Bill Clinton and Hillary Clinton are among the most intriguing of politicians when it comes to net worth. The couple did not come from rich families and Bill Clinton was a career politician until he left the White House in January 2001.

"When we moved into the White House, we had the lowest net worth of any family since Harry Truman," Bill Clinton famously said.

Legal fees even put the couple in the red after Bill Clinton left office. "We came out of the White House not only dead broke but millions of dollars in debt,” said Hillary Clinton.

But the Clintons quickly gained ground to substantially raise their net worth. In 2015, Forbes noted that in federal filings that the couple was "worth somewhere between $11 million and $53 million."

While Hillary Clinton was running for the White House in 2016, tax returns showed that the couple had pulled in $240 million since 2001.

The bulk of the $240 total, $189 million, was made by Bill Clinton, through speeches, books and consulting work. From writing books, he made approximately $38 million, according to Forbes. Consulting for two non-profit organizations and an investment firm paid $39 million. Making speeches brought in the bulk of the income.

The Clintons paid $95 million in taxes from 2001 to 2014.

In 2013 and 2014, Hillary Clinton earned $9 million a year by giving speeches and from 2013 to 2015, she was paid $14 million by Simon and Schuster for her book " Hard Choices ." During her tenure in the Senate from 2001 to 2009, and on President Obama’s cabinet from 2009 to 2013, her income from outside pursuits was relatively small. Hillary Clinton earned $186,600 per year as Secretary of State.

The couple's main source of income has been from speaking engagements. Since 2001, and up until Hillary Clinton began her presidential campaign in 2015, the Clintons were paid over $153 million for making speeches, according to CNN. Each one of their 729 speeches had an average fee of $210,000. Bill Clinton’s portion of the total speech earnings was slightly over $132 million from 637 speeches, and Hillary Clinton made a little over $21 million from 92 speeches.

Hillary Clinton's 2008 presidential campaign cost the couple $13 million.
