Weighing a replacement
Efficient as certified dehumidifiers go, $48/year is a reasonable baseline if you're comparing what else is on the market.

At $48/year just to run, a dehumidifier is worth protecting against an unplanned repair bill on top of that.
How this was checked
Nothing here is estimated from a nameplate wattage; the 256 kWh/yr is ENERGY STAR's own certified figure for this model. 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.
