Model
Summit FF1089**
Rank #368 means 367 of the 1,000 refrigerator models we track cost less to run each year; the 51st efficiency percentile means it uses less energy for its size than 51% of those models.
What does the Summit FF1089** cost to run per year?
Ranking #368 of 1,000, the Summit FF1089** is in the cheaper half of its class to run, at about $55 a year. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $62/yr to run, a saving of roughly $7 a year. Adjusted for size, it is more efficient than 51% of refrigerator models we track, a middling result. At 10.1 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 Professional Series PS-RF262-I6A at $55/yr runs a little cheaper and the Tcl TRT10T4** 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 FF1089**'s $55/yr adds up to roughly $660 in electricity alone, before purchase price or repairs.

By the numbers
The Summit FF1089** 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 FF1089** 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 FF1089** costs about $550. That is roughly $70 less than a standard model in its class, which would run closer to $620 over the same ten years.
How the Summit FF1089** 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 $62/yr, the Summit FF1089** uses 11% less energy.
What drives its running cost
At 10.1 cu ft, the Summit FF1089** 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 Summit FF1089** cheap to run?
Yes, relatively. At $55 a year it ranks #368 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Summit FF1089** cost per month?
Roughly $4.59/mo, spreading the $55/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 297 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $55 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Summit FF1089** for its size?
51st percentile once size is factored in, a fairly typical result for the class.
