How the appliance electricity cost calculator works
Estimate how much an appliance costs to run. Enter its power rating in watts, hours used per day, your electricity price per kWh and days of use.
Energy = watts ÷ 1000 × hours/day × days. Cost = energy in kWh × your electricity rate. The calculator is designed to give a useful first-pass material estimate while keeping the assumptions visible. For a purchase, compare the result with the product packaging or supplier quotation.
Common search terms for this tool include electricity cost calculator, appliance electricity cost calculator, wattage cost calculator, kwh cost calculator. The wording is included naturally so the page answers the same questions people ask when planning a project.
