Model
Miele K 2911 SF
Rank #408 means 407 of the 1,000 refrigerator models we track cost less to run each year; the 98th efficiency percentile means it uses less energy for its size than 98% of those models.
What does the Miele K 2911 SF cost to run per year?
Do the math and the Miele K 2911 SF's $58/yr puts it at rank #408 of 1,000, right around the class average. It uses 21% less energy than the U.S. federal standard model in its class, which would cost about $73/yr to run, a saving of roughly $15 a year. Normalized for capacity, it ranks ahead of 98% of refrigerator models we track on efficiency, an exceptional showing for the class. At 20.6 cu ft, it is a large refrigerator for the class, which runs 1.2 to 31.7 cu ft; size and efficiency are the two levers behind the figure above, and this dataset does not carry a separate efficiency-factor column for this class.
Immediately around it on the leaderboard, the Upstreman BD321 at $58/yr runs a little cheaper and the Black+Decker BUC2120M* at $58/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A refrigerator typically stays in service for somewhere around 12 years; over that span, the Miele K 2911 SF's $58/yr adds up to roughly $696 in electricity alone, before purchase price or repairs.
By the numbers
The Miele K 2911 SF 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 $58/yr, here is what the Miele K 2911 SF 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 K 2911 SF costs about $580. That is roughly $150 less than a standard model in its class, which would run closer to $730 over the same ten years.
How the Miele K 2911 SF compares
The refrigerator class we track runs from $8 to $149 a year. At $58/yr, it runs about $6 a year cheaper than the class median of $64, and it is about $50 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $73/yr, the Miele K 2911 SF uses 21% less energy.
What drives its running cost
At 20.6 cu ft, the Miele K 2911 SF is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, and larger refrigerator 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.
- Interior volume. Cubic feet of interior volume is the first thing that scales a fridge's running cost up or down, before compressor quality even enters the picture.
- Counter depth vs standard depth. Counter-depth models sit flush with cabinets but usually hold less interior volume than a standard-depth model of the same width, which can nudge the per-cubic-foot running cost either way.
- Compressor technology. Newer variable-speed (inverter) compressors modulate output instead of cycling fully on and off, which tends to use less energy for the same cooling job than an older fixed-speed compressor.
- Placement and ventilation. A fridge pushed tight against a wall or cabinet, or standing next to an oven or in direct sun, works harder to shed the heat its compressor produces, which can push real-world cost above the published figure.
Common questions
Is the Miele K 2911 SF cheap to run?
It is about average. At $58 a year it ranks #408 of 1,000 refrigerator models we track, close to the middle of its class on running cost.
How much does the Miele K 2911 SF cost per month?
Roughly $4.84/mo, spreading the $58/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 313 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $58 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Miele K 2911 SF for its size?
98th percentile once size is factored in, a fairly typical result for the class.
