Model
Summit LTM10SS
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 LTM10SS cost to run per year?
Ranking #366 of 1,000, the Summit LTM10SS 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 $61/yr to run, a saving of roughly $6 a year. Normalized for capacity, it beats 49% of refrigerator models we track, an average result for the class. At 10 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 FF1101SS at $55/yr runs a little cheaper and the Summit STM10W 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 LTM10SS's $55/yr adds up to roughly $660 in electricity alone, before purchase price or repairs.

By the numbers
The Summit LTM10SS 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 LTM10SS 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 LTM10SS 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 LTM10SS 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 LTM10SS uses 11% less energy.
What drives its running cost
At 10 cu ft, the Summit LTM10SS 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. 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 LTM10SS cheap to run?
Yes, relatively. At $55 a year it ranks #366 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Summit LTM10SS cost per month?
Roughly $4.58/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 296 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 LTM10SS for its size?
49th percentile once size is factored in, a fairly typical result for the class.
