EV vs gas in Maine
A Model Y charged at home costs $0.103 a mile. A 28 mpg gas car costs the same per mile when gas is $2.88 a gallon; at any higher pump price the EV is cheaper to run. Each $1 per gallon above that breakeven saves about $471 a year at 1,100 miles a month.
Public DC fast charging is a different story: at a typical $0.48/kWh it costs about $0.149 a mile ($164 a month), 1.4× the home rate. Charging mostly at home is what makes an EV cheap.

How the numbers are calculated
wall kWh = battery kWh × (target % − current %) ÷ charging efficiency
cost per charge = wall kWh × 32.41¢
cost per mile = rate ÷ (mi/kWh × efficiency)
breakeven gas price = cost per mile × 28 mpg
