Multiply the price per kilowatt-hour by the number of kilowatt-hours per day your refrigerator consumes. Based on the average California price per kilowatt-hour of 16.4 cents, a unit consuming 2.4 kilowatt-hours per day would cost 39 cents each day to operate.ivide the wattage of your refrigerator by 3. Your refrigerator cycles on and off, and only consumes the maximum wattage about one-third of the time it's plugged in, according to the U.S. Department of Energy. For a typical 300-watt unit, divide by 3 to get 100 watts before attempting to calculate operating costs.
A simple equation to work out how much running an appliance costs you: Wattage x hours used per day / 1000 = daily kilowatt usage. (1 kilowatt hour = 1,000 watts). As an example, our kettle takes 2,200 watts to run. Assuming that I boiled it (full) for a total of 1/2 hour per day it would use 1.1 kilowatts per day.To work out the cost, multiply the kilowatts per day by the cost per kilowatt hour as per your electricity bill. According to our latest electricity bill, our electricity costs $0.17130 per kilowatt hour.So at 1/2 hour per day, it costs us 19c each day to boil the kettle.ccording to our electricity bill we pay $0.17130 per kilowatt hour, so this appliance would cost us $86 per year or $0.23 per day to run. Apart from the energy rating sticker, most appliances have their wattage printed somewhere on them so you can work out how much they cost to run.
