As a member of the British Royal Family, her finances were intricately linked to the Royal Family's wealth.
She received an annual allowance from Prince Charles, funded by the Duchy of Cornwall.
Upon their separation, a substantial divorce settlement likely included a lump sum payment and potentially ongoing financial support.
She wouldn't have had personal business ventures or endorsement deals due to her royal position.
However, she did inherit some wealth from her family, the Spencers, which likely added to her financial security.
Her primary focus wasn't on accumulating wealth, but on her royal duties and charitable work.
Following her tragic passing, her estate, including jewelry and personal belongings, passed to her sons, Prince William and Prince Harry.
At the time of her passing in 1997 at the age of 36, Princess Diana, renowned for her philanthropic endeavors, possessed a net worth of $25 million as a British princess.
