Frank Spadafora-founder of D'Marie Archive, an analytics group that recently introduced an app that evaluates the social power of different celebritiestells CR Fashion Book that the three most highly ranked supermodels on social media are Kendall Jenner, Cara Delevigne and Gigi Hadid.
They "are currently valued between $125,000 and $300,000 for a single post across their portfolio," he says, adding, "If you want to reach a model's audience, you're going to have to pay a hefty additional fee for that."
To put that in perspective, the average millennial woman makes somewhere around $31,069 a year, according to Business Insider.
Thus, Gigi makes a little over nine times as much per single Instagram post.
