It's believed the budget for fans have to wait until 2021 to see the Snyder Cut on HBO Max. There's no denying the Snyder Cut exists, but it isn't complete yet.
Following the official Snyder Cut announcement, it was revealed the original crew was reassembling to handle their various post-production responsibilities, which isn't going to be a cheap proposition. At the time, it was said the Snyder Cut budget would be between $20-30 million, but it apparently is going to cost a lot more than that.
Chairman of WarnerMedia and HBO Max head Bob Greenblatt appeared on the Recode Media podcast to discuss the new streaming platform. When asked about the Snyder Cut, Greenblatt elaborated on the process and what it's going to take for the Snyder Cut to finally be ready to air:
"It isn't as easy as going into the vault and there's a Snyder Cut sitting there to put out... Zack is actually building it and it's complex, including - and I don't wanna get into too much detail that we haven't already talked about yet - but, new effects shots. It's a radical rethinking of that movie and it's complicated and wildly expensive. Which is, of course, a number I won't quote... I'll just say I wish it was $30 million and stop there."
This is one of the reasons why some were doubtful the Snyder Cut would ever see the light of day. the Release the Snyder Cut movement was so important throughout this whole development. Seeing the fans clamor for this version (and of the Justice League cast chip in) was what encouraged WB to reach out to Snyder and strike a deal. The Snyder Cut will now be one of HBO Max's flagship programs when it comes out, convincing more people to subscribe.
In addition to finalizing a plethora of VFX shots and completing the musical score, the budget may also cover extra work from the cast. Reportedly, the actors will return to record new dialogue so the film can be finished. It'll be interesting to see if a final financial figure is ever reported, or if the real cost to Release the Snyder Cut will forever be a mystery. Since this version of Justice League is bying theaters and won't rely on ticket sales to turn a profit, the studio may decide to just keep that information secret.
