Model
Whirlpool WED8700E**
Rank #255 means 254 of the 615 clothes dryer models we track cost less to run each year; the 87th efficiency percentile means it uses less energy for its size than 87% of those models.
What does the Whirlpool WED8700E** cost to run per year?
At about $113 a year, the Whirlpool WED8700E** lands in the middle third of clothes dryer models we track on running cost, rank #255 of 615. Few clothes dryer models we track beat it on size-adjusted efficiency; it edges out 87% of the class once capacity is normalized. Its CEF of 3.93 reflects combined energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Whirlpool WED8500D*+ at $113/yr runs a little cheaper and the Whirlpool WED72HED*+ 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 WED8700E**'s $113/yr adds up to roughly $1469 in electricity alone, before purchase price or repairs.
Also sold as: Kenmore C6813*41*.
By the numbers
The Whirlpool WED8700E** normalized against its whole class, so each figure means something.
What it costs you over time
Running cost is an every-year number, so it compounds. At $113/yr, here is what the Whirlpool WED8700E** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Whirlpool WED8700E** costs about $1130. That is roughly $0 less than the class median, which would run closer to $1130 over the same ten years.

What drives its running cost
At 8.8 cu ft, the Whirlpool WED8700E** is a large clothes dryer for its class, which spans 3.8 to 9.2 cu ft with a median of 7.4 cu ft, among clothes dryer models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. 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). Heat-pump dryers recycle heat instead of generating it fresh with a resistance coil, and typically use meaningfully less electricity per load than a conventional resistance dryer, at the cost of a longer cycle; CEF is the federal figure that captures this.
- Drum capacity. A larger drum can dry a bigger load per cycle, but it also usually needs more energy per cycle to heat the extra air volume.
Common questions
Is the Whirlpool WED8700E** cheap to run?
Roughly, yes. Its $113/yr figure is close to the class median, ranking #255 of 615, neither a bargain nor a splurge on running cost.
