A dehumidifier and an air conditioner do not provide identical service. A dehumidifier removes moisture and releases heat into the room; an air conditioner removes heat and moisture from the conditioned space. This calculator reports only the wattage, runtime, and electricity rate scenario you enter.

Summary
A dehumidifier and an air conditioner do not provide identical service. A dehumidifier removes moisture and releases heat into the room; an air conditioner removes heat and moisture from the conditioned space. This calculator reports only the wattage, runtime, and electricity rate scenario you enter.
Formula
30-day electricity cost = watts ÷ 1,000 × entered hours/day × 30 × electricity rate
Data used
Calculator results use user-entered wattage and usage hours, combined with residential electricity rates for the selected U.S. state or the rate entered from a utility bill.
