Model
Lg DLHX4372*
Rank #115 means 114 of the 615 clothes dryer models we track cost less to run each year; the 77th efficiency percentile means it uses less energy for its size than 77% of those models.
What does the Lg DLHX4372* cost to run per year?
Few clothes dryer models we track cost less to run than the Lg DLHX4372*: about $103 a year, rank #115 of 615. Normalized for capacity, it beats 77% of clothes dryer models we track, a better-than-average efficiency result. Its CEF of 4.3 reflects combined energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Whirlpool YWED99HED*+ at $99/yr runs a little cheaper and the Samsung DV52J870*E* 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 DLHX4372*'s $103/yr adds up to roughly $1339 in electricity alone, before purchase price or repairs.
By the numbers
The Lg DLHX4372* 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 $103/yr, here is what the Lg DLHX4372* 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 DLHX4372* costs about $1030. That is roughly $100 less than the class median, which would run closer to $1130 over the same ten years.
How the Lg DLHX4372* compares
The clothes dryer class we track runs from $23 to $128 a year. At $103/yr, it runs about $10 a year cheaper than the class median of $113, and it is about $80 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 7.3 cu ft, the Lg DLHX4372* 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 4.3, 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 DLHX4372* cheap to run?
Yes, relatively. At $103 a year it ranks #115 of 615 clothes dryer models we track, in the cheaper part of its class to run.
How much does the Lg DLHX4372* cost per month?
Roughly $8.6/mo, spreading the $103/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 556 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $103 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg DLHX4372* for its size?
77th percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
