A single episode of Big Bang costs approximately $9 million nowadays.
Considering the price of producing a season of Big Bang Theory, CBS may really struggle to pay the bill without the extra revenue from increasing syndication.
With stars Johnny Galecki, Jim Parsons, and Kaley Cuoco pulling in a whopping $1 million per episode and even supporting players Simon Helberg and Kunal Nayyar earning approximately $900,000 per episode, the cast salaries alone could be enough to discourage CBS from wanting to continue the series.
The actors’ contracts will be up as of the end of Season 10; renegotiations may mean that CBS will face demands from the cast for even higher pay.
