The real cost depends on your local electricity rate and which Tesla model you own

A full charge for a Tesla costs between $8 and $25 at home, depending on your regional electricity price and which model you drive. The math is straightforward: take your car's battery size in kilowatt-hours (kWh), multiply it by your local electricity rate per kWh, and add about 10 percent for charging losses. A Model 3 with a 75 kWh battery in a state where electricity costs $0.15 per kWh will cost roughly $12.38 to charge fully. The same car in a state where electricity costs $0.25 per kWh will cost about $20.63.

Public charging networks charge differently — some by the minute, some by the kWh delivered, and some with a flat session fee. Supercharging (Tesla's fast-charging network) typically costs $0.25 to $0.50 per kWh depending on location and time of day, which means a full charge might run $18 to $37. Third-party networks like Electrify America or EVgo often cost $0.30 to $0.43 per kWh. Home charging is almost always cheaper than public charging, which is why most Tesla owners do the bulk of their charging overnight at home.

Key Takeaways

  • Home charging costs $8 to $25 per full charge for most Tesla models, calculated by multiplying your battery size by your local electricity rate.
  • Your electricity rate varies by state and utility company, so you should check your own bill to calculate your exact cost.
  • Supercharging costs roughly two to three times more per kWh than home charging, but is useful for long trips when you need speed over cost.
  • A Tesla Model 3 costs about one-third to one-half as much to charge as a gas car costs to fill up, depending on gas prices and your electricity rate.

How to find your own electricity rate

Your electricity bill shows your rate per kWh, usually listed as a per-kWh charge separate from fixed monthly fees. Look for a line item labeled "energy charge," "per kWh rate," or "usage rate." Rates vary widely — California averages around $0.20 per kWh, while Louisiana averages around $0.10 per kWh. Some utilities charge different rates depending on the time of day (time-of-use rates), so charging at 2 a.m. might cost less than charging at 6 p.m.

Once you have your rate, find your Tesla's battery size. The Model 3 Standard Range Plus has a 54 kWh usable battery, the Model 3 Long Range has 75 kWh, and the Model 3 Performance has 75 kWh. Model Y sizes range from 60 kWh to 82 kWh depending on the version. Tesla's website lists the battery size for each model. Multiply the battery size by your electricity rate, then add 10 percent to account for charging losses (energy lost as heat during the charging process). That gives you your home charging cost.

Supercharging costs and when it makes sense

Tesla Superchargers are located along highways and in cities, designed for fast charging during long trips rather than daily use. Supercharging costs vary by location and time of day, typically ranging from $0.25 to $0.50 per kWh. A Model 3 Long Range (75 kWh) charged at $0.35 per kWh would cost about $26 for a full charge. Supercharging is most economical when you charge only to 80 percent, because charging slows dramatically after that point — the last 20 percent takes nearly as long as the first 80 percent but costs more per kWh.

For daily driving, Supercharging is expensive compared to home charging. But for road trips, it is the practical choice because it delivers 200 miles of range in 20 to 30 minutes. If you drive 50,000 miles per year and Supercharge everything, your charging cost would be roughly $1,500 to $2,500 annually. If you charge at home for daily driving and Supercharge only on road trips, your annual cost drops to $400 to $800.

Third-party charging networks and workplace charging

Networks like Electrify America, EVgo, and Volta operate charging stations in parking lots, shopping centers, and along highways. Pricing varies by network and location. Electrify America charges $0.30 to $0.43 per kWh at most locations. EVgo charges $0.28 to $0.45 per kWh. Some networks charge a monthly membership fee ($4 to $15) that lowers the per-kWh rate. A full charge at a third-party network typically costs $18 to $32, making it more expensive than home charging but sometimes cheaper than Supercharging.

Workplace charging is often free or heavily subsidized by employers, which can cut your charging costs significantly if your workplace has a charger. Some apartment buildings and condos offer charging as an amenity. If you have access to free or low-cost charging at work or home, your annual charging cost can drop below $400 even with moderate driving.

Comparing Tesla charging to gas car fuel costs

A Tesla Model 3 uses about 0.25 kWh per mile, meaning a 300-mile charge uses 75 kWh. At $0.15 per kWh, that 300-mile charge costs $11.25, or about $0.04 per mile. A gas car averaging 30 miles per gallon costs about $0.10 to $0.13 per mile when gas is $3 to $4 per gallon. Over 100,000 miles, the difference is substantial — a Tesla costs roughly $4,000 to $5,000 in electricity, while a gas car costs $10,000 to $13,000 in fuel.

The savings are largest in states with low electricity rates and smallest in states with high rates. In Louisiana (low electricity cost), a Tesla costs about $2,500 to drive 100,000 miles. In California (high electricity cost), the same car costs about $5,000. Even at California rates, a Tesla is still cheaper to fuel than most gas cars.

Charging at home: equipment and installation costs

Most Tesla owners charge at home using a Wall Connector, which is a 240-volt charger that Tesla sells for about $500 to $600 before installation. Installation typically costs $500 to $2,000 depending on whether your home's electrical panel needs an upgrade. A standard 120-volt outlet (the kind in most homes) can charge a Tesla, but it adds only 2 to 3 miles of range per hour, making it impractical for daily use.

The Wall Connector adds 25 to 30 miles of range per hour, so a full charge overnight is realistic. If you install a Wall Connector, your charging cost is just the electricity itself — no session fees, no time-of-use surcharges. Over five years, home charging saves thousands compared to relying on public networks. Some utilities and state programs offer rebates for home charger installation, which can offset part of the equipment and labor cost.

Frequently Asked Questions

Does charging overnight cost less than charging during the day?

It depends on your utility's pricing structure. Many utilities offer time-of-use rates where electricity is cheaper during off-peak hours (typically 9 p.m. to 6 a.m.). If your utility offers this, charging at night can save 20 to 40 percent compared to daytime charging. Check your electricity bill or contact your utility to see if time-of-use rates are available in your area.

How much does it cost to charge a Tesla at a public charger versus at home?

Home charging costs $8 to $25 per full charge depending on your electricity rate. Public chargers cost $18 to $37 for a full charge at Superchargers, or $18 to $32 at third-party networks. Home charging is almost always cheaper, which is why most owners do daily charging at home and use public chargers only for road trips.

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

A Level 2 charger (like Tesla's Wall Connector) uses 240-volt power and adds 25 to 30 miles of range per hour, suitable for overnight home charging. A Supercharger uses 480-volt power and adds 200 miles of range in 20 to 30 minutes, designed for road trips. Superchargers cost more per kWh but are much faster.

Can I charge my Tesla with a regular outlet?

Yes, but it is slow. A standard 120-volt outlet adds only 2 to 3 miles of range per hour, so a full charge takes 40 to 50 hours. This works if you drive very little or have access to charging for extended periods, but most owners find it impractical for daily use and install a 240-volt charger instead.

Does cold weather increase charging costs?

Cold weather does not change the per-kWh cost, but it does reduce the usable battery range, meaning you need to charge more often to drive the same distance. Cold also slows charging speed, so you may spend more time plugged in. The electricity cost per mile driven increases slightly in cold weather, but the per-kWh rate itself stays the same.
