Model
Midea MLH52S7AWW
Rank #194 means 193 of the 388 washing machine models we track cost less to run each year; the 77th efficiency percentile means it uses less energy for its size than 77% of those models.
What does the Midea MLH52S7AWW cost to run per year?
Do the math and the Midea MLH52S7AWW's $20/yr puts it at rank #194 of 388, right around the class average. Adjusted for size, it is more efficient than 77% of washing machine models we track, a solidly above-average result. At a IMEF of 2.92, 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 MLH52S7AGS at $20/yr runs a little cheaper and the Samsung WF50A85**A* 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 Midea MLH52S7AWW's $20/yr adds up to roughly $200 in electricity alone, before purchase price or repairs.

By the numbers
The Midea MLH52S7AWW 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 Midea MLH52S7AWW 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 MLH52S7AWW 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 Midea MLH52S7AWW 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 5.2 cu ft, the Midea MLH52S7AWW is a large washing machine for its class, which spans 1.9 to 6 cu ft with a median of 4.5 cu ft, and larger washing machine models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. Beyond size, its IMEF of 2.92, 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). 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 MLH52S7AWW cheap to run?
It is about average. At $20 a year it ranks #194 of 388 washing machine models we track, close to the middle of its class on running cost.
How much does the Midea MLH52S7AWW 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 Midea MLH52S7AWW for its size?
77th percentile once size is factored in, a fairly typical result for the class.
