Model
Elisii DFFFD1738-28RS
Rank #310 means 309 of the 1,000 refrigerator models we track cost less to run each year; the 93rd efficiency percentile means it uses less energy for its size than 93% of those models.
What does the Elisii DFFFD1738-28RS cost to run per year?
The Elisii DFFFD1738-28RS costs about $50 a year to run, which beats most of the 1,000 refrigerator models we track; it ranks #310. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $56/yr to run, a saving of roughly $6 a year. Its size-adjusted efficiency percentile of 93 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 14 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 Edgestar CRF321SS at $50/yr runs a little cheaper and the Forno FFFFD1738-28WHT-RS at $50/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 Elisii DFFFD1738-28RS's $50/yr adds up to roughly $600 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BUC1400XS.
By the numbers
The Elisii DFFFD1738-28RS 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 $50/yr, here is what the Elisii DFFFD1738-28RS adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Elisii DFFFD1738-28RS costs about $500. That is roughly $60 less than a standard model in its class, which would run closer to $560 over the same ten years.
How the Elisii DFFFD1738-28RS compares
The refrigerator class we track runs from $8 to $149 a year. At $50/yr, it runs about $14 a year cheaper than the class median of $64, and it is about $42 a year more than the cheapest refrigerator to run at $8. Against the US federal standard model for its class at about $56/yr, the Elisii DFFFD1738-28RS uses 10% less energy.
What drives its running cost
At 14 cu ft, the Elisii DFFFD1738-28RS 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, right in the middle of the capacity range, so capacity is roughly a wash compared with the rest of the class.
- 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 Elisii DFFFD1738-28RS cheap to run?
Yes. Its $50/yr running cost puts it at rank #310 of 1,000, below what most refrigerator models we track cost to run.
How much does the Elisii DFFFD1738-28RS cost per month?
About $4.18 a month, which is the $50 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: 270 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $50 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Elisii DFFFD1738-28RS for its size?
93rd percentile once size is factored in, a fairly typical result for the class.
