How It Works

Calculate electricity cost based on appliance power consumption and usage time.

An electricity cost calculator estimates the energy consumption and operating cost of electrical appliances. Users specify the power rating in watts, daily usage hours, and electricity rate per kilowatt-hour to compute daily, monthly, and annual costs. The calculator helps users identify energy-intensive appliances and estimate the impact of usage changes on their electric bill.
