Model
Lg DLG8401*E
Rank #500 means 499 of the 615 clothes dryer models we track cost less to run each year; the 6th efficiency percentile means it uses less energy for its size than 6% of those models.
What does the Lg DLG8401*E cost to run per year?
At $127 a year to run, the Lg DLG8401*E is among the more expensive clothes dryer models we track to run, ranking #500 of 615. Its 6th size-adjusted efficiency percentile is well below the class median, worth weighing against the raw cost figure above. At a CEF of 3.49, 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 Lg SWWG50*4 at $127/yr runs a little cheaper and the Lg DLGX8601*E at $127/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 Lg DLG8401*E's $127/yr adds up to roughly $1651 in electricity alone, before purchase price or repairs.
Also sold as: Lg DLG6101*.
By the numbers
The Lg DLG8401*E 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 $127/yr, here is what the Lg DLG8401*E adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Lg DLG8401*E costs about $1270. That is roughly $140 more than the class median, which would run closer to $1130 over the same ten years.
How the Lg DLG8401*E compares
The clothes dryer class we track runs from $23 to $128 a year. At $127/yr, it runs about $14 a year above the class median of $113, and it is about $104 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 7.3 cu ft, the Lg DLG8401*E 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, and smaller clothes dryer models generally cost less to run for the same job, all else being equal. Its CEF of 3.49, 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 Lg DLG8401*E cheap to run?
Not especially. At $127 a year it ranks #500 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 Lg DLG8401*E cost per month?
Roughly $10.59/mo, spreading the $127/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 685 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $127 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg DLG8401*E for its size?
6th 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.
