Model
Frigidaire EFR189_AMZ-6COM
Rank #62 means 61 of the 1,000 refrigerator models we track cost less to run each year; the 4th efficiency percentile means it uses less energy for its size than 4% of those models.
What does the Frigidaire EFR189_AMZ-6COM cost to run per year?
The Frigidaire EFR189_AMZ-6COM holds rank #62 of 1,000 on running cost, at about $37 a year, a genuinely cheap result for the class. It uses 14% less energy than the U.S. federal standard model in its class, which would cost about $43/yr to run, a saving of roughly $6 a year. Capacity-normalized, it ranks ahead of just 4% of refrigerator models we track, near the bottom of every model we track in the class. This class has no published efficiency-factor figure beyond annual kWh itself, so at 1.6 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 EFR107-C-BLACK-6COM at $37/yr runs a little cheaper and the Frigidaire EFR190-SS-6COM at $37/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 Frigidaire EFR189_AMZ-6COM's $37/yr adds up to roughly $444 in electricity alone, before purchase price or repairs.
Also sold as: Frigidaire EFR190-SS-6COM.
By the numbers
The Frigidaire EFR189_AMZ-6COM 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 $37/yr, here is what the Frigidaire EFR189_AMZ-6COM adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Frigidaire EFR189_AMZ-6COM costs about $370. That is roughly $60 less than a standard model in its class, which would run closer to $430 over the same ten years.
How the Frigidaire EFR189_AMZ-6COM compares
The refrigerator class we track runs from $8 to $149 a year. At $37/yr, it runs about $27 a year cheaper than the class median of $64, and it is about $29 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $43/yr, the Frigidaire EFR189_AMZ-6COM uses 14% less energy.
What drives its running cost
At 1.6 cu ft, the Frigidaire EFR189_AMZ-6COM is a small refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, and smaller refrigerator models generally cost less to run for the same job, all else being equal.
- 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 Frigidaire EFR189_AMZ-6COM cheap to run?
Yes. Its $37/yr running cost puts it at rank #62 of 1,000, below what most refrigerator models we track cost to run.
How much does the Frigidaire EFR189_AMZ-6COM cost per month?
About $3.09 a month, which is the $37 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: 200 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $37 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Frigidaire EFR189_AMZ-6COM for its size?
4th 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.
