Power Consumption Calculator – Calculate Electricity Usage & Cost

A power consumption calculator helps you estimate how much electricity your appliances use and how much it costs. It calculates energy in kilowatt-hours (kWh), which is the standard unit used in electricity billing.

The formula used is: Energy (kWh) = Power (W) × Time (hours) ÷ 1000. This helps convert watt usage into kilowatt-hours for billing.

For example, a 1000W appliance used for 1.5 hours consumes 1.5 kWh. If your electricity rate is ₹8 per unit, the cost will be ₹12.

This calculator is useful for homeowners, electricians, and businesses to monitor energy usage, reduce costs, and improve efficiency.
