Model
Lg DLEX6500*
Rank #150 means 149 of the 615 clothes dryer models we track cost less to run each year; the 62nd efficiency percentile means it uses less energy for its size than 62% of those models.
What does the Lg DLEX6500* cost to run per year?
Ranking #150 of 615, the Lg DLEX6500* is in the cheaper half of its class to run, at about $113 a year. Normalized for capacity, it beats 62% of clothes dryer models we track, a better-than-average efficiency result. 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 DLE3470* at $113/yr runs a little cheaper and the Lg DLE6100* 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 DLEX6500*'s $113/yr adds up to roughly $1469 in electricity alone, before purchase price or repairs.
Also sold as: Lg DLE3090*.
By the numbers
The Lg DLEX6500* 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 DLEX6500* 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 DLEX6500* 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 DLEX6500* 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 7.4 cu ft, the Lg DLEX6500* 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 DLEX6500* cheap to run?
Yes, relatively. At $113 a year it ranks #150 of 615 clothes dryer models we track, in the cheaper part of its class to run.
How much does the Lg DLEX6500* 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 DLEX6500* for its size?
62nd percentile once size is factored in, a fairly typical result for the class.
