Fees at Polytechnic Colleges in Coimbatore
Polytechnic fees in Coimbatore depend on seat category. Government and government-aided polytechnic colleges charge the lowest fees for counselling-allotted seats, with annual tuition typically ranging from ₹2,000 to ₹5,000. Including exam fees, library and development charges, and other mandatory costs, the total three-year diploma cost at these colleges usually stays between ₹6,000 and ₹18,000. Self-financed or management-quota seats, offered mainly at private polytechnic colleges, cost considerably more: annual tuition generally falls between ₹25,000 and ₹35,000, taking the total three-year cost to roughly ₹75,000 to ₹1,05,000.
On top of tuition, students at both government-aided and self-financed colleges pay additional charges.
