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.
