What salary you will have after completing MBA will be established by you and which brand of college you have for your MBA.

You have done BMS with specialization in finance. If you like this subject, then you can opt for MBA finance to become a specialist instead of dual specialization. If you are still not sure about your interests, then dual specialization will be good.
