How much is your blog worth?

The recent sale of Career Rambling for $20 000(started in November 2006) reminded me of a tool to get an estimate for a blog. In my case, the only one would be 2012movies.net because the others are branded. So, how much is 2012movies.net worth?

2012movies.net is worth $121,940.64. How much is your blog worth? Using the same tools, Career Rambling is worth $225,816.00(at the time of this post). Based on this, it got 8.8% of the estimated value. In theory, I should get $10 000 for 2012movies.net. Any buyers? ;) It's just a fun tool for you and your ego to try and don't read too much into it. Anyway, the rule of thumb I have seen is about 10 times the monthly earnings. What about your blog?
