For example, if your box fan consumes 50 watts and you run it for 8 hours a day, and your electricity rate is $0.12 per kilowatt-hour (kWh): Cost = (50 / 1000) * 8 * $0.12 = $0.048 per day. Keep in mind that this is just an estimate, and the actual much does it cost to may vary based on your specific circumstances.
