How much does a 400-watt dehumidifier cost per hour?

At $0.17/kWh, it costs $0.034 per hour. The maths: 400 W ÷ 1,000 = 0.4 kWh per hour, × $0.17 = $0.068. This page assumes it draws full power about 50% of the time, so the hourly figure shown is lower.

How much does it cost per month?

Used 10 hours a day for 30 days, it costs about $10.20 per month and uses 60 kWh. Change the hours in the calculator above to match how you use it.

How many kWh does it use?

2 kWh per day, 60 kWh per month and 730 kWh per year at 10 hours a day. A kWh is one kilowatt (1,000 W) used for one hour. It is the unit on your electricity bill.

How can I lower the cost?

Set the target to 45 to 50% humidity. Lower than that wastes electricity. Check your bill for the exact rate and enter it above.

Does my electricity rate change the answer?

Yes, a lot. At 10¢ per kWh the monthly cost is $6.00 and at 30¢ it is $18.00. Find your rate on your bill (total cost ÷ kWh used) and type it into the calculator.

How we worked it out

  1. Energy per hour: 400 W ÷ 1,000 = 0.4 kWh, × 50% of the time at full power = 0.2 kWh
  2. Cost per hour: 0.2 kWh × $0.17 = $0.034
  3. Cost per day: × 10 hours = $0.34
  4. Month and year: × 30 days = $10.20, × 365 days = $124.10

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 Ohio. 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.
