Model
Summit LRF15B
Rank #471 means 470 of the 1,000 refrigerator models we track cost less to run each year; the 82nd efficiency percentile means it uses less energy for its size than 82% of those models.
What does the Summit LRF15B cost to run per year?
The Summit LRF15B costs about $62 a year to run, a middle-of-the-pack figure at rank #471 of 1,000. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $69/yr to run, a saving of roughly $7 a year. Efficiency-wise, once capacity is accounted for, it beats 82% of the class, a solidly strong result rather than a size-driven fluke. At 14.3 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 Summit FF156B at $62/yr runs a little cheaper and the Avanti AVFF146DLJ#** at $62/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 LRF15B's $62/yr adds up to roughly $744 in electricity alone, before purchase price or repairs.
Also sold as: Avanti FF14V0W.
By the numbers
The Summit LRF15B 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 $62/yr, here is what the Summit LRF15B 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 LRF15B costs about $620. That is roughly $70 less than a standard model in its class, which would run closer to $690 over the same ten years.
How the Summit LRF15B compares
The refrigerator class we track runs from $8 to $149 a year. At $62/yr, it runs about $2 a year cheaper than the class median of $64, and it is about $54 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $69/yr, the Summit LRF15B uses 11% less energy.
What drives its running cost
At 14.3 cu ft, the Summit LRF15B 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 LRF15B cheap to run?
It is about average. At $62 a year it ranks #471 of 1,000 refrigerator models we track, close to the middle of its class on running cost.
How much does the Summit LRF15B cost per month?
Roughly $5.13/mo, spreading the $62/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 332 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $62 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Summit LRF15B for its size?
82nd percentile once size is factored in, a fairly typical result for the class.
