How Idaho compares
Ranked by yearly saving, Idaho is 6th of 51. Savings run from $66 in Hawaii to $1,276 in Louisiana. The saving here is $157 more than the $1,084 a driver saves at the U.S. average price.
Gas would have to fall below $1.43 a gallon, from $4.33 now, before charging an EV in Idaho stopped saving money.
Public chargers averaged $0.42/kWh nationally on October 16, 2026, 3.1 times the home price here, so every mile charged in public cuts the saving. Charging only at home would raise it to $1,333 a year.
Two of its six neighbors save more: Nevada and Utah, led by Nevada at $1,274.
