Dehumidifier cost calculator
How Much Does a Dehumidifier Cost to Run?
Estimate a dehumidifier's hourly, monthly, and annual electricity cost from its wattage, run time, and your electricity price.
Cost estimate
Calculate your electricity cost
Estimated energy use0 kWh/day
Estimated monthly energy0 kWh/month
Cost = watts ÷ 1,000 × hours used × electricity price.
Example
How the starting estimate works
At 500 watts for 8 hours per day, the starting example uses 4 kWh per day.
Real-world use
Humidity control changes run time.
The compressor may cycle off once the target humidity is reached. Basement moisture, temperature, unit size, fan settings, and the humidity setpoint all affect actual energy use.
