How this is calculated

Annual energy use is the figure ENERGY STAR lists for this model under typical test conditions. It is not measured in your home.
Yearly cost = annual kWh × your rate. Monthly cost is the yearly cost divided by 12, a flat average. Five-year cost keeps the rate constant; prices will change.
Statewide averages are not your utility’s tariff. Use your bill’s rate for a closer number.
We do not estimate watts or hourly cost: the source data does not include them.

Frequently asked questions

How much electricity does the BLACK+DECKER BDM08C use?

ENERGY STAR lists 375 kWh per year under typical test conditions, which is calculated with U.S. Department of Energy test procedures for a typical cooling season. Your use will differ with the climate, how many hours a day you cool and the temperature you set.

How much does it cost to run?

At statewide average residential prices, the listed annual use costs about $47.70 in Louisiana and $180.00 in Hawaii (EIA, 2026-07). Your own utility rate may be different; enter it in the calculator.

How does the BLACK+DECKER BDM08C compare with similar models?

Among 235 ENERGY STAR certified window models with a similar cooling capacity, it ranks 30th lowest in annual energy use. Its 375 kWh per year is 6% below the median of 400 kWh.

What does the CEER number mean?

The combined energy efficiency ratio is the cooling output in BTU for each watt-hour of electricity used. This model is listed at 16 BTU/Wh. A higher number means more cooling for the same electricity.
