Model
Hallman HRBIAR36PR
Rank #505 means 504 of the 1,000 refrigerator models we track cost less to run each year; the 96th efficiency percentile means it uses less energy for its size than 96% of those models.
What does the Hallman HRBIAR36PR cost to run per year?
The Hallman HRBIAR36PR costs about $64 a year to run, a fairly typical figure for the class; it ranks #505 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 96 means the low running cost is not just a function of size; almost nothing in the class beats it on efficiency once capacity is accounted for. This class has no published efficiency-factor figure beyond annual kWh itself, so at 20 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 Frigidaire FGFR797-6COM at $64/yr runs a little cheaper and the Kucht KR360TR 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 Hallman HRBIAR36PR's $64/yr adds up to roughly $768 in electricity alone, before purchase price or repairs.

By the numbers
The Hallman HRBIAR36PR 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 Hallman HRBIAR36PR adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Hallman HRBIAR36PR 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 Hallman HRBIAR36PR 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 Hallman HRBIAR36PR uses 11% less energy.
What drives its running cost
At 20 cu ft, the Hallman HRBIAR36PR is a large refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, and larger refrigerator models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light.
- 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 Hallman HRBIAR36PR cheap to run?
Roughly, yes. Its $64/yr figure is close to the class median, ranking #505 of 1,000, neither a bargain nor a splurge on running cost.
How much does the Hallman HRBIAR36PR 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 Hallman HRBIAR36PR for its size?
96th percentile once size is factored in, a fairly typical result for the class.
