Model
Fhiaba S360FZ6IU
Rank #616 means 615 of the 622 freezer 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 Fhiaba S360FZ6IU cost to run per year?
Almost nothing we track in this class costs more to run than the Fhiaba S360FZ6IU: about $117 a year, rank #616 of 622. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $129/yr to run, a saving of roughly $12 a year. Adjusted for size, it is more efficient than 51% of freezer models we track, a middling result. At 20.1 cu ft, it is a large freezer for the class, which runs 1.1 to 23 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 Fhiaba S360FZ3IU at $117/yr runs a little cheaper and the Viking Range,Llc FDFZIC7360L at $117/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A freezer typically stays in service for somewhere around 14 years; over that span, the Fhiaba S360FZ6IU's $117/yr adds up to roughly $1638 in electricity alone, before purchase price or repairs. At rank #616 of 622, it sits at the very top of the cost range for its class, among the single priciest models we track to run.

By the numbers
The Fhiaba S360FZ6IU 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 $117/yr, here is what the Fhiaba S360FZ6IU 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 S360FZ6IU costs about $1170. That is roughly $120 less than a standard model in its class, which would run closer to $1290 over the same ten years.
How the Fhiaba S360FZ6IU compares
The freezer class we track runs from $25 to $120 a year. At $117/yr, it runs about $42 a year above the class median of $75, and it is about $92 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $129/yr, the Fhiaba S360FZ6IU uses 10% less energy.
What drives its running cost
At 20.1 cu ft, the Fhiaba S360FZ6IU is a large freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 cu ft, and larger freezer models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- Interior volume. Cubic feet of frozen storage is the first lever behind a freezer's running cost, ahead of insulation or defrost type.
- Insulation and defrost type. Two freezers of the same size can differ meaningfully on running cost based on insulation quality and whether they run an automatic-defrost heater.
- Chest vs upright design. Chest freezers open from the top, so cold air, which sinks, stays inside when the lid opens; upright freezers lose more cold air per door opening for a similar capacity.
Common questions
Is the Fhiaba S360FZ6IU cheap to run?
Not especially. At $117 a year it ranks #616 of 622 freezer models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Fhiaba S360FZ6IU cost per month?
Roughly $9.77/mo, spreading the $117/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 632 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $117 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Fhiaba S360FZ6IU for its size?
51st percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
