Energy-Efficient Models. An energy-efficient large freezer with more than 25 cubic feet will use about 956 kilowatt-hours per year, according to EnergyStar.gov. That equates to about $10 a month. When you reduce the size of your freezer, your costs go down. Standard freezer sizes run between 19 cubic feet and 22 cubic feet. Monthly costs for these units average about $67 per year or a little over $5 a month.
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.ecause 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. If your refrigerator demands 780 watts, multiply 780 by eight hours to get 6,240 watts per day.
