In the ’90s, Queen Elizabeth (aka the Queen Mother) set up a trust fund for her great-grandchildren. At age 21, Prince William and Prince Harry split the first half of their portion, which totaled around £6 million (about $7.8 million). The Guardian reports that Harry took the majority of the inheritance to “compensate for not becoming sovereign.”
The brothers will split another dividend when Prince Harry turns 40 (later this year). The second installment will be worth an estimated £8 million (about $10 million), though we highly doubt Prince William will be as generous next time around.
Princess Diana also left behind money for her two children. The royal set up a $10 million (after taxes) trust fund for Prince William and Prince Harry, who started receiving dividends at age 25. Forbes estimated the annual checks to be worth around $450,000.
