Using the U.S. Energy Information Administration’s preliminary 2025 average residential electricity price of 17.30 cents per kilowatt-hour, 100 kWh of home charging would cost about $17.30. Your actual bill depends on your utility rate, how far you drive, and how much electricity your EV uses. The 2025 average was published in 2026; it is a benchmark, not a forecast or a personalized rate.
How to calculate your home charging cost
Use the electricity your car draws from your home—not just the energy stored in its battery—and multiply it by the price you pay per kilowatt-hour (kWh):
Charging cost = kWh drawn from the home × electricity price per kWh
At the EIA’s 2025 U.S. residential average of 17.30 cents per kWh, 100 kWh costs $17.30 and 300 kWh costs $51.90. Those are arithmetic examples, not estimates of a typical driver’s monthly use. The EIA’s 2025 figures are preliminary data published in 2026. See the EIA explanation of electricity prices and its Electric Power Monthly table.

Battery size is not the same as electricity drawn
A battery’s capacity is a useful starting point for estimating a refill, but it does not capture charging losses. Some electricity is lost between the wall and the battery, so the home’s meter can record more energy than the battery stores. For a more accurate calculation, use charging energy reported by your vehicle, app, or charger when available. For background on charging losses, see EnergySage’s EV charging cost explanation.
Estimate cost per mile, then scale to your driving
EV efficiency is often expressed as kWh per 100 miles. The U.S. Department of Energy Alternative Fuels Data Center (AFDC) uses that measure and illustrates the calculation with 27 kWh per 100 miles at 10.7 cents per kWh: about 2.9 cents, or roughly 3 cents, per mile. That is a DOE example using its stated rate—not a current universal price.

- WORKS WITH EVERY NON-TESLA EV: Standard J1772 connector plugs straight into Ford, Chevrolet, Hyundai, Kia, Nissan, BMW, Volkswagen, Audi, Rivian, Lucid and every other EV or plug-in hybrid sold with a J1772 port - no adapter needed. Tesla drivers can charge too, using the J1772 adapter that comes with the car.
- PLUG IN, NO HARDWIRING: Level 2 charger delivers up to 40A to fully charge most EVs overnight. Plugs into a 240V, 4-prong NEMA 14-50 outlet (the RV/range type - NOT a dryer outlet) on a dedicated 50A circuit. The extra-long 25 ft cable easily reaches across a garage or driveway. Before ordering, check your car's port type and that you have the right outlet.
- CONTROL & SAVE FROM YOUR PHONE: A stronger built-in antenna keeps the charger online even in a garage or basement. Use the free app to start/stop charging, set speed (6-40A), get reminders, and track energy use and cost. Schedule off-peak overnight charging to cut your electric bill. Requires 2.4 GHz WiFi.
- SAFETY-CERTIFIED & WEATHERPROOF: Independently tested and certified (UL, ETL, FCC, Energy Star). A fully sealed IP66 / NEMA 4 housing stands up to rain, snow, heat and dust indoors or out, and internal steel shielding protects the electronics for years of reliable use.
- GLOW-IN-THE-DARK HOLSTER: The included high-visibility holster glows in the dark so you can find and dock the plug easily at night. Holds the connector securely when not in use.
To calculate your own energy cost per mile, multiply your vehicle’s kWh per 100 miles by your electricity price per kWh, then divide by 100. To estimate a month, multiply that per-mile cost by the miles you expect to drive. If your vehicle or charger reports monthly kWh drawn from the home, multiplying that figure by your tariff is more direct. The DOE’s home charging guidance also gives a separate illustration: at 10.7 cents per kWh, refilling a depleted 54-kWh battery would cost about $6, while noting that actual home charging costs depend on equipment, time of day, and charging duration.
Why your local electricity rate matters
The national residential average is only a reference point. Use the rate on your own bill or utility tariff for a household estimate. In 2025, the EIA’s average across all utility customer classes was 13.63 cents per kWh, lower than the 17.30-cent residential average; the all-customer figure should not be substituted for a home rate. The EIA’s reported 2025 state range of 8.20 to 35.72 cents per kWh also covers all customer classes, not residential customers alone. These 2025 figures are preliminary data published in 2026.

Electricity prices vary with factors including fuel availability, local costs, and regulation. Most consumers pay prices based on seasonal average costs, while some utilities offer time-of-day pricing. If your utility has an off-peak rate, compare its hours and price with your charging schedule rather than assuming overnight charging is automatically cheaper. Check your utility’s current tariff and eligibility for any EV-specific rate or incentive; offerings are local and can change. EIA’s price overview and monthly data table and notes provide the broader context.

A dedicated Level 2 charger is optional; whether it is worthwhile depends on your charging needs, vehicle, and home electrical capacity. Level 2 equipment can charge faster than Level 1, but a higher-rated charger will not make a car charge faster than the car’s own maximum AC charging rate. EPA guidance describes Level 2 chargers as rated from 16 to 80 amps and recommends considering both the vehicle and the home when selecting equipment. See the EPA’s plug-in vehicle charging details.

Before installing equipment, check whether your electrical service can support it, whether the installation requires a permit under local rules, and whether the equipment is rated for its location. The DOE AFDC advises following applicable electrical codes and local permitting requirements; outdoor installations need outdoor-rated equipment. A Level 2 charger does not lower the utility’s per-kWh price by itself. If you compare units, check vehicle compatibility, amperage, installation requirements, outdoor rating if relevant, warranty, and any utility incentive available to you. The DOE AFDC home charging guidance covers installation considerations.
What to use for a realistic estimate
- Your electricity price: Use the applicable residential rate or time-of-use price from your bill or utility tariff.
- Your charging energy: Prefer kWh drawn from the home as reported by the vehicle, app, or charger; account for charging losses if estimating from battery capacity.
- Your driving: Use your actual monthly miles and the vehicle’s efficiency in kWh per 100 miles if you do not have a monthly charging-energy figure.
The EPA puts the basic bill impact plainly: “If you charge at home, the cost will be included in your monthly electric bill, just like you pay for the electricity use of home appliances.”
