Shopping for a new one
The Seasons SD35CB1 is already efficient for its category at $72/year. If you're shopping and comparing options, this is roughly what a well-chosen new dehumidifier costs to run.

Whether or not the Seasons SD35CB1 ever needs replacing, a repair is the more common failure for a dehumidifier, one a protection plan budgets for ahead of time.
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.
