Electricity Cost Calculator

Electricity Cost Calculator helps users estimate monthly electricity costs for household appliances directly from the browser.

Users can choose from built-in appliance presets or add custom appliances, enter hours of use per day, select a currency and electricity rate, and calculate estimated monthly energy consumption and cost. The extension provides a per-appliance breakdown, total kWh usage, total monthly cost, and a simple formula view for transparency.

It is designed for quick personal estimates and stores settings locally on the user’s device for convenience. Actual utility bills may vary depending on local rates, appliance efficiency, and real-world usage.
