John F. Kennedy's net worth when he died was an estimated $1 million. This may seem like a lot of money, but it is actually quite small in comparison to other presidents' net worths. For example, Bill Clinton's net worth is estimated to be around $80 million and Donald Trump's net worth is an estimated $3 billion. Kennedy's relatively small net worth can be attributed to the fact that he was only 46 years old when he died and had not yet had the chance to amass a large fortune.
