Estimate what your options are really worth after Indian tax — perquisite tax when you exercise, capital gains when you sell.
Assumptions: unlisted Indian company shares; resident individual; LTCG if held > 24 months after exercise, taxed at 12.5% + cess (no indexation); STCG taxed at your slab; 4% cess included; surcharge ignored. The FMV at exercise must come from a merchant banker valuation — this tool is indicative only, not advice.
