Dehumidifier Electricity Cost Calculator

Estimate electricity cost from your entered use

Quick Answer

Estimate a dehumidifier from its input watts and actual daily runtime, or use annual kWh published for the exact model. A humidistat may cycle the compressor, so runtime and duty cycle vary with temperature, humidity, target relative humidity, room size, and drainage setup. The result is an electricity-use estimate, not a guaranteed bill.

Summary

Estimate a dehumidifier from its input watts and actual daily runtime, or use annual kWh published for the exact model. A humidistat may cycle the compressor, so runtime and duty cycle vary with temperature, humidity, target relative humidity, room size, and drainage setup. The result is an electricity-use estimate, not a guaranteed bill.

Formula

Watts mode: daily kWh = watts ÷ 1,000 × actual runtime; annual mode: cost = labeled annual kWh × 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.

Limits

These estimates do not reproduce a utility bill. Actual costs depend on your tariff, taxes, appliance cycling, efficiency, and how you use the appliance.
