I very rarely turn my pc off unless I go away on hols and the price is very minimal indeed, dont really notice

I heard it's between 5 and 20bucks a month,depending how you got your power profiles set

i got a 2 bedroom/ 1 bath apartment on the 2nd floor (one more floor above us) and 1 computer running 24/7. There are 2 other computers that run about 12 hours a day and our bill is about $95 USD per month. Since it's getting cooler now, we are trying to save $ by turning the AC off and opening the windows.

get a hell lotta Hamsters on Genterators then cost ya nuffin lol

i leave mine on 24/7

In Aus it costs 1.06cents an hour for a PC with monitor, that's $AU 1.79 a week, so I wouldn't worry too much about one PC, I have 4 running 24/7 and don't notice it
