Others have reported higher already, but for data:

Our team had a bug that cost us about $120k over a week.

Another bug running on a large system had an unmeasurable cost. (Could $K, could be $M)

I would be surprised if half of the user on this site did _not_ create or personally see a bug where a line cost way more than $8000

$1.2mln, gone in about 30 minutes.
