Model
Miele KF 2911 SF
Rank #770 means 769 of the 1,000 refrigerator models we track cost less to run each year; the 61st efficiency percentile means it uses less energy for its size than 61% of those models.
What does the Miele KF 2911 SF cost to run per year?
At $99 a year to run, the Miele KF 2911 SF runs more expensively than most models in its class, ranking #770 of 1,000 refrigerator models we track. It uses 20% less energy than the U.S. federal standard model in its class, which would cost about $120/yr to run, a saving of roughly $21 a year. Its 61th size-adjusted efficiency percentile is a step ahead of the class median, though not among the very top results. At 19.6 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 Miele KFN 9859 iDE li at $98/yr runs a little cheaper and the Fisher & Paykel RF170A***J** at $99/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 KF 2911 SF's $99/yr adds up to roughly $1188 in electricity alone, before purchase price or repairs.
By the numbers
The Miele KF 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 $99/yr, here is what the Miele KF 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 KF 2911 SF costs about $990. That is roughly $210 less than a standard model in its class, which would run closer to $1200 over the same ten years.
How the Miele KF 2911 SF compares
The refrigerator class we track runs from $8 to $149 a year. At $99/yr, it runs about $35 a year above the class median of $64, and it is about $91 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $120/yr, the Miele KF 2911 SF uses 20% less energy.
What drives its running cost
At 19.6 cu ft, the Miele KF 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, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- 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 KF 2911 SF cheap to run?
Not especially. At $99 a year it ranks #770 of 1,000 refrigerator models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Miele KF 2911 SF cost per month?
Roughly $8.21/mo, spreading the $99/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 531 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $99 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Miele KF 2911 SF for its size?
61st 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.
