Hiii

Since you are asking about sainik school, I would like to tell you that there are many branches in different states and fees structure varries. If you could specify which sainik school are you talking about, it would help me to give a precise answer to your query.
In general the range of fees for sainik school is Rs 1,20,000 to Rs. 1,25,000 for general category students and Rs. 1,15,000 to Rs. 1,19,000 for SC and ST category.
If you specify which state you wish to know about, then i will be able to give you a detailed fee structure for the same.

Hope this helps
Thanks!!
