Charging a 2026 Volkswagen ID.4 at home in Idaho

In Idaho, home electricity runs 12.8¢/kWh — put a 2026 Volkswagen ID.4's EPA-rated 29.8 kWh/100mi against that and 100 miles costs $3.81, versus $16.02 for a gas car averaging 25.5 mpg. That works out to 76.2% cheaper per mile than gasoline in Idaho — charging at home costs a fraction of what gas would here.

What a year of driving costs

Cost of a full charge

At Idaho's rate, fully covering this 2026 Volkswagen ID.4's 291-mile EPA range costs about $11.09 (86.7 kWh) — the energy the EPA test actually used, not the battery's rated size.
