EIA withholds or delays some monthly figures. For Connecticut and Florida and Kansas and Louisiana and New Hampshire and Ohio and West Virginia, the latest published month is earlier than July 2026, and the table uses it.
Why the summer price is misleading
EIA's monthly residential price is what customers paid divided by how much gas they used. In winter, homes burn a lot of gas, so the fixed charges on the bill are spread over many therms. In summer, many homes use gas only for hot water and cooking, the same fixed charges are spread over a few therms, and the price per unit jumps. Nothing about the gas itself changed.
The chart shows that pattern: peaks every summer and lows every winter. For anything to do with heating, the winter price is the one that matters, which is why the table and the calculators on this site use the November to March average.
Therms, Ccf and Mcf
Gas utilities bill in different units. Some bill by volume, in hundreds of cubic feet (Ccf) or thousands (Mcf); others convert the volume to therms, a unit of heat equal to 100,000 Btu. EIA reports prices per Mcf. To convert, this page uses EIA's measured heat content of the gas delivered in each state, which last winter averaged 1,038 Btu per cubic foot nationally. At that heat content, one Mcf holds about 10.38 therms, and one Ccf about 1.038.
To compare your own bill with these averages, add up the total charges for a winter month and divide by the therms (or Ccf) used. Delivery charges, the gas supply charge and taxes all belong in the total: they are part of what each unit of heat costs you.
What sets the price
The gas itself is only part of a residential bill. The rest pays for the pipes that bring it to the street and into the house, the utility's operating costs and its return, and state and local taxes. The commodity part follows wholesale markets and can swing a lot from one winter to the next; the delivery part changes when a state commission approves new rates. That is why two neighboring states buying gas from the same pipelines can still have very different prices per therm.
Gas is usually the cheapest way to heat a home where it is available, but not everywhere and not against every alternative. The heating fuel cost comparison puts gas next to electricity, propane and heating oil at your state's prices, and the heat pump vs. gas furnace calculator works out a full winter from your own gas use. If you heat with oil or propane instead, see heating oil and propane prices by state.
Questions people ask
How many therms does a home use in a winter?
It varies widely with climate, the size and insulation of the house, and the thermostat. The number on your own bills is the one that matters; the heat pump calculator starts from it.
Why is my price per therm higher than the table?
Your utility may charge more than the state average, or the month you checked had low use, which spreads the fixed monthly charge over fewer therms. Compare a winter month for the fairest picture.
