Model
Fhiaba S240FR3U
Rank #363 means 362 of the 1,000 refrigerator models we track cost less to run each year; the 83rd efficiency percentile means it uses less energy for its size than 83% of those models.
What does the Fhiaba S240FR3U cost to run per year?
Among the 1,000 refrigerator models we track, the Fhiaba S240FR3U sits in the below-average-cost group, rank #363, at roughly $55 a year. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $62/yr to run, a saving of roughly $7 a year. Its size-adjusted efficiency percentile of 83 means the low running cost is not just a function of size; it is genuinely efficient for its 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 Kucht KR240TR at $55/yr runs a little cheaper and the Summit FF1101SS 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 Fhiaba S240FR3U's $55/yr adds up to roughly $660 in electricity alone, before purchase price or repairs.
By the numbers
The Fhiaba S240FR3U 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 Fhiaba S240FR3U 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 S240FR3U costs about $550. That is roughly $70 less than a standard model in its class, which would run closer to $620 over the same ten years.
How the Fhiaba S240FR3U 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 $62/yr, the Fhiaba S240FR3U uses 11% less energy.
What drives its running cost
At 13 cu ft, the Fhiaba S240FR3U 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.
- Counter depth vs standard depth. Standard-depth models generally offer more interior volume per unit of width than counter-depth models, a tradeoff between built-in looks and cubic feet.
- Interior volume. More cubic feet of cold air to maintain generally means a bigger compressor and a higher running-cost figure, even among efficient models.
- Compressor technology. How a compressor cycles, full on/off versus a variable-speed inverter design, is one of the biggest hidden differences behind two fridges with similar cubic feet but different running costs.
- Placement and ventilation. Ventilation clearance around the back and top matters more than most owners expect; a fridge starved of airflow runs its compressor longer to hold the same temperature.
Common questions
Is the Fhiaba S240FR3U cheap to run?
Yes. Its $55/yr running cost puts it at rank #363 of 1,000, below what most refrigerator models we track cost to run.
How much does the Fhiaba S240FR3U cost per month?
About $4.58 a month, which is the $55 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: 296 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $55 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Fhiaba S240FR3U for its size?
83rd percentile once size is factored in, a fairly typical result for the class.
