Model
Lg DLE7050*
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 DLE7050* cost to run per year?
Among the 615 clothes dryer models we track, the Lg DLE7050* sits in the below-average-cost group, rank #179, at roughly $113 a year. Size-adjusted, this model trails most of its class on efficiency, ahead of just 37% of clothes dryer models we track. At a CEF of 3.94, 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 DLEX4370* at $113/yr runs a little cheaper and the Lg DLEX5005* 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 DLE7050*'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 DLE7050* 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 DLE7050* 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 DLE7050* 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 DLE7050* 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 DLE7050* 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. Beyond size, its CEF of 3.94, above the class median of 3.93, is the class's own efficiency yardstick, combined energy factor, and it is what separates two similarly sized models with different running costs.
- Heat source and Combined Energy Factor (CEF). Heat-pump dryers recycle heat instead of generating it fresh with a resistance coil, and typically use meaningfully less electricity per load than a conventional resistance dryer, at the cost of a longer cycle; CEF is the federal figure that captures this.
- Drum capacity. A larger drum can dry a bigger load per cycle, but it also usually needs more energy per cycle to heat the extra air volume.
Common questions
Is the Lg DLE7050* cheap to run?
Yes. Its $113/yr running cost puts it at rank #179 of 615, below what most clothes dryer models we track cost to run.
How much does the Lg DLE7050* cost per month?
About $9.39 a month, which is the $113 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 607 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $113 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg DLE7050* for its size?
37th percentile once size is factored in, a fairly typical result for the class.
