Have you seen VFX of Kesari? It's low grade pathetic. Anyways, Kesari has only one A-Lister i.e Akshay and director is no one. CoP would be 60cr at max with that pathetic production value.
Tanhaji 175cr is right. Only Ajay and Saif have decent fees.
In budget, the biggest factor is Actor's fee.
2.0 budget was close to 600cr due to 3 big fees. Rajini took 50-60 while Akshay was 40 and Shankar had 60-75cr iirc.
