How we worked it out

  1. Energy per hour: 500 W ÷ 1,000 = 0.5 kWh
  2. Cost per hour: 0.5 kWh × $0.18 = $0.09
  3. Cost per day: × 10 hours = $0.90
  4. Month and year: × 30 days = $27.00, × 365 days = $328.50

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 Pennsylvania. 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.
