Model
Blomberg WM98220SX*
Rank #164 means 163 of the 388 washing machine models we track cost less to run each year; the 14th efficiency percentile means it uses less energy for its size than 14% of those models.
What does the Blomberg WM98220SX* cost to run per year?
The Blomberg WM98220SX* costs about $20 a year to run, a fairly typical figure for the class; it ranks #164 of 388. Efficiency-wise, once size is accounted for, it lags most of the class, ahead of only 14% of the models we track. Its IMEF of 2.1 reflects integrated modified energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Beko WFTV10733XC* at $20/yr runs a little cheaper and the Smeg WM24UWH 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 Blomberg WM98220SX*'s $20/yr adds up to roughly $200 in electricity alone, before purchase price or repairs.

By the numbers
The Blomberg WM98220SX* 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 Blomberg WM98220SX* adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Blomberg WM98220SX* 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 Blomberg WM98220SX* 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 2.3 cu ft, the Blomberg WM98220SX* 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. Its IMEF of 2.1, below 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 Blomberg WM98220SX* cheap to run?
Roughly, yes. Its $20/yr figure is close to the class median, ranking #164 of 388, neither a bargain nor a splurge on running cost.
How much does the Blomberg WM98220SX* cost per month?
About $1.64 a month, which is the $20 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: 106 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $20 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Blomberg WM98220SX* for its size?
14th percentile once size is factored in, a fairly typical result for the class.
