I predict Star Trek IX could earn 500-550 million USD worldwide, of which 300-320 million on US Box Office alone.
Not a chance sadly, the highest earning TREK Movie never came close to those sort of numbers and never will. The stigma of TREK will stop new fans coming in masses and the fickle nature of the fanbase will stop some actual Trek fans from turning up. Not too mention it will be heavily pirated since alot of SCI FI fans are normally tech savvy so know how to get films off the net.
I think ST will make around $100 million in the US and $150 million worldwide, which would net a small but solid enough profit though the DVD's will be key to paramount making more movies at a slightly smaller budget.
With a production budget between 120 and 150 million, if the film only did 100 million in US ticket sales (and another 50 million ww) then this film would be a bigger bomb then Nemesis, financially speaking (even though far more people would have seen it).
Since that budget figure doesn't include ad cost and print cost (which will add at least 40 to 80 million more to the cost of the film) we are looking at best case an expense of 160 million (worst probably 210 million which Viacom would be stupid in the extreme to spend).
And that films typically get only 55% of their ticket sales (rest go to the theatre chains, and that percentage is lower for overseas releases).
That means if it generate WW 150 million in ticket sales, that Viacom would get 52.5 million to apply against their expenses. Meaning a loss at the theatres of $77.5 million dollars. That is greater then the short fall Nemesis had after its horrible theatrical run).
That would leave the home market (primarily DVD sales, followed by rental revenue, then either Blueray sales or tv broadcast rights).
Now on this things get really murky. We don't get figures (at least so far with Trek) for overseas home market data either in sales or rentals). On the US front with declining DVD sales (and rentals) a modest hit for a film is bringing in $50 to $75 million in sales. Lets assume out of that Viacom reaps a profit of 60% (higher margin then most products) that would be about $30 to $45 more million to use against its expenses. And I would guess about another $15 to $20 million off all other revenue streams. That would leave (again on the low end of the possible overall budget, marketing and print costs) $117.5 million against its low end expenses of $160 million. Meaning in overseas sales and rentals it would need to generate nearly $43 more to even break even (not counting things like interest on the costs with loans and such, don't even want to go there).
I would say that with your predictions this film would not even break even, and that is considered a flop. Especially with the amount of the investment.
I think on a barebones level the film needs to hit a WW total of $200 million to be a very , very modest success. $250 million would be a okay.
And I think it means we need a $150 million US gross (which is certainly possible. Adjusted for inflation Motion Picture, Voyage Home, and Khan all did more then 150 million, with Search and First contact coming close to those levels) and 50 to 100 million (more would be nice) overseas.
The motion Picture was able to generate 56.7 million overseas (which is adjusted to over 130 million today), but the rest of original trek sucked overseas (with adjusted dollars not ever even passing 40 million).
Modern Trek (not counting Nemesis which performed in few places overseas to poor results) overseas as done better (then all but Motion Picture) with an adjusted income of $55 to 75 million.
So basically as fans (if we want trek to continue in this form) really are hoping for at the very least the adjusted performance level WW of First Contact (that would break the studio roughly even), but we actually are hoping for the WW adjusted performance of Voyage Home or even better Motion Picture.
If we had the adjusted success of motion Picture we would get a sequel.
