Model
Lg DLEX7480*E
Rank #179 means 178 of the 615 clothes dryer models we track cost less to run each year; the 37th efficiency percentile means it uses less energy for its size than 37% of those models.
What does the Lg DLEX7480*E cost to run per year?
At $113 a year to run, the Lg DLEX7480*E runs cheaper than most models in its class, ranking #179 of 615 clothes dryer models we track. Its 37th size-adjusted efficiency percentile is a step behind the class median, though not among the weakest results. The CEF figure of 3.94 on this model captures combined energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Lg DLEX4080* at $113/yr runs a little cheaper and the Lg DLEX6700* 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 Lg DLEX7480*E's $113/yr adds up to roughly $1469 in electricity alone, before purchase price or repairs.
Also sold as: Lg DLE6100*.
By the numbers
The Lg DLEX7480*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 $113/yr, here is what the Lg DLEX7480*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 DLEX7480*E costs about $1130. That is roughly $0 less than the class median, which would run closer to $1130 over the same ten years.
How the Lg DLEX7480*E compares
The clothes dryer class we track runs from $23 to $128 a year. At $113/yr, it sits right on the class median of $113, and it is about $90 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 7.3 cu ft, the Lg DLEX7480*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 3.94, above 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 DLEX7480*E cheap to run?
Yes, relatively. At $113 a year it ranks #179 of 615 clothes dryer models we track, in the cheaper part of its class to run.
How much does the Lg DLEX7480*E cost per month?
Roughly $9.39/mo, spreading the $113/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 607 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $113 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg DLEX7480*E for its size?
37th percentile once size is factored in, a fairly typical result for the class.
