This study was conducted to determine the precision returns of range plans of Karhpo range plan, Ilam by engineering economy methods based on the data and information collected. The results showed that the criterion of net present value (NPV) had a positive net value to a discount rate of 26.00%, while its effect was zero at a discount rate 26.56%. Besides, the benefit-cost ratio (BCR) was higher than 1 until the discount rate of 26%, while it was equal to 1 at the discount rate of 26.56%. Internal Rate of Return (IRR) of 26.56% for plan was economically practical during 9-years period. Given the proper financial explanation of the plan, it is better to adopt a method and policy for assigning and implementing the range plans to beneficiaries in order to making ranchers more willing to implement the plans. The government can also participate more actively in range plans with providing parts of the costs and improving economic efficiency (return) of plans.
