Model
Icebox IBCR25SUN
Rank #114 means 113 of the 1,000 refrigerator models we track cost less to run each year; the 10th efficiency percentile means it uses less energy for its size than 10% of those models.
What does the Icebox IBCR25SUN cost to run per year?
Few refrigerator models we track cost less to run than the Icebox IBCR25SUN: about $40 a year, rank #114 of 1,000. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $44/yr to run, a saving of roughly $4 a year. Normalized for capacity, it beats only 10% of refrigerator models we track, one of the weaker efficiency results we track for the class. It is a counter-depth model, built shallower to sit flush with kitchen cabinets, a design choice that typically trades away some interior volume (and so some running-cost headroom) for the built-in look.
Immediately around it on the leaderboard, the Galanz GL27S5 at $40/yr runs a little cheaper and the Sapphire SR243SSPRADA at $40/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 Icebox IBCR25SUN's $40/yr adds up to roughly $480 in electricity alone, before purchase price or repairs.
By the numbers
The Icebox IBCR25SUN 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 $40/yr, here is what the Icebox IBCR25SUN adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Icebox IBCR25SUN costs about $400. That is roughly $40 less than a standard model in its class, which would run closer to $440 over the same ten years.
How the Icebox IBCR25SUN compares
The refrigerator class we track runs from $8 to $149 a year. At $40/yr, it runs about $24 a year cheaper than the class median of $64, and it is about $32 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $44/yr, the Icebox IBCR25SUN uses 10% less energy.
What drives its running cost
At 2.5 cu ft, the Icebox IBCR25SUN is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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.
- 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.
- 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 Icebox IBCR25SUN cheap to run?
Yes, relatively. At $40 a year it ranks #114 of 1,000 refrigerator models we track, in the cheaper part of its class to run.
How much does the Icebox IBCR25SUN cost per month?
Roughly $3.31/mo, spreading the $40/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 214 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $40 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Icebox IBCR25SUN for its size?
10th percentile once size is factored in. That means its size-adjusted efficiency is not the main reason for the running-cost figure above; its capacity plays a large role too.
