A typical Massachusetts household pays

Nobody pays the average
Dearest — July 2025
$240
Cheapest — May 2026
$137
The dearest month costs $104 more than the cheapest — 76% higher and it is air conditioning that does it. Massachusetts runs about 700 cooling degree days a year, so the summer bill is where any efficiency gain shows up.
Why the bill is what it is
A bill is a rate multiplied by a quantity, and in Massachusetts the price per kilowatt hour is doing most of the work. Comparing your own bill to this figure only tells you something once you know which of the two you could actually change — the rate is largely fixed, the quantity is not.
Heating and cooling are usually the largest movable part. Whether that means a heat pump, a more efficient air conditioner, or neither depends on Massachusetts's prices rather than on general advice.
Figures are twelve-month averages across 2,867,016 residential accounts in Massachusetts, from the US Energy Information Administration. They describe the state, not your house — square footage, insulation and what you keep the thermostat at move an individual bill a long way. See the Massachusetts rate page for the underlying prices.
