Model
Midea MLH52N7AWW
Rank #78 means 77 of the 388 washing machine models we track cost less to run each year; the 78th efficiency percentile means it uses less energy for its size than 78% of those models.
What does the Midea MLH52N7AWW cost to run per year?
At roughly $18 a year to run, ranking #78 of 388, the Midea MLH52N7AWW costs less than the typical washing machine model we track. Its size-adjusted efficiency percentile of 78 is comfortably above the class median. 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 Lg WM3470C* at $18/yr runs a little cheaper and the Samsung WF45R61**A* at $18/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 MLH52N7AWW's $18/yr adds up to roughly $180 in electricity alone, before purchase price or repairs.
Also sold as: Samsung WF45R61**A*, Samsung WF45R63**A*, Samsung WF45T62**A*.
By the numbers
The Midea MLH52N7AWW 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 $18/yr, here is what the Midea MLH52N7AWW 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 MLH52N7AWW costs about $180. That is roughly $20 less than the class median, which would run closer to $200 over the same ten years.
How the Midea MLH52N7AWW compares
The washing machine class we track runs from $7 to $58 a year. At $18/yr, it runs about $2 a year cheaper than the class median of $20, and it is about $11 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.5 cu ft, the Midea MLH52N7AWW 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. Beyond size, its IMEF of 2.76, above the class median of 2.76, is the class's own efficiency yardstick, integrated modified energy factor, and it is what separates two similarly sized models with different running costs.
- 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 MLH52N7AWW cheap to run?
Yes. Its $18/yr running cost puts it at rank #78 of 388, below what most washing machine models we track cost to run.
How much does the Midea MLH52N7AWW cost per month?
About $1.47 a month, which is the $18 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: 95 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $18 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Midea MLH52N7AWW for its size?
78th percentile once size is factored in, a fairly typical result for the class.
