Model
Black+Decker BUC1100XB
Rank #167 means 166 of the 622 freezer models we track cost less to run each year; the 42nd efficiency percentile means it uses less energy for its size than 42% of those models.
What does the Black+Decker BUC1100XB cost to run per year?
The Black+Decker BUC1100XB costs about $66 a year to run, which beats most of the 622 freezer models we track; it ranks #167. It uses 10% less energy than the U.S. federal standard model in its class, which would cost about $73/yr to run, a saving of roughly $7 a year. Capacity-normalized, it ranks ahead of 42% of freezer models we track, right in the class's middle band. This class has no published efficiency-factor figure beyond annual kWh itself, so at 11 cu ft (the class spans 1.1 to 23), size is the clearest lever we can point to for this model's running cost.
Immediately around it on the leaderboard, the Avanti VF108K0W at $66/yr runs a little cheaper and the Black+Decker BUC1100XS at $66/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A freezer typically stays in service for somewhere around 14 years; over that span, the Black+Decker BUC1100XB's $66/yr adds up to roughly $924 in electricity alone, before purchase price or repairs.
Also sold as: Black+Decker BUC1100XS, Black+Decker BUC1100XW, Vitara VLUF1101EBE, Vitara VLUF1101ESE, Vitara VLUF1101EWE.
By the numbers
The Black+Decker BUC1100XB 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 $66/yr, here is what the Black+Decker BUC1100XB 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 BUC1100XB costs about $660. That is roughly $70 less than a standard model in its class, which would run closer to $730 over the same ten years.
How the Black+Decker BUC1100XB compares
The freezer class we track runs from $25 to $120 a year. At $66/yr, it runs about $9 a year cheaper than the class median of $75, and it is about $41 a year more than the cheapest freezer to run at $25. Against the US federal standard model for its class at about $73/yr, the Black+Decker BUC1100XB uses 10% less energy.
What drives its running cost
At 11 cu ft, the Black+Decker BUC1100XB is a mid-size freezer for its class, which spans 1.1 to 23 cu ft with a median of 13.8 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. As with refrigerators, more cubic feet of frozen storage generally means a bigger compressor and a higher annual energy figure.
- Insulation and defrost type. Better-insulated cabinets lose less cold to the surrounding room, and frost-free (automatic-defrost) freezers run a periodic heating element that a manual-defrost model does not.
- Chest vs upright design. Door orientation affects how much cold air escapes per opening: top-opening chest designs generally hold cold better than front-opening upright ones.
Common questions
Is the Black+Decker BUC1100XB cheap to run?
Yes. Its $66/yr running cost puts it at rank #167 of 622, below what most freezer models we track cost to run.
How much does the Black+Decker BUC1100XB cost per month?
About $5.48 a month, which is the $66 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: 354 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $66 a year. It covers electricity only, not the purchase price, water, or installation.
How efficient is the Black+Decker BUC1100XB for its size?
42nd percentile once size is factored in, a fairly typical result for the class.
