Frequently Asked Questions

Where do the wattage values come from?

We use typical wattage values based on manufacturer specifications, Energy Star data, and industry standards for common household appliances. These are representative averages. Your specific model may draw more or less power depending on its age, size, brand, and efficiency rating.

My appliance is not in the list. What do I do?

Use the universal electricity cost calculator and enter your appliance's wattage manually. You can find the wattage on the appliance's label, in the owner's manual, or on the manufacturer's website.

Do appliances use the same amount of power all the time?

Not always. Many appliances cycle on and off (like refrigerators and air conditioners), so their average power draw over time is lower than their peak rating. The wattage values here reflect typical average draw during use. Appliances with motors often draw a brief surge of extra power when starting up, but this has a negligible effect on your bill.
