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: take your local electricity rate per kilowatt-hour (kWh), multiply it by the battery size, and account for charging losses. A Tesla Model 3 Standard Range has a 54 kWh usable battery. If you pay $0.14 per kWh (the U.S. average), a full charge costs about $7.56 before losses. With typical 10 to 15 percent charging losses, you're looking at roughly $8.50 to $9 per full charge. A Model Y Long Range with an 82 kWh battery costs $11.50 to $13 under the same conditions.

Your actual cost depends entirely on what your utility charges. Rates vary by state and region—California averages $0.18 per kWh, while Louisiana averages $0.10. Some utilities offer time-of-use rates that charge less during off-peak hours (often 9 p.m. to 6 a.m.), which can cut your charging cost by 30 to 50 percent if you charge overnight. Check your utility bill or their website to find your rate and whether time-of-use pricing is available in your area.

Key Takeaways

  • Home charging costs $3 to $15 per full charge depending on your electricity rate and which Tesla model you own, making it the cheapest way to charge.
  • Time-of-use rates from your utility can cut charging costs in half if you charge during off-peak hours, typically late evening or early morning.
  • Public fast charging (Supercharging) costs $0.25 to $0.50 per kWh, making a full charge $13 to $40 depending on the network and location.
  • The cost per mile to charge a Tesla is roughly one-third to one-half the cost per mile of gasoline in most U.S. markets.

How to calculate your home charging cost

Find your electricity rate on your utility bill—it's usually listed as cents per kWh. Multiply that rate by the Tesla's usable battery capacity, then add 10 to 15 percent for charging losses. For example: Model 3 Standard Range (54 kWh) × $0.14 per kWh = $7.56, plus losses = $8.50 to $9.

If you don't know your rate, visit your utility's website or call their customer service line. Many utilities publish rates by zip code. Once you have the number, you can estimate your monthly charging cost by dividing your typical monthly miles driven by the Tesla's efficiency (usually 3.5 to 4 miles per kWh for Model 3, 3 to 3.5 for Model Y). A Model 3 driven 1,000 miles per month at 3.7 miles per kWh uses about 270 kWh, costing roughly $38 at $0.14 per kWh.

Supercharging and public network costs

Tesla Supercharging costs $0.25 to $0.50 per kWh depending on location and time of day. Peak pricing (typically 4 p.m. to 9 p.m.) is higher than off-peak. A full charge on a Model 3 at $0.35 per kWh costs about $19. The same charge on a Model Y costs roughly $29. Supercharging is fastest—adding 200 miles in 20 to 30 minutes—but costs three to five times more than home charging.

Other public networks like Electrify America, EVgo, and ChargePoint charge $0.30 to $0.45 per kWh, with some offering monthly memberships that reduce the per-kWh rate by $0.05 to $0.10. Level 2 chargers at shopping centers, workplaces, and parking lots charge $0.15 to $0.30 per kWh and take 6 to 10 hours for a full charge, but are cheaper than Supercharging and often free at workplaces.

Charging at work and public Level 2 chargers

Many employers offer free or subsidized Level 2 charging, which adds 25 to 30 miles of range per hour. If you charge 4 hours at work five days a week, you add roughly 500 to 600 miles per week at no cost—potentially covering most of your driving without touching home charging or Supercharging. Check with your HR or facilities department about availability.

Public Level 2 chargers at shopping centers, parking garages, and municipal lots typically cost $1 to $3 per hour or $0.15 to $0.30 per kWh. Some are free, especially at newer shopping centers trying to attract EV drivers. Apps like PlugShare and A Better Route Planner show which chargers are free and which charge fees.

Cost comparison: Tesla charging versus gasoline

A Tesla Model 3 costs roughly $0.04 to $0.05 per mile to charge at home (at $0.14 per kWh and 3.7 miles per kWh). A gasoline car averaging 30 mpg costs $0.10 to $0.13 per mile at $3 to $4 per gallon. Even using Supercharging at $0.35 per kWh, a Model 3 costs about $0.09 per mile—still cheaper than most gasoline cars. The savings grow if you charge during off-peak hours or have free workplace charging.

Over a year, a driver covering 12,000 miles would spend roughly $480 to $600 charging at home, compared to $1,200 to $1,560 for gasoline. The gap widens in states with lower electricity rates (Louisiana, Oklahoma, Washington) and narrows in states with higher rates (Hawaii, Massachusetts, California), though even in high-rate states, EV charging remains cheaper than gasoline.

Installation costs for home charging equipment

A Level 2 home charger costs $500 to $2,500 installed, depending on whether your home's electrical panel needs upgrades. A basic 240-volt charger (like the Tesla Wall Connector) costs $500 to $750 for the unit, plus $500 to $2,000 for installation if your home already has a 240-volt outlet nearby. If your panel needs a new circuit or capacity upgrade, installation can reach $2,000 to $3,000.

Some states and utilities offer rebates of $500 to $2,000 for Level 2 installation. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or your utility's website for current programs in your area. The federal tax credit for home EV charging equipment was $30 percent of installation costs up to $1,000, though this program's future is uncertain—verify current status before planning your budget.

Charging speed and cost trade-offs

Slower charging is cheaper. Home Level 2 charging at $0.04 to $0.05 per mile takes 8 to 12 hours but costs the least. Public Level 2 at $0.06 to $0.08 per mile takes 6 to 10 hours and costs slightly more. Supercharging at $0.09 to $0.13 per mile takes 20 to 40 minutes but costs three to five times more per kWh. The choice depends on your schedule: if you can charge overnight at home, Supercharging becomes an occasional expense for road trips, not a regular cost.

For daily driving under 200 miles, home charging alone covers most needs. For frequent long-distance travel, Supercharging costs add up quickly. A 500-mile road trip using Supercharging costs $65 to $100 in charging alone, versus $20 to $25 if you could charge at home overnight.

Frequently Asked Questions

Does charging a Tesla overnight cost more than charging during the day?

Not if your utility offers time-of-use rates—most charge less during off-peak hours (typically 9 p.m. to 6 a.m.). Check your utility bill or website to see if this rate is available. If it is, overnight charging can cost 30 to 50 percent less than daytime charging.

Is it cheaper to use a Supercharger or charge at home?

Home charging is cheaper by a large margin. A full charge at home costs $8 to $13 for most Teslas; the same charge at a Supercharger costs $19 to $40. Use Superchargers for road trips, not daily charging.

What if I don't have a garage or driveway for a home charger?

You can use public Level 2 chargers at work, shopping centers, or parking lots, though they cost more than home charging and take longer. Some apartments and condos have shared charging. If neither is available, Supercharging is an option but becomes expensive for daily use.

Do I need a special outlet to charge a Tesla at home?

A standard 120-volt outlet charges very slowly (2 to 3 miles per hour). A 240-volt Level 2 charger is much faster (25 to 30 miles per hour) and requires installation. Most homes have 240-volt service available, but installation costs $500 to $3,000 depending on your electrical setup.

How much does it cost to charge a Tesla on a road trip?

A 500-mile road trip using Supercharging costs roughly $65 to $100 in charging, depending on the Tesla model and Supercharger pricing in the regions you travel. Charging overnight at hotels or stopping at public Level 2 chargers (if time allows) reduces this cost significantly.
