Read the yellow label attached to the front or side of your new refrigerator. All fridge labels include their annual kWh. Then consult your monthly utility bill to determine how much your local utility company charges per kilowatt. Multiply this number by your fridge's annual kWh, then multiply by 8765.8. The total is the estimated cost of operating the fridge for a year at your current utility prices.

Contact your refrigerator's manufacturer. Notify the customer representative that you wish to calculate a refrigerator's annual kWh. The representative will ask for the refrigerator's model number, which will be noted in the owner's manual as well as on the white label on the back end of the fridge near its power input. The representative will then be able to provide you with the annual kWh for the appliance.
