The 42nd president of the United States, Bill Clinton served from 1993-2001. While he was far from wealthy before entering the White House, he certainly made up for it afterwards, raking in $75.9 million (£56.6m) once his presidency ended. Clinton has made a fortune from books, and even held the record (until Barack Obama took it from him) for the highest post-presidency publishing deal.
He received around $21 million (£15m) in today's money for his autobiography, My Life, which was published in 2004 and sold an estimated 2.3 million copies. In 2007, he released Giving: How Each of Us Can Change the World, which also became a best-seller, followed by 2011's Back To Work. His collaboration with novelist James Patterson has also been lucrative, with their first fiction book The President Is Missing, released in 2018, selling over three million copies.
