Also how many blogs do you have? Do you use blogspot, wordpress etc..? Whats your most successful blog?
Depends How much targeted traffic do you have. And it also depends upon which monetizing methods you have implemented on your blog.
I'm using self hosted wordpress blog, easy to setup and more seo friendly than blogger. My earning depend on the traffics and keywords too, sometime earn very well and sometime very low.
if your blog have good contents means. surly will get visitors from major search engines. for example: If your blog have 100 unique contents and 100 backlinks for related those contents means surly you will receive 100*100/10=1000 visitors (max visitors). then your blog have google adsense means surly some good clicks are happen. so you will earn some good money, (as my example you will earn $2- $3 daily) one important thing. the adsense clicks are depends on the country.. for example us peoples likes your content or else some us peoples clicks your ads you will earn ($1- $2) has one click..
Well to be fair my newest project is just 1 week old, but already doing decently with $0.50 a day so far.
I am new blogspot user hence i haven't earned anything till now. but trying to do some quality imrovements
I have recently launched my blog and 5 days ago I installed google adsense on it .With a traffic of 70 people everyday I have got only 1 click in last 5 days

see this is weird thread because it all depends on trends and traffic so you have specify that and there is no guarantee that you surely earn that depends on you advertisements bidding... so there is lot of departments....
One could tell you $523 on average across 37 different blogs. The question for you, however, is how would this information benefit you, as, you've asked the question without any frame of reference...
