Why Simon helberg gets paid more than kunal nayyar in the big bang theory And why is there such a big salary gap between the top 3 and these 2?

Simon Helberg likely earns more than Kunal Nayyar due to differences in their roles and the dynamics of the show's contracts, with Helberg's character, Howard Wolowitz, often being a central figure in storylines. The significant salary gap between the top three cast members (Jim Parsons, Johnny Galecki, and Kaley Cuoco) and Helberg and Nayyar can be attributed to their established star power and the negotiating leverage they had, which stemmed from being the show's primary leads. As the series progressed, the top three actors became more integral to the show's identity, justifying their higher pay.
