Build your appliance inventory. See annual costs. Find the energy hogs. All data stays in your browser.
This calculator builds an inventory of every appliance in your home and estimates the annual cost of each one. It uses the formula: Watts x Hours per Day x 365 / 1000 x Rate = Annual Cost.
Choose from preset appliances (AC, refrigerator, pool pump, etc.) or add custom devices. Enter your electric rate, and the calculator ranks everything by annual cost so you can see your biggest energy hogs at a glance.
Tip: A Kill-A-Watt meter ($30 on Amazon) gives you exact wattage for any plug-in device. The calculator is a close estimate, but real measurements are better.
