Throughout its existence, the Grand Slam Cup was famous for paying out the highest prize money of any tournament in tennis. The winner for the first three years of the Cup received U.S.$2 million in prize money, which dipped to $1.625 million in 1993, rose to $1.875 million in 1996 and back to $2 million in 1997 before falling to $1.3 million in 1998. If the Cup was won by a player who had also won a Grand Slam event that year they received a bonus of $1 million. Prize money for the winner of the two women's Cups was fixed at $800,000.
