Determine how much it costs to charge your electric vehicle.
Estimate the total cost and cost per mile when charging from your current battery percentage to your target.
An EV charging cost calculator determines how much you'll spend to charge an electric vehicle from one battery state to another. Unlike gas vehicles, EV costs depend on electricity rates, battery capacity, charging efficiency, and driving distance.
The calculator takes your battery capacity in kWh, current and desired charge percentages, and local electricity rate. It calculates energy needed and multiplies by the rate to determine cost, then divides by driving range to show cost per mile.
Energy Needed (kWh) = Battery Capacity × (Desired SOC % − Current SOC %) ÷ 100. Total Charge Cost = Energy Needed × Electricity Rate. Cost per Mile = Total Charge Cost ÷ (Energy Needed × Miles per kWh).
Public stations add infrastructure, maintenance, and transaction costs. Home charging uses utility rates directly. Typical home charging costs $0.03-0.04/mile while public Level 3 costs $0.10-0.15/mile.
Higher speed charging is less efficient due to heat loss. Fast chargers also cost more per kWh, so higher speed = higher total cost per mile.
Check your vehicle's trip computer or mobile app. Real-world efficiency is typically 3-5 miles per kWh depending on driving conditions.
