Jerry is clearly the most talkative of the group, although his lines also declined as the seasons progressed. Cosmo Kramer, on the other hand, played a bigger part in the sitcom as the show went on. George Costanza and Elaine Benes seemed to contribute evenly throughout the show's nine-year run.
What about compensation on a per-line basis? In the final season, Jerry Seinfeld made about $13,000 for each line he delivered. Michael Richards (Kramer), who delivered the least lines but was paid the same as the other two supporting characters, made almost $15,000 per line, while Jason Alexander (George) and Julia Louis-Dreyfus (Elaine) made about $11,000 and $13,000, respectively.
Seinfeld's per-line payday was doubled between the eighth and ninth seasons, while the other characters saw their compensation triple.
Seinfeld, however, had an additional source of income that the others didn't. As one of the show's creators, he gets a cut of the show's lucrative and ongoing syndication deals, which are estimated to have brought in over $3 billion since 1995. Seinfeld's cut comes to about a whopping $400 million over that time period.
Even if we only count the seasons for which we know Jerry's salary, that means that "Seinfeld" has earned him at least $440 million, or about $30,000 for every line he ever delivered on the show.
