This translates to about 0.150KW. If you have a light bulb in the fan then that is about another 0.060KW for a total of about 0.210KW for the fan and light. Around my area, power is about 9 cents per KWH. Multiply the usage by the rate to get the total cost.So the cost to run the fan in my area would be ($0.09/KWH * 0.210KW * 1 hour = $0.0189).Source(s): Justin Â· 6 years ago.round my area, power is about 9 cents per KWH.
