Model
Unique UNQ-455L V AC
Rank #677 means 676 of the 1,000 refrigerator models we track cost less to run each year; the 64th efficiency percentile means it uses less energy for its size than 64% of those models.
What does the Unique UNQ-455L V AC cost to run per year?
At about $82 a year, the Unique UNQ-455L V AC costs more to run than most refrigerator models we track, rank #677 of 1,000. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $91/yr to run, a saving of roughly $9 a year. Efficiency-wise, once size is accounted for, it edges out 64% of the class, a modestly above-average showing. This class has no published efficiency-factor figure beyond annual kWh itself, so at 16.7 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 Unique UNQ-455L LG AC at $82/yr runs a little cheaper and the Ge GIE18GCN**** at $82/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 Unique UNQ-455L V AC's $82/yr adds up to roughly $984 in electricity alone, before purchase price or repairs.

By the numbers
The Unique UNQ-455L V AC 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 $82/yr, here is what the Unique UNQ-455L V AC adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Unique UNQ-455L V AC costs about $820. That is roughly $90 less than a standard model in its class, which would run closer to $910 over the same ten years.
How the Unique UNQ-455L V AC compares
The refrigerator class we track runs from $8 to $149 a year. At $82/yr, it runs about $18 a year above the class median of $64, and it is about $74 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $91/yr, the Unique UNQ-455L V AC uses 10% less energy.
What drives its running cost
At 16.7 cu ft, the Unique UNQ-455L V AC 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 Unique UNQ-455L V AC cheap to run?
Its $82/yr running cost, rank #677 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 Unique UNQ-455L V AC cost per month?
About $6.84 a month, which is the $82 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: 442 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $82 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Unique UNQ-455L V AC for its size?
64th 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.
