Model
Summit LRF182SSIM
Rank #559 means 558 of the 1,000 refrigerator models we track cost less to run each year; the 90th efficiency percentile means it uses less energy for its size than 90% of those models.
What does the Summit LRF182SSIM cost to run per year?
At about $67 a year, the Summit LRF182SSIM lands in the middle third of refrigerator models we track on running cost, rank #559 of 1,000. 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 $8 a year. Few refrigerator models we track beat it on size-adjusted efficiency; it edges out 90% of the class once capacity is normalized. This class has no published efficiency-factor figure beyond annual kWh itself, so at 18 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 Summit FF18W at $67/yr runs a little cheaper and the Monogram ZIR360NN**** 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 Summit LRF182SSIM's $67/yr adds up to roughly $804 in electricity alone, before purchase price or repairs.
Also sold as: Criterion 18TMF-B.
By the numbers
The Summit LRF182SSIM 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 $67/yr, here is what the Summit LRF182SSIM adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Summit LRF182SSIM costs about $670. That is roughly $80 less than a standard model in its class, which would run closer to $750 over the same ten years.
How the Summit LRF182SSIM compares
The refrigerator class we track runs from $8 to $149 a year. At $67/yr, it runs about $3 a year above the class median of $64, and it is about $59 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 Summit LRF182SSIM uses 10% less energy.
What drives its running cost
At 18 cu ft, the Summit LRF182SSIM 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 Summit LRF182SSIM cheap to run?
Roughly, yes. Its $67/yr figure is close to the class median, ranking #559 of 1,000, neither a bargain nor a splurge on running cost.
How much does the Summit LRF182SSIM cost per month?
About $5.61 a month, which is the $67 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: 363 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $67 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Summit LRF182SSIM for its size?
90th percentile once size is factored in, a fairly typical result for the class.
