Model
Lg WM6998H*A
Rank #94 means 93 of the 615 clothes dryer models we track cost less to run each year; the 84th efficiency percentile means it uses less energy for its size than 84% of those models.
What does the Lg WM6998H*A cost to run per year?
At $71 a year to run, the Lg WM6998H*A is among the cheapest clothes dryer models we track, ranking #94 of 615. Efficiency-wise, once capacity is accounted for, it beats 84% of the class, a solidly strong result rather than a size-driven fluke. Its CEF of 6.3 reflects combined energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Aeg DC240-1 at $59/yr runs a little cheaper and the Premium Levella PHD457HB at $81/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 WM6998H*A's $71/yr adds up to roughly $923 in electricity alone, before purchase price or repairs.
By the numbers
The Lg WM6998H*A 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 $71/yr, here is what the Lg WM6998H*A 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 WM6998H*A costs about $710. That is roughly $420 less than the class median, which would run closer to $1130 over the same ten years.
How the Lg WM6998H*A compares
The clothes dryer class we track runs from $23 to $128 a year. At $71/yr, it runs about $42 a year cheaper than the class median of $113, and it is about $48 a year more than the cheapest clothes dryer to run at $23.
What drives its running cost
At 5 cu ft, the Lg WM6998H*A 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. The CEF of 6.3 on this model, above the class median of 3.93, measures combined energy factor; it is the number to compare directly against another model's CEF if capacity is similar.
- 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 WM6998H*A cheap to run?
Yes, relatively. At $71 a year it ranks #94 of 615 clothes dryer models we track, in the cheaper part of its class to run.
How much does the Lg WM6998H*A cost per month?
Roughly $5.88/mo, spreading the $71/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 380 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $71 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg WM6998H*A for its size?
84th 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.
