You are interested to determine net take home ( NTH) salary 11K per month. My suggestions are as follows :-
1. Based on your industry, skill category of the employee and after determination of Zone - A OR B - find out the minimum wages.
2. In WB there is 5% HRA on Basic & DA is to be paid as per HRA Act,
3. Then deduct PF contribution, ESI contribution & PTAX if any.
4. You will arrive the NTH.
The organization has to comply Minimum wages, PF, ESI etc. at the time of determining the NTH.
