Hello Aspirant,

Salary-wise when you see, CA would be a better option as after clearing the final exam and becoming a certified chartered accountant authorized by ICAI (The Institute of Chartered Accountants of India ) , the starting salary would be approx. 7 lakhs per annum. Upon getting yourself placed at reputed firms or clients , as you gain experience , the salary will also increase. M.Com and M.Sc Computer science are also good options provided you pass out from an A level institute will good placements. M.Com is a better option if you are interested in academics /teaching and research career. Teaching positions in various top universities in India can fetch an attractive salary but on a general note M.Com  may not get you a good job or high starting salary easily as your main competition would be MBA graduates who are plenty in number. Coming to M.Sc Computer Science, again the college or university from which you pass out matters but even to get a good placement , your skills and knowledge will play major role as it is a technical field.  For instance if you have excellent coding skills , you may easily find a rewarding job , it is all about meeting market demands as software field is highly competitive. But M.Sc is more theoretical than application so again teaching would be good choice.  So salary in M.Com  and MSc Comp Sc. depends on the kind of job you land up in , the position level ,competition level and the company you are associated with, its based on your caliber and skills.

Hope it helps
