Dear Nihal,
Nowadays, in the IT revolution, there are no restrictions on what heads the salary/compensation package should be based. The salary structure is based on various disciplines and competencies, fitted into a time scale, such as starting salary and maximum salary in the time scale for different groups. If you have different departments, then all the HODs, then Senior Management, Middle Management, Junior Management, etc. I am not sure if your Rs. 50000/- is only the Basic + Allowance or what we call as CTC. Nowadays, CTC is the trend to attract many candidates. As you know, CTC includes PF, LTC, Medical Allowance, gratuity, leave salary, etc., by which a very high figure is shown to the candidate, whereas the take-home or monthly salary bill shows half of it. However, here are some suggestions.
Generally followed: Basic + DA + city compensatory allowance + conveyance allowance + medical allowance + lunch allowance + production-linked incentive bonus, etc. Some establishments also add a Uniform allowance on a monthly basis. You may distribute the total emoluments among these items and decide. Why don't you refer to your company's past structure for this purpose?
