Model
Kenmore KKTMR18.2X30-SS
Rank #569 means 568 of the 1,000 refrigerator models we track cost less to run each year; the 91st efficiency percentile means it uses less energy for its size than 91% of those models.
What does the Kenmore KKTMR18.2X30-SS cost to run per year?
The Kenmore KKTMR18.2X30-SS holds rank #569 of 1,000 on running cost, at about $68 a year, an unremarkable but typical figure for the class. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $75/yr to run, a saving of roughly $7 a year. Few refrigerator models we track beat it on size-adjusted efficiency; it edges out 91% of the class once capacity is normalized. This class has no published efficiency-factor figure beyond annual kWh itself, so at 18.2 cu ft (the class spans 1.2 to 31.7), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Ge GTE18NSW**** at $68/yr runs a little cheaper and the Frigidaire FFHT1814YB at $68/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 KKTMR18.2X30-SS's $68/yr adds up to roughly $816 in electricity alone, before purchase price or repairs.
By the numbers
The Kenmore KKTMR18.2X30-SS 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 $68/yr, here is what the Kenmore KKTMR18.2X30-SS 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 KKTMR18.2X30-SS costs about $680. That is roughly $70 less than a standard model in its class, which would run closer to $750 over the same ten years.
How the Kenmore KKTMR18.2X30-SS compares
The refrigerator class we track runs from $8 to $149 a year. At $68/yr, it runs about $4 a year above the class median of $64, and it is about $60 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $75/yr, the Kenmore KKTMR18.2X30-SS uses 10% less energy.
What drives its running cost
At 18.2 cu ft, the Kenmore KKTMR18.2X30-SS is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, among refrigerator models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal.
- Interior volume. More cubic feet of cold air to maintain generally means a bigger compressor and a higher running-cost figure, even among efficient models.
- Counter depth vs standard depth. Standard-depth models generally offer more interior volume per unit of width than counter-depth models, a tradeoff between built-in looks and cubic feet.
- Compressor technology. How a compressor cycles, full on/off versus a variable-speed inverter design, is one of the biggest hidden differences behind two fridges with similar cubic feet but different running costs.
- Placement and ventilation. Ventilation clearance around the back and top matters more than most owners expect; a fridge starved of airflow runs its compressor longer to hold the same temperature.
Common questions
Is the Kenmore KKTMR18.2X30-SS cheap to run?
Roughly, yes. Its $68/yr figure is close to the class median, ranking #569 of 1,000, neither a bargain nor a splurge on running cost.
How much does the Kenmore KKTMR18.2X30-SS cost per month?
About $5.65 a month, which is the $68 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: 365 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $68 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Kenmore KKTMR18.2X30-SS for its size?
91st percentile once size is factored in, a fairly typical result for the class.
