Hello,
The fee structure of CSE branch varies from college to college..
Let's talk about cheapest and best engineering college in India for CSE :-

In IITS and NIT's , you can get 100 % remission on your tution fees if your Annual Family income is less than 1 lakh.

You can get 2/3rd rebate on tuition fees if your family income ranges between 1 lakh and 6 lakh.

Provided you must have income certificate .

If you belong to ST/SC category then you will get full remission of tution fees .

But other colleges which have low fees in comparison to others are.

1) Jadhavpur University (West Bengal ) One of the best and cheapest college . Placements are also excellent here . Fees here is very very low affordable to everyone . NIRF rankings 13 .

2) Zakir Hussain College of Engineering (Aligarh Muslim University) NIRF rankings 35 , one of the best & cheapest college for engineering .

3) Jamia Millia Islamia (New Delhi) Very good college for engineering with very affordable fees structure .

4) College of Engineering , Guindy (Chennai .) Very old , reputable and good college with excellent placements statistics.

5) Indian Institute of Space Science and technology . ( Thiruvananthapuram) . You just have to pay admission fees once which is around 60000 I think. After that if you score above 7.5 cgpa (for general category , other categories have other cutoff) , then you will not have to pay fees for next semester . This college is fully funded by ISRO. Also some of the students are absorbed by ISRO in placements.
