Lowest Operating Cost: Freezers
Ranked by estimate. Operating cost is an estimate, computed from each model's measured annual energy use at the EIA U.S. national-average residential electricity rate (18.56 ¢/kWh, March 2026). Your actual cost depends on your local utility rate and how you use the appliance.
The Avanti CF24Q0W ranks as the lowest-operating-cost freezer in the dataset, with an estimated annual operating cost of $25.43 based on measured energy consumption of 137 kilowatt-hours per year and the national-average electricity rate. This ranking reflects certified models sorted purely by their energy efficiency costs, without consideration of manufacturer payments or other commercial arrangements.
Operating cost represents only one dimension of freezer selection. Capacity, available features, reliability history, and purchase price are all material factors that influence the overall value proposition of any unit. This energy-efficiency comparison should be evaluated alongside these other specifications and costs to inform a complete purchasing decision.
