The Formula

Gas cost = miles ÷ MPG × gas price; EV cost = miles ÷ 100 × kWh per 100 miles × electricity price

Understanding the EV vs. Gas Energy Cost Calculator

12,000 miles at 30 MPG and $3.50 gas costs $1,400; an EV at 30 kWh/100 miles and $0.15/kWh costs $540, saving $860.

Energy costs only: purchase price, insurance, maintenance, charger costs and charging losses are excluded.
