What we know for sure is overall it costs slightly more to hh a tier 1 dino than it would be to hatch two tier 0's, raise them, and fuse them. It's costs about 500 more coins but there are significant times savings.

Exactly calculations have not been done past tier 1 so far, but I think it's a fair assumption to assume there are cost savings to go along with the more significant time savings.
