The cutoff changes every year and Nobody can exactly predict the real cutoff. Many of the coaching Institute predict the cutoff of jee main 2018 which you can check from the below link. But by clearing cutoff you are only eligible for jee advance exams. It does not have any connection with getting seat in NITs.  You need more marks than cutoff to get seat at NITs and other top institutions. 

Go through this link to know about predicted cutoff by various coaching Institutes:-
