By city, utility by utility: Is an EV cheaper than gas in Boston?
Home electricity averages 30.5 cents per kWh (EIA, July 2026), 67% above the 18.3-cent national average. That makes Massachusetts the 48th cheapest of 51 places to charge at home (4th most expensive).
The rate is up 1.4% from a year ago (30.1 to 30.5 cents). At today's rate, 12,000 miles a year costs about $1,098 to charge at home, the same per mile as a gas car that gets 48 mpg.
Regular gas averages $4.35 a gallon (AAA, October 6, 2026), about the same as the $4.37 national average, the 31st cheapest of 51. A 27 mpg car burns about 444 gallons over 12,000 miles, roughly $1,934 a year.
Gas would have to fall to about $2.47 a gallon before that car costs less per mile than charging at home in Massachusetts.
Massachusetts does not charge EV owners an extra registration fee, so the full $836 a year in fuel savings at 12,000 miles stays yours.
Same 1,000 miles a month, same car, each state's own prices. Massachusetts saves $70 a month.
Gas prices jumped in 2026 when the war with Iran disrupted oil shipping through the Strait of Hormuz. Home electricity is priced by utilities under state regulators and moves far more slowly, so the gap tends to widen when gas spikes. For a 27 mpg car to cost less per mile than charging at home in Massachusetts, gas would have to fall below $2.47 a gallon.
