About the Electricity Cost Calculator

Electricity cost is driven by how much power a device draws and how long it runs. This calculator converts wattage and usage time into kilowatt-hours, then applies your local electricity rate.

Formula: Cost = (Watts × Hours ÷ 1000) × Price per kWh

Use it to compare appliances, spot energy hogs, or estimate the impact of leaving devices running longer than necessary.
