What does the Whirlpool WED4720R** cost to run per year?

At $113 a year to run, the Whirlpool WED4720R** sits close to the middle of its class on cost, ranking #299 of 615 clothes dryer models we track. Once capacity is factored in, its efficiency percentile of 50 is fairly typical for the class, neither a standout nor a laggard. The CEF figure of 3.93 on this model captures combined energy factor, the main efficiency lever ENERGY STAR tracks for this class.

Immediately around it on the leaderboard, the Midea MLE52N7AWW at $113/yr runs a little cheaper and the Whirlpool YWED5220R** at $113/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A clothes dryer typically stays in service for somewhere around 13 years; over that span, the Whirlpool WED4720R**'s $113/yr adds up to roughly $1469 in electricity alone, before purchase price or repairs.

What drives its running cost

At 7.4 cu ft, the Whirlpool WED4720R** 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, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. The CEF of 3.93 on this model, above the class median of 3.93, measures combined energy factor; it is the number to compare directly against another model's CEF if capacity is similar.

  • 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.
