The Hollywood Reporter says their expectations are even higher, reporting that the three leads could be asking for up to $1 million.
Co-stars Mayim Bialik and Melissa Rauch made the first move, successfully pushing for significant pay raises of $60,000 each per episode, up from their current $20,000-30,000 per-episode paychecks. Their salaries will eventually increase to $100,000 per episode.
Simon Helberg and Kunal Nayyar, who play Howard and Raj respectively, are also likely to negotiate as a unit.
While the large pay raise requests might seem like a lot of money, the success of the Chuck Lorre sitcom has proved a powerful bargaining chip for the series' stars. "Big Bang Theory's" sixth season has been a major ratings success -- -- both on CBS and in syndication on TBS -- and Warner Bros. stands to rake in plenty of cash from advertising revenue.
This is the highest-rated comedy on television by a good distance, and it is also a monster in syndication with Warner Bros. making a ton of money from its various airings across broadcast and cable TV (where it airs on TBS). You may be shocked at the money, but everything is relative, and if we are looking at a gigantic pie here, then the actors deserve a sizable piece of it.
