Dear Marvyn,
In my company I deal with manpower cost for various projects all over India. I have drafted a standard format to calculate the monthly manpower cost. Though this format is related to fixed nature labour with statutory cost.
Hope the format will help to meet your requirement. You can re-draft the structure as per your requirement. If any more clarification required, do let me know.
Seniors can throw more light on the matter.
