Dehumidifier running cost calculator

Estimate daily, weekly, monthly and yearly running cost before buying. Use the wattage from the product listing or manual, then adjust hours and electricity price.

Many dehumidifiers cycle on and off once the room reaches target humidity, so real usage may be lower than a worst-case constant run.

Typical wattage

Small compressor dehumidifiers often sit around 150–300W. Larger compressor models and desiccant units can use more, especially in laundry or boost modes.

How to compare

A more powerful model may cost more per hour but remove moisture faster. Compare both wattage and how long you expect to run it each day.

Buying next

If the monthly cost looks high, compare quieter efficient models and use a hygrometer so you are not running the unit when the room is already dry enough.
