The expert financial snoops over at Celebrity Net Worth have pored over the years of news reports about the estate Prince left behind, and what they’ve come up with still covers a pretty wide range. They calculated his net worth at the time of his death to be anywhere from $200-300 million. That’s quite a difference from the initial $83.2 million valuation from years before.

Even for a pop star, that’s quite a bit of cash. In fact, the sizable estate Prince Philip left behind — just $30 million — pales in comparison to the singer’s fortune. And he was an actual prince! So how, exactly, did the singer manage to rack up so much cash? Celebrity Net Worth explains that Prince held near complete ownership of his work, which included the publishing rights to his songs and the rights to his likeness. That’s something not all pop singers can boast about. He also owned several properties, including 149 acres of land in a suburb of Minneapolis, where his home and recording studio, known as Paisley Park, are located. According to The New York Times, the IRS is demanding another $32.4 million in taxes from 2016, and another $6.4 million as a penalty for all the alleged errors in the valuation of his estate. Comerica has said it wants to take the matter to the courts, and the issue remained unresolved even five years after Prince’s death.
