Most of the wealthiest presidents were prosperous before making the White House their office, with this money helping them accomplish their presidential ambitions. Some, such as Herbert Hoover, worked hard to develop an empire, while others, including Theodore Roosevelt, inherited their fortune.
The wealthiest president by far is 45 — Donald Trump. Serving from 2017 to 2021, Trump was worth around $3.7 billion before he took office, according to Forbes.
