The first year at NIFT is the foundation year in which you spend around Rs 1,000 each month on stationary and other materials. In the second year you go to your respective departments (example: fashion design, accessory design, fashion communication) and the expenditure varies from course to course. In fashion designing, there's no limit to the expenditure on fabrics. The fabrics range from 100rs/meter to 2000rs/meter. So to give an estimate on the expenditure is actually not possible. It's completely upto the student and his taste.

It totally depends on the brand name of your B-School and the efforts put in by you. Internship quality also matters a lot.
