Freezers use less electricity when they run than other appliances, such as your clothes dryer. However, your freezer runs all the time and uses more electricity than most appliances per month. How much power your freezer uses in a month is related to its wattage and how efficiently you use it.

Freezer wattage generally varies depending on the size of the freezer. For instance, a 20-cubic-foot standalone freezer uses 350 watts, while a 15-cubic-foot freezer uses 335 watts, according to the Otter Tail Power Co.

Refrigerator-freezer combinations are more common in homes than standalone freezers and they also have higher wattage. Side-by-side refrigerator-freezers, which are typically between 22 to 26 cubic feet, use up to about 780 watts.

Electricity Cost

Otter Tail estimates that you use your freezer for a median of 300 hours per month. This translates to 100.5 kilowatt-hours of use for a 15-cubic-foot freezer, 105 kWh for a 20-cubic-foot freezer and about 234 kWh for a side-by-side freezer. At the time of publication, electricity companies charge an average of 11.64 cents per kilowatt hour, so the monthly cost of running a freezer is $11.70, $12.22 and $27.24 respectively.

Using Less Electricity

Older freezers can use 110 percent of the energy that a new, energy-efficient model uses, so you can use less electricity by replacing yours with an Energy Star-certified model. According to Energy Star, you can also save energy by keeping your freezer full. This way, there's less air for it to chill.
