Model
Lg WM1385H*
Rank #218 means 217 of the 388 washing machine models we track cost less to run each year; the 2nd efficiency percentile means it uses less energy for its size than 2% of those models.
What does the Lg WM1385H* cost to run per year?
The Lg WM1385H* costs about $22 a year to run, a fairly typical figure for the class; it ranks #218 of 388. Capacity-normalized, it ranks ahead of just 2% of washing machine models we track, near the bottom of every model we track in the class. At a IMEF of 2.07, 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 Miele WXR960 at $22/yr runs a little cheaper and the Lg WM1388H* at $22/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 WM1385H*'s $22/yr adds up to roughly $220 in electricity alone, before purchase price or repairs.
Also sold as: Lg WM1388H*, Lg WM1399H*A.
By the numbers
The Lg WM1385H* 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 $22/yr, here is what the Lg WM1385H* 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 WM1385H* costs about $220. That is roughly $20 more than the class median, which would run closer to $200 over the same ten years.
How the Lg WM1385H* compares
The washing machine class we track runs from $7 to $58 a year. At $22/yr, it runs about $2 a year above the class median of $20, and it is about $15 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.3 cu ft, the Lg WM1385H* is a small washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 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. Beyond size, its IMEF of 2.07, below the class median of 2.76, is the class's own efficiency yardstick, integrated modified energy factor, and it is what separates two similarly sized models with different running costs.
- 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 WM1385H* cheap to run?
Roughly, yes. Its $22/yr figure is close to the class median, ranking #218 of 388, neither a bargain nor a splurge on running cost.
How much does the Lg WM1385H* cost per month?
About $1.86 a month, which is the $22 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: 120 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $22 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Lg WM1385H* for its size?
2nd percentile once size is factored in, a fairly typical result for the class.
