Dear friend,
First, When you pay salary/wages to an employee simply without any components, it is called consolidated wages and the entire sum would be taken into account for the purpose of calculation of indirect benefits like statutory bonus, contributions to EPF and ESI, gratuity if such benefits are applicable, lay-off or retrenchment compensation etc.
Secondly, under the Minimum Wages Act,1948, it has been the practice of appropriate Governments to fix the basic wages with reference to the skill-level required for the job and to add the component of variable dearness allowance linked to some cost of living index. To my knowledge no other components by way of allowances are prescribed or added under the Act except the value of other amenities required by the very nature of the job like free food etc.
If I remember correct, some States like Maharashtra and Gujarat have separate laws prescribing compulsory payment of house rent allowance which should also be treated as the part of the statutory minimum wages.
