Electricity Cost Formula
Calculate the cost manually with these steps:
How to calculate electricity cost?
To calculate electricity cost, multiply the appliance's wattage by the hours used per day, then divide by 1000 to get kWh. Finally, multiply by your local electricity rate. This simple formula (Watts × Hours ÷ 1000 × Rate) works for any device, from light bulbs to air conditioners.
