Where this ranks
That's 35.4% above the dehumidifier category average of 378 kWh/yr, and ranks 401 of 546 certified dehumidifiers for annual running cost, 1 being cheapest. Every one of the 546 currently-certified dehumidifiers feeds that average, putting this model about $25/year over it. See how it's calculated on the how it is calculated page.

Within the BLACK+DECKER lineup
BLACK+DECKER makes 5 ENERGY STAR certified dehumidifiers; this one ranks 4 of 5 for running cost, between the brand's cheapest, the BDT08TW at $22/yr, and its priciest, the BDM50PWCDA at $98/yr.
Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Shopping for a new one
The BLACK+DECKER BDM50WCDA runs above its category average. If the dehumidifier you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $96/year every year.
Worth comparing a few current certified models before deciding.
Protecting what you have
A dehumidifier like the BLACK+DECKER BDM50WCDA is a real household expense whether or not it needs replacing yet; a protection plan is one way to budget for a repair rather than a full replacement.
The data behind this page
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Dehumidifier category page shows all 546 dehumidifiers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
