Household budgets built around a home heating oil tank are about to run into a federal number nobody controls. The U.S. Energy Information Administration’s newest monthly market report projects how much more a gallon of heating oil delivered this winter will cost compared with the same three months a year earlier, and the gap is not a rounding error. It traces back to a supply problem the agency has been documenting since spring, concentrated in one part of the country.
Retail Heating Oil: $3.68 to $5.66 in the EIA’s Own Table
The EIA’s September 2026 Short-Term Energy Outlook lists retail heating oil, including taxes, at $3.68 a gallon in the fourth quarter of 2025 — the actual, already-recorded average from a year earlier — and forecasts it climbing to $5.66 a gallon this quarter, the fourth quarter of 2026 that covers most of the coming heating season. That works out to roughly a 54 percent increase over the same three months a year earlier. The same table forecasts the price easing to $4.94 a gallon in the first quarter of 2027, and puts full-year figures at $3.62 for 2025, $5.10 for 2026 and $4.31 for 2027, still elevated well past the point where the report expects the price to have peaked.
Heating oil and diesel fuel are both distillates, refined from the same barrel of crude, and the outlook’s diesel numbers moved in the same direction. Retail on-highway diesel is projected to rise from $3.70 a gallon in the fourth quarter of 2025 to $5.55 a gallon in the fourth quarter of 2026. Between its August and September releases, the EIA raised its own full-year 2026 diesel forecast from $4.85 to $5.07 a gallon, a sign that whatever is squeezing distillate supply got tighter over the summer rather than easing.
Relief that waits to be asked for: Property-tax freezes, exemptions and utility help are rarely applied automatically, and each has its own filing window. See the five kinds of relief in The Senior Property Tax & Home-Cost Relief Kit.
Why the EIA Points to Distillate Inventories and the Northeast
The agency’s own explanation centers on inventories, not only on crude oil prices moving around the Strait of Hormuz disruptions that dominate the rest of its report. In the same outlook, the EIA states that U.S. distillate fuel oil inventories are forecast to drop below 100 million barrels in September 2026 and stay below the five-year low through most of 2027, as U.S. refiners keep exporting distillate into a tight global market even as domestic supply tightens. Net exports of distillate, the agency notes, have run above or near the five-year high in every month of 2026 since February. That effect is expected to be especially pronounced this fall: distillate production typically drops during the industry’s fall refinery-maintenance season, just as harvest-season agricultural demand and the early weeks of home heating draw on the same barrels of fuel.
The report states plainly that “low inventories may also contribute to higher prices for residential heating oil in the Northeastern United States” — the same distillate squeeze that is also pushing up diesel prices nationwide. That regional detail matters because heating oil use is concentrated rather than spread evenly across the country.
The Households Already Paying to Heat With Oil
Heating oil is a shrinking but still significant fuel choice, and it is unusually regional. In the winter of 2023-2024, about 4.79 million U.S. households used heating oil as their primary heating fuel, and roughly 82 percent of those households sat inside the Northeast Census Region — the same part of the country the EIA’s September outlook names. For those households, the report’s retail heating oil line is not an abstract commodity price; it tracks closely with what a local dealer quotes to fill the tank.
Unlike natural gas or electric customers on a metered monthly bill, heating oil households typically pay for a large delivery at once, so a per-gallon increase lands as one larger charge rather than a gradually rising line item. A household that filled its tank at last winter’s average price and needs a comparable delivery this winter is looking at a bill roughly half again as large on a per-gallon basis, based on the EIA’s own quarterly comparison, before accounting for how much oil that particular home actually burns. The agency typically adds per-household consumption and total-season cost estimates to this same price line in a separate winter fuels report each October; the September outlook reviewed here covers the price forecast itself, not a household’s full seasonal total.
Cost Components Behind a Heating Oil Bill
The EIA’s own breakdown of a heating oil bill shows why a crude oil and distillate squeeze passes through so directly to the price at the tank. From the winter of 2012-13 through 2021-22, the most recent period for which the agency has published this breakdown of heating oil price components, the cost of crude oil made up 48 percent of the average retail price, distribution and marketing made up 37 percent, and refinery processing accounted for the remaining 15 percent. A rise in crude oil prices and a squeeze in distillate refining and exports both run through nearly half of that structure at the same time.
Federal assistance exists for households that cannot absorb an increase of that size: the Low Income Home Energy Assistance Program distributes federal funds to states to help cover winter heating bills, including for oil-heated homes, though its funding and eligibility rules do not move in step with any single winter’s price forecast. The EIA’s own guidance for heating oil customers notes that tanks filled in late summer or early fall, before the seasonal price climb captured in its own table, have historically cost less than tanks filled once cold weather sets in — a pattern the agency has tracked across multiple winters, not a one-time observation.
Before the Heating Season Starts
A heating oil bill that climbs by more than half in a single winter rarely arrives alone. Property tax bills, water and sewer rates, and other fixed home costs tend to come due in the same stretch of the calendar, and older homeowners on a fixed income absorb all of them from the same budget. Property-tax freezes, exemptions and utility relief programs exist in most states, but they almost never apply automatically.
