Model
Forno FFRBI1844-36**
Rank #803 means 802 of the 1,000 refrigerator models we track cost less to run each year; the 56th efficiency percentile means it uses less energy for its size than 56% of those models.
What does the Forno FFRBI1844-36** cost to run per year?
The Forno FFRBI1844-36** holds rank #803 of 1,000 on running cost, at about $104 a year, a genuinely pricey result for the class. It uses 15% less energy than the U.S. federal standard model in its class, which would cost about $120/yr to run, a saving of roughly $16 a year. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 56% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 20 cu ft (the class spans 1.2 to 31.7), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Miele KFNF 9955 iDE at $103/yr runs a little cheaper and the Gaggenau RVB477790 at $104/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 Forno FFRBI1844-36**'s $104/yr adds up to roughly $1248 in electricity alone, before purchase price or repairs.

By the numbers
The Forno FFRBI1844-36** 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 $104/yr, here is what the Forno FFRBI1844-36** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Forno FFRBI1844-36** costs about $1040. That is roughly $160 less than a standard model in its class, which would run closer to $1200 over the same ten years.
How the Forno FFRBI1844-36** compares
The refrigerator class we track runs from $8 to $149 a year. At $104/yr, it runs about $40 a year above the class median of $64, and it is about $96 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $120/yr, the Forno FFRBI1844-36** uses 15% less energy.
What drives its running cost
At 20 cu ft, the Forno FFRBI1844-36** is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, size is usually the single biggest lever behind a running-cost figure, and at this end of the range there is more capacity to service, which tends to push the number up.
- 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.
- 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.
- 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 Forno FFRBI1844-36** cheap to run?
Its $104/yr running cost, rank #803 of 1,000, is above what most refrigerator models we track cost to run, so this is not one of the cheaper picks on electricity alone.
How much does the Forno FFRBI1844-36** cost per month?
About $8.66 a month, which is the $104 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: 560 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $104 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Forno FFRBI1844-36** for its size?
56th 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.
