How do you calculate salary slips on a cost-to-company basis?

== == Cost to company in brief means all the cost which the company incurrs for maintaining the employee. This generally includes not just the salary which the employee draws at the end of the month but also includes all the other components like 1. Employer contribution to PF 2. Employer contribution for insurance / pension schemes 3. meal subsidies 4. travel subsidies etc. This may not neccessarily form part of the salary slip, but are taken into consideration for computing cost to company
