The data behind this page
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. The full Freezer category page shows all 658 freezers ranked by cost; the state-rate guide covers the half of this number that isn't the appliance.
