Home charging costs depend on your local electricity rate and how much you drive

The cost to charge a Tesla at home ranges from roughly $0.03 to $0.15 per mile, depending on what you pay for electricity in your area. A typical Tesla Model 3 with a 75 kWh battery costs between $9 and $37 to fully charge at home, assuming electricity rates between $0.12 and $0.18 per kilowatt-hour (kWh) — the U.S. average is around $0.14 per kWh, though rates vary significantly by state and utility.

The actual number that matters to you is your own electricity rate. You can find this on your monthly utility bill, usually listed as cents per kWh. Once you know that number, you can calculate your charging cost by multiplying your rate by the battery size of your specific Tesla model.

Key Takeaways

  • Your electricity rate, found on your utility bill, determines charging cost more than anything else — rates range from under $0.10 per kWh in some states to over $0.20 in others.
  • A Tesla Model 3 with a 75 kWh battery costs $9 to $37 to fully charge depending on your local rate, while larger models like the Model Y cost proportionally more.
  • Installing a Level 2 home charger costs $500 to $2,500 including equipment and electrician labor, and you may be able to recover some of that cost through federal or state incentives.
  • Charging overnight during off-peak hours, if your utility offers time-of-use rates, can cut your charging cost by 30 to 50 percent.
  • The cost per mile to charge at home is typically less than the cost of gasoline for a comparable gas vehicle in most U.S. locations.

How to calculate your specific charging cost

Start with your electricity rate in cents per kWh from your utility bill. Then find your Tesla model's battery capacity — the Model 3 Standard Range Plus has 54 kWh, the Model 3 Long Range has 75 kWh, the Model Y Standard Range has 75 kWh, and the Model Y Long Range has 81 kWh. Multiply the battery size by your rate and divide by 100 to get the cost in dollars.

For example: if you pay $0.14 per kWh and own a Model 3 Long Range with a 75 kWh battery, the math is (75 × 0.14) ÷ 100 = $10.50 per full charge. That same charge at $0.18 per kWh would cost $13.50. The difference between a cheap-electricity state like Louisiana and an expensive one like Hawaii can be $20 or more per full charge.

You can also think about it in cost per mile. Divide the full-charge cost by the EPA range for your model. A Model 3 Long Range with 358 miles of range that costs $10.50 to charge works out to about $0.03 per mile. A gas car getting 25 miles per gallon at $3.50 per gallon costs $0.14 per mile, so home charging is typically much cheaper.

Level 2 home charger installation costs

Most Tesla owners install a Level 2 home charger, which charges faster than the standard 120-volt outlet that comes with the car. A Level 2 charger requires 240-volt power, the same circuit type that powers a clothes dryer or electric oven in your home.

The charger hardware itself costs $300 to $800 depending on the brand and features. Tesla's Wall Connector costs around $595. Installation labor typically runs $200 to $1,500 depending on how far the charger is from your electrical panel and whether your panel has available capacity. If your panel needs an upgrade, add $500 to $2,000. Total installed cost is usually $500 to $2,500.

Some utilities and state programs offer rebates or tax credits that cover part of the installation cost. The federal tax credit for home EV charging equipment was up to $500 in recent years, though the rules change annually. Check your utility's website and your state's energy office to see what incentives are currently available in your area.

Time-of-use rates can reduce your charging cost significantly

Many utilities offer time-of-use (TOU) rates, which charge less per kWh during off-peak hours — typically late evening through early morning — and more during peak hours. If you charge your Tesla overnight, you can take advantage of the lower off-peak rate.

The savings vary by utility. Some TOU plans charge 30 to 50 percent less during off-peak hours. If your normal rate is $0.14 per kWh but off-peak is $0.08 per kWh, charging overnight saves you roughly $1.50 to $3 per full charge on a Model 3 Long Range. Over a year of daily charging, that adds up to $550 to $1,100 in savings.

Ask your utility whether they offer TOU rates for residential customers. Some utilities make you request the rate change, while others enroll you automatically. You can also use Tesla's built-in charging scheduler to set the car to charge only during off-peak hours, so you don't accidentally charge during expensive peak times.

Comparing home charging to Supercharging and public networks

Home charging is almost always cheaper than Supercharging or public Level 2 networks. Supercharging costs roughly $0.25 to $0.50 per kWh depending on location and demand, which works out to $19 to $37 for a full charge — more than double the home cost in most places. Public Level 2 chargers typically cost $0.15 to $0.30 per kWh or a flat fee of $2 to $5 per session.

For daily driving, home charging is the most economical option. Supercharging makes sense for long road trips when you need to charge quickly and can't wait for a Level 2 charger. If you don't have a driveway or garage where you can install a charger, public networks become your primary option and the cost per mile rises significantly.

What affects your electricity rate and how to lower it

Your utility sets the base rate per kWh, and it varies by region based on the utility's fuel sources, infrastructure costs, and local regulations. States with cheap hydroelectric power like Washington and Oregon have lower rates. States that rely on expensive imported power or have older infrastructure, like California and Hawaii, have higher rates.

You can't change your utility's rate, but you can reduce your overall electricity bill by charging during off-peak hours if your utility offers TOU rates, by using a smart charger that can shift charging to cheaper times automatically, or by installing solar panels to generate your own power. Solar is a long-term investment with high upfront cost, but it can eventually make charging nearly free.

If you're considering a move or choosing between utilities in your area, electricity cost is worth factoring into the decision. The difference between a $0.10 and $0.18 per kWh rate adds up to $600 to $1,000 per year in charging costs for an average driver.

Frequently Asked Questions

How much does it cost to charge a Tesla Model Y at home?

A Model Y Standard Range with a 75 kWh battery costs $9 to $37 to fully charge depending on your electricity rate. A Model Y Long Range with 81 kWh costs roughly $10 to $40. Multiply your local rate in cents per kWh by the battery size and divide by 100 to get your exact cost.

Can I use a regular outlet to charge my Tesla at home?

Yes, but it's slow. A standard 120-volt outlet charges a Model 3 at about 2 to 3 miles of range per hour. A Level 2 charger on 240 volts charges at 25 to 30 miles per hour, so you can fully charge overnight. Most owners install Level 2 for convenience, though the standard outlet works if you charge infrequently or have a short commute.

Will charging my Tesla increase my electricity bill noticeably?

Yes, but usually less than you'd spend on gas. If you drive 12,000 miles per year in a Model 3 at $0.14 per kWh, charging costs roughly $500 annually. A gas car getting 25 mpg at $3.50 per gallon costs about $1,680 per year, so you save money overall despite the higher electricity bill.

Do I need a permit to install a home charger?

Most jurisdictions require an electrical permit for Level 2 charger installation because it involves 240-volt wiring. Your electrician typically handles the permit process and inspection. Permit costs range from $50 to $300 depending on your location. Skipping the permit can create problems when you sell your home or file an insurance claim.

What's the difference between a Tesla Wall Connector and other Level 2 chargers?

The Tesla Wall Connector is Tesla's branded charger and costs around $595. Other Level 2 chargers from brands like Chargepoint, Eaton, and Siemens cost $300 to $700 and work with any EV, not just Tesla. All Level 2 chargers charge at similar speeds. The main difference is appearance, smart features, and whether you want a charger that works with multiple vehicle brands.
