Firstly,may I know the stream you have chosen.As there are many government and private colleges. Also, kindly specify the location where you are looking for a college. Fees depends on the college's education quality, infrastructure, faculty members and management. If you talk about Science stream then private colleges can cost you 10,000-1,00,000 per year. For government colleges fee will be nearly upto 25000 per year or less. Commerce and arts streams can cost you about 10k-40k(Depends upon the college and location).Also, when you opt for special subjects like computer science in science stream, then the fees are a bit more.
Hope this helps!
