The cost for the average ceiling fan to run all day on low power will be about five cents a day. However if the ceiling fan is rather large or if it is on high power the usage may be more.
The cost of running a ceiling fan is far less than the cost of running an air conditioner. Keeping the fan running lowers the body temperatures of the people in the room and saves money.
Running a ceiling fan cost just as much as running a air conditioner. Especially it they run all day and night, non stop. It was around 20 bucks a month to run ceiling fans in your house. The more you have the more it will cost. We have a engery saver on or central air.
A fan uses 55 to 100 watts at a time, depending on its size (smaller fans use less electricity). Electricity rates vary from state to state. The average in the US is 12 cents per KwH. So, for every hour the fan runs, it uses 0. 055 to 0. 1 kW and costs between 0. 0066 and 1. 2 cents.
It is pretty inexpensive to run your ceiling fan. I currently run mine all the time as well and it might have and effect of a dollar or 2 but is nothing huge.
