EV Home Charging Cost Calculator
Estimate monthly and annual home EV charging cost from vehicle efficiency, annual mileage, charging losses, and your state electricity rate.
EV operating-cost model
Calculate electricity cost per mile and per year
Battery-side driving energy: 3600 kWh/year. Estimated grid energy after charging losses: 3960 kWh/year.
Model note
Use your vehicle's real numbers when possible
Use the vehicle's EPA or dashboard efficiency when available. Charging losses represent energy drawn from the wall that does not become stored battery energy.

What can change the result
Charging and driving vary
Weather, speed, cabin climate, battery conditioning, elevation, charger efficiency, and onboard-charger limits can change real energy use.
Formula used
Battery energy = miles ÷ 100 × kWh/100 mi. Grid energy adds charging losses. Cost = grid kWh × electricity price.
Use the exact residential rate from your utility bill when available.
