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.
