricity rate multiplied by the car's battery capacity. A Tesla Model 3 Standard Range has a 54 kWh usable battery; a Model Y Long Range has 75 kWh. If you pay 15 cents per kilowatt-hour (the U.S. average hovers around 14 to 16 cents), charging a Model 3 from empty costs roughly $8, and a Model Y costs roughly $11. In states with cheaper power—Louisiana, Oklahoma, Washington—the same charge might cost $4 to $6. In Hawaii or Massachusetts, where rates exceed 25 cents per kWh, it can reach $13 to $19.

Your actual cost depends on three variables you can measure: your electricity rate (check your utility bill), your car's battery size (Tesla lists this in your owner's manual and on the window sticker), and how often you charge from completely empty. Most owners charge overnight when the battery is 20 to 80 percent depleted, so you are replacing roughly 40 to 50 kWh, not the full capacity. Time-of-use rates—where electricity costs less during off-peak hours—can cut your charging cost by 30 to 50 percent if you charge between 9 p.m. and 6 a.m.

Key Takeaways

  • Home charging costs $3 to $15 per full charge depending on your electricity rate and which Tesla model you own, and most owners spend $30 to $50 per month on charging.
  • Supercharging on the road costs roughly $0.25 to $0.50 per kWh, or $15 to $30 for a 30-minute charge that adds 200 miles of range.
  • Your actual monthly cost depends on how much you drive, whether you charge at home or use public chargers, and whether your utility offers time-of-use rates.
  • Installing a Level 2 home charger costs $500 to $2,500 including the equipment and electrician labor, and pays for itself in fuel savings within two to four years for most owners.

How to calculate your home charging cost

Find your electricity rate on your utility bill—it is usually listed as cents per kilowatt-hour (kWh) and may vary by time of day. Multiply that rate by your Tesla's usable battery capacity. The usable capacity is slightly less than the total capacity because Tesla reserves a buffer at the top and bottom to protect the battery. A Model 3 Standard Range has 54 kWh usable; a Model 3 Long Range has 75 kWh; a Model Y Standard Range has 60 kWh; a Model Y Long Range has 75 kWh; a Model S or Model X Long Range has 100 kWh.

Example: You live in Texas where electricity costs 12 cents per kWh. You own a Model 3 Long Range with 75 kWh usable capacity. A full charge costs 75 × $0.12 = $9. If you charge four times per week, your monthly cost is roughly $144. If you charge only twice per week, it is roughly $72.

Most owners do not charge from completely empty. If you charge from 20 percent to 80 percent—a common pattern that extends battery life—you are replacing 60 kWh, not 75. That same Model 3 in Texas would cost $7.20 per charge, or $115 per month at four charges per week.

Supercharging costs on road trips

Tesla's Supercharger network charges by the kilowatt-hour, not by time, though pricing varies by location and time of day. As of early 2024, Supercharging costs roughly $0.25 to $0.50 per kWh in most U.S. locations, with higher rates in urban areas and lower rates in rural regions. A 30-minute Supercharge that adds 200 miles of range typically costs $15 to $30.

Supercharging is most expensive per mile on short trips because the charging speed slows as the battery approaches full capacity. Charging from 10 to 80 percent takes roughly 25 to 30 minutes and costs less per kWh than charging from 80 to 100 percent, which can take another 15 to 20 minutes at a much slower rate. For road trips, most owners charge to 80 percent, drive until the battery reaches 10 to 20 percent, then charge to 80 percent again—a pattern that minimizes both time and cost.

Third-party charging networks like Electrify America and EVgo charge $0.30 to $0.60 per kWh and are often more expensive than Tesla Superchargers. Some networks charge by the minute instead of by the kilowatt-hour, which can be unpredictable if the charger is slow or busy.

Monthly charging costs for typical driving patterns

A Tesla owner who drives 1,000 miles per month—roughly 23 miles per day—and charges entirely at home in a state with average electricity rates (15 cents per kWh) will spend $35 to $50 per month on charging. That same owner in a low-cost state like Louisiana might spend $20 to $30; in an expensive state like Hawaii, $60 to $80.

An owner who drives 2,000 miles per month and uses a mix of home charging and occasional Supercharging might spend $70 to $120 per month. Someone who takes frequent road trips and relies heavily on Supercharging could spend $150 to $250 per month, though this is still typically cheaper than gasoline for the same mileage.

To compare: a gasoline car averaging 25 miles per gallon costs roughly $0.12 to $0.15 per mile in fuel alone (at $3 to $3.50 per gallon). A Tesla costs roughly $0.03 to $0.06 per mile in electricity, even accounting for Supercharging on road trips.

Home charger installation and equipment costs

A Level 2 home charger—the standard option for most owners—costs $300 to $1,200 for the equipment itself. Installation labor ranges from $200 to $1,500 depending on how far your electrical panel is from the garage, whether the panel has spare capacity, and local electrician rates. A complete installation typically costs $500 to $2,500.

Some utilities and state programs offer rebates for home charger installation, ranging from $100 to $1,000. The federal tax credit does not cover charger installation as of 2024, though some states include it in their own incentive programs. Check your utility's website or contact your state's energy office to learn what rebates are available in your area.

A Level 2 charger adds 25 to 30 miles of range per hour of charging, so a full overnight charge (8 to 10 hours) is realistic for most owners. A Level 1 charger—a standard 120-volt outlet—adds only 2 to 3 miles per hour and is impractical for daily use unless you drive very short distances.

Factors that change your charging cost

Time-of-use rates: Many utilities charge less for electricity during off-peak hours (typically 9 p.m. to 6 a.m. or 10 p.m. to 7 a.m.). Charging during these hours can reduce your cost by 30 to 50 percent. Tesla's app lets you schedule charging to start at a specific time, so you can take advantage of lower rates automatically.

Battery degradation: Tesla batteries lose capacity very slowly—roughly 5 to 10 percent over 200,000 miles. This means your charging cost per mile increases slightly over time, but the effect is minimal for most owners over the first five to ten years.

Cold weather: Charging a Tesla in freezing temperatures uses more energy because the battery management system heats the battery during charging. This can increase your cost by 10 to 20 percent in winter, though the effect is temporary and only applies to that single charge.

Charging speed: Charging more slowly (using a Level 1 or Level 2 charger) is slightly more efficient than Supercharging, which generates heat and wastes some energy. The difference is small—roughly 5 to 10 percent—but it adds up if you Supercharge frequently.

Comparing Tesla charging to gasoline and other electric vehicles

A Tesla Model 3 Long Range costs roughly $0.04 to $0.05 per mile in electricity (at 15 cents per kWh and 25 miles per kWh efficiency). A gasoline car averaging 30 miles per gallon costs roughly $0.10 to $0.12 per mile in fuel (at $3 to $3.50 per gallon). Over 100,000 miles, the Tesla saves $6,000 to $8,000 in fuel costs alone.

Other electric vehicles have similar per-mile costs. A Chevrolet Bolt EV is slightly more efficient than a Tesla Model 3 (roughly 26 miles per kWh versus 25), so the cost difference is negligible. A Hyundai Ioniq 6 is more efficient (roughly 28 miles per kWh) but costs more upfront. The real difference is in Supercharger availability—Tesla's network is larger and faster than any competitor's, which matters most if you take frequent road trips.

Frequently Asked Questions

How much does it cost to charge a Tesla per mile?

At average U.S. electricity rates (15 cents per kWh) and typical Tesla efficiency (25 miles per kWh), charging costs roughly $0.06 per mile at home. Supercharging on the road costs roughly $0.10 to $0.15 per mile. For comparison, a gasoline car costs $0.10 to $0.15 per mile in fuel alone.

Is it cheaper to charge at home or use Superchargers?

Home charging is always cheaper per kilowatt-hour. Supercharging costs roughly four to eight times more per kWh than home charging. For daily driving, charge at home. Use Superchargers only for road trips where home charging is not an option.

Do I need to pay for a Tesla Supercharger membership?

No. Tesla Supercharging is pay-as-you-go—you pay only for the electricity you use. Some older Teslas came with free Supercharging for life, but new cars do not. You can also use third-party networks like Electrify America without a membership, though they are usually more expensive.

How much does it cost to install a home charger?

Equipment costs $300 to $1,200; installation labor costs $200 to $1,500. A complete installation typically runs $500 to $2,500. Some utilities and states offer rebates of $100 to $1,000. The installation pays for itself in fuel savings within two to four years for most owners.

Does charging a Tesla cost more in winter?

Yes, slightly. Cold weather charging uses 10 to 20 percent more energy because the battery management system heats the battery. This effect is temporary and applies only to that single charge. Over a full year, the winter increase is usually $10 to $30 for most owners.
