About Electricity Calculator

The Electricity Calculator is a powerful tool designed to help you track, analyze, and reduce your energy consumption. Unlike simple estimators, this tool allows you to build a comprehensive list of household appliances, specifying their power rating (in Watts) and daily usage hours. It then applies the standard energy formula: Energy (kWh) = Power (W) × Time (h) / 1000. By inputting your local electricity rate, you get a precise breakdown of costs—daily, monthly, and yearly. Whether you are auditing your home energy usage, planning a budget, or identifying power-hungry devices, this calculator provides the insights you need to make informed decisions.
