[4] Estimated net worth of $1.3M, according to Money magazine, December 2007. See also Henry Blodget, "Barack Obama and His Money", Slate, 13 March 2007: "According to Obama's most recent public financial statements, he and his wife, Michelle, were worth between $500,000 and $2 million at the end of 2005 (excluding whatever equity they have in their $1.65 million Chicago house)." Presumably much of this is from pre-tax royalties of $1.2M for The Audacity of Hope. None of Obama's wealth is inherited. The Obama family's 2007 tax returns indicate a combined income of $4.2M, nearly all from book royalties. They paid $1.4M in federal taxes, with donations of $240K to charity.
