Model
Sapphire SR243SSPRADA
Rank #115 means 114 of the 1,000 refrigerator models we track cost less to run each year; the 38th efficiency percentile means it uses less energy for its size than 38% of those models.
What does the Sapphire SR243SSPRADA cost to run per year?
Rank #115 of 1,000 puts the Sapphire SR243SSPRADA among the cheapest refrigerator models we track to keep running, at roughly $40 a year. It uses 31% less energy than the U.S. federal standard model in its class, which would cost about $57/yr to run, a saving of roughly $17 a year. Its size-adjusted efficiency percentile of 38 suggests its capacity is doing more work than its efficiency to keep the headline cost down. This class has no published efficiency-factor figure beyond annual kWh itself, so at 5.4 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 Icebox IBCR25SUN at $40/yr runs a little cheaper and the Whirlpool AMA27S1E 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 Sapphire SR243SSPRADA's $40/yr adds up to roughly $480 in electricity alone, before purchase price or repairs.
By the numbers
The Sapphire SR243SSPRADA 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 Sapphire SR243SSPRADA adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Sapphire SR243SSPRADA costs about $400. That is roughly $170 less than a standard model in its class, which would run closer to $570 over the same ten years.
How the Sapphire SR243SSPRADA 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 $57/yr, the Sapphire SR243SSPRADA uses 31% less energy.
What drives its running cost
At 5.4 cu ft, the Sapphire SR243SSPRADA is a mid-size refrigerator for its class, which spans 1.2 to 31.7 cu ft with a median of 12.6 cu ft, neither the size advantage of a small unit nor the size penalty of a large one applies here, so its running cost is a fairer test of efficiency alone.
- 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 Sapphire SR243SSPRADA cheap to run?
Yes. Its $40/yr running cost puts it at rank #115 of 1,000, below what most refrigerator models we track cost to run.
How much does the Sapphire SR243SSPRADA cost per month?
About $3.31 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: 214 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 Sapphire SR243SSPRADA for its size?
38th 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.
