How Much Does a Basement Dehumidifier Cost to Run? 24/7 Electricity Cost Calculator
If you leave a dehumidifier running in your basement all day, how much does it actually add to your electric bill? The answer depends on more than the wattage printed on the appliance. A dehumidifier may be powered on 24 hours a day without its compressor running continuously. Once the basement reaches the humidity setting you selected, the humidistat can cycle the dehumidifier on and off. That makes the most useful cost equation: Rated Watts × Power-On Hours × Estimated Duty Cycle × Electricity Rate Use the calculator below to estimate your daily, 30-day, seasonal, annual, 5-year and 10-year basement dehumidifier electricity costs. Quick Answer A basement dehumidifier that is switched on 24/7 does not necessarily consume its full rated wattage for all 24 hours. For example, a 500-watt unit powered on for 24 hours with an estimated 60% active duty cycle would have about 14.4 equivalent full-power hours per day. At $0.18 per kWh, that simplified example works ou...
