About dehumidifier running costs
A dehumidifier cycles on and off with a humidistat, so real running time is well under 24 hours.
Typical sizes: 250 W, 400 W, 500 W, 700 W.
How to spend less: Set the target to 45 to 50% humidity. Lower than that wastes electricity.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average in Florida. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
