About This Calculator
This calculator estimates the cost of a full charge for an electric vehicle based on your battery's usable capacity, your electricity rate, and typical charging losses, then converts that into a cost-per-mile figure using your EV's efficiency rating.
How This Is Calculated
Cost = (Battery Capacity ÷ Charging Efficiency) × Electricity Rate
- Charging Efficiency
- — Percentage of grid energy that actually reaches the battery, typically 85-90%
A 75 kWh battery at $0.16/kWh with 88% efficiency costs about $13.64 for a full charge, covering roughly 262 miles at 3.5 mi/kWh.
Assumptions
- Uses a home electricity rate; public charging (especially DC fast charging) is typically more expensive per kWh.
- Charging efficiency accounts for energy lost as heat, not battery degradation over time.
