Model
Black+Decker BDM50PWCDA
Rank #423 means 422 of the 519 dehumidifier models we track cost less to run each year; the 71st efficiency percentile means it uses less energy for its size than 71% of those models.
What does the Black+Decker BDM50PWCDA cost to run per year?
Not many dehumidifier models we track cost more to run than the Black+Decker BDM50PWCDA: about $97 a year, rank #423 of 519. Normalized for capacity, it beats 71% of dehumidifier models we track, a better-than-average efficiency result. Its IEF of 2.01 reflects integrated energy factor, one of the class's core efficiency levers.
Immediately around it on the leaderboard, the Vissani VAD50PS1AWTS at $97/yr runs a little cheaper and the Frigidaire FHDD5034Y1 at $97/yr runs a little more, a sense of how tightly models are packed at this point in the ranking. A dehumidifier typically stays in service for somewhere around 8 years; over that span, the Black+Decker BDM50PWCDA's $97/yr adds up to roughly $776 in electricity alone, before purchase price or repairs.

By the numbers
The Black+Decker BDM50PWCDA 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 $97/yr, here is what the Black+Decker BDM50PWCDA 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 BDM50PWCDA costs about $970. That is roughly $330 more than the class median, which would run closer to $640 over the same ten years.
How the Black+Decker BDM50PWCDA compares
The dehumidifier class we track runs from $19 to $521 a year. At $97/yr, it runs about $33 a year above the class median of $64, and it is about $78 a year more than the cheapest dehumidifier to run at $19.
What drives its running cost
At 49.95 pints/day, the Black+Decker BDM50PWCDA is a large dehumidifier for its class, which spans 1.91 to 172.13 pints/day with a median of 32.46 pints/day, and larger dehumidifier models generally cost more to run than smaller ones in the same class, simply because there is more to keep cold, spin, heat, or light. Its IEF of 2.01, above the class median of 2.01, reflects integrated energy factor: 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.
- Integrated Energy Factor (IEF). Two dehumidifiers rated for the same pints per day can carry very different IEF figures, and IEF is what actually separates their running costs.
- Water removal capacity (pints/day). Pints-per-day rating scales with the space it is built for, and that rating is the first driver of how much power the compressor needs.
- Humidistat accuracy. How tightly a humidistat holds its target humidity determines how much of the day the compressor actually runs, on top of the unit's rated capacity and IEF.
Common questions
Is the Black+Decker BDM50PWCDA cheap to run?
Not especially. At $97 a year it ranks #423 of 519 dehumidifier models we track, in the pricier part of its class to run, though its size and features may still justify that for your needs.
How much does the Black+Decker BDM50PWCDA cost per month?
Roughly $8.04/mo, spreading the $97/yr estimate evenly across twelve months at $0.1856/kWh. Actual monthly bills swing with your rate and usage pattern.
How is this running-cost figure calculated?
We take the model's published annual energy use of 520 kWh from ENERGY STAR and multiply it by the US average residential electricity rate of $0.1856/kWh, giving about $97 a year. It is an electricity-only estimate and does not include purchase price, water, or installation.
How efficient is the Black+Decker BDM50PWCDA for its size?
71st percentile once size is factored in. That means its size-adjusted efficiency is a real factor in the running-cost figure above; its capacity plays a large role too.
