In the future you may want to consider reading previous posts before making similar ones.

Good luck.

Unfortunately no one here can give you any kind of even reasonably close answer to your question. There is simply no way for us to know.

Even if one of us happened to have a similar site, there are simply to many variables.

The only thing you can do is put AdSense on your site and see how it performs for you. Even then you may well have to spend considerable time tweaking AdSense formats and locations on a page before you find what works best on your site.

if i have 20000 traffic dayly

Is this in hits or unique visitors? Not that we can determine how much you'll make anyway, but I like to know just how optimistic you are for a site you haven't built yet.

In the future you may want to consider reading previous posts as you may find similar discussions. ;)

Good luck.
