According to the analysis of Paypal tax documents (which can be accessed at this link ) carried out by Radar, a chunk of that income comes from her eBay charity auctions. Radar worked backward from the amount received in 2013 by Life Change Community Church, a religious organization founded by Kims own mother, Kris Jenner. That figure was $44,917. But Kim herself has said that she donates 10 percent of her earnings to charity, and other money comes out of the total as well. When the eBay numbers get broken down, the auction management agency that posts for me gets a percentage for all their hard work, the 33-year-old said last year . Then, eBay listing fees, end of auction fees, eBay Store fees, Paypal fees, etc., all add up to about half the sale. Then I give 10% to charity. Using that information, Radar calculated that Kim Kardashian pocketed more than $404,000 from her charity auctions on eBay last year.
