Model
Lg WT5680H*A
Rank #273 means 272 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 WT5680H*A cost to run per year?
Do the math and the Lg WT5680H*A's $25/yr puts it at rank #273 of 388, on the pricier side of the class. Normalized for capacity, it beats 52% of washing machine models we track, an average result for the class. Its IMEF of 2.38 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Ge GTW490ACJ7WS at $25/yr runs a little cheaper and the Ge Profile PFQ97HS*V*** at $25/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 WT5680H*A's $25/yr adds up to roughly $250 in electricity alone, before purchase price or repairs.
By the numbers
The Lg WT5680H*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 $25/yr, here is what the Lg WT5680H*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 WT5680H*A costs about $250. That is roughly $50 more than the class median, which would run closer to $200 over the same ten years.
How the Lg WT5680H*A compares
The washing machine class we track runs from $7 to $58 a year. At $25/yr, it runs about $5 a year above the class median of $20, and it is about $18 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5 cu ft, the Lg WT5680H*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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. Its IMEF of 2.38, below the class median of 2.76, reflects integrated modified energy factor: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.
- 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 WT5680H*A cheap to run?
Not especially. At $25 a year it ranks #273 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 WT5680H*A cost per month?
Roughly $2.09/mo, spreading the $25/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 135 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $25 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg WT5680H*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.
