This depends on many factors. If you want to know how much your account will cost you within a certain period of time there is a lot to consider.
- daily budget
- quality score
- maximum bid per keyword
There is a nice explanation on the AdWords help pages: http://support.google.com/adwords/answer/1704424?hl=en
If you want to find out how much one click on an ad costs there is another nice and short video about this: http://adwords.blogspot.ch/2009/03/introduction-to-ad-auction.html
