The cost to charge a Tesla depends on your local electricity rate, which charger you use, and how far you drive
If you charge at home using a standard outlet, you'll pay whatever your utility company charges per kilowatt-hour (kWh). Most U.S. households pay between 12 and 20 cents per kWh, though this varies significantly by region and time of day. A Tesla Model 3, the most common model, uses about 25 kWh to go 100 miles, so a full charge at home might cost $3 to $5 depending on your local rate.
If you use a public charging network like Tesla Supercharger, Electrify America, or Evgo, the cost is usually higher — typically 25 to 50 cents per kWh, though some networks charge a flat fee per session instead. A full charge at a public fast charger might cost $10 to $25. The exact price depends on which network you use, where you're located, and whether you have a membership plan with that network.
The cheapest way to charge is almost always at home during off-peak hours if your utility offers time-of-use rates. The most expensive is fast charging on a public network during peak times.
Key Takeaways
- Home charging costs $3 to $5 per full charge for most Tesla owners, based on typical U.S. electricity rates of 12 to 20 cents per kWh.
- Public fast-charging networks cost $10 to $25 per full charge, with prices varying by network, location, and time of day.
- Your electricity rate is the main factor that changes your charging cost — check your utility bill to find your rate per kWh.
- Installing a Level 2 home charger (240-volt) costs $500 to $2,500 upfront but saves money over time compared to public charging.
How to find your local electricity rate
Your charging cost starts with knowing what your utility charges per kWh. Look at your most recent electricity bill — it will show your rate, usually listed as cents per kWh. If you see multiple rates (one for peak hours, one for off-peak), write both down.
If you can't find it on your bill, call your utility company's customer service line or visit their website. Many utilities now offer time-of-use plans that charge less during certain hours, usually late evening through early morning. Switching to a time-of-use plan can cut your charging cost by 30 to 50 percent if you charge mostly at night.
Charging at home: outlet types and their costs
A standard 120-volt household outlet (the kind you use for lamps) charges a Tesla very slowly — about 2 to 3 miles of range per hour. This is called Level 1 charging. It's free if you already have the outlet, but it's impractical for daily use unless you drive very short distances.
A 240-volt outlet, called Level 2 charging, adds about 25 to 30 miles of range per hour and is what most home owners install. A Level 2 charger costs $500 to $2,500 to buy and install, depending on your home's electrical setup and your location. Once installed, the cost per charge is straightforward your local electricity rate times the kWh needed — usually $3 to $5 for a full charge.
Tesla also sells the Wall Connector, a 240-volt charger made specifically for Tesla vehicles, which costs around $600 to $750 before installation. Other brands like Grizzl-E or Clipper Creek work with any electric vehicle and may cost less.
Public charging networks and their pricing structures
Tesla Superchargers, which are the fastest public chargers, typically cost 25 to 50 cents per kWh depending on location and demand. During peak times, prices can be higher. A full charge (about 75 kWh for a Model 3) might cost $19 to $38 at a Supercharger. Tesla owners get free Supercharging only if they purchased their vehicle before late 2022, or if they bought a specific package; most new owners pay per use.
Other networks like Electrify America, Evgo, and ChargePoint use different pricing models. Some charge per kWh like Superchargers do. Others charge a flat fee per session (for example, $10 to $15 to charge for 30 minutes). A few require a monthly membership ($10 to $20 per month) that gives you a lower per-kWh rate.
Apps like PlugShare and A Better Route Planner let you see charging networks near you and their current prices before you arrive. Prices change frequently and vary by location, so checking ahead saves money and frustration.
How vehicle size and battery capacity affect charging cost
Larger Tesla models with bigger batteries cost more to charge because they hold more energy. A Model 3 Standard Range has a smaller battery than a Model S Long Range, so it costs less to fill up. The Model 3 uses roughly 25 kWh per 100 miles, while a Model S uses about 26 kWh per 100 miles — very similar efficiency, but the Model S battery is much larger overall.
If you own a Tesla, you can find your vehicle's exact battery size in the owner's manual or by checking your vehicle's settings. Multiply that number by your local electricity rate to estimate your charging cost. For example, a 75 kWh battery charged at 15 cents per kWh costs $11.25 to fully charge.
Comparing home charging to public charging over time
Home charging is almost always cheaper per mile than public charging, even after you account for the cost of installing a charger. If you install a $1,500 Level 2 charger and charge at home for three years at an average cost of $4 per charge, you'll spend roughly $1,500 plus $1,460 in electricity (assuming 365 charges per year). That's about $2,960 total, or roughly $0.04 per mile if you drive 25,000 miles per year.
The same 25,000 miles charged entirely at public fast chargers at $20 per charge would cost roughly $5,000 per year, or $0.20 per mile. The difference adds up quickly. Home charging makes sense if you have a driveway or garage and drive regularly. Public charging is most useful for long road trips or if you live in an apartment without charging access.
Factors that change your charging cost month to month
Your electricity rate may change seasonally. Many utilities charge more during summer months when air conditioning demand is high, and less during winter. Some utilities also raise rates annually. Check your bill every few months to stay aware of changes.
Public charging prices fluctuate based on demand and location. Superchargers in busy areas or during peak hours cost more than those in rural areas or during off-peak times. Some networks use dynamic pricing, meaning the price changes throughout the day. If you charge during less busy times, you'll pay less.
If you have a time-of-use electricity plan at home, charging between 9 p.m. and 6 a.m. might cost half as much as charging during the day. Setting your Tesla to charge during these cheaper hours can significantly reduce your annual electricity costs.
Frequently Asked Questions
Is it cheaper to charge a Tesla than to buy gas?
Yes, for most owners. At current electricity rates and gas prices, charging a Tesla costs roughly one-third to one-half as much per mile as driving a gas car. The exact savings depend on your local electricity rate and gas prices in your area. Over the life of the vehicle, the savings are substantial.
Do I need to pay a membership fee to use public chargers?
It depends on the network. Some networks like Electrify America and Evgo let you pay per use with a credit card and no membership required. Others offer optional memberships that lower your per-kWh rate if you charge frequently. Tesla Supercharging requires payment per use but no membership.
How long does it take to charge a Tesla at home?
With a Level 2 charger (240-volt), a full charge takes 8 to 10 hours for most models. With a standard 120-volt outlet, it takes 24 to 48 hours. Most owners plug in overnight and wake up to a full battery, so charging time is rarely an issue for daily driving.
Can I charge my Tesla for free anywhere?
Some workplaces, shopping centers, and hotels offer free Level 2 charging to customers or employees. A few public chargers are free, though this is becoming less common. Check the PlugShare app to find free chargers in your area, but availability varies widely by location.
What's the difference between Level 1, Level 2, and DC fast charging?
Level 1 uses a standard 120-volt outlet and adds 2 to 3 miles per hour. Level 2 uses 240 volts and adds 25 to 30 miles per hour. DC fast charging (Superchargers and other networks) adds 150 to 200 miles in 20 to 30 minutes. Home charging is almost always Level 2; public networks are usually DC fast charging.
