It depends on your will, and if you have the will to earn some money with adsense, then the amount you will make will depend on your website creation knowledge, then if you make a website, your daily adsense revenue will depend on the number of clicks, but since number of clicks depend on the number of people that visit your site your revenue will depend on the traffic you get to the site, and when you get the traffic your adsense revenue will depend on how much clicks will you get, and that will take some experience and time to adjust the right ads.

Do you actually use this stuff? But I would say it depends on the audience too, webmasters tend to be more adblind than any other type of audience, so certain niches may not pay as good. Traffic, targetted traffic, good ad placement and content - that is what I would say makes the perfect blend for dollar .
Junije, that's a pretty mad answer to a very often asked question, but at least you put some thought into it instead of repeating just about every other answer. No one is really going to answer this because there is no true answer, it's just like nearly every other job - the more work you do the more you get back. Really there are at least two ways you can go - have lots and lots of websites, filling up at least one dedicated server, and you can make a good living out of it. Or make one or two mega huge sites that are very popular. To do either properly will take you years, but it is doable to be earning $100+ a day for most people if they really obsess about it, and much more if you're quite lucky.
