As one of the main stars of the series, Kunal Nayyar pocketed quite a large salary during his time on "The Big Bang Theory." According to Screen Rant, the actor had a starting salary of $45,000 per episode. This was reportedly the same as his co-star Simon Helberg, and both would end up earning around $150,000 an episode during the show's second season. This increased even more during the later seasons, finally settling at a whopping $600,000 per episode.

This rate differs slightly from Celebrity Net Worth's estimation, which puts Nayyar's final salary at $800,000 per episode. Regardless, Nayyar — and Helberg (via Celebrity Net Worth) — were earning more than a comfortable amount during the show's run.

Maybe not as much as their other co-stars, though. Jim Parsons became the highest paid TV actor in the world in 2017, according to Forbes, earning $1.2 million per episode toward the end of the series. In comparison, Johnny Galecki reportedly ended up earning $1 million per episode (via Screen Rant), and Kaley Cuoco finished the show earning $900,000 per episode.
