That's £37,000
per episode (or close to $50,000 US dollars
per episode) for her role as Rachel Zane in Suits. This means she earned £333,000 per year (or approaching $450,000 US Dollars). That's close to one half million a year.
I'm impressed! Given Meghan's status as an 'unknown' that is fabulous money! [However, by my tally she was making far more than that for Suits, well over half a million per annum, and add to that her side gigs promoting fashion lines, etc, she could easily have been clearing $1 million a year imo, making the $5 million net worth conservative. JMO]
I think people are gauging money by celebrity status which really ratchets up the numbers, especially in a wildly popular show. Suits was a very respectable show (7 seasons is a successful show) and I would assume what Meghan was paid steadily increased as the show wore on and her character became integral to the show. We don't know when she was making the sum indicated (or if it's even the true amount). Personally, I would be more than pleased to be making that sum of money, at her stage in her career, as it then was. Just saying.
