This calculator estimates annual EV charging costs based on your driving habits and electricity rates. Energy consumption is calculated as (annual miles / 100) × EV efficiency (kWh/100mi). Costs are split between home and public charging based on your specified percentages. For time-of-use (TOU) rates, the effective rate is the weighted average of off-peak and on-peak rates. Gas comparison uses standard MPG calculations. Charging times are estimated at 1.4 kW for Level 1 and 7.6 kW for Level 2. CO₂ savings use EPA averages: 0.855 lbs CO₂/kWh for the grid and 19.6 lbs CO₂/gallon of gasoline.
