Cost to Charge an EV at Home Calculator: Home Charging Cost by State
Home charging is how most electric vehicle owners refuel, and it's almost always the cheapest option available. The cost to charge any EV at home comes down to three things: your battery size, how much of it you're refilling, and your local electricity rate. This calculator shows what a full home charge costs, your cost per mile, and your estimated monthly charging cost at your state's rate — for any EV, not just one brand.

How we calculate this →How home EV charging cost is calculated
The calculation starts with your usable battery capacity in kWh and your state's residential electricity rate. A full charge cost is simply battery × rate: a 65 kWh EV at $0.17/kWh costs about $11.05 per complete charge. Cost per mile follows from dividing the full charge cost by range — a 230-mile range makes each mile cost roughly 4.8 cents.
Monthly cost scales with how many miles you actually drive. If you cover 1,000 miles a month, you need 1,000 ÷ 230 ≈ 4.3 full-equivalent charges per month, using about 283 kWh. At the U.S. average rate that adds roughly $48 to your electricity bill.
A real Level 2 home charger (typically 7.2–11.5 kW) loses about 8–12% to heat during charging, so you'll pull slightly more kWh from the wall than the battery stores. This calculator uses the usable battery kWh as the baseline, which slightly understates actual electricity consumption — for a precise bill estimate, add 10% to the monthly kWh figure. Many utilities offer overnight EV time-of-use rates well below the residential average, which can cut monthly charging cost by 20–40%.
