How Much Does It Cost to Charge a Tesla at Home? (2026)

Short answer: charging a Tesla at home costs about $12 to $16 for a full charge of a Model 3 or Model Y at the 2026 US average electricity price of 18.2¢ per kWh, or about 5¢ a mile. Driving 1,000 miles a month in a Model 3 costs about $51, roughly half what a 30 mpg petrol car spends on fuel. On a cheap overnight EV rate, it can cost a third of that.

To work out your own figure with your car, miles and tariff, use the EV charging cost calculator.

Cost to charge each Tesla at home

At 18.2¢ per kWh, allowing about 10% for charging losses on a Level 2 (240 V) home charger:

Tesla does not publish exact battery capacities, so these are rounded estimates that vary by model year. Cost per mile uses approximate EPA consumption: about 25 kWh per 100 miles for a Model 3 RWD, rising to about 42 for a Cybertruck. Your real figure will be higher in winter and at motorway speeds.

The formula

cost of a charge = battery kWh added ÷ 0.9 × price per kWh
cost per mile    = kWh per mile ÷ 0.9 × price per kWh

The ÷ 0.9 adds back the roughly 10% of energy lost as heat in the charger and battery. On a standard 120 V outlet (Level 1), losses are often 15% or more, which adds about $3 to a 1,000-mile month for a Model 3.

Cost by country

For a Model 3 (about 0.25 kWh per mile) driving 1,000 miles (1,609 km):

In kilometres, that is about 2.4¢ per km in Canada and 5.5¢ per km in Australia.

Home charging vs Superchargers

Supercharger prices vary by site and time of day, typically about $0.30 to $0.45 per kWh in the US, and other DC fast-charging networks average roughly $0.45 to $0.50. At those prices, the same 1,000 miles in a Model 3 costs about $83 to $125: two to two and a half times the cost of charging at home. Superchargers make sense on road trips; for everyday driving, home charging is far cheaper.

How to cut the cost

• Charge off-peak. Many US utilities offer time-of-use or EV rates, and UK EV tariffs can drop to around 7p to 9p per kWh overnight. Set a scheduled charging time in the Tesla app.
• Use a Level 2 charger rather than a standard outlet: it is faster and wastes less energy.
• Precondition while plugged in on cold mornings so the battery and cabin are warmed from the grid, not from your range.
• Add solar. If you have solar panels, charging during the day uses electricity you would otherwise export for much less. The solar panel calculator shows how many panels an EV adds.

Frequently asked questions

How much does it cost to charge a Tesla at home per month?

About $50 to $60 for 1,000 miles a month in a Model 3 or Model Y at the US average price. Multiply your monthly miles by about 5¢ for a Model 3, or use the calculator with your own rate.

Does charging a Tesla raise your electric bill a lot?

A typical US driver (about 13,000 miles a year) adds roughly 300 kWh a month, about a third more than the average home's 865 kWh. On an off-peak rate the cost increase is much smaller.

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

Home is usually two to three times cheaper. Superchargers are priced for convenience and speed.

Should I charge to 100%?

Tesla recommends a daily limit (often 80% to 90%) for most battery types and 100% only before long trips; check the guidance for your car. Charging to a lower limit costs less each time but not less per mile.
