This study was conducted in order to assess the financial viability of goats rearing in district Kohistan, Khyber Pakhtunkhwa during the year 2012-13. The average per flock per annum cost incurred for large flock size was Rs. 603883.16 and for small size was Rs. 664920.69. Resultantly, annual net return was estimated Rs. 78477.13 for small group and Rs. 277440.0 for large group. The NPV was observed to be positive (considering interest rate of 14.5 percent as per ZTBL charges for livestock enterprises) for both large and small flock size as Rs.165704.83 and Rs. 34990.09, respectively. B/C-ratio was found greater than one (1.29 in case of small and 1.45 in case of large groups). Finally, the IRR value 29.65 percent in case of small group and 46 percent in case of large group was greater than the required rate of return which supports the financial viability of the enterprise.
