Massachusetts EV vs gas · Gas October 12, 2026 · Electricity rates 2025
Yes. On the Massachusetts average home rate, charging an EV costs the same per mile as gas at $2.47 a gallon. Gas in the Boston area averaged $4.35 on October 12, 2026, so 1,000 miles a month costs about $91 to charge versus $161 in gas: roughly $70 a month back.
What you pay for power sets what charging costs. Here are the numbers for Boston.
Eversource delivers the power in Boston. Many homes buy the power itself through the city's Community Choice Electricity program or a supplier, so we use the Massachusetts average home rate here.
Average home rate 30.5 cents per kWh (Massachusetts average, EIA July 2026). Charging costs the same per mile as gas at $2.47 a gallon: about $91 for 1,000 miles versus $161 in gas.
Some suburbs are served by National Grid or a town-owned utility instead.
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 Boston, gas would have to fall below $2.47 a gallon.

We assume 1,000 miles a month, a typical new EV that uses 30 kWh per 100 miles, a 27 mpg gas car, and home charging at each utility's average residential rate, which includes its fixed monthly charges. An overnight or EV rate is often cheaper than that average, and public fast charging costs much more. Treat this as the honest average, not your bill.

Yes. Charging at home at the Massachusetts average rate (30.5 cents per kWh, Massachusetts average, EIA July 2026) costs about $91 per 1,000 miles. The same miles in a 27 mpg car cost about $161 at the $4.35 Boston gas average on October 12, 2026.
About $2.47 a gallon. That is what a 27 mpg car would need to pay to match the cost per mile of charging at home at the Massachusetts average rate.
At home, about $91 per 1,000 miles at the Massachusetts average rate (30.5 cents per kWh), for a typical EV that uses 30 kWh per 100 miles. Public fast charging costs much more per kWh than home charging, so these numbers assume you charge at home most of the time.
Massachusetts has state EV money open right now (see the Massachusetts guide), and utilities here add their own: Eversource: Wiring/panel upgrade rebate for a Level 2 smart charger, up to $700 ($1,700 income-eligible). Check the utility's page before you buy; programs fill up and change.
