I don't know, but it will include...
A million for each main voice actor
$100k for supporting actors
Orchestral score (not many people can do those)
$50k per licensed song
Work on the "game engine" that supports the film (each film used to break technical ground... Fur in monsters Inc, hair in the Incredibles, etc)
Motion capture, clay modelling, 3D modelling, rigging, animating... everybody needs a studio quality machine and display...
The only thing I feel confident isn't a big chunk of the cost is the actual rendering.
