Home Energy Appliance Calculator

Welcome to Duke Energy’s Home Energy Appliance Calculator. Once you know how much energy your appliances use, you can make informed choices about how to spend your energy dollar. This tool can help you approximate energy costs for individual appliances and subsequent carbon footprint.

The following costs are based on 10 cents per KWH (taxes and franchise fees not included). Please consider your energy use over the course of a typical month when completing the information below.
