Find out exactly how much it costs to run any appliance in your home.
The cost to run any appliance depends on three factors: its wattage, how many hours you use it, and your electricity rate. The formula is:
For example, a 1,500-watt space heater running 4 hours per day at $0.13/kWh costs (1500 x 4 / 1000) x 0.13 = $0.78 per day, or about $23.40 per month.
Here are typical wattages for common household appliances: a window AC unit uses 500-1,500 watts, a refrigerator uses 100-400 watts, a clothes dryer uses 2,000-5,000 watts, a gaming PC uses 300-600 watts, an LED light bulb uses 7-15 watts, and a phone charger uses 5-20 watts. Check your appliance label or manual for its specific wattage.
