This is despite her having little success on the tennis courts as she has been plagued with injuries and a run of first-round exits since her historic win at Flushing Queens.
The sixth spot in the world earnings is a whopping 180 places above her WTA World Rankings.
The list does have its absences and no longer features retired player Roger Federer, even though he is estimated to have won $95 million (£75.5 million) in the past 12 months.
Leading the list is Novak Djokovic who has earned a total of $38.4 million (£30.5 million). He is closely followed by his latest rival Carlos Alcaraz with $31.4 million (£25million).
Ahead of Raducanu on the list are Iga Swiatek, Daniil Medvedev, and Spanish legend Rafael Nadal.
It might be a surprise to some that Raducanu has earned so much despite her poor performance in the years after her Grand Slam win and also since she has not been active in the past four months.
But the Forbes list does not only focus on prize money but also looks at earnings from deals outside tennis.
The young player has a lot of brand deals and they offer a lot in terms of earnings. She is currently sponsored by Dior, Tiffany, Evian, British Airways, Porsche, Wilson, Nike, HSBC, and Vodafone.
