- Cost per hour: 0.2 kWh × $0.13 = $0.026
- Cost per day: × 10 hours = $0.26
- Month and year: × 30 days = $7.80, × 365 days = $94.90

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 full power about 50% of the time, because it cycles on and off.
- 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 Oklahoma. 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.
