See, if we talk about the tuition fees, then it is uniform among all the Indian Institute of Technology and is 1,00,000 rupees or 1 lakh rupees for a person with no quota or benefits. The total fees of IIT Delhi and IIT Kharagpur including mess, dining, hostel etc charges is as follows:

IIT Delhi: 1,16,450 (annually with one time components)
