Electric Appliance Calculator — Help and Information

Computer (awake)

"Computer (awake)" is the amount of time that your computer (including monitor) is turned on and not in "sleep mode". For example, if your computer is on at full power for 5 hours a day, please enter "5" in the first field and select "hours/day" in the second field. Your cost per month and cost per year will be automatically calculated.

Many computers are equipped with energy-saving features that put your computer to "sleep" after a period of inactivity. To calculate this cost, please use the "Computer (asleep)" section.
