Electric Vehicle Charging Calculator

Calculate how long it takes to charge your electric vehicle between two percentage points.

Battery capacity (Total) kWh Starting charge % 0% Goal charge % 100% Charging speed W

Electricity cost per kilowatt-hour $

This is a rough calculation. It assumes a constant charging rate between your specified start and goal percentages and doesn't account for battery health or degradation, battery or ambient temperature, the vehicle's charging curve and power taper, thermal management, DC fast-charging power limits, firmware limits (like capping at 80%), or any other real-world variable that might affect charging.

The gasoline figure is a straight energy comparison — a US gallon of gasoline holds about 33.7 kWh of energy — and ignores how efficiently each powertrain actually uses it.
