So, the most it can cost you to run a ceiling fan without lights is about $126 per year, which is equal to about $10 per month and the least it will cost you is $19 per year, which comes out to just $1 per month...which in either case, is amazingly cheap.s you can see, the calculated cost to operate the fan with lights off is only $0.0029/hr. If you re-calculate it with the lights turned on, the cost increases by about 300% to $0.0091, but is still less than a penny per hour.
The wattage of the light fixture can have a much greater impact on the cost than the motor. When calculating the cost to operate a fan with the lights on, you must add the wattage of the lights to that of the motor. The range of wattage for a ceiling fan light fixture is anywhere from 13 watts to 190 watts.alculating the cost to operate a ceiling fan is a simply a matter of knowing how many watts the fan uses and multiplying that by the cost per kWh of electricity you are being charged by your utility company. This will give you the cost per hour to run the fan.
