Model
Lg WKEX200H*A
Rank #139 means 138 of the 388 washing machine models we track cost less to run each year; the 67th efficiency percentile means it uses less energy for its size than 67% of those models.
What does the Lg WKEX200H*A cost to run per year?
The Lg WKEX200H*A costs about $19 a year to run, which beats most of the 388 washing machine models we track; it ranks #139. Efficiency-wise, once size is accounted for, it edges out 67% of the class, a modestly above-average showing. Its IMEF of 2.92 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Lg WKE100H*A at $19/yr runs a little cheaper and the Lg WKG101H*A at $19/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 WKEX200H*A's $19/yr adds up to roughly $190 in electricity alone, before purchase price or repairs.
Also sold as: Lg WM3580C*.
By the numbers
The Lg WKEX200H*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 $19/yr, here is what the Lg WKEX200H*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 WKEX200H*A costs about $190. That is roughly $10 less than the class median, which would run closer to $200 over the same ten years.
How the Lg WKEX200H*A compares
The washing machine class we track runs from $7 to $58 a year. At $19/yr, it runs about $1 a year cheaper than the class median of $20, and it is about $12 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.5 cu ft, the Lg WKEX200H*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). IMEF is this class's core efficiency yardstick; two washers with the same drum size can carry meaningfully different IMEF figures and running costs.
- Drum volume. A larger-capacity washer can wash more per load, which can lower cost per pound of laundry, but it also draws more water and energy per cycle if you are not filling it.
- Water heating. Most washers rely on your home's hot water supply, but internal-heater sanitize or hot-wash cycles use meaningfully more electricity than a cold or warm wash.
Common questions
Is the Lg WKEX200H*A cheap to run?
Yes. Its $19/yr running cost puts it at rank #139 of 388, below what most washing machine models we track cost to run.
How much does the Lg WKEX200H*A cost per month?
About $1.62 a month, which is the $19 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: 105 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $19 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg WKEX200H*A for its size?
67th percentile once size is factored in, a fairly typical result for the class.
