Prince William, Duke of Cambridge – $40 million
One of Prince Charles’s heirs, Prince William, Duke of Cambridge, succeeded him as monarch. He didn’t have to wait to sit on the throne before he wanted to get his hands on a large amount of net. Aside from his inherited money, he also received a monthly salary from his job. As a result of his combined earnings from his job and the money he received from British taxpayers, he was able to save up enough money to one day become a wealthy future King of England.
