Model
Lg WT7300C*
Rank #190 means 189 of the 388 washing machine models we track cost less to run each year; the 75th efficiency percentile means it uses less energy for its size than 75% of those models.
What does the Lg WT7300C* cost to run per year?
Do the math and the Lg WT7300C*'s $20/yr puts it at rank #190 of 388, right around the class average. Adjusted for size, it is more efficient than 75% of washing machine models we track, a solidly above-average result. The IMEF figure of 2.76 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 WT7250C* at $20/yr runs a little cheaper and the Magic Chef MCSFLW24W1 at $20/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 WT7300C*'s $20/yr adds up to roughly $200 in electricity alone, before purchase price or repairs.
Also sold as: Lg WT7250C*.
By the numbers
The Lg WT7300C* 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 $20/yr, here is what the Lg WT7300C* 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 WT7300C* costs about $200. That is roughly $0 less than the class median, which would run closer to $200 over the same ten years.
How the Lg WT7300C* compares
The washing machine class we track runs from $7 to $58 a year. At $20/yr, it sits right on the class median of $20, and it is about $13 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5 cu ft, the Lg WT7300C* 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 2.76 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). 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 WT7300C* cheap to run?
It is about average. At $20 a year it ranks #190 of 388 washing machine models we track, close to the middle of its class on running cost.
How much does the Lg WT7300C* cost per month?
Roughly $1.7/mo, spreading the $20/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 110 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $20 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Lg WT7300C* for its size?
75th percentile once size is factored in, a fairly typical result for the class.
