Model
Midea MLH27N4AWWC
Rank #19 means 18 of the 388 washing machine models we track cost less to run each year; the 55th efficiency percentile means it uses less energy for its size than 55% of those models.
What does the Midea MLH27N4AWWC cost to run per year?
Do the math and the Midea MLH27N4AWWC's $12/yr running cost puts it at rank #19 of 388, among the least expensive washing machine models we track to keep running. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 55% of the models we track. 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 Midea MLH25N7BWW at $12/yr runs a little cheaper and the Bosch WGA12400** at $13/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 MLH27N4AWWC's $12/yr adds up to roughly $120 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MLH27N4AWWC 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 $12/yr, here is what the Midea MLH27N4AWWC 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 MLH27N4AWWC costs about $120. That is roughly $80 less than the class median, which would run closer to $200 over the same ten years.
How the Midea MLH27N4AWWC compares
The washing machine class we track runs from $7 to $58 a year. At $12/yr, it runs about $8 a year cheaper than the class median of $20, and it is about $5 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.5 cu ft, the Midea MLH27N4AWWC 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). IMEF is this class's core efficiency yardstick; two washers with the same drum size can carry meaningfully different IMEF figures and running costs.
- Drum volume. A larger-capacity washer can wash more per load, which can lower cost per pound of laundry, but it also draws more water and energy per cycle if you are not filling it.
- Water heating. Most washers rely on your home's hot water supply, but internal-heater sanitize or hot-wash cycles use meaningfully more electricity than a cold or warm wash.
Common questions
Is the Midea MLH27N4AWWC cheap to run?
Yes. Its $12/yr running cost puts it at rank #19 of 388, below what most washing machine models we track cost to run.
How much does the Midea MLH27N4AWWC cost per month?
About $1.01 a month, which is the $12 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 65 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $12 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MLH27N4AWWC for its size?
55th 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.
