Model
Lg DLE3460*
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 DLE3460* cost to run per year?
The Lg DLE3460* is a relatively cheap runner for its class: about $113 a year, rank #150 of 615. Its 62th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. Its CEF of 3.94 reflects combined energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Lg DLEX7650*E at $113/yr runs a little cheaper and the Lg DLE7060*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 DLE3460*'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 DLE3460* 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 DLE3460* 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 DLE3460* 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 DLE3460* 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 DLE3460* 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, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. 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 DLE3460* 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 DLE3460* 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 DLE3460* for its size?
62nd percentile once size is factored in, a fairly typical result for the class.
