How to estimate dehumidifier correctly
The 500 W and 10 h/day values are an editable example, not a claim about every model. This appliance is best treated as continuous or recurring use.
What to verify
Check the rating plate for input watts and use a plug-in energy meter when the appliance changes power during operation.
Formula
Power (W) ÷ 1,000 × active hours × electricity rate. This example uses 5 kWh/day, 150 kWh/30 days and 1,825 kWh/year.
Accuracy limit
The calculator prices the values you enter. It cannot know thermostat cycles, power modes, losses, appliance condition or the exact tariff on your bill; verify those inputs for a decision.
