What is the price of a live-stream?

Inspired by Underoath's announcement about how they made $800,000 on three live-streams (on tickets, merch, and vinyl), Metal Sucks made some estimates about the price of online shows. According to one industry insider, expenses for one live-stream are: $20,000 for live event production - venue rental, camera operators, live video switcher, lights, monitors, audio mixer; $40,000 - broadcast platform fee (20%); $30,000 - the management (15%). Those estimates can vary, of course, but in a case like this, the band would have made a $20k-$25k profit per show, which is roughly $3k-$4k per band member.
