Model
Kenmore 17747
Rank #157 means 156 of the 1,000 refrigerator models we track cost less to run each year; the 22nd efficiency percentile means it uses less energy for its size than 22% of those models.
What does the Kenmore 17747 cost to run per year?
Do the math and the Kenmore 17747's $41/yr puts it at rank #157 of 1,000, one of the more affordable refrigerator models we track to keep running. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $46/yr to run, a saving of roughly $5 a year. Adjusted for size, it is only more efficient than 22% of refrigerator models we track, so part of its running cost comes from its capacity rather than efficiency alone. At 3.4 cu ft, it is a small 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 Insignia NS-CF33BK3 at $41/yr runs a little cheaper and the Koolatron KBC-88W at $41/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 Kenmore 17747's $41/yr adds up to roughly $492 in electricity alone, before purchase price or repairs.

By the numbers
The Kenmore 17747 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 $41/yr, here is what the Kenmore 17747 adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Kenmore 17747 costs about $410. That is roughly $50 less than a standard model in its class, which would run closer to $460 over the same ten years.
How the Kenmore 17747 compares
The refrigerator class we track runs from $8 to $149 a year. At $41/yr, it runs about $23 a year cheaper than the class median of $64, and it is about $33 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $46/yr, the Kenmore 17747 uses 11% less energy.
What drives its running cost
At 3.4 cu ft, the Kenmore 17747 is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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 Kenmore 17747 cheap to run?
Yes, relatively. At $41 a year it ranks #157 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Kenmore 17747 cost per month?
Roughly $3.4/mo, spreading the $41/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 220 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $41 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Kenmore 17747 for its size?
22nd 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.
