The EPA gives one yearly figure for gas dryers: 687 kWh equivalent, which combines the gas burned and the electricity for the drum and controls. We convert it to therms (1 kWh = 3,412 Btu; 1 therm = 100,000 Btu), so 687 kWh-eq is 23.4 therms, and price it at $1.48 per therm, the U.S. average residential gas price for 2025 (EIA). The EPA does not split out the electric part, so your real cost may be a few dollars higher.
