I just noticed that adsense changed it from saying "earnings" to "estimated earnings". Log in and see for yourself... What is the deal with that?
This was discussed before http://forums.digitalpoint.com/showthread.php?t=1609104 It is also on the adsense official blog.
This is the line on the official Adsense blog: "Today we're changing some messaging in the AdSense interface concerning your earnings, and we wanted to give you some more information on why we're making this change. In order to be more transparent about how our system calculates earnings, we've added the words "Estimated" and "Finalized" next to "Earnings" throughout your account. Rest assured these terminology changes don't reflect a change to the way your finalized earnings are calculated. It's simply intended to give you a clearer idea of what's our estimation of your earnings and what's finalized. As you may have noticed in the past, the earnings on the Overview and Advanced Reports pages may sometimes differ from the earnings listed on your Payment History page. This is because earnings on your Overview and Advanced Reports pages reflect initial estimations based on our records. We aren't able to provide finalized earnings on these pages because they still need to be verified for accuracy, a process that takes place a few days after the end of every month. The finalized sum is then posted on your Payment History page by the 10th of the next month. While we can't say how much these amounts would differ for any one publisher, most publishers will not see a significant difference. Again, please keep in mind that this is only a display change, and that your finalized earnings will continue to be calculated and credited to you in the same way as before."
