11:11 PM PT -- An industry source tells us Kim actually pulls in $1 Million per Instagram post ... and it's likely her legal team will re-file the docs with an adjustment.
Kim Kardashian just filed legal docs revealing just how incredibly powerful and influential she is ... and that power and influence translates into insane cash.
Kim is embroiled in a lawsuit against Missguided USA clothing company, a fast fashion brand. She claims the company used her image to hawk its wares. The company apparently didn't respond to her claims, and she's now going in for a default judgment for $5 mil.
That's not why we're telling you about this. In the docs, Kim justifies the $5 mil by explaining her capacity to make big money. She says she gets between $300,000 and $500,000 FOR A SINGLE INSTAGRAM POST!!!
And, get this ... in the docs, she says she frequently turns down offers for that kind of money because she doesn't want to be associated with the brands.
As for the lawsuit, Kim says her brand is being damaged by Missguided USA associating itself with her.
It's no secret ... Kim can literally make a business by giving it a thumbs up. It's like Oprah, only arguably bigger.
