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.
