Model
Sankey RF 1963 SS
Rank #556 means 555 of the 1,000 refrigerator models we track cost less to run each year; the 90th efficiency percentile means it uses less energy for its size than 90% of those models.
What does the Sankey RF 1963 SS cost to run per year?
Among the 1,000 refrigerator models we track, the Sankey RF 1963 SS's $67/yr running cost ranks it #556, close to dead center. It uses 11% less energy than the U.S. federal standard model in its class, which would cost about $75/yr to run, a saving of roughly $8 a year. Its size-adjusted efficiency percentile of 90 sits well above the class median, a clearly above-average efficiency result. This class has no published efficiency-factor figure beyond annual kWh itself, so at 18 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 Moffat MTE18HTKBB* at $67/yr runs a little cheaper and the Sub-Zero DEC3650R**/* at $67/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 Sankey RF 1963 SS's $67/yr adds up to roughly $804 in electricity alone, before purchase price or repairs.
By the numbers
The Sankey RF 1963 SS 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 $67/yr, here is what the Sankey RF 1963 SS adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Sankey RF 1963 SS costs about $670. That is roughly $80 less than a standard model in its class, which would run closer to $750 over the same ten years.
How the Sankey RF 1963 SS compares
The refrigerator class we track runs from $8 to $149 a year. At $67/yr, it runs about $3 a year above the class median of $64, and it is about $59 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $75/yr, the Sankey RF 1963 SS uses 11% less energy.
What drives its running cost
At 18 cu ft, the Sankey RF 1963 SS 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, putting it squarely in the middle of the class on the size lever that drives most of the cost.
- 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 Sankey RF 1963 SS cheap to run?
Roughly, yes. Its $67/yr figure is close to the class median, ranking #556 of 1,000, neither a bargain nor a splurge on running cost.
How much does the Sankey RF 1963 SS cost per month?
About $5.6 a month, which is the $67 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: 362 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $67 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Sankey RF 1963 SS for its size?
90th percentile once size is factored in, a fairly typical result for the class.
