$98

At Iowa’s average winter price of $0.98 a therm, delivery and fixed charges included. Your utility’s rate may differ.

Why the price per Mcf jumps in summer

EIA’s residential price is total revenue divided by gas delivered. Utilities charge a fixed monthly customer fee, so in summer, when households burn little gas, that fee is spread over a small volume and the price per Mcf looks high ($24.48 in August 2026). The winter price, $10.14 per Mcf for Nov 2025 – Mar 2026, is closer to what each extra unit of heat costs.

Gas or a heat pump in Iowa?

At last winter’s gas price and this year’s electricity rate (14.6¢ per kWh), heat from a 90%-efficient gas furnace costs $10.88 per million Btu and from a heat pump with a seasonal COP of 2.5 about $17.06. Gas is the cheaper heat here at current prices. Compare every fuel in Iowa.
