Model
Bertazzoni REF36FDFZXNT
Rank #915 means 914 of the 1,000 refrigerator models we track cost less to run each year; the 46th efficiency percentile means it uses less energy for its size than 46% of those models.
What does the Bertazzoni REF36FDFZXNT cost to run per year?
Rank #915 of 1,000 puts the Bertazzoni REF36FDFZXNT among the pricier refrigerator models we track to keep running, at roughly $122 a year. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $134/yr to run, a saving of roughly $12 a year. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 46% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 21.6 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 Samsung RF27CG5010** at $122/yr runs a little cheaper and the Midea MRQ22D4AST at $122/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 Bertazzoni REF36FDFZXNT's $122/yr adds up to roughly $1464 in electricity alone, before purchase price or repairs.
Also sold as: Midea MRQ22D4AST, Thorkitchen TRF3601FD.
By the numbers
The Bertazzoni REF36FDFZXNT 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 $122/yr, here is what the Bertazzoni REF36FDFZXNT adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Bertazzoni REF36FDFZXNT costs about $1220. That is roughly $120 less than a standard model in its class, which would run closer to $1340 over the same ten years.
How the Bertazzoni REF36FDFZXNT compares
The refrigerator class we track runs from $8 to $149 a year. At $122/yr, it runs about $58 a year above the class median of $64, and it is about $114 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $134/yr, the Bertazzoni REF36FDFZXNT uses 10% less energy.
What drives its running cost
At 21.6 cu ft, the Bertazzoni REF36FDFZXNT is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, among refrigerator models, bigger capacity is the most common reason a running-cost figure lands on the high side, all else being equal.
- 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 Bertazzoni REF36FDFZXNT cheap to run?
Its $122/yr running cost, rank #915 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 Bertazzoni REF36FDFZXNT cost per month?
About $10.18 a month, which is the $122 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: 658 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $122 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Bertazzoni REF36FDFZXNT for its size?
46th 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.
