Model
Perlick URD24W*1-5-****
Rank #3 means 2 of the 1,000 refrigerator models we track cost less to run each year; the 43rd efficiency percentile means it uses less energy for its size than 43% of those models.
What does the Perlick URD24W*1-5-**** cost to run per year?
Do the math and the Perlick URD24W*1-5-****'s $18/yr running cost puts it at rank #3 of 1,000, among the least expensive refrigerator models we track to keep running. It uses 45% less energy than the U.S. federal standard model in its class, which would cost about $33/yr to run, a saving of roughly $15 a year. Efficiency-wise, once size is accounted for, it sits right around the class median, ahead of 43% of the models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 3.1 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 Kalamazoo Outdoor Gourmet UKS15W*1-5-**** at $18/yr runs a little cheaper and the Liebherr UW3720 at $19/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 Perlick URD24W*1-5-****'s $18/yr adds up to roughly $216 in electricity alone, before purchase price or repairs. At rank #3 of 1,000, it is one of the single cheapest refrigerator models we track to run, in the top one percent on cost.
By the numbers
The Perlick URD24W*1-5-**** 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 $18/yr, here is what the Perlick URD24W*1-5-**** adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Perlick URD24W*1-5-**** costs about $180. That is roughly $150 less than a standard model in its class, which would run closer to $330 over the same ten years.
How the Perlick URD24W*1-5-**** compares
The refrigerator class we track runs from $8 to $149 a year. At $18/yr, it runs about $46 a year cheaper than the class median of $64, and it is about $10 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $33/yr, the Perlick URD24W*1-5-**** uses 45% less energy.
What drives its running cost
At 3.1 cu ft, the Perlick URD24W*1-5-**** is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, less capacity to service is usually the first reason a running-cost figure lands on the low side, before efficiency even enters the picture.
- 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 Perlick URD24W*1-5-**** cheap to run?
Yes. Its $18/yr running cost puts it at rank #3 of 1,000, below what most refrigerator models we track cost to run.
How much does the Perlick URD24W*1-5-**** cost per month?
About $1.53 a month, which is the $18 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: 99 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $18 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Perlick URD24W*1-5-**** for its size?
43rd 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.
