Our happy hour fact to amaze your drinking buddies with.

John F. KennedyJohn F. Kennedy and George Washington were our two richest presidents by far.

The Atlantic magazine took into account property, savings, salary, inheritance and royalties when calculating, in present dollars, how much each of the 43 men who have been president were worth at their peak. JFK, due to family money, was valued at a whopping $1 billion, whereas George Washington, who had massive land and slave holdings, checked in at $525 million.

Other presidents who topped the $100 million mark were Thomas Jefferson ($212 million), Teddy Roosevelt ($125 million), Andrew Jackson ($119 million) and James Madison ($101 million).

Barack Obama is currently worth $5 million. That number, however, will likely skyrocket when he leaves office.

Bill Clinton, for example, has already upped his net worth to $38 million -- and the big fella never even did that lucrative McDonald's ad campaign we all expected him to cash in on.
