Home EV Charger Electricity Cost Calculator

Charging an electric vehicle at home is almost always the cheapest way to fuel it — but it also becomes one of your home's largest single electricity uses. A Level 2 home charger draws around 7,200 watts while charging, and the monthly cost depends entirely on how many miles you drive. This calculator estimates what home charging adds to your electric bill per day and month at your state's rate, so you can see the true cost per mile on electrons.

Home EV charging costs and how to lower them

Level 2 home charging at 7,200 W (a 240V/30A circuit) adds roughly 25 miles of range per hour of charging. A typical 60–75 kWh EV battery takes 8–10 hours to charge from empty, but most drivers only add 20–50 miles per night, which is 1–2 hours of Level 2 charging.

Time-of-use (TOU) electricity rates can dramatically reduce EV charging costs. Overnight off-peak rates in California, New York, and other major TOU states can be 8–12¢/kWh versus 30–40¢ during peak evening hours. Scheduling your charger to run between midnight and 6 AM via your charger's app or smart home system can cut charging costs by 50–70% in TOU territories.

Frequently asked questions

For an average driver covering about 1,000 miles a month, home charging typically adds $30 to $60 to the electric bill at the U.S. average rate — far less than the equivalent gasoline cost. High-mileage drivers or high-rate states land higher.

It's a noticeable increase, but a cost-effective one. Charging shifts your fuel spending from the gas station to your electric bill, and because electricity per mile is usually far cheaper than gasoline, the total cost of driving generally drops even as the electric bill rises.

Often significantly. Many utilities offer special EV or time-of-use rates with much cheaper overnight prices. Scheduling your charger to run in those off-peak hours can cut home charging costs substantially compared with charging during peak times.
