Model
Black+Decker BUC1400XS
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 Black+Decker BUC1400XS cost to run per year?
Among the 1,000 refrigerator models we track, the Black+Decker BUC1400XS sits in the below-average-cost group, rank #310, at roughly $50 a year. 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 means the low running cost is not just a function of size; it is genuinely efficient for its class. 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 West Bend WB0440ARB* at $50/yr runs a little cheaper and the Edgestar CRF321SS 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 Black+Decker BUC1400XS's $50/yr adds up to roughly $600 in electricity alone, before purchase price or repairs.
Also sold as: Elisii DFFFD1738-28RS, Forno FFFFD1738-28WHT-RS.
By the numbers
The Black+Decker BUC1400XS 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 Black+Decker BUC1400XS adds up to before purchase price, water, or repairs enter the math.
Left running for a decade at today's US average rate, the Black+Decker BUC1400XS 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 Black+Decker BUC1400XS 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 Black+Decker BUC1400XS uses 10% less energy.
What drives its running cost
At 14 cu ft, the Black+Decker BUC1400XS 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 Black+Decker BUC1400XS 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 Black+Decker BUC1400XS 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 Black+Decker BUC1400XS for its size?
93rd percentile once size is factored in, a fairly typical result for the class.
