Model
Kenmore 405.9227##
Rank #600 means 599 of the 615 clothes dryer models we track cost less to run each year; the 31st efficiency percentile means it uses less energy for its size than 31% of those models.
What does the Kenmore 405.9227## cost to run per year?
The Kenmore 405.9227## costs about $128 a year to run, sitting in the very bottom slice of the cheapest-to-run leaderboard, rank #600 of 615. Once capacity is factored in, its efficiency percentile of 31 is below the class median, worth weighing alongside the raw dollar figure. The CEF figure of 3.48 on this model captures combined energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Whirlpool WGD6720R** at $128/yr runs a little cheaper and the Electrolux ELFG7626*** at $128/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 Kenmore 405.9227##'s $128/yr adds up to roughly $1664 in electricity alone, before purchase price or repairs.
By the numbers
The Kenmore 405.9227## 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 $128/yr, here is what the Kenmore 405.9227## adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Kenmore 405.9227## costs about $1280. That is roughly $150 more than the class median, which would run closer to $1130 over the same ten years.
How the Kenmore 405.9227## compares
The clothes dryer class we track runs from $23 to $128 a year. At $128/yr, it runs about $15 a year above the class median of $113, and it is about $105 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 8.1 cu ft, the Kenmore 405.9227## 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, and larger clothes dryer models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. The CEF of 3.48 on this model, below 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.
Common questions
Is the Kenmore 405.9227## cheap to run?
Not especially. At $128 a year it ranks #600 of 615 clothes dryer models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Kenmore 405.9227## cost per month?
Roughly $10.63/mo, spreading the $128/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 687 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $128 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Kenmore 405.9227## for its size?
31st percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
