How Much Does It Really Cost to Charge an EV at Home? — July 2026
A home EV charger is, electrically, just another large appliance — the same kW × hours × price formula every load on this site uses. What makes it different is scale: a Level 2 charger draws far more power than almost anything else in the house, so it moves your bill by state-price differences that a smaller appliance would never show. This covers Level 2 home charging only — public DC fast charging is priced and billed differently, and is not covered here.
The monthly cost, by state price
At 7,200 W (a 240V/30A Level 2 charger) for 3 hours a day — a full overnight charge, not necessarily every night — at each state's official average residential rate for July 2026:
Cheapest 5 states
| Louisiana | $82.43 |
| Nevada | $82.75 |
| Utah | $85.02 |
| North Dakota | $86.90 |
| Tennessee | $88.84 |
Priciest 5 states
| Hawaii | $311.04 |
| California | $217.79 |
| Maine | $210.02 |
| Massachusetts | $197.58 |
| New York | $193.75 |
The full table for all 50 states and D.C., plus a calculator for your own hours and rate, is on the EV charger cost-to-run page.
Turning that into a cost per mile
A monthly charging bill only means something once you can compare it to what you actually drive. EPA-style efficiency testing reports EV consumption in miles per kWh, and it varies by vehicle — for illustration here, we use 3.5 miles per kWh, a figure in range for a well-performing modern midsize EV (some compact EVs do noticeably better, some larger ones noticeably worse — check your own vehicle's EPA rating for a real number). At that efficiency:
cost per kWh ÷ 3.5 mi/kWh = cost per mile
Example — Louisiana: 12.72¢/kWh ÷ 3.5 ≈ $0.036/mile
Run the same division with your own state's price (from the table above or your state page) and your own vehicle's rated mi/kWh for a number that actually applies to you, then compare it to what you were paying per mile in gas — the arithmetic is the same, just with a different price and a different efficiency figure.
What changes the number most
- Off-peak charging, if your utility offers it. A time-of-use rate can price overnight charging well below the flat average used above — ask your utility whether an EV or off-peak rate plan exists before assuming the standard rate is your only option.
- How often you actually charge to full. The table assumes a full session; most days only replace what was driven, which is usually a fraction of a full charge — use the calculator on the cost-to-run page to enter your own typical hours.
- Level 1 vs. Level 2 changes speed, not the total energy cost. A standard 120V outlet (Level 1) charges far more slowly than a 240V Level 2 charger, but for the same number of kWh delivered, the electricity cost is the same — the difference is only how many hours it takes to deliver them.
- Whether you are in a deregulated state. See deregulated vs. regulated states for whether shopping for a lower supply rate is even an option where you live.

Assumes a 30-day month (year = 12 × month) at Ohio's average residential rate of 19.45¢/kWh (U.S. EIA, July 2026). Your plan's price differs.
Typical wattage: 7,200 W (DOE Energy Saver, verified 2026-07-17) — 240 V / 30 A Level 2 ~7,200 W. A representative figure, not a spec sheet for your model.
