Model
Electrolux EFMG427****
Rank #524 means 523 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 Electrolux EFMG427**** cost to run per year?
Do the math and the Electrolux EFMG427****'s $128/yr puts it at rank #524 of 615, one of the costlier clothes dryer models we track to keep running. Normalized for capacity, it beats only 31% of clothes dryer models we track, a below-average efficiency result. 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 Ge GFD40GSM**** at $128/yr runs a little cheaper and the Electrolux EFMG527**** 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 Electrolux EFMG427****'s $128/yr adds up to roughly $1664 in electricity alone, before purchase price or repairs.

By the numbers
The Electrolux EFMG427**** 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 Electrolux EFMG427**** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Electrolux EFMG427**** 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 Electrolux EFMG427**** 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 cu ft, the Electrolux EFMG427**** 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. Its CEF of 3.48, below 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.
Common questions
Is the Electrolux EFMG427**** cheap to run?
Not especially. At $128 a year it ranks #524 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 Electrolux EFMG427**** 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 Electrolux EFMG427**** 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.
