Model
Premium Levella PRF7450VW
Rank #506 means 505 of the 1,000 refrigerator models we track cost less to run each year; the 34th efficiency percentile means it uses less energy for its size than 34% of those models.
What does the Premium Levella PRF7450VW cost to run per year?
The Premium Levella PRF7450VW costs about $64 a year to run, a fairly typical figure for the class; it ranks #506 of 1,000. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $72/yr to run, a saving of roughly $8 a year. Its size-adjusted efficiency percentile of 34 suggests its capacity is doing more work than its efficiency to keep the headline cost down. This class has no published efficiency-factor figure beyond annual kWh itself, so at 7.4 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 Kucht KR360TR at $64/yr runs a little cheaper and the Samsung RT16A6195** at $64/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 Premium Levella PRF7450VW's $64/yr adds up to roughly $768 in electricity alone, before purchase price or repairs.

By the numbers
The Premium Levella PRF7450VW 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 $64/yr, here is what the Premium Levella PRF7450VW adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Premium Levella PRF7450VW costs about $640. That is roughly $80 less than a standard model in its class, which would run closer to $720 over the same ten years.
How the Premium Levella PRF7450VW compares
The refrigerator class we track runs from $8 to $149 a year. At $64/yr, it sits right on the class median of $64, and it is about $56 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $72/yr, the Premium Levella PRF7450VW uses 11% less energy.
What drives its running cost
At 7.4 cu ft, the Premium Levella PRF7450VW 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 Premium Levella PRF7450VW cheap to run?
Roughly, yes. Its $64/yr figure is close to the class median, ranking #506 of 1,000, neither a bargain nor a splurge on running cost.
How much does the Premium Levella PRF7450VW cost per month?
About $5.34 a month, which is the $64 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: 345 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $64 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Premium Levella PRF7450VW for its size?
34th percentile once size is factored in, a fairly typical result for the class.
