Model
Kenmore KKTMWM7.5-W
Rank #522 means 521 of the 1,000 refrigerator models we track cost less to run each year; the 35th efficiency percentile means it uses less energy for its size than 35% of those models.
What does the Kenmore KKTMWM7.5-W cost to run per year?
The Kenmore KKTMWM7.5-W costs about $64 a year to run, a middle-of-the-pack figure at rank #522 of 1,000. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $72/yr to run, a saving of roughly $8 a year. Its 35th size-adjusted efficiency percentile is a step behind the class median, though not among the weakest results. At 7.5 cu ft, it is a mid-size 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 Galanz GLRF76TMRDER2 at $64/yr runs a little cheaper and the Kenmore KMR75TWEE at $64/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 KKTMWM7.5-W's $64/yr adds up to roughly $768 in electricity alone, before purchase price or repairs.

By the numbers
The Kenmore KKTMWM7.5-W 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 $64/yr, here is what the Kenmore KKTMWM7.5-W 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 KKTMWM7.5-W costs about $640. That is roughly $80 less than a standard model in its class, which would run closer to $720 over the same ten years.
How the Kenmore KKTMWM7.5-W compares
The refrigerator class we track runs from $8 to $149 a year. At $64/yr, it sits right on the class median of $64, and it is about $56 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $72/yr, the Kenmore KKTMWM7.5-W uses 10% less energy.
What drives its running cost
At 7.5 cu ft, the Kenmore KKTMWM7.5-W is a mid-size refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- 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 KKTMWM7.5-W cheap to run?
It is about average. At $64 a year it ranks #522 of 1,000 refrigerator models we track, close to the middle of its class on running cost.
How much does the Kenmore KKTMWM7.5-W cost per month?
Roughly $5.37/mo, spreading the $64/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 347 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $64 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Kenmore KKTMWM7.5-W for its size?
35th percentile once size is factored in, a fairly typical result for the class.
