Yesterday at about 3:30pm (EST) Google changed the AdSense console overview page to show the word "estimated" by "Today's Earnings." So now it reads, "Today's estimated earnings" instead of just "Today's earnings." A WebmasterWorld thread was started to ask questions about this change, and then the Google AdSense Blog confirmed the change.
Here is a picture highlighting the change:
Google explained:
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.
