President Obama and first lady Michelle Obama made slightly more than half a million dollars in 2013, according to the president's just-released tax return.
The Obamas made just more than $503,000 and paid about $98,000 in taxes.
About $104,000 of the Obamas' income came from the president's books, which have been a chief source of income during his presidency. Obama's salary is just less than $400,000.
The Obamas' income has dropped steadily in recent years, from $790,000 in 2011 to $662,000 in 2012 and now half a million in 2013. A big reason is that he is earning less money from his books.
Vice President Biden and his wife, Jill Biden, meanwhile, made a little less than $409,000 in 2013. They paid $96,000 in taxes.
Jill Biden made $24,000 from her book writing.
