Model
Miele WXI860
Rank #209 means 208 of the 388 washing machine models we track cost less to run each year; the 5th efficiency percentile means it uses less energy for its size than 5% of those models.
What does the Miele WXI860 cost to run per year?
At about $22 a year, the Miele WXI860 lands in the middle third of washing machine models we track on running cost, rank #209 of 388. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 5% of the models we track. Its IMEF of 2.13 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Miele WXF960 at $22/yr runs a little cheaper and the Miele WXR860 at $22/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 Miele WXI860's $22/yr adds up to roughly $220 in electricity alone, before purchase price or repairs.
Also sold as: Miele WWD160.
By the numbers
The Miele WXI860 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 $22/yr, here is what the Miele WXI860 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Miele WXI860 costs about $220. That is roughly $20 more than the class median, which would run closer to $200 over the same ten years.
How the Miele WXI860 compares
The washing machine class we track runs from $7 to $58 a year. At $22/yr, it runs about $2 a year above the class median of $20, and it is about $15 a year more than the cheapest washing machine to run at $7.
What drives its running cost
At 2.3 cu ft, the Miele WXI860 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. Beyond size, its IMEF of 2.13, below 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 Miele WXI860 cheap to run?
Roughly, yes. Its $22/yr figure is close to the class median, ranking #209 of 388, neither a bargain nor a splurge on running cost.
How much does the Miele WXI860 cost per month?
About $1.79 a month, which is the $22 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: 116 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $22 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Miele WXI860 for its size?
5th percentile once size is factored in, a fairly typical result for the class.
