How to Compare EV Charging Costs
EV charging costs vary significantly by method. Home charging typically costs $0.12–0.15/kWh in the US, while Level 2 public stations charge $0.20–0.35/kWh and DC fast chargers range from $0.35–0.60/kWh. Maximizing home charging can reduce your monthly energy costs by 60–70% compared to relying on fast chargers.
This calculator estimates your monthly energy consumption based on mileage and efficiency, then applies your charging mix to give a total monthly cost. Adjust the default rates to match your specific utility plan and preferred charging networks.
Frequently Asked Questions
Check PlugShare or your vehicle's trip computer for real-world mi/kWh data. EPA-rated efficiency is a good starting point, but actual efficiency varies with speed, weather, and driving style.
Frequent DC fast charging can slightly accelerate battery degradation over time. Most manufacturers recommend limiting fast charging to road trips and using Level 2 or home charging for daily use.
Rates vary by network and location. Tesla Supercharger, ChargePoint, and Electrify America pricing changes frequently. Always check the app before charging for the current rate at your specific location.
