Why this number

In Maryland, the cheapest heat last winter was natural gas at about $17.79 per million Btu delivered, then a cold-climate heat pump at $28.39 and heating oil at $34.36; electric resistance was the most expensive at $61.60 (EIA average prices, October 2025–March 2026, converted with the site’s standard efficiencies). For this winter EIA’s September outlook moves national heating oil +35%, natural gas -10%, propane -5% and electricity +3%; applied to Maryland’s own prices, natural gas stays cheapest at about $16.06. The calculator below ranks every option from the prices on your bills.

Maryland paid 21.02¢/kWh for electricity last winter — 26 of 35 on this list of 35 cold-weather states — and $1.69 per therm for gas (28 of 35); propane ran $3.58/gal (31 of 35) and heating oil $4.04/gal (30 of 35). Put on one basis, dollars per million Btu delivered, natural gas was the cheapest heat at $17.79 and electric resistance the dearest at $61.60 — a 44-dollar gap per MMBtu, or about $2,629 over a 60-MMBtu season.

Price basis: Maryland’s fuel prices are last winter’s measured EIA and SHOPP averages; the this-winter column scales each by EIA’s national STEO change for that fuel — a labelled estimate, not a state forecast.

Electric resistance (COP 1.00) $61.60 $3,696 $63.20 (+3%)

The season column is an illustrative 60 MMBtu of delivered heat; in Maryland that puts natural gas at $1,067 and electric resistance at $3,696 for the winter. The this-winter column applies EIA’s national STEO change per fuel to Maryland’s own price (oil +35% is the large one) — direction, not a state forecast.

The prices behind the table

Maryland fuel and electricity prices behind the comparison, with source, basis and vintage
Price Last winter average (Oct 2025–Mar 2026) Latest published reading Source and basis
Electricity 21.02¢/kWh 21.41¢/kWh (July 2026) EIA Electric Power Monthly 5.6.A; winter average from the monthly editions
Natural gas $1.69/therm ($17.51/Mcf, 5 of 6 months reported) $22.57/Mcf (June 2026, shoulder-season price) EIA Natural Gas Monthly, residential price by state; 1 Mcf = 10.38 therms
Heating oil $4.04/gal $5.28/gal (week of 2026-03-30) EIA SHOPP weekly survey, Maryland, Oct 2025–Mar 2026 average
Propane $3.58/gal $3.74/gal (week of 2026-03-30) EIA SHOPP weekly survey, Maryland, Oct 2025–Mar 2026 average

Maryland’s June gas figure ($22.57/Mcf) runs 1.3× its winter average ($17.51) 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 Maryland’s utilities charge

Maryland's largest electric utilities and what resistance and heat-pump heat cost at each one's average price
Utility (largest by customers) Residential customers ¢/kWh (EIA-861 2024) Resistance $/MMBtu Heat pump at 17°F $/MMBtu
Baltimore Gas & Electric Co 1,214,100 16.1¢ $47.18 $21.74
Potomac Electric Power Co 553,607 18.7¢ $54.80 $25.26
The Potomac Edison Company 256,568 13.3¢ $38.98 $17.96

The statewide 21.02¢ hides a 5.4¢ spread between Maryland’s largest utilities, worth $15.83 per MMBtu on resistance heat and $7.29 on a heat pump. The ZIP lookup finds yours.

How Maryland homes are heated

Propane (bottled, tank or LP gas) 3.7% 4.9%
Heating oil or kerosene 7.0% 4.1%
Wood 1.0% 1.4%

Electricity heats 43.5% of Maryland’s 2,339,510 occupied homes against 40.8% nationally, with electricity at 43.5%, propane at 3.7% and heating oil at 7.0%. The table above says otherwise for last winter: the households on electricity paid about $61.60 per MMBtu while natural gas delivered the same heat for $17.79, a $43.81 gap on every million Btu.

What the numbers say about Maryland

At last winter’s average prices, the cheapest way to heat a home in Maryland was natural gas at about $18 per million Btu delivered, and the most expensive was electric resistance at $62 — a 3.5× spread between the two columns. Gas beat a cold-climate heat pump at 17°F (COP 2.17) by $10.60/MMBtu, and at 47°F (COP 3.2, $19.25) the heat pump still trails. At Maryland’s winter rates the economic balance point lands above 47°F (COP 3.46 needed against 3.20 available), so the furnace is cheaper at every rated temperature. Heating oil averaged $4.04/gal across 26 SHOPP survey weeks and finished the season at $5.28 on March 30, 2026; EIA’s September outlook puts national oil +35% for this winter, which would carry Maryland’s figure to roughly $46/MMBtu. Propane averaged $3.58/gal in the state survey, with a national -5% outlook for this winter.

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

Maryland itself logged 4,234 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 South Atlantic census division degree-days, the only one with a forecast for the coming winter; it groups Maryland with its neighbours and is not a Maryland figure:

EIA STEO South Atlantic census division heating degree-days (not a state figure): last winter actual and this winter forecast, month by month

Mar 2026 220 Mar 2027 315
Oct–Mar total 2,326 Oct–Mar total 2,134

January in the EIA South Atlantic census division (the coarse series that groups Maryland with its neighbours) averaged about 45°F last winter (65°F minus degree-days per day) and is forecast at 48°F for January 2027, a season move of -192 degree-days. Degree-days set how much heat Maryland needs, the table above sets the price per unit, and the bill jump calculator multiplies the two.

Heating oil prices in Maryland

EIA’s weekly SHOPP survey priced residential No. 2 heating oil in Maryland at $3.77/gal in the first October week of the 2025-26 season and $5.28 in the final March week — a season average of $4.04, low $3.59, high $5.38, 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 Maryland

At last winter’s averages of 21.02¢/kWh and $1.69/therm, a heat pump beats a 95% gas furnace whenever its COP exceeds 3.46. Maryland’s economic balance point on the NEEP median curve is above 47°F (COP 3.46 needed against 3.20 available), so the furnace is cheaper at every rated temperature; the crossover tool runs seven named units at Maryland’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 Maryland fresh state propane and heating-oil readings on the weekly tracker .

Frequently asked questions

What is the cheapest way to heat a home in Maryland?

On last winter’s EIA average prices, natural gas at about $17.79 per million Btu delivered, against a cold-climate heat pump at $28.39 and heating oil at $34.36. Maryland’s ranking uses a 95% gas furnace, 92% propane furnace, 85% oil boiler and a heat pump at COP 2.17; it is per unit of heat, so Maryland’s fixed monthly charges and equipment prices sit outside it.

Is a heat pump cheaper than gas in Maryland?

At Maryland’s last-winter averages of 21.02¢/kWh and $1.69/therm, a heat pump needs a COP above 3.46 to beat a 95% furnace. Against Maryland’s required COP 3.46, the NEEP medians (3.20/2.17/1.90 at 47/17/5°F) mean the heat pump loses at every rating point in Maryland; the balance point is above 47°F (COP 3.46 needed against 3.20 available), so the furnace is cheaper at every rated temperature.

How much will heating oil and propane cost in Maryland this winter?

Nobody publishes a Maryland forecast; applying EIA’s September STEO national changes (+35% oil, -5% propane) to Maryland’s last-winter $4.04 and $3.58 per gallon gives roughly $5.44 and $3.42 — the ’this winter’ column. Maryland’s weekly SHOPP readings resume in October; the Winter Fuels Outlook (October 6) adds household expenditure on top.

Where do the Maryland prices on this page come from?

21.02¢/kWh is the EIA Electric Power Monthly average for Maryland over the October 2025–March 2026 editions (21.41¢ in July 2026); the share of homes on each heating fuel is Census ACS 2019–2023 5-year table B25040; $17.51/Mcf is the Natural Gas Monthly winter average (5 months), converted at 10.38 therms per Mcf; oil $4.04 and propane $3.58 per gallon are SHOPP state season averages; degree-days are the STEO South Atlantic series. Only the ’this winter’ column is an estimate.

How we calculated this

Worked for Maryland at last winter’s averages: gas 10 × $1.69 ÷ 0.95 = $17.79/MMBtu; propane 10 × ($3.58 ÷ 0.91452) ÷ 0.92 = $42.61; oil 10 × ($4.04 ÷ 1.385) ÷ 0.85 = $34.36; resistance 293.07 × 0.2102 = $61.60; heat pump $61.60 ÷ 2.17 = $28.39. The this-winter column multiplies each by EIA’s national STEO change for that fuel (electricity ×1.026, gas ×0.903, propane ×0.953, oil ×1.345).
