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.
