The Obamas have made tens of millions of dollars through book royalties. Speaking engagements also bring in millions of dollars.  

In 2006 the Obamas reported income of $916,000. Barack’s second book “Audacity of Hope”, released in October 2006, was a massive hit, selling millions of copies and rocketing the Obama’s income to $4.2 million in 2007. Their income continued to swell in the following years thanks to Barack’s 2008 successful campaign and election. To this day, Barack Obama earns $3.75 for every hardcover copy and $1.12 for every paperback he sells. Royalties remained healthy in 2008, 2009 and 2010.

In February 2017, Barack and Michelle Obama received a $60 million advance for the combined rights to their autobiographies.

Former President Barack Obama and Michelle Obama have purchased a seven-bedroom, nine-bathroom home in Edgartown, Massachusetts, according to reports. The price for the 29-acre estate was $11.75 million, public records show.
