Cost to run a ventilating fan by state
A typical ENERGY STAR ventilating fan costs between $1.73 a year in Nevada and $6.42 in Hawaii, about 3.7 times as much. The median state is around $2.22.
“Typical” is the median annual energy use of 1,040 current ENERGY STAR certified ventilating fans (14 kWh a year) times each state’s average residential price from the U.S. EIA (August 2026). Your own rate and the exact model change the result; use the calculator on any ventilating fan page. For this product the yearly kWh is our estimate from ENERGY STAR’s listed power, assuming 2 hours a day at its rated airflow, every day of the year.
