Forbes:
From its May 2017 release through the end of the year, Trump’s book Women Who Work sold 31,900 copies, according to data from NPD Bookscan, which tracks 85% of the U.S. domestic book market. That means the book, which advises women on how to excel in both their social and professional lives, has raked in about $1.1 million. Portfolio received an estimated $566,000 from all the sales, while it paid a $787,500 advance to Trump prior to her joining her father’s administration as an advisor. The First Daughter will receive another installment of her advance in the upcoming months. Altogether Forbes, with help from publishing experts, estimates that Portfolio, which did not respond to multiple requests for comment, has lost at least $220,000.
