What is the average wattage of a 10 cubic foot refrigerator?

The average wattage for a 10 cubic foot refrigerator typically ranges between 100 to 400 watts. However, this varies based on the model, energy efficiency rating, and whether it’s a top-freezer, bottom-freezer, or side-by-side design. Older models generally use more electricity due to less efficient technology and insulation compared to newer, ENERGY STAR-rated refrigerators.

It’s also important to note that the wattage reflects power usage primarily during the compressor’s active cycles. Since compressors do not run continuously, the actual power consumption may be lower when averaged over a 24-hour period. Calculating the refrigerator’s energy consumption will provide a more accurate picture.

How can I calculate the energy usage of my refrigerator?

To calculate the energy usage of your refrigerator, you’ll need to know its wattage and how many hours it operates. You can usually find the wattage on the appliance’s specification label.
