On Home Energy Club, our cost calculator widget helps you to choose an energy plan by performing detailed calculations so you can quickly compare estimated plan costs based on your historic usage data and publicly-available data. Your actual future bill amounts will depend on your future energy usage, which cannot be precisely determined, so the accuracy of plan cost data cannot be guaranteed. You should always read the details of an energy plan’s Electricity Facts Label (EFL) to decide if it’s a fit for your home.

By using the widget, you are certifying that you are the person whose name you have entered into the website and have authorization to access usage data for the address you entered.
