Model
Fhiaba S240FZ6IU
Rank #550 means 549 of the 622 freezer models we track cost less to run each year; the 27th efficiency percentile means it uses less energy for its size than 27% of those models.
What does the Fhiaba S240FZ6IU cost to run per year?
Rank #550 of 622 puts the Fhiaba S240FZ6IU among the pricier freezer models we track to keep running, at roughly $94 a year. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $103/yr to run, a saving of roughly $9 a year. Capacity-normalized, it ranks ahead of just 27% of freezer models we track, a soft spot worth weighing against the dollar figure. This class has no published efficiency-factor figure beyond annual kWh itself, so at 12.1 cu ft (the class spans 1.1 to 23), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Fhiaba S240FZ3IU at $94/yr runs a little cheaper and the Viking Range,Llc FDFZIC7240L at $94/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 S240FZ6IU's $94/yr adds up to roughly $1316 in electricity alone, before purchase price or repairs.

By the numbers
The Fhiaba S240FZ6IU 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 $94/yr, here is what the Fhiaba S240FZ6IU 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 S240FZ6IU costs about $940. That is roughly $90 less than a standard model in its class, which would run closer to $1030 over the same ten years.
How the Fhiaba S240FZ6IU compares
The freezer class we track runs from $25 to $120 a year. At $94/yr, it runs about $19 a year above the class median of $75, and it is about $69 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $103/yr, the Fhiaba S240FZ6IU uses 10% less energy.
What drives its running cost
At 12.1 cu ft, the Fhiaba S240FZ6IU is a mid-size freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 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. As with refrigerators, more cubic feet of frozen storage generally means a bigger compressor and a higher annual energy figure.
- Insulation and defrost type. Better-insulated cabinets lose less cold to the surrounding room, and frost-free (automatic-defrost) freezers run a periodic heating element that a manual-defrost model does not.
- Chest vs upright design. Door orientation affects how much cold air escapes per opening: top-opening chest designs generally hold cold better than front-opening upright ones.
Common questions
Is the Fhiaba S240FZ6IU cheap to run?
Its $94/yr running cost, rank #550 of 622, is above what most freezer models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Fhiaba S240FZ6IU cost per month?
About $7.83 a month, which is the $94 annual estimate spread across twelve months at the US average rate of $0.1856/kWh. Your own bill scales with your local electricity rate and how heavily you use it.
How is this running-cost figure calculated?
The formula is annual kWh times price per kWh: 506 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $94 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Fhiaba S240FZ6IU for its size?
27th 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.
