EV vs Gas Car Fuel Cost Comparison Calculator
Prospective EV buyers calculating total cost of ownership (TCO). Calculates cost per mile, monthly fuel expenses, and annual dollar savings of driving an Electric Vehicle compared to an internal combustion engine vehicle.
Step-by-Step Derivation ▼ Show Steps
Calculations adhere to standard electrical engineering physics and National Electrical Code (NFPA 70) regulations.
Engineering Principles & Calculations
This calculator uses the exact mathematical relationships between Annual Mileage, Gas Price ($/Gallon), Gas Car Fuel Economy (MPG), Home Electricity Rate ($/kWh), EV Efficiency (miles/kWh or kWh/100mi) to determine EV Cost per Mile ($), Gas Cost per Mile ($), Annual Savings ($), 5-Year Fuel Savings ($). In practical installations, factors such as ambient raceway temperature, harmonic distortion, duty cycle continuous operation, and conductor impedance must be accounted for by a certified electrician.
