What does the Black+Decker BD10NWES cost to run per year?

The Black+Decker BD10NWES costs about $93 a year to run, which beats most of the 404 room air conditioner models we track; it ranks #143. It uses 38% less energy than the U.S. federal standard model in its class, which would cost about $150/yr to run, a saving of roughly $57 a year. Capacity-normalized, it ranks ahead of 65% of room air conditioner models we track, a reasonably strong result for the class. Its CEER of 15 reflects combined energy efficiency ratio, one of the class's core efficiency levers.

Immediately around it on the leaderboard, the Ge Profile AHTR10ACH2 at $90/yr runs a little cheaper and the Century RXTS-101A at $93/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A room air conditioner typically stays in service for somewhere around 10 years; over that span, the Black+Decker BD10NWES's $93/yr adds up to roughly $930 in electricity alone, before purchase price or repairs.

What it costs you over time

Running cost is an every-year number, so it compounds. At $93/yr, here is what the Black+Decker BD10NWES adds up to before purchase price, water, or repairs enter the math.

1 year$93
5 years$465
10 years$930

Left running for a decade at today's US average rate, the Black+Decker BD10NWES costs about $930. That is roughly $570 less than a standard model in its class, which would run closer to $1500 over the same ten years.

How the Black+Decker BD10NWES compares

The room air conditioner class we track runs from $51 to $389 a year. At $93/yr, it runs about $6 a year cheaper than the class median of $99, and it is about $42 a year more than the cheapest room air conditioner to run at $51. Against the US federal standard model for its class at about $150/yr, the Black+Decker BD10NWES uses 38% less energy.

What drives its running cost

At 10000 BTU/hr, the Black+Decker BD10NWES is a small room air conditioner for its class, which spans 5000 to 34100 BTU/hr with a median of 10100 BTU/hr, at the small end of the class, capacity itself is doing a lot of the work to keep that figure down, separate from how efficient the unit actually is. Its CEER of 15, above the class median of 15, reflects combined energy efficiency ratio: a higher figure means it wrings more useful work out of every kilowatt-hour, so it is the efficiency lever to weigh against raw size.

  • Combined Energy Efficiency Ratio (CEER). Two units with the same BTU rating can post very different running costs, and CEER is the figure that explains most of that gap.
  • BTU cooling capacity. BTU rating scales with room size, and it is usually the first driver of an air conditioner's running cost, ahead of its CEER figure.
  • Thermostat and mode usage. How the unit is actually operated, thermostat cycling versus a fixed setting, moves real electricity use more than the rated BTU or CEER figure alone.

Common questions

Is the Black+Decker BD10NWES cheap to run?

Yes. Its $93/yr running cost puts it at rank #143 of 404, below what most room air conditioner models we track cost to run.

How much does the Black+Decker BD10NWES cost per month?

About $7.73 a month, which is the $93 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: 500 kWh from ENERGY STAR times the US average of $0.1856/kWh comes to about $93 a year. It covers electricity only, not the purchase price, water, or installation.

How efficient is the Black+Decker BD10NWES for its size?

65th percentile once size is factored in, a fairly typical result for the class.
