Dehumidifier electricity cost calculator
Estimate dehumidifier running cost using compressor power, daily schedule, humidity-driven duty cycle, and local tariff.
Transparent method
The calculation
Cost = compressor kW × scheduled hours × duty cycle × tariffLike an air conditioner, a compressor dehumidifier cycles as the target humidity is reached. Damp conditions, room leakage, and set point determine active runtime.

Run three scenarios.
01
MaintenanceUse a low duty cycle after the room dries.
02
Typical damp roomStart around 60% active runtime.
03
Laundry or floodingTest a high-duty temporary case.
Use the result well
What can change the answer?
- Desiccant units have a different power profile.
- Cold rooms can reduce compressor extraction performance.
- A blocked filter can increase runtime.
