Model
Frigidaire EFR115-C-RED-COM
Rank #31 means 30 of the 1,000 refrigerator models we track cost less to run each year; the 8th efficiency percentile means it uses less energy for its size than 8% of those models.
What does the Frigidaire EFR115-C-RED-COM cost to run per year?
Do the math and the Frigidaire EFR115-C-RED-COM's $29/yr running cost puts it at rank #31 of 1,000, among the least expensive refrigerator models we track to keep running. It uses 32% less energy than the U.S. federal standard model in its class, which would cost about $43/yr to run, a saving of roughly $14 a year. Size-adjusted, this model ranks near the bottom of its class on efficiency, ahead of just 8% of refrigerator models we track. Counter-depth construction, which this model has, generally means a shallower cabinet and less interior volume than a standard-depth model the same width, a tradeoff worth knowing if you are comparing it on cubic feet.
Immediately around it on the leaderboard, the Frigidaire GRWE5726AS at $29/yr runs a little cheaper and the Hisense HWS054N6SS at $29/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 EFR115-C-RED-COM's $29/yr adds up to roughly $348 in electricity alone, before purchase price or repairs.
By the numbers
The Frigidaire EFR115-C-RED-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 $29/yr, here is what the Frigidaire EFR115-C-RED-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 Frigidaire EFR115-C-RED-COM costs about $290. That is roughly $140 less than a standard model in its class, which would run closer to $430 over the same ten years.
How the Frigidaire EFR115-C-RED-COM compares
The refrigerator class we track runs from $8 to $149 a year. At $29/yr, it runs about $35 a year cheaper than the class median of $64, and it is about $21 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 EFR115-C-RED-COM uses 32% less energy.
What drives its running cost
At 1.6 cu ft, the Frigidaire EFR115-C-RED-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, and smaller refrigerator models generally cost less to run for the same job, all else being equal.
- 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 Frigidaire EFR115-C-RED-COM cheap to run?
Yes. Its $29/yr running cost puts it at rank #31 of 1,000, below what most refrigerator models we track cost to run.
How much does the Frigidaire EFR115-C-RED-COM cost per month?
About $2.44 a month, which is the $29 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: 158 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $29 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Frigidaire EFR115-C-RED-COM for its size?
8th 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.
