EV Charge Charging a Tesla Model Y at home in Idaho costs about $37 per 1,000 miles, or $0.037 per mile, at the state’s average residential rate of 13.37¢ per kWh (August 2026). A full charge from empty runs about $12.02.
Idaho ranks #47 of 51 for electricity prices (1 = most expensive), so this is below the U.S. average of $50 per 1,000 miles for the same car. A 30-mpg gas car would spend about $144 on fuel for those 1,000 miles at Idaho’s $4.33 a gallon, so home charging saves roughly $108 every 1,000 miles.
