What does the Whirlpool WED8740D*+ cost to run per year?
At $113 a year to run, the Whirlpool WED8740D*+ sits close to the middle of its class on cost, ranking #347 of 615 clothes dryer models we track. Once capacity is factored in, its efficiency percentile of 32 is below the class median, worth weighing alongside the raw dollar figure. At a CEF of 3.93, its combined energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Whirlpool WED81HED*+ at $113/yr runs a little cheaper and the Whirlpool WED87HED*+ at $113/yr runs a little more, a sense of how tightly models are packed at this point in the ranking.

What drives its running cost
At 7.3 cu ft, the Whirlpool WED8740D*+ is a small clothes dryer for its class, which spans 3.8 to 9.2 cu ft with a median of 7.4 cu ft, and smaller clothes dryer models generally cost less to run for the same job, all else being equal. Its CEF of 3.93, above the class median of 3.93, reflects combined energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- Heat source and Combined Energy Factor (CEF). CEF combines drying performance with standby and off-mode energy use; for a given drum size, a higher CEF means less energy per pound of laundry dried, and heat-pump models usually post the highest figures in the class.
- Drum capacity. Drum capacity sets how much laundry one cycle can hold, and heating a bigger volume of air generally costs more energy per cycle.
