Ceiling fans use less than 100 watts on average when turned on at high speed. The actual number of watts used differs among ceiling fans depending on the size and number of blades, the brand and the type of motor.
If we figure that our energy costs are ten cents per kilowatt (your cost may be different), and that the fan uses 77 watts of energy on medium, we can do the calculation as follows. 10 hours x 77 watts = 770 watt hours or .77 Kwh. At a cost of ten cents per Kwh your daily cost to run a fan would be 7.7 cents a day.
