The real cost depends on your local electricity rate and where you charge

Charging a Tesla costs between $0.03 and $0.14 per mile, depending on whether you charge at home or use a public network, and what your utility company charges for electricity. Most owners charge at home overnight, where the cost is lowest. Public charging networks charge by the kilowatt-hour (kWh) or by the minute, and prices vary widely by location and network.

The total cost to fully charge a Tesla from empty to full ranges from about $8 to $25 at home, or $15 to $35 at a public fast-charging station. A full charge typically adds 200 to 350 miles of range, depending on the model. For comparison, a gas car getting 25 miles per gallon would spend roughly $40 to $60 for the same distance.

Key Takeaways

  • Home charging costs $0.03 to $0.08 per mile in most U.S. locations, based on your local electricity rate and the efficiency of your Tesla model.
  • Public fast-charging networks (like Supercharger) cost $0.20 to $0.35 per mile and are meant for road trips, not daily charging.
  • Installing a Level 2 home charger costs $500 to $2,500 upfront but pays for itself within a few years through lower per-mile costs.
  • Charging speed and cost both depend on the charger type: Level 1 (standard outlet) is free but slow, Level 2 (240V) is moderate cost and speed, and DC fast-charging is expensive but quick.
  • Time-of-use electricity rates from your utility can cut your charging cost by 30 to 50 percent if you charge during off-peak hours.

Home charging: the cheapest option for daily use

Most Tesla owners charge at home using a Level 2 charger connected to a 240-volt outlet, the same type used for electric dryers or ovens. The cost per mile is lowest here because you are using your home electricity rate, which typically ranges from $0.10 to $0.18 per kWh across the United States. A Tesla Model 3 or Model Y uses roughly 0.20 to 0.25 kWh per mile, so charging at home costs about $0.02 to $0.05 per mile.

If you use a standard 120-volt outlet (Level 1), charging is free in terms of electricity cost, but it adds only 2 to 3 miles of range per hour. A full charge takes 24 to 48 hours, making this option practical only if you rarely drive or have weeks between trips.

Installing a Level 2 home charger requires an electrician to run a 240-volt circuit to your garage or driveway. The charger itself costs $400 to $1,200, and installation runs $300 to $1,500 depending on how far the outlet needs to be from your electrical panel. Some utilities offer rebates of $500 to $1,000 for Level 2 installation, which can offset a significant portion of the cost.

Time-of-use rates can cut your charging cost in half

Many utilities offer time-of-use (TOU) electricity rates that charge less during off-peak hours, typically late evening through early morning. If your utility offers this plan, charging between 9 p.m. and 6 a.m. might cost $0.08 to $0.12 per kWh instead of $0.15 to $0.20 during peak hours. Switching to a TOU plan and charging only during off-peak hours can reduce your per-mile cost by 30 to 50 percent.

Check your utility's website or call their customer service line to see whether TOU rates are available in your area. Some utilities automatically enroll new EV owners; others require you to request the plan. The savings add up quickly: if you drive 12,000 miles per year and save $0.02 per mile by shifting to off-peak charging, you save roughly $240 annually.

Public fast-charging networks: expensive but necessary for road trips

Tesla's Supercharger network and third-party networks like Electrify America, EVgo, and Chargepoint charge by the kilowatt-hour or by the minute. Supercharger pricing varies by location but typically ranges from $0.25 to $0.50 per kWh. A full charge on a Model 3 (75 kWh battery) costs $19 to $38 at a Supercharger, or roughly $0.10 to $0.20 per mile. Third-party networks often charge $0.30 to $0.45 per kWh, making them slightly more expensive.

Charging speed at public fast-chargers is much quicker than home charging. A Supercharger adds 175 miles of range in 15 minutes and 200+ miles in 25 minutes. However, charging slows significantly after 80 percent capacity to protect battery health, so a full charge takes 30 to 45 minutes. For this reason, most road-trippers charge to 80 percent and move on.

Public charging networks are not designed for daily use. If you charged at a Supercharger every day, your per-mile cost would be three to five times higher than home charging. These networks exist for road trips and situations where home charging is unavailable.

Workplace and destination charging: often free or low-cost

Many employers, shopping centers, hotels, and apartment complexes offer Level 2 chargers to employees or guests, often at no cost or for a small fee. Workplace charging is particularly valuable because you charge during the day while parked, adding range without taking time out of your schedule. If your workplace offers free charging and you drive 40 miles round-trip daily, you could eliminate most of your charging cost.

Destination chargers at hotels, restaurants, and retail locations typically charge $0.20 to $0.30 per kWh, less than fast-charging networks but more than home rates. These chargers are meant for customers spending an hour or more at the location, not for quick top-ups.

Comparing total cost to gas vehicles

A Tesla Model 3 charging at home costs roughly $0.03 to $0.05 per mile. A gas car averaging 25 miles per gallon costs roughly $0.12 to $0.16 per mile at current gas prices. Over 100,000 miles, the difference is substantial: a Tesla owner might spend $3,000 to $5,000 on electricity, while a gas car owner spends $12,000 to $16,000 on fuel.

The upfront cost of a Level 2 home charger ($800 to $2,500 installed) typically pays for itself within two to four years through fuel savings, depending on how much you drive and your local electricity rates. After that, the savings accumulate year after year.

Factors that affect your actual charging cost

Your local electricity rate is the single biggest factor. Rates vary by state and utility: Louisiana averages $0.09 per kWh, while Hawaii averages $0.28 per kWh. Check your utility bill to find your rate, or search your utility's website for "residential electricity rate."

Your Tesla model also matters. A Model 3 or Model Y is more efficient (0.20 to 0.25 kWh per mile) than a Model S or Model X (0.25 to 0.30 kWh per mile). Driving habits, weather, and highway versus city driving all affect efficiency by 10 to 20 percent.

Finally, the charger type determines both speed and cost. Level 1 (120V) is free but slow. Level 2 (240V) costs $0.02 to $0.08 per mile at home. DC fast-charging costs $0.10 to $0.20 per mile and is only economical for occasional road trips.

Frequently Asked Questions

Is charging a Tesla cheaper than gas?

Yes, significantly. Home charging costs roughly one-third to one-half what gas costs per mile. Even public fast-charging is usually cheaper than gas. The savings grow larger the more you drive and the lower your local electricity rate.

Can I charge a Tesla with a regular outlet?

Yes, using a standard 120-volt outlet (Level 1). It adds only 2 to 3 miles of range per hour, so a full charge takes 24 to 48 hours. This works only if you rarely drive or have long periods between trips. Most owners install a 240-volt Level 2 charger for practical daily use.

How much does it cost to install a home charger?

A Level 2 charger costs $400 to $1,200 for the equipment, plus $300 to $1,500 for installation by a licensed electrician. Total cost is typically $800 to $2,500. Some utilities offer rebates of $500 to $1,000, reducing your net cost. The investment usually pays for itself within two to four years through fuel savings.

What's the difference between Supercharger and other public networks?

Tesla's Supercharger network is exclusive to Tesla vehicles and typically charges $0.25 to $0.50 per kWh. Third-party networks like Electrify America and EVgo charge $0.30 to $0.45 per kWh and are available to all EV brands. Superchargers are generally faster and more reliable, but both are expensive compared to home charging.

Should I charge to 100 percent every time?

No. Charging to 80 percent is faster and better for long-term battery health. For daily use, most owners charge to 80 to 90 percent. Charging to 100 percent is useful only before a long road trip. Public fast-chargers automatically slow down after 80 percent, so charging beyond that point takes significantly longer for minimal range gain.
