Dear Aspirant,

See if you get a seat in NIT , there are fee waivers available in these institutes.

It depends on one's family annual income.

If family annual income is below 1 lakh - complete academic fees is waived off.

If family annual income is below 5 lakh - 66% of total  academic fees is waived off.

Check out detailed fee structures of all NITs here:

Hope this helps.
