Model
Whirlpool YWED7990FW*
Rank #107 means 106 of the 615 clothes dryer models we track cost less to run each year; the 86th efficiency percentile means it uses less energy for its size than 86% of those models.
What does the Whirlpool YWED7990FW* cost to run per year?
The Whirlpool YWED7990FW* costs about $99 a year to run and sits near the top of the cheapest-to-run leaderboard, rank #107 of 615. Efficiency-wise, once capacity is accounted for, it beats 86% of the class, a solidly strong result rather than a size-driven fluke. At a CEF of 4.5, 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 WED9290FW* at $99/yr runs a little cheaper and the Whirlpool YWED9290FC* at $99/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 YWED7990FW*'s $99/yr adds up to roughly $1287 in electricity alone, before purchase price or repairs.

What drives its running cost
At 7.4 cu ft, the Whirlpool YWED7990FW* 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, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. The CEF of 4.5 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.
