Model
Fhiaba S300FR3DU
Rank #423 means 422 of the 1,000 refrigerator models we track cost less to run each year; the 94th efficiency percentile means it uses less energy for its size than 94% of those models.
What does the Fhiaba S300FR3DU cost to run per year?
Ranking #423 of 1,000, the Fhiaba S300FR3DU runs at roughly $59 a year, neither the cheapest nor the priciest in its class. It uses 12% less energy than the U.S. federal standard model in its class, which would cost about $68/yr to run, a saving of roughly $9 a year. Normalized for capacity, it ranks ahead of 94% of refrigerator models we track on efficiency, a genuinely strong showing. 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 Cuisinart CCF-31 at $59/yr runs a little cheaper and the Frigidaire EFR920-SLATE-6COM at $59/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 Fhiaba S300FR3DU's $59/yr adds up to roughly $708 in electricity alone, before purchase price or repairs.

By the numbers
The Fhiaba S300FR3DU 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 $59/yr, here is what the Fhiaba S300FR3DU adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Fhiaba S300FR3DU costs about $590. That is roughly $90 less than a standard model in its class, which would run closer to $680 over the same ten years.
How the Fhiaba S300FR3DU compares
The refrigerator class we track runs from $8 to $149 a year. At $59/yr, it runs about $5 a year cheaper than the class median of $64, and it is about $51 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $68/yr, the Fhiaba S300FR3DU uses 12% less energy.
What drives its running cost
At 16.9 cu ft, the Fhiaba S300FR3DU 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.
- 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 Fhiaba S300FR3DU cheap to run?
It is about average. At $59 a year it ranks #423 of 1,000 refrigerator models we track, close to the middle of its class on running cost.
How much does the Fhiaba S300FR3DU cost per month?
Roughly $4.95/mo, spreading the $59/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 320 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $59 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Fhiaba S300FR3DU for its size?
94th percentile once size is factored in, a fairly typical result for the class.
