Cost to Heat a Home in Massachusetts: Oil vs Gas vs Heat Pump

In Massachusetts the cheapest heat last winter was natural gas at $25.37 per MMBtu delivered; electric resistance cost $90.50 — EIA prices, October 2025 to March 2026.

Massachusetts heating cost per MMBtu, fuel by fuel

The season column is an illustrative 60 MMBtu of delivered heat; in Massachusetts that puts natural gas at $1,522 and electric resistance at $5,430 for the winter. The this-winter column applies EIA’s national STEO change per fuel to Massachusetts’s own price (oil +35% is the large one) — direction, not a state forecast.

The prices behind the table

Massachusetts’s June gas figure ($30.66/Mcf) runs 1.2× its winter average ($24.98) because EIA’s residential price is average revenue per Mcf with the fixed charge folded in; the high-volume winter months are the closest published proxy for the marginal rate this page needs.

What Massachusetts’s utilities charge

The statewide 30.88¢ hides a 8.0¢ spread between Massachusetts’s largest utilities, worth $23.45 per MMBtu on resistance heat and $10.80 on a heat pump. The ZIP lookup finds yours.

How Massachusetts homes are heated

Natural gas heats 51.7% of Massachusetts’s 2,762,070 occupied homes against 46.8% nationally, with electricity at 17.9%, propane at 4.4% and heating oil at 23.2%. That lines up with the table above: natural gas was also Massachusetts’s cheapest heat last winter at $25.37 per MMBtu.

What the numbers say about Massachusetts

At last winter’s average prices, the cheapest way to heat a home in Massachusetts was natural gas at about $25 per million Btu delivered, and the most expensive was electric resistance at $91 — a 3.6× spread between the two columns. Gas beat a cold-climate heat pump at 17°F (COP 2.17) by $16.34/MMBtu, and at 47°F (COP 3.2, $28.28) the heat pump still trails. At Massachusetts’s winter rates the economic balance point lands above 47°F (COP 3.57 needed against 3.20 available), so the furnace is cheaper at every rated temperature. Heating oil averaged $4.12/gal across 26 SHOPP survey weeks and finished the season at $5.74 on March 30, 2026; EIA’s September outlook puts national oil +35% for this winter, which would carry Massachusetts’s figure to roughly $47/MMBtu. Propane averaged $3.41/gal in the state survey, with a national -5% outlook for this winter.

Heating degree-days: Massachusetts’s own figure and the EIA division forecast

Massachusetts itself logged 5,451 population-weighted heating degree-days from October 2025 to March 2026 (NOAA Climate Prediction Center state series, base 65°F), against 3,500 for the contiguous US. The month-by-month table below is a different, coarser series — EIA STEO New England census division degree-days, the only one with a forecast for the coming winter; it groups Massachusetts with its neighbours and is not a Massachusetts figure:

January in the EIA New England census division (the coarse series that groups Massachusetts with its neighbours) averaged about 23°F last winter (65°F minus degree-days per day) and is forecast at 29°F for January 2027, a season move of -633 degree-days. Degree-days set how much heat Massachusetts needs, the table above sets the price per unit, and the bill jump calculator multiplies the two.

Heating oil prices in Massachusetts

EIA’s weekly SHOPP survey priced residential No. 2 heating oil in Massachusetts at $3.55/gal in the first October week of the 2025-26 season and $5.74 in the final March week — a season average of $4.12, low $3.55, high $5.77, against a national average of $4.01. The survey resumes in October 2026; the weekly tracker carries every state.

Where the heat pump crosses over in Massachusetts

At last winter’s averages of 30.88¢/kWh and $2.41/therm, a heat pump beats a 95% gas furnace whenever its COP exceeds 3.57. Massachusetts’s economic balance point on the NEEP median curve is above 47°F (COP 3.57 needed against 3.20 available), so the furnace is cheaper at every rated temperature; the crossover tool runs seven named units at Massachusetts’s prices and the dual-fuel calculator turns the answer into a changeover setting.

From October 6 the EIA Winter Fuels Outlook adds household expenditure by region and the weekly SHOPP survey restarts, giving Massachusetts fresh state propane and heating-oil readings on the weekly tracker .
