Charging a Tesla is free at some locations and costs money at others, depending on where you plug in
Whether you pay to charge a Tesla depends entirely on which charger you use. Tesla owners with access to a home charger pay for electricity at their household rate — typically 12 to 16 cents per kilowatt-hour in most of the US, though this varies by region and time of day. Owners without home charging can use Tesla's Supercharger network, which costs money, or third-party public chargers, which may be free or paid depending on the network and location.
The confusion usually comes from the fact that Tesla has offered free Supercharging as a perk to certain buyers, but that benefit is not universal and has changed over time. Some older Tesla models came with free lifetime Supercharging; newer purchases typically do not. Even if you have free Supercharging, you still pay for home charging if you use it.
Key Takeaways
- Home charging costs whatever your local electricity rate is, usually between $0.03 and $0.06 per mile of range, depending on your region and your car's efficiency.
- Tesla Superchargers cost money for most owners, typically $0.25 to $0.50 per kilowatt-hour, though prices vary by location and time of day.
- Free Supercharging was included with some older Tesla purchases but is not standard on new vehicles.
- Many public charging networks run by other companies offer free charging at certain locations, though availability depends on where you live and work.
Home charging: what you actually pay
If you install a charger at home — either a Level 1 charger (standard outlet) or a Level 2 charger (240-volt) — you pay your household electricity rate. A Tesla Model 3 uses roughly 25 kilowatt-hours to travel 100 miles. At the US average residential rate of about 14 cents per kilowatt-hour, that works out to roughly $3.50 per 100 miles, or about $0.035 per mile.
Your actual cost depends on three things: your local electricity rate, the efficiency of your specific Tesla model, and whether you charge during peak or off-peak hours. Some utilities offer lower rates for charging between 9 p.m. and 6 a.m., which can cut your cost by 30 to 50 percent if you shift your charging to those hours. Check your utility bill or your utility's website to find your rate and whether time-of-use pricing is available in your area.
Installing a home charger itself costs money upfront — a Level 2 charger typically runs $500 to $2,500 including installation, depending on your home's electrical setup. Some states and utilities offer rebates that cover part or all of this cost; your local utility or your state's energy office can tell you what is available where you live.
Tesla Supercharging: the paid network
Tesla's Supercharger network is designed for long trips, not daily charging. Superchargers add roughly 200 miles of range in 20 to 30 minutes. They cost money for the vast majority of Tesla owners, though the price structure has changed several times.
As of 2024, Supercharging costs between $0.25 and $0.50 per kilowatt-hour in most of the US, though prices are higher in some urban areas and lower in others. A full charge on a Model 3 (75 kilowatt-hours) would cost roughly $19 to $38, depending on location. Tesla's app shows the price at each Supercharger before you plug in, so you can see the exact cost for your location.
Some older Tesla owners still have free Supercharging as part of their original purchase agreement. If you bought a Tesla before 2017, or if you received free Supercharging as a promotional offer, you can check your account in the Tesla app to see whether the benefit is active. This perk does not transfer if you sell the car.
Free charging at work and public locations
Many employers, apartment buildings, shopping centers, and public parking facilities offer free Level 2 chargers to employees or customers. These chargers are slower than Superchargers — they typically add 25 to 30 miles of range per hour — but they are free to use. If you have access to a free charger at work or near home, you may rarely need to use a paid Supercharger.
Networks like Electrify America, EVgo, and ChargePoint operate public charging stations across the country. Some of these chargers are free, some charge per kilowatt-hour, and some charge per minute. Pricing and availability vary dramatically by location. Your Tesla's navigation system shows nearby chargers and their prices before you arrive, so you can plan accordingly.
How to estimate your total charging cost
To figure out what charging will cost you personally, start with how you drive. If you charge at home overnight most days and only use Superchargers on road trips a few times a year, your cost is almost entirely your home electricity rate. If you live in an apartment without home charging and rely on public chargers, your costs will be higher and more variable.
Use this rough math: take your annual miles driven, divide by your car's efficiency (usually 3 to 4 miles per kilowatt-hour for a Tesla), multiply by your local electricity rate for home charging or the Supercharger rate for long trips. A Tesla owner in California who drives 12,000 miles per year, charges at home at 20 cents per kilowatt-hour, and takes one road trip per year might spend roughly $600 to $800 on electricity annually. An owner in a state with cheaper electricity and no road trips might spend $300 to $400.
Comparing Tesla charging to gas car costs
Electricity is cheaper than gasoline per mile in nearly every US state. A Tesla Model 3 costs roughly $0.03 to $0.06 per mile to charge at home, depending on your electricity rate. A comparable gas car getting 30 miles per gallon costs roughly $0.10 to $0.14 per mile at current gas prices. Even Supercharging, which is more expensive than home charging, is usually cheaper per mile than gas.
The savings are largest if you charge at home and drive a lot. If you charge only at paid public chargers, the advantage shrinks but usually still exists. Over the life of a Tesla, home charging typically saves thousands of dollars compared to fueling a gas car.
Frequently Asked Questions
Do all Teslas come with free Supercharging?
No. Free Supercharging was included with some Tesla purchases made before 2017 and as a promotional offer at certain times, but it is not standard on new vehicles. You can check your Tesla app to see whether your account has free Supercharging active. If you do not see it listed, you will pay per use at Superchargers.
Can I charge my Tesla at a regular gas station?
No. Tesla Superchargers are proprietary to Tesla, and most public charging networks use different connectors. You can charge at some third-party networks like Electrify America or EVgo if your Tesla has the right adapter, but you cannot use a gas pump. Home charging requires a dedicated charger installed at your house or apartment.
What is the cheapest way to charge a Tesla?
Home charging at night during off-peak hours is almost always the cheapest option if your utility offers time-of-use rates. If you do not have home charging, free chargers at your workplace or shopping centers are next. Superchargers are the most expensive option and are best reserved for road trips when you need to charge quickly.
Does charging a Tesla overnight cost a lot?
Overnight home charging costs whatever your electricity rate is — typically $3 to $6 to fully charge a Model 3, depending on your region. This is much cheaper than Supercharging. If your utility offers lower rates during off-peak hours (usually 9 p.m. to 6 a.m.), charging overnight takes advantage of those savings automatically.
Will I save money switching from gas to a Tesla if I charge at home?
Almost certainly yes. Home charging costs roughly one-third to one-half what gas costs per mile in most states. Over five years of typical driving, the fuel savings alone can offset a significant portion of the higher purchase price of a Tesla compared to a gas car, especially when combined with lower maintenance costs.
