I can’t answer your question, but when I was at Google I made a mistake that caused ads serving on Google results to become unclickable. For the postmortem they had me calculate (I don’t think a dollar amount but) the number of ad clicks that would have happened during the time it was down. Of course I looked up average cost per click rates. Not sure if I could share even if I remembered, but it really put things in perspective. Overall it was a good learning experience. I didn’t get reprimanded; several months later I got a promotion.
