Model
Maytag MHW8150E**
Rank #40 means 39 of the 388 washing machine models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Maytag MHW8150E** cost to run per year?
Among the 388 washing machine models we track, the Maytag MHW8150E**'s $15/yr running cost ranks it #40, comfortably in the cheap-to-run group. Few washing machine models we track are more efficient for their size than this one; its size-adjusted efficiency percentile of 96 is near the top of the class. 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 MLHW31S2BWW at $14/yr runs a little cheaper and the Lg WM3420C* at $15/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 Maytag MHW8150E**'s $15/yr adds up to roughly $150 in electricity alone, before purchase price or repairs.
By the numbers
The Maytag MHW8150E** 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 $15/yr, here is what the Maytag MHW8150E** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Maytag MHW8150E** costs about $150. That is roughly $50 less than the class median, which would run closer to $200 over the same ten years.
How the Maytag MHW8150E** compares
The washing machine class we track runs from $7 to $58 a year. At $15/yr, it runs about $5 a year cheaper than the class median of $20, and it is about $8 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 4.5 cu ft, the Maytag MHW8150E** 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class. 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 Maytag MHW8150E** cheap to run?
Yes. Its $15/yr running cost puts it at rank #40 of 388, below what most washing machine models we track cost to run.
How much does the Maytag MHW8150E** cost per month?
About $1.22 a month, which is the $15 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: 79 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $15 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Maytag MHW8150E** for its size?
96th 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.
