Model
Bud Light FR321-BULT-COM
Rank #129 means 128 of the 1,000 refrigerator models we track cost less to run each year; the 21st efficiency percentile means it uses less energy for its size than 21% of those models.
What does the Bud Light FR321-BULT-COM cost to run per year?
The Bud Light FR321-BULT-COM runs for about $40 a year, landing it near the bottom of the cost table at rank #129 of 1,000 refrigerator models we track. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $45/yr to run, a saving of roughly $5 a year. Size-adjusted, this model trails most of its class on efficiency, ahead of just 21% of refrigerator models we track. Its listing marks it counter-depth, meaning it sits nearly flush with surrounding cabinets rather than protruding a few extra inches like a standard-depth model; that shallower body usually means less interior volume for the same footprint.
Immediately around it on the leaderboard, the Bangson US-BSR-107 at $40/yr runs a little cheaper and the Danby Designer DCR032A2* at $40/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 Bud Light FR321-BULT-COM's $40/yr adds up to roughly $480 in electricity alone, before purchase price or repairs.
Also sold as: Bangson US-BSR-100.
By the numbers
The Bud Light FR321-BULT-COM 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 $40/yr, here is what the Bud Light FR321-BULT-COM adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Bud Light FR321-BULT-COM costs about $400. That is roughly $50 less than a standard model in its class, which would run closer to $450 over the same ten years.
How the Bud Light FR321-BULT-COM compares
The refrigerator class we track runs from $8 to $149 a year. At $40/yr, it runs about $24 a year cheaper than the class median of $64, and it is about $32 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $45/yr, the Bud Light FR321-BULT-COM uses 11% less energy.
What drives its running cost
At 3.2 cu ft, the Bud Light FR321-BULT-COM is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is.
- 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.
- 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.
- 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 Bud Light FR321-BULT-COM cheap to run?
Yes. Its $40/yr running cost puts it at rank #129 of 1,000, below what most refrigerator models we track cost to run.
How much does the Bud Light FR321-BULT-COM cost per month?
About $3.37 a month, which is the $40 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: 218 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $40 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Bud Light FR321-BULT-COM for its size?
21st 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.
