Model
Summit FF1101SS
Rank #366 means 365 of the 1,000 refrigerator models we track cost less to run each year; the 49th efficiency percentile means it uses less energy for its size than 49% of those models.
What does the Summit FF1101SS cost to run per year?
At roughly $55 a year to run, ranking #366 of 1,000, the Summit FF1101SS costs less than the typical refrigerator model we track. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $61/yr to run, a saving of roughly $6 a year. Capacity-normalized, it ranks ahead of 49% of refrigerator models we track, right in the class's middle band. This class has no published efficiency-factor figure beyond annual kWh itself, so at 10 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 Fhiaba S240FR3U at $55/yr runs a little cheaper and the Summit LTM10SS at $55/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 FF1101SS's $55/yr adds up to roughly $660 in electricity alone, before purchase price or repairs.
Also sold as: Summit STM10W.
By the numbers
The Summit FF1101SS 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 $55/yr, here is what the Summit FF1101SS 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 FF1101SS costs about $550. That is roughly $60 less than a standard model in its class, which would run closer to $610 over the same ten years.
How the Summit FF1101SS compares
The refrigerator class we track runs from $8 to $149 a year. At $55/yr, it runs about $9 a year cheaper than the class median of $64, and it is about $47 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $61/yr, the Summit FF1101SS uses 11% less energy.
What drives its running cost
At 10 cu ft, the Summit FF1101SS 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, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- 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 FF1101SS cheap to run?
Yes. Its $55/yr running cost puts it at rank #366 of 1,000, below what most refrigerator models we track cost to run.
How much does the Summit FF1101SS cost per month?
About $4.58 a month, which is the $55 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: 296 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $55 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Summit FF1101SS for its size?
49th percentile once size is factored in, a fairly typical result for the class.
