What you pay to charge a Tesla depends on where you charge and your local electricity rates
Charging a Tesla at home typically costs between $0.03 and $0.05 per mile of range, though this varies based on your regional electricity rates. At a public fast-charging station, you might pay $0.25 to $0.50 per mile, or sometimes a flat fee per session. The actual dollar amount depends on three things: your local cost of electricity, the Tesla model you own, and whether you're using a home charger, a Supercharger, or a third-party network.
Most Tesla owners charge at home overnight using a standard outlet or a dedicated home charger, which is almost always cheaper than public charging. If you drive 12,000 miles per year and charge mostly at home, your annual charging cost might be $400 to $600. The same driving at public fast-charging stations could cost $2,000 to $3,000 per year, though most owners use a mix of both.
Key Takeaways
- Home charging costs less per mile than public charging because residential electricity rates are lower than the markup at charging stations.
- A Level 2 home charger (240 volts) costs $500 to $2,500 to install but pays for itself through lower per-mile costs within a few years.
- Tesla Superchargers charge faster than other networks but may cost more, and pricing varies by location and time of day.
- Your actual cost per mile depends on your local electricity rate, which you can find on your utility bill or your provider's website.
- Public charging networks like Electrify America and EVgo often charge by the minute or kilowatt-hour, so speed of charging affects your total cost.
Home charging costs and what affects the price
Charging at home is the cheapest option for most owners because you're paying your residential electricity rate, not a markup. To find your rate, look at your utility bill — it's usually listed as cents per kilowatt-hour (kWh). A Tesla Model 3 uses roughly 25 kWh to go 100 miles, so if your rate is $0.14 per kWh, charging 100 miles costs about $3.50.
The charger you use at home matters for speed and convenience, but not for the per-kWh cost — you're always paying your utility rate. A standard 120-volt outlet (the kind in most homes) charges slowly, adding about 2 to 3 miles of range per hour. A Level 2 charger (240 volts) adds 25 to 30 miles per hour and requires installation by an electrician, which costs $500 to $2,500 depending on how far your electrical panel is from where you want the charger. Many owners find the faster charging worth the upfront cost, especially if they drive daily.
Some utilities offer time-of-use rates, where electricity costs less during off-peak hours (usually late night or early morning). If your utility offers this, charging between 9 p.m. and 6 a.m. could cut your per-mile cost in half. Check your utility's website or call to ask whether this option is available in your area.
Tesla Supercharger pricing and how it works
Tesla Superchargers are the fastest public option, adding 200 miles of range in about 20 to 30 minutes. Pricing varies by location and time of day — some stations cost more during peak hours (typically 4 p.m. to 9 p.m.). You pay through the Tesla app, and the charge appears on your Tesla account. Most Superchargers cost between $0.25 and $0.50 per mile, though some busy urban locations charge more.
Supercharging is most economical for road trips, not daily charging. If you use Superchargers for most of your driving, your per-mile cost will be significantly higher than home charging. Tesla also offers a Supercharging subscription plan in some regions, which gives you a lower per-kWh rate if you charge frequently at their network.
Supercharger pricing is posted in the app before you plug in, so you can see the exact cost. Some stations charge by the minute after you reach 80% charge (when charging slows), which means staying plugged in longer costs more. Unplugging at 80% and moving on is usually cheaper if you're in a hurry.
Third-party public charging networks and their costs
Networks like Electrify America, EVgo, and Chargepoint operate thousands of public chargers across the country. These charge by the kilowatt-hour (kWh), by the minute, or sometimes a flat fee per session. Costs typically range from $0.20 to $0.45 per kWh, which translates to roughly $0.15 to $0.40 per mile depending on your car's efficiency.
Many of these networks charge more per minute after you reach 80% charge, so the cost accelerates if you stay plugged in. Some offer membership plans that lower the per-kWh rate if you charge regularly. Electrify America, for example, has a membership option that reduces costs for frequent users. You can compare networks using apps like PlugShare or A Better Route Planner, which show real-time pricing at nearby stations.
The cheapest third-party option is often a Level 2 charger at a shopping center, parking garage, or workplace, which may charge $1 to $3 per session or nothing at all. These charge slowly (25 to 30 miles per hour) but cost far less than fast-charging if you have time to wait.
How to calculate your personal charging cost
Start with your electricity rate in cents per kWh — this is on your utility bill. Then find your car's efficiency, which the Tesla app shows as miles per kWh or kWh per 100 miles. Multiply your rate by your car's consumption to get the cost per mile. For example: $0.14 per kWh × 0.25 kWh per mile = $0.035 per mile.
For public charging, the math is simpler if the station posts a per-kWh price. Use the same formula. If the station charges by the minute, you need to know how many kWh you're adding per minute, which varies by charger speed and your car's battery state. Most fast-chargers add 10 to 20 kWh per minute at peak speed, so a $0.50-per-minute charger costs roughly $0.25 to $0.50 per kWh.
Keep a record of a few charging sessions — note the kWh added and the cost — to see your actual average. This is more accurate than estimates because real-world efficiency varies with temperature, driving style, and how full your battery was when you started.
Comparing home charging to gas and other options
A Tesla Model 3 costs roughly $3 to $5 to charge fully at home, depending on your electricity rate. A comparable gas car costs $12 to $15 to fill up. Over 12,000 miles per year, home charging saves most owners $800 to $1,200 annually compared to gas. Even if you use public fast-charging for half your driving, you typically still save money versus gas.
The upfront cost of a home charger ($500 to $2,500) usually pays for itself within two to four years through lower per-mile costs. If you plan to keep the car longer, the savings compound. If you rent or live in an apartment without dedicated parking, public charging is your main option, and your per-mile cost will be higher — but still often cheaper than gas.
Frequently Asked Questions
How much does it cost to charge a Tesla overnight at home?
A full charge for a Model 3 or Model Y costs roughly $3 to $5 at home, depending on your local electricity rate. If your rate is $0.12 per kWh and your car uses 50 kWh to charge fully, the cost is $6. Most owners charge overnight using a Level 2 charger and pay their standard residential electricity rate.
Is it cheaper to charge at home or at a Supercharger?
Home charging is almost always cheaper per mile. Supercharging costs roughly 5 to 10 times more per mile than home charging for most owners. Use Superchargers for road trips, not daily driving. If you charge mostly at home and use Superchargers occasionally, your average cost stays low.
Do I need to install a home charger, or can I use a regular outlet?
A regular 120-volt outlet works but charges very slowly — about 2 to 3 miles per hour. If you drive less than 30 miles per day and can wait overnight, a standard outlet may be enough. For daily driving, most owners install a Level 2 charger (240 volts) for faster overnight charging.
What's the difference between charging by the minute and by the kilowatt-hour?
Charging by the minute means you pay a flat rate per minute, so staying plugged in longer costs more. Charging by the kWh means you pay for the energy you use, regardless of time. By-the-minute pricing can be cheaper if you charge quickly to 80%, but more expensive if you stay plugged in longer.
Can I reduce my charging cost with a time-of-use electricity plan?
Yes, if your utility offers it. Time-of-use plans charge less during off-peak hours (usually late night) and more during peak hours. Charging between 9 p.m. and 6 a.m. can cut your per-mile cost in half. Contact your utility to ask whether this plan is available and what the rates are.
