Model
Midea MLHW27S7BCG
Rank #26 means 25 of the 388 washing machine models we track cost less to run each year; the 51st efficiency percentile means it uses less energy for its size than 51% of those models.
What does the Midea MLHW27S7BCG cost to run per year?
The Midea MLHW27S7BCG costs about $14 a year to run and sits near the top of the cheapest-to-run leaderboard, rank #26 of 388. Once capacity is factored in, its efficiency percentile of 51 is fairly typical for the class, neither a standout nor a laggard. Its IMEF of 2.76 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Midea MLH27N5AWWC at $14/yr runs a little cheaper and the Midea MLHW27S7BWW at $14/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 Midea MLHW27S7BCG's $14/yr adds up to roughly $140 in electricity alone, before purchase price or repairs.
Also sold as: Aeg WHP120.
By the numbers
The Midea MLHW27S7BCG 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 $14/yr, here is what the Midea MLHW27S7BCG adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Midea MLHW27S7BCG costs about $140. That is roughly $60 less than the class median, which would run closer to $200 over the same ten years.
How the Midea MLHW27S7BCG compares
The washing machine class we track runs from $7 to $58 a year. At $14/yr, it runs about $6 a year cheaper than the class median of $20, and it is about $7 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.7 cu ft, the Midea MLHW27S7BCG is a small washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture. Its IMEF of 2.76, 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 Midea MLHW27S7BCG cheap to run?
Yes, relatively. At $14 a year it ranks #26 of 388 washing machine models we track, in the cheaper part of its class to run.
How much does the Midea MLHW27S7BCG cost per month?
Roughly $1.16/mo, spreading the $14/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 75 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $14 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Midea MLHW27S7BCG for its size?
51st 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.
