Dehumidifier Cost
Estimate how much running a dehumidifier adds to your bill.
About Dehumidifier Cost
A dehumidifier draws steady power for many hours, so its cost is the wattage times daily run time converted to kilowatt-hours and charged at the rate. Because it runs almost continuously in damp homes, a dehumidifier can quietly add a significant amount to the electric bill.
Formula
Dehumidifier Cost
Cost = watts x hours x rate / 1000
