Pick your EV and trip length. We split charging between home (your state's residential rate) and public fast chargers — then stack it against a gas car.
Math: trip kWh = miles × EPA kWh/100mi ÷ 90% charging efficiency. Home kWh at your state's EIA residential rate (June 2026); public kWh at your fast-charger price. Gas cost = miles ÷ mpg × gas price. Estimates — cold, speed, and terrain change real consumption.
