Model
Lg WT7880H*A
Rank #315 means 314 of the 388 washing machine models we track cost less to run each year; the 52nd efficiency percentile means it uses less energy for its size than 52% of those models.
What does the Lg WT7880H*A cost to run per year?
Do the math and the Lg WT7880H*A's $28/yr puts it at rank #315 of 388, one of the costlier washing machine models we track to keep running. Normalized for capacity, it beats 52% of washing machine models we track, an average result for the class. At a IMEF of 2.76, 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 WT7800H*A at $28/yr runs a little cheaper and the Lg WT7900H*A at $28/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 WT7880H*A's $28/yr adds up to roughly $280 in electricity alone, before purchase price or repairs.
Also sold as: Lg WT7900H*A.
By the numbers
The Lg WT7880H*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 $28/yr, here is what the Lg WT7880H*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 WT7880H*A costs about $280. That is roughly $80 more than the class median, which would run closer to $200 over the same ten years.
How the Lg WT7880H*A compares
The washing machine class we track runs from $7 to $58 a year. At $28/yr, it runs about $8 a year above the class median of $20, and it is about $21 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5.5 cu ft, the Lg WT7880H*A is a large washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, among washing machine models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal. Beyond size, its IMEF of 2.76, above 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). 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 WT7880H*A cheap to run?
Not especially. At $28 a year it ranks #315 of 388 washing machine models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Lg WT7880H*A cost per month?
Roughly $2.32/mo, spreading the $28/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 150 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $28 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg WT7880H*A for its size?
52nd 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.
