Charging a Tesla costs far less per mile than gasoline, but the total depends on your local electricity rates, where you charge, and which Tesla model you own.
A Tesla uses about 0.25 kilowatt-hours (kWh) of electricity per mile driven. If your home electricity costs $0.14 per kWh — the U.S. average as of 2024 — charging costs roughly $0.035 per mile. A gasoline car averaging 25 miles per gallon at $3.50 per gallon costs about $0.14 per mile. That means Tesla charging at home is typically one-quarter the cost of gasoline driving.
But the real cost depends on three things: where you charge (home, workplace, or public network), what you pay per kWh in your area, and how much battery capacity your specific Tesla model holds. A full charge on a Model 3 Standard Range costs less than a full charge on a Model S Long Range because the Model S has a larger battery.
Key Takeaways
- Home charging on a standard household circuit costs roughly $0.03 to $0.05 per mile in most U.S. states, depending on your local electricity rate.
- Installing a Wall Connector (240-volt charger) at home costs $500 to $2,500 including labor, but cuts charging time in half and lowers per-mile costs slightly.
- Public Supercharging networks cost $0.25 to $0.50 per kWh depending on location and time of day, making them more expensive than home charging but still cheaper than gasoline for most trips.
- Workplace charging and some retail locations offer free or low-cost charging, which can eliminate charging costs entirely for regular commuters.
- Your actual cost per mile varies by state — electricity is cheaper in Louisiana and Washington than in Hawaii or Massachusetts.
Home Charging Costs on a Standard Outlet
Charging a Tesla on a regular 120-volt household outlet (the kind you use for lamps and phone chargers) costs almost nothing upfront but takes a very long time. A Model 3 Standard Range adds about 2 to 3 miles of range per hour on a 120-volt outlet. A full charge from empty takes 24 to 30 hours.
The electricity cost itself is minimal. Using the national average of $0.14 per kWh, a full charge on a Model 3 Standard Range (which holds about 50 kWh) costs roughly $7. A Model Y Long Range (75 kWh) costs about $10.50. You pay nothing for the charger itself — it comes with the car.
Most owners use 120-volt charging only as a backup. If you drive fewer than 30 miles per day and can leave the car plugged in overnight, it works. If you drive more or need faster charging, you will want a dedicated home charger.
Home Charging with a Wall Connector (240-Volt)
A Wall Connector is a 240-volt charger that Tesla sells and installs at your home. It adds 25 to 30 miles of range per hour, meaning a full charge takes 8 to 10 hours instead of 24. Most owners plug in at night and wake up to a full battery.
Installation costs $500 to $2,500 depending on how far your electrical panel is from where you want the charger mounted and whether your home's electrical service needs an upgrade. If you already have 240-volt service (like for an electric dryer or air conditioning), the cost is usually on the lower end. If you need a new circuit or panel upgrade, expect the higher end.
The electricity cost per mile is nearly identical to 120-volt charging — about $0.03 to $0.05 per mile depending on your state. The Wall Connector is more efficient, but the difference is small. The real benefit is speed and convenience: you charge overnight instead of over two days.
Tesla also accepts third-party 240-volt chargers from companies like Chargepoint and Clipper Creek. These often cost less to install but may have different features or reliability records. Many owners choose the Wall Connector for simplicity.
Public Supercharging Network Costs
Tesla's Supercharger network is the fastest way to charge on the road. A Supercharger adds 200 miles of range in 15 to 20 minutes. Pricing varies by location and time of day, but typically ranges from $0.25 to $0.50 per kWh. Some locations charge by the minute instead, which costs $0.10 to $0.25 per minute depending on charging speed.
A full charge on a Model 3 at a Supercharger costs roughly $12 to $24. A Model Y costs $18 to $36. These prices are higher than home charging but still cheaper than gasoline for the same distance in most cases.
Supercharging is most expensive during peak hours (typically 4 p.m. to 9 p.m.) and cheapest during off-peak hours (late night and early morning). If you charge during off-peak times, you may pay 30 to 50 percent less. Tesla's in-car navigation shows real-time Supercharger prices before you arrive.
Long-distance road trips are where Supercharging makes sense. For daily commuting, home charging is almost always cheaper. If you use Superchargers for every charge, your per-mile cost rises to $0.08 to $0.15 — still less than gasoline in most cases, but significantly more than home charging.
Workplace and Retail Charging
Many employers, shopping centers, and parking garages offer free or low-cost charging. Workplace charging is often free because employers want to attract employees and reduce parking pressure. Retail locations like grocery stores and malls sometimes offer free charging as an incentive to shop there.
These chargers are usually Level 2 (240-volt), similar to a home Wall Connector. They add 20 to 30 miles of range per hour. If you charge for 2 to 4 hours while at work or shopping, you can add 40 to 120 miles of range at no cost.
For commuters who drive 30 to 50 miles per day, free workplace charging can eliminate charging costs almost entirely. You charge at home overnight for the commute, charge free at work during the day, and rarely use paid Supercharging. This is the lowest-cost scenario for regular driving.
How Electricity Rates in Your State Affect Total Cost
Your state's electricity rate is the biggest variable in home charging cost. Louisiana has the cheapest electricity at roughly $0.10 per kWh. Hawaii has the most expensive at roughly $0.35 per kWh. This means a full charge on a Model 3 costs $5 in Louisiana but $17.50 in Hawaii.
The following table shows approximate home charging costs per mile in different regions:
| Region / State | Average Rate per kWh | Cost per Mile (Model 3) |
|---|---|---|
| Louisiana, Washington | $0.10–$0.12 | $0.025–$0.030 |
| Texas, Oklahoma, Kansas | $0.12–$0.14 | $0.030–$0.035 |
| National average | $0.14 | $0.035 |
| New York, Illinois, Ohio | $0.14–$0.16 | $0.035–$0.040 |
| California, Massachusetts | $0.18–$0.22 | $0.045–$0.055 |
| Hawaii | $0.35 | $0.088 |
Even in Hawaii, charging costs less per mile than gasoline. But if you live in a state with high electricity rates and use Superchargers frequently, your per-mile cost approaches gasoline prices. Home charging in any state remains the cheapest option.
Time-of-Use Electricity Plans and Off-Peak Charging
Some utilities offer time-of-use (TOU) rates, which charge less per kWh during off-peak hours (usually 9 p.m. to 6 a.m.) and more during peak hours. If your utility offers TOU rates, charging at night can cut your electricity cost by 20 to 40 percent.
For example, if peak rates are $0.18 per kWh and off-peak rates are $0.10 per kWh, charging during off-peak hours saves roughly $0.002 per mile. Over 12,000 miles per year, that is about $24 in savings. For some owners, especially those with high electricity rates, switching to a TOU plan and charging at night pays for itself within a year or two.
Ask your utility whether TOU rates are available in your area. Many utilities now offer them specifically for electric vehicle owners. Tesla's Wall Connector can be set to charge only during off-peak hours if you want to automate this.
Comparing Total Ownership Cost: Tesla vs. Gasoline
Charging costs are only one part of the picture. A Tesla owner also saves on oil changes, transmission fluid, spark plugs, and other maintenance items that gasoline cars need. Brake wear is also lower because Teslas use regenerative braking, which captures energy when slowing down.
Over 200,000 miles, a typical gasoline car costs roughly $4,000 to $6,000 in fuel. The same distance in a Tesla costs roughly $1,500 to $2,500 in electricity, depending on your state and charging mix. That is a savings of $2,500 to $4,500 in fuel and electricity costs alone.
However, Teslas cost more upfront than comparable gasoline cars. A Model 3 starts around $40,000; a comparable gasoline sedan costs $25,000 to $30,000. The fuel and maintenance savings narrow that gap over time, but it takes 5 to 7 years of driving to break even on the purchase price difference in most cases.
Frequently Asked Questions
Does Tesla charge for using the Supercharger network?
Yes. Supercharging costs $0.25 to $0.50 per kWh or $0.10 to $0.25 per minute depending on the location. Prices are highest during peak hours and lowest late at night. Some older Teslas purchased before 2017 have unlimited free Supercharging for life, but all new Teslas are charged per use.
Can I charge my Tesla at a regular gas station?
No. Tesla Superchargers are proprietary to Tesla vehicles. You can charge at third-party networks like Electrify America or Chargepoint, but these require a separate membership or payment method and may have different pricing. Most owners use Superchargers for road trips and home charging for daily driving.
What happens if I charge my Tesla every day at home?
Your electricity bill will increase by roughly $30 to $50 per month if you drive 1,000 miles per month (a typical commute). This assumes home charging at the national average electricity rate. The exact amount depends on your state's rates and how much you drive.
Is it cheaper to charge at night?
Only if your utility offers time-of-use rates with lower off-peak pricing. If you have a standard flat rate, charging at night costs the same as charging during the day. Check with your utility to see whether TOU rates are available in your area.
Do I need to pay to install a home charger?
Yes. A Wall Connector installation costs $500 to $2,500 depending on your home's electrical setup. Some states and utilities offer rebates of $500 to $2,000 for installing a home charger, which can offset part or all of the cost. Check your state's energy office or utility website for current rebate programs.
