Hello Aditya,

To become a commercial pilot at first you should have a CPL or commercial pilot licence . basic basic minimum eligibility criteria is that you should have minimum 55% marks in your 10 plus two level with physics chemistry and mathematics in aggregate. At first to become a pilot you have to complete your flying training from a Directorate General of Civil Aviation certified Institute. After leaving the flying Institute you should have minimum 250 hours flying experience to be eligible for commercial pilot licence. Also you can gain this experience while in your flying School. You will get the complete trainings.

To complete all of this process it should require about 45 to 60 LAKHs  in general. Among them only 30 to 40 lakh is for the commercial pilot licence and rest is for type rating, which is just a training or experience where you will be certified that you are eligible for a particular aircraft.

Hope this will help you
