The first couple reported an adjusted gross income of $5.5 million, almost all of it from royalties associated with the president’s two bestsellers: “Dreams from My Father” and “The Audacity of Hope.” The first book — about Obama’s early life and his struggle to find a racial identity — earned about $3.3 million in 2009. The second, a more policy-oriented book, brought in $2.3 million for the president and his family. In 2008, the books together earned them $2.6 million. As president, Obama collected a salary of $400,000, an amount that reflects an increase that took effect in 2001.

Net Worth: $10.5 million
