Hi aspirant
You need to atleast 6-7 lakhs and it vary from college to college .Check the fee structure of IITs here: https://engineering.careers360.com/articles/iits-btech-fee-structure
But when you are at IITs you can easily get education loan form any of the banks in India.
If you are in any private college you need more than 5 lakhs.And it depends on college to college .
Hope this was helpful.
