Gas use includes heating, water heating, cooking and drying. Customer counts are 2024, the latest EIA year; a growing customer base makes the newest bills slightly overstated. States are ranked by bill.
Average heating bill: winter vs summer
Gas bills follow the weather. The average U.S. gas customer used about 137 therms in Jan '26 but only a small fraction of that in summer, when gas heats water and cooks.[ngcons][ngcust] The estimated average bill moved from about $37.67 in Sep '25 to $184.47 in Jan '26; the yearly average of $85.27 sits between.
So the average heating bill in a cold month is several times the summer bill. Budget plans that spread the year evenly bill close to the 12-month average.
How many therms does a house use?
A U.S. gas customer used 54 therms a month, or about 648 a year, over Sep 2025–Aug 2026. Use per customer is highest in Alaska (133 therms a month), New York (87) and Michigan (84), and lowest in Florida (15) and New Mexico (16).[ngcons][ngcust][ngheat] The biggest drivers are heating degree days, house size and furnace efficiency. If your meter reads in CCF or MCF, convert it with CCF to therms before comparing.
Lowering a gas bill
- Price. Compare your bill's all-in price per therm with your state's average in the natural gas prices table. If your state allows gas supply choice, the supplier's price replaces only the supply part; the utility still charges delivery.
- Efficiency. An old 80% AFUE furnace burns about 19% more gas than a 95% model for the same heat (0.95 ÷ 0.80 = 1.19).
- Switching fuel. At $1.58 per therm, gas usually beats propane and oil; whether a heat pump beats gas depends on your electricity rate, which the heat pump vs furnace cost calculator checks.
