a laptop will use between 60 and 120 watts and a desktop typically between 100 and 200 watts (not including the monitor and other peripherals).

so to leave a laptop on 24/7 for a month would cost 14-30 cents per day and 4-8 dollars a month. Based on 10 cents per killowatt-hour. you can double these values for a general idea on your desktop power consumption, plus some for your monitor.

As a guess: 20-25$ a month for a typical computer that is on 24/7.
