Charging a Tesla costs money, but the amount depends on where you charge and your local electricity rates

Charging at home on a standard household outlet costs roughly one-third to one-half what gasoline costs per mile, but the exact price shifts with your regional electricity rates and the time of day you charge. Public charging networks charge per kilowatt-hour (kWh), per minute, or a flat fee depending on the network — Tesla's Supercharger network, for instance, charges by the kWh in most regions, while some third-party networks charge by time spent plugged in. If you charge only at home during off-peak hours, your cost per mile can drop further; if you rely on fast-charging networks during peak times, your per-mile cost rises.

The total cost of ownership for a Tesla includes electricity rather than gasoline, but the math is straightforward: multiply your local electricity rate by the kilowatt-hours your car uses. A Model 3 Standard Range Plus uses roughly 24 kWh to travel 200 miles. At the U.S. average electricity rate of $0.14 per kWh (though rates vary widely by state and utility), that 200-mile charge costs about $3.36 at home — far less than the $25 to $35 a gasoline car would need for the same distance.

Key Takeaways

  • Home charging on a standard 120-volt outlet costs the least per mile but charges slowly; a 240-volt home charger costs $500 to $2,500 upfront but reduces per-mile charging costs and charges much faster.
  • Tesla Superchargers charge by the kilowatt-hour and typically cost $0.25 to $0.50 per kWh, making a full charge $19 to $38 — more than home charging but less per mile than gasoline in most U.S. regions.
  • Third-party public networks like Electrify America and EVgo charge by the minute or kilowatt-hour and often cost more than Tesla Superchargers, especially for fast charging sessions.
  • Time-of-use electricity rates at home can cut your charging cost by 30 to 50 percent if you charge during off-peak hours, usually late evening or early morning.
  • Workplace and destination chargers are often free or low-cost, which can eliminate most or all of your daily charging expenses if you have regular access to them.

Home charging costs depend on your electricity rate and outlet type

The cost to charge at home is straightforward your local electricity rate multiplied by the kilowatt-hours your Tesla draws. A Tesla Model 3 Standard Range Plus uses roughly 24 kWh to travel 200 miles. If your electricity costs $0.14 per kWh (the U.S. average as of 2024, though rates vary widely by state and utility), charging that 200 miles costs about $3.36. In states with lower rates like Louisiana or Oklahoma, the cost drops; in states like California or Massachusetts with higher rates, it rises. You can find your exact electricity rate on your utility bill under the per-kWh charge, which is separate from fixed monthly fees.

The outlet you use changes both the speed and the total cost. A standard 120-volt household outlet charges slowly — roughly 2 to 3 miles of range per hour — and costs nothing extra to install. A 240-volt home charger (also called a Level 2 charger) charges 25 to 30 miles of range per hour and requires a licensed electrician to install, typically costing $500 to $2,500 depending on your home's electrical panel and distance from the garage. Once installed, the per-mile charging cost is identical to 120-volt charging; you straightforward pay the electricity rate. The higher upfront cost pays for itself through faster charging and the convenience of starting each day with a full battery.

Time-of-use rates can cut your home charging cost significantly

Many utilities offer time-of-use (TOU) electricity rates that charge less during off-peak hours — typically 9 p.m. to 6 a.m. — and more during peak hours. If your utility offers TOU rates, charging during off-peak hours can reduce your per-kWh cost by 30 to 50 percent. A Tesla owner on a TOU plan paying $0.10 per kWh off-peak versus $0.25 per kWh during peak hours saves roughly $3 per full charge by plugging in after 9 p.m. instead of during the day. Over a year, that difference adds up to $1,000 or more for owners who charge daily.

Not all utilities offer TOU rates, and not all regions allow you to switch to them. Check your utility's website or call their customer service line to ask whether time-of-use rates are available for your account. If they are, compare the off-peak and peak rates to see whether the savings justify shifting your charging schedule. For owners who charge daily at home, the math often favors off-peak charging; for those who charge only occasionally, the difference may be small.

Tesla Supercharger costs vary by location and time of day

Tesla Superchargers charge by the kilowatt-hour in most U.S. locations, with prices typically ranging from $0.25 to $0.50 per kWh depending on the region and local electricity costs. A full charge on a Model 3 (roughly 75 kWh) costs between $19 and $38 at a Supercharger, compared to $3 to $5 at home. However, Superchargers are designed for road trips, not daily charging — a 20-minute charge typically adds 150 to 200 miles of range, which is enough to reach the next Supercharger or your destination.

Some Supercharger locations charge more during peak hours (typically 4 p.m. to 9 p.m.) and less during off-peak times. A few locations in high-demand areas like California or New York charge premium rates year-round. Tesla publishes its Supercharger rates on its website and in the navigation menu of the vehicle, so you can see the exact price before you plug in. If you own a Tesla, you can also set up notifications to charge during cheaper hours, which is useful if you're stopping for a meal or rest break anyway.

Third-party public charging networks charge differently than Superchargers

Networks like Electrify America, EVgo, and Volta operate public chargers that are not owned by Tesla. These networks charge in different ways: some by the minute, some by the kilowatt-hour, and some with a monthly subscription. Electrify America's DC fast chargers, for example, charge roughly $0.43 per kWh in most regions, which is higher than most Tesla Superchargers. EVgo charges by the minute for fast charging, typically $0.28 to $0.35 per minute, which can add up quickly on a long charge session.

Many third-party networks offer membership plans that reduce per-kWh or per-minute costs if you charge frequently. Electrify America's membership plan, for instance, reduces the per-kWh rate by roughly 10 to 15 percent. If you plan to use public chargers regularly, compare the membership cost against your expected usage to see whether it saves money. For occasional road trips, paying per-use is usually cheaper than a membership.

Road trip charging costs less than gasoline but more than home charging

A typical road trip that relies on Superchargers or third-party fast chargers costs roughly $0.04 to $0.06 per mile in charging fees, compared to $0.10 to $0.15 per mile for a gasoline car. A 500-mile road trip in a Tesla might cost $20 to $30 in Supercharger fees; the same trip in a gas car typically costs $50 to $75. However, the time cost matters too — a Supercharger session takes 20 to 30 minutes to add 150 to 200 miles, whereas a gas fill-up takes 5 minutes. If you factor in rest breaks and meal stops, the time difference is often negligible.

The total cost of a road trip also depends on your charging strategy. Charging to 80 percent is faster and cheaper per mile than charging to 100 percent, because charging speed slows dramatically in the final 20 percent. Most road-trippers charge to 80 percent, drive to the next Supercharger, and repeat. This approach minimizes both time and cost compared to fully charging at each stop.

Workplace and destination chargers are often free or low-cost

Many employers, shopping centers, and hotels offer Level 2 chargers that are free or low-cost to use. Workplace chargers are often free to employees and can add 20 to 30 miles of range during an 8-hour workday, which covers most daily driving without any home charging cost. Shopping centers and hotels sometimes charge a small fee (typically $1 to $3 per session) or include charging free with a purchase or stay.

If you have access to free or cheap charging at work or frequently visited locations, your overall charging cost drops significantly. An owner who charges free at work and at home might spend $30 to $50 per month on electricity, compared to $150 to $200 per month for someone who relies on paid public chargers. Check whether your employer, gym, or favorite shopping destination offers chargers before you assume you need to rely on Superchargers or home charging alone.

Frequently Asked Questions

Is charging a Tesla cheaper than filling up a gas car?

Yes, in almost all U.S. regions. Home charging costs roughly one-third to one-half the per-mile cost of gasoline. Even Supercharger charging, which costs more than home charging, typically costs less per mile than gas. The savings are largest for owners who charge at home and smallest for those who rely on paid public chargers.

Do I have to pay to use a Tesla Supercharger?

Yes, with rare exceptions. Most Tesla owners pay per kilowatt-hour at Superchargers. Some older Teslas came with free Supercharging for life, but that benefit is no longer offered on new vehicles. A few Supercharger locations in remote areas are free, but these are uncommon.

What's the difference between a Level 2 charger and a Supercharger?

Level 2 chargers (240-volt home or public chargers) charge slowly — 25 to 30 miles per hour — and cost less per kilowatt-hour. Superchargers are DC fast chargers that add 150 to 200 miles in 20 to 30 minutes but cost more per kilowatt-hour. Level 2 is for daily charging; Superchargers are for road trips.

Can I charge my Tesla for free anywhere?

Some workplaces, shopping centers, and hotels offer free Level 2 charging. A few Supercharger locations in remote areas are free. Otherwise, you pay for charging at home, at public networks, or at Superchargers. Free charging is not may provide and varies by location.

How much does it cost to install a home charger?

A 240-volt Level 2 home charger typically costs $500 to $2,500 to install, depending on your home's electrical panel and the distance from the panel to your garage. Some utilities offer rebates that reduce this cost. A 120-volt outlet requires no installation cost but charges very slowly.
