Model
Lg WM3275C*
Rank #60 means 59 of the 388 washing machine models we track cost less to run each year; the 85th efficiency percentile means it uses less energy for its size than 85% of those models.
What does the Lg WM3275C* cost to run per year?
The Lg WM3275C* costs about $17 a year to run and sits near the top of the cheapest-to-run leaderboard, rank #60 of 388. Efficiency-wise, once capacity is accounted for, it beats 85% of the class, a solidly strong result rather than a size-driven fluke. The IMEF figure of 2.92 on this model captures integrated modified energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Lg WM3270C* at $17/yr runs a little cheaper and the Samsung WF45T60**A* at $17/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 WM3275C*'s $17/yr adds up to roughly $170 in electricity alone, before purchase price or repairs.
Also sold as: Lg WM3085C*.
By the numbers
The Lg WM3275C* 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 $17/yr, here is what the Lg WM3275C* 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 WM3275C* costs about $170. That is roughly $30 less than the class median, which would run closer to $200 over the same ten years.
How the Lg WM3275C* compares
The washing machine class we track runs from $7 to $58 a year. At $17/yr, it runs about $3 a year cheaper than the class median of $20, and it is about $10 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.5 cu ft, the Lg WM3275C* 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, putting it squarely in the middle of the class on the size lever that drives most of the cost. Its IMEF of 2.92, above 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 WM3275C* cheap to run?
Yes, relatively. At $17 a year it ranks #60 of 388 washing machine models we track, in the cheaper part of its class to run.
How much does the Lg WM3275C* cost per month?
Roughly $1.39/mo, spreading the $17/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 90 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $17 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg WM3275C* for its size?
85th 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.
