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.
Average Wattage. An average 21-cubic-foot side-by-side refrigerator-freezer demands about 780 watts when in operation. Once you know the wattage demanded by your refrigerator, you can figure out how much the refrigerator costs to run.ultiply watts of demand by the number of hours per day an appliance is used and divide the result by 1,000 to get kilowatt-hours. Because refrigerators cycle on and off all day and night, the U.S. Department of Energyâs rule of thumb is to assume eight hours of operating time per day.
