Model
Arctic King ARM45D5ASL
Rank #464 means 463 of the 1,000 refrigerator models we track cost less to run each year; the 16th efficiency percentile means it uses less energy for its size than 16% of those models.
What does the Arctic King ARM45D5ASL cost to run per year?
The Arctic King ARM45D5ASL holds rank #464 of 1,000 on running cost, at about $61 a year, an unremarkable but typical figure for the class. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $68/yr to run, a saving of roughly $7 a year. Size-adjusted, this model ranks near the bottom of its class on efficiency, ahead of just 16% of refrigerator models we track. This class has no published efficiency-factor figure beyond annual kWh itself, so at 4.5 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 Marathon MCR47W at $61/yr runs a little cheaper and the Frigidaire FRPE4536AV at $61/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 Arctic King ARM45D5ASL's $61/yr adds up to roughly $732 in electricity alone, before purchase price or repairs.
Also sold as: Frigidaire FRPE4536AV, Midea MRM45B2ASL, Midea MRM45D5BST.
By the numbers
The Arctic King ARM45D5ASL 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 $61/yr, here is what the Arctic King ARM45D5ASL adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Arctic King ARM45D5ASL costs about $610. That is roughly $70 less than a standard model in its class, which would run closer to $680 over the same ten years.
How the Arctic King ARM45D5ASL compares
The refrigerator class we track runs from $8 to $149 a year. At $61/yr, it runs about $3 a year cheaper than the class median of $64, and it is about $53 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $68/yr, the Arctic King ARM45D5ASL uses 11% less energy.
What drives its running cost
At 4.5 cu ft, the Arctic King ARM45D5ASL 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 Arctic King ARM45D5ASL cheap to run?
Roughly, yes. Its $61/yr figure is close to the class median, ranking #464 of 1,000, neither a bargain nor a splurge on running cost.
How much does the Arctic King ARM45D5ASL cost per month?
About $5.09 a month, which is the $61 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: 329 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $61 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Arctic King ARM45D5ASL for its size?
16th percentile once size is factored in, a fairly typical result for the class.
