Thanks to the success of Keeping Up With the Kardashians, everyone in the Kardashian/Jenner family is a bona fide celebrity. They're all rich too.

Kylie Jenner broke records as the world's youngest self-made billionaire. A majority of her wealth can be attributed to the success of her brands Kylie Cosmetics and Kylie Skin, which she heavily markets on social media. Kim Kardashian has her own makeup line, KKW Beauty and a clothing line that with shapewear and loungewear pieces called Skims. Khloe Kardashian is at the helm of a denim line called Good American. Supermodel Kendall Jenner has endorsed many brands including Proactiv, Estee Lauder, and Calvin Klein. Scott Disick has Talentless,  a line of sweats and t-shirts. And then, there's Kris Jenner, the woman who manages it all... and takes that 10% momager fee, of course.

Aside from sharing their own ad campaigns, the Kardashian/Jenner family members get paid to post about the products that they use, just like other social media influencers. Well, except for the fact that they have an insane amount of followers. Combined, the famous family has over 740 million Instagram followers combined. Clearly, there are many people who want to "keep up" with the Kardashian/Jenner family members. That adds up to a lot of influence. This means that they can make some major money on Instagram, even from just one post. The estimated earnings per post were calculated as part of the Myprotein study in conjunction with Inkifi. The numbers are based on each person's follower count and the engagement and authenticity of their followers (bots do not count). Let's take a look at how much each Kardashian/Jenner family member is projected to make from a single sponsored Instagram post.

9. Rob Kardashian- $7.9K per Post

Currently, Rob Kardashian has 1.3 million followers, which is a lot in general, but it is a far cry from the Instagram followers that his sisters have. However, it's really not that surprising. His sisters are way more active on social media, promoting their brands and giving fans sneak peaks at their private lives. In comparison, Rob posts very infrequently and he limits to the content to promoting his sock line Arthur George and his clothing brand Halfway Dead with some pictures of his daughter Dream Kardashian thrown in. He prefers to live his life offline. But, even so, he can still make $7.9K for just one Instagram post. That's not bad for a guy who wants a private life!

8. Caitlyn Jenner- $57.4K per Post
