How do I calculate the cost of running an appliance?
Multiply the power in watts by hours used and divide by 1,000 to get kilowatt-hours (kWh), then multiply by your price per kWh. This calculator does it for a day, month and year automatically.
Where do I find an appliance's wattage?
On the rating label (often on the back or base) or in the manual. If only volts and amps are listed, multiply them to get watts.
What uses the most electricity at home?
Heating, cooling and anything that runs constantly — electric heaters, air conditioning, water heaters and older fridges — typically account for the largest share of a bill.
