Fury makes the first defence his WBC heavyweight title against Wilder and will take home £18m – before deductions for taxes and training and management costs.
The Brit grew his net worth to £40 million last year when stopped Wilder in their rematch.
The win marked the start of Fury’s second reign as heavyweight champion after first won titles against Wladimir Klitschko in 2015, later vacating them due to inactivity.
Although Fury will pocket another eight figures for his trilogy with Wilder, the Brit missed out on a bigger payday against Anthony Joshua this year.
Fury and Joshua were signed to fight in August, but an arbitration judge ruled in favour of Wilder’s trilogy against ‘The Gypsy King’.
The highly anticipated fight between the two British rivals was scuppered last month after Joshua lost his heavyweight titles to Oleksandr Usyk.
Fury admitted that he was rooting for Joshua in the fight and his loss meant a £75 million payday for Fury went “down the toilet”.
He told iFL TV: “It was a bit of an anti-climax, no part of me was happy that he lost. We were all in the front room saying ‘come on win the fight, land a big right hand’.
“Why would I be pleased, there just goes £75million down the toilet so you know I wasn’t pleased that he lost. I was actually wanting him to win, and I always want him to win.”
Joshua became Britain’s first £100m boxer earlier this year and added to that hefty figure with a £15m payday for his loss to Usyk.
Financial records filed last year showed Fury’s bank balance at just over £40m, up from £6.6m the year before.
The accounts were filed up until March 2020 and covered Fury’s 2019 fights against Tom Schwarz and Otto Wallin, his WWE debut against Braun Strowman and his stoppage win over Deontay Wilder.

But Fury played down fighting for belts and money, insisting his only goal in the ring is to survive.
He told ESPN: “I said before I beat Wladimir Klitschko, it wasn’t about the belts. Wasn’t about being remembered. I actually fight for crazy reasons. I’m not fighting for glory right now.
“People say when you make a lot of money, you don’t fight for money anymore. You fight for glory and all that, but I’m honestly not fighting for glory because I don’t care about glory.
“It’s short-lived, and I ain’t fighting for money. I have to just revert back to the same thing again. I’m just fighting to survive. If you don’t fight in your life, no matter what job you’re in, you’re going to die. That’s it.
“Whether it’s physical, mental, emotional, there’s going to be a fight. Someone has to do it, and I’m glad that someone’s me, rather than someone else in my family.”
