Gas cost per mile
gas = price per gallon ÷ mpg
$3.2 ÷ 30 = $0.106667
EV cost per mile
EV = kWh/100 mi ÷ 100 × $/kWh × (1 + losses ÷ 100)
30 ÷ 100 × $0.16 × (1 + 0 ÷ 100) = $0.048
Yearly difference
(gas − EV) × miles a year
($0.106667 − $0.048) × 12,000 = $704.00
How it works
Gas cost per mile = price per gallon ÷ mpg; EV cost per mile = kWh per 100 mi ÷ 100 × price per kWh × (1 + charging loss); yearly cost = cost per mile × miles per year
