Dear Aspirant, 

The management quota college fees will be same as predicted by the University/college.

However the extra fees in management quota will be in form of donation. 

This donation fees is to secure seat or get admission in the college. This kind of fees varies college to college and branch to branch, merit of students. 

The data is always private and is never out easily. Hence you have to reach the college's fir such data. Usually it start around ₹5lakhs.

Hope this helps. 

Good luck.
