EV Annual Electricity Cost Calculator
Calculate yearly EV electricity cost from miles driven, kWh per 100 miles, charging losses, and residential electricity price.
EV operating-cost model
Calculate electricity cost per mile and per year
Battery-side driving energy: 4500 kWh/year. Estimated grid energy after charging losses: 4950 kWh/year.
Model note
Use your vehicle's real numbers when possible
The calculator treats kWh/100 mi as battery-side vehicle energy use and adds an adjustable charging-loss percentage to estimate grid 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.
