Model
Maytag MHW8630H**
Rank #330 means 329 of the 388 washing machine models we track cost less to run each year; the 36th efficiency percentile means it uses less energy for its size than 36% of those models.
What does the Maytag MHW8630H** cost to run per year?
The Maytag MHW8630H** costs about $30 a year to run, well up the cost table for its class at rank #330 of 388. Capacity-normalized, it ranks ahead of just 36% of washing machine models we track, a soft spot worth weighing against the dollar figure. The IMEF figure of 2.76 on this model captures integrated modified energy factor, the main efficiency lever ENERGY STAR tracks for this class.
Immediately around it on the leaderboard, the Ge Profile PTW605B*R*** at $29/yr runs a little cheaper and the Ge GTW470BMM*** at $30/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 MHW8630H**'s $30/yr adds up to roughly $300 in electricity alone, before purchase price or repairs.
By the numbers
The Maytag MHW8630H** 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 $30/yr, here is what the Maytag MHW8630H** 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 MHW8630H** costs about $300. That is roughly $100 more than the class median, which would run closer to $200 over the same ten years.
How the Maytag MHW8630H** compares
The washing machine class we track runs from $7 to $58 a year. At $30/yr, it runs about $10 a year above the class median of $20, and it is about $23 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 5 cu ft, the Maytag MHW8630H** 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. The IMEF of 2.76 on this model, above the class median of 2.76, measures integrated modified energy factor; it is the number to compare directly against another model's IMEF if capacity is similar.
- 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 MHW8630H** cheap to run?
Its $30/yr running cost, rank #330 of 388, is above what most washing machine models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Maytag MHW8630H** cost per month?
About $2.46 a month, which is the $30 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: 159 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $30 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Maytag MHW8630H** for its size?
36th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
