Frequently Asked Questions
How do I find an appliance's wattage?
Check the label on the appliance itself (often on the back or bottom), the user manual, or a wattage rating sticker — many appliances also state amps and volts, which you can multiply together to estimate watts.
What is the difference between watts and kilowatt-hours?
Watts measure instantaneous power draw, while kilowatt-hours (kWh) measure energy consumed over time — kWh is what your utility actually bills you for, which is why this calculator converts watts and usage time into kWh.
Which appliances typically cost the most to run?
Heating and cooling systems, water heaters, clothes dryers, and older refrigerators are typically the highest energy consumers in a home, often dwarfing the cost of smaller electronics and lighting.
