The Big Bang Theory has been renewed for seasons 11 and 12, and the stars are definitely set FOR LIFE.
The top three earners on the show, Kaley Cuoco, Johnny Galecki, and Jim Parsons, have already banked almost $140 million each for 230 episodes; but, even smaller earners like Mayim Bialik have raked in $30 million thus far.
By the way, those figures are just salary. They also receive money on the back end, so they get a chunk of the $1 billion made off of syndication. So even after the show finally calls it quits, the checks will still keep coming.
