Price × usage = bill, exactly: 30.44¢/kWh × 603 kWh ≈ $183. A state can land high on either factor — Massachusetts pays well above the national rate but uses less power than average.

Trend since 2008
Each point is a trailing 12-month average, which strips out the summer/winter swing and leaves the underlying trend. Bills start in January 2008 because that is when EIA began reporting customer counts.

Massachusetts electricity bills in context
The average monthly electricity bill in Massachusetts from June 2025 to May 2026 was $183, the fifth highest among the 50 states and DC. This bill is $28 above the national average of $155, or 18% higher. The gap comes from two opposing forces: Massachusetts residents pay 30.44¢/kWh, which is 12.60¢/kWh above the national rate of 17.84¢/kWh, but they use 603 kWh per month compared with the national average of 871 kWh, which pulls the bill down.
Over the past year, the average bill rose from $173 to $183, a 5.8% increase. Over the longer run, change has been steeper: since May 2021, the bill has climbed 36.9%, and since December 2008 it has risen 69%. Seasonal swings are pronounced. The bill peaked at $240 in July 2025 and reached its lowest point at $137 in May 2026, a swing of $103.
Among neighbouring states, only Connecticut at $203 carries a higher average monthly bill. New Hampshire at $167, Rhode Island at $165, and New York at $164 all fall below Massachusetts. Vermont stands notably lower at $140.

How this is calculated
EIA’s retail-sales dataset reports, for every state and month, total residential revenue and the number of residential customers served. The average monthly bill is simply the first divided by the second — total spending across all households, spread evenly over all accounts.
bill = revenue ÷ customers · averaged over 12 months (June 2025 – May 2026)
Two caveats worth knowing. It is an average, so it blends apartments with large houses — a typical household in Massachusetts may pay well above or below $183. And it counts what was actually billed for electricity, including fixed service charges, so it is not the same as multiplying your own usage by the advertised rate.
