Model
Lg WKHC252H*A
Rank #87 means 86 of the 388 washing machine models we track cost less to run each year; the 88th efficiency percentile means it uses less energy for its size than 88% of those models.
What does the Lg WKHC252H*A cost to run per year?
The Lg WKHC252H*A is a relatively cheap runner for its class: about $18 a year, rank #87 of 388. Efficiency-wise, once capacity is accounted for, it beats 88% of the class, a solidly strong result rather than a size-driven fluke. At a IMEF of 2.92, its integrated modified energy factor is the single figure that best explains how it earns its running-cost number.
Immediately around it on the leaderboard, the Lg WKGX301H*A at $18/yr runs a little cheaper and the Lg WM5800H*A at $18/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A washing machine typically stays in service for somewhere around 10 years; over that span, the Lg WKHC252H*A's $18/yr adds up to roughly $180 in electricity alone, before purchase price or repairs.
Also sold as: Lg SWWE50*3.
By the numbers
The Lg WKHC252H*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 $18/yr, here is what the Lg WKHC252H*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 WKHC252H*A costs about $180. That is roughly $20 less than the class median, which would run closer to $200 over the same ten years.
How the Lg WKHC252H*A compares
The washing machine class we track runs from $7 to $58 a year. At $18/yr, it runs about $2 a year cheaper than the class median of $20, and it is about $11 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5 cu ft, the Lg WKHC252H*A is a mid-size washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone. The IMEF of 2.92 on this model, above the class median of 2.76, measures integrated modified energy factor; it is the number to compare directly against another model's IMEF if capacity is similar.
- Spin and wash efficiency (IMEF). A higher Integrated Modified Energy Factor means the machine wrings more useful washing (and a drier spin) out of every kilowatt-hour and gallon it uses.
- Drum volume. Drum volume sets the ceiling on how much a single cycle can wash, and it is usually the first driver of a washer's per-cycle energy use.
- Water heating. Cycle temperature, more than drum size, is usually what separates a cheap wash cycle from an expensive one on models with an internal water heater.
Common questions
Is the Lg WKHC252H*A cheap to run?
Yes, relatively. At $18 a year it ranks #87 of 388 washing machine models we track, in the cheaper part of its class to run.
How much does the Lg WKHC252H*A cost per month?
Roughly $1.53/mo, spreading the $18/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 99 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $18 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg WKHC252H*A for its size?
88th percentile once size is factored in, a fairly typical result for the class.
