Why this number

At EIA’s national forecast prices for October 2026–March 2027 ($5.30/gal; 18.23¢/kWh at COP 2.17), a cold-climate heat pump is cheaper: $24.62 per million Btu delivered against $45.02 — a 45% gap. State prices change the answer: of the 29 states with published EIA figures for both, heating oil was cheaper in 6 and a cold-climate heat pump in 23 last winter, with the widest heating oil advantage in Maine ($31.65 vs $40.26) and the widest a cold-climate heat pump advantage in North Dakota ($15.81 vs $30.00). The calculator below uses your own prices and shows the break-even.

Oil and heat pump are priced in different units, so the only comparison that means anything for this pair is dollars per million Btu delivered — price per unit, converted to heat content, divided by appliance efficiency. For heating oil against a cold-climate heat pump that is $45.02 against $24.62 at EIA’s national outlook, then every state’s own published prices below, then yours in the calculator.

The break-even rule

A heat pump beats oil whenever COP > 2.9307 × ¢/kWh × oil AFUE ÷ (oil $/gal ÷ 1.385 × 100) — or, turned around, while electricity stays below oil $/MMBtu × COP ÷ 2.9307 cents. At $5.30/gal and 85% AFUE ($45.02/MMBtu), a COP-2.17 heat pump wins up to 33.3¢/kWh and even a COP-1.9 cold-snap rating wins up to 29.2¢.

National picture: last winter measured, this winter forecast

Oil versus heat pump: national cost per MMBtu delivered, last winter measured and this winter forecast
Option Last winter (EIA national average, Oct 2025–Mar 2026) This winter (EIA STEO September 2026 forecast)
Heating oil boiler (85% AFUE) $33.47/MMBtu $45.02/MMBtu ($5.30/gal)
Heat pump at 17°F (COP 2.17, NEEP median 3-ton ducted) $24.00/MMBtu $24.62/MMBtu (18.23¢/kWh at COP 2.17)

Heating oil is the fuel EIA moves most this winter: +35% nationally on a Brent path near $90.9 for 2026 against $69.1 in 2025. Electricity is forecast +3%.

Oil vs heat pump by state, last winter

Heating oil at the state’s SHOPP season average through an 85% AFUE boiler (regional where marked); a heat pump at the state’s winter-average electricity price and COP 2.17, the NEEP median for the 3-ton ducted class at 17°F. States with no published EIA price for one of the two are left out rather than filled from a national number. Sorted from the widest heating oil advantage to the widest a cold-climate heat pump advantage.

Reading the heating oil-vs-a cold-climate heat pump table honestly

Three things this column cannot see for heating oil against a cold-climate heat pump. The fixed monthly customer charge does not change the $45.02-vs-$24.62 per-unit answer, but it disappears entirely if you drop one of these fuels. Equipment is outside it: nothing here prices a new heating oil boiler or heat pump at 17°f, and there is no federal credit for either in 2026. And temperature: the heat pump row is its 17°F rating (COP 2.17); at 5°F the NEEP median is 1.9 ($28.12/MMBtu) and at 47°F 3.2 ($16.70), so a cold-climate heat pump moves through the season while heating oil does not — the crossover tool finds the switch point.

Weighing the whole season rather than the unit price? The heat pump vs furnace calculator starts from your annual heating spend, and the winter heating hub puts all five options on one national table.

Frequently asked questions

Is a heat pump cheaper than oil heat?

Yes — at EIA’s national outlook a heat pump costs $24.62 per MMBtu delivered against $45.02 for oil; last winter heating oil was cheaper in 6 of the 29 states with published prices, so your own two prices decide it.

Is heating oil cheaper than a cold-climate heat pump for heating?

At EIA’s national outlook prices for this winter, a cold-climate heat pump is cheaper: $24.62 against $45.02 per million Btu delivered. Last winter’s state averages split 6 states for heating oil and 23 for a cold-climate heat pump, so the honest answer depends on the two prices on your own bills, which the calculator takes directly. The comparison is per unit of delivered heat and ignores the fixed monthly customer charge and equipment cost.

What efficiencies does this comparison assume?

Heating oil at the state’s SHOPP season average through an 85% AFUE boiler (regional where marked); a heat pump at the state’s winter-average electricity price and COP 2.17, the NEEP median for the 3-ton ducted class at 17°F. For heating oil against a cold-climate heat pump every efficiency is editable, and an 80% atmospheric furnace against a 97% condensing one moves this pair’s answer more than a year’s price change.

Why do the state figures use last winter rather than a forecast?

Because heating oil and a cold-climate heat pump state prices are published by EIA only after the fact (SHOPP runs October to March; the Natural Gas Monthly lags two months) and no agency forecasts them by state. The September 2026 STEO moves the national heating oil price by +35% and a cold-climate heat pump by +3%; the calculator’s ’this winter’ preset applies those two changes.

Does a tax credit change the heating oil vs a cold-climate heat pump answer?

Not in 2026. The §25C credit for heat pumps, furnaces and boilers ended for property placed in service after 31 December 2025, so nothing installed for this winter qualifies federally. State and utility rebates continue and are listed on DSIRE. This page is a running-cost comparison, not tax advice.

How we calculated this

Worked for heating oil vs a cold-climate heat pump at EIA’s outlook: oil 10 × ($5.30/gal ÷ 1.385) ÷ 0.85 = $45.02/MMBtu; heat pump 293.07 × 0.1823 $/kWh ÷ 2.17 = $24.62/MMBtu. State rows use each state’s October–March EIA average through the same conversions.
