How the Appliance Energy Cost Calculator works
Add each appliance with its wattage and daily usage hours, plus your electricity rate. The calculator converts each into kilowatt-hours and shows the daily, monthly, and yearly cost to run them.
Frequently asked questions
Where do I find an appliance's wattage?
Check the label on the appliance itself, its manual, or the manufacturer's website — it's usually listed in watts (W).
Where do I find my electricity rate?
Check a recent electricity bill — it's usually listed as a price per kilowatt-hour (kWh).
