Silk production has been always given special recognition by developing nations being considered as one of the most valuable agro-industrial activities since it creates high value added and enormous job opportunities either within the farm sector or at the industrial processing level. In Egypt, silk production  should have special attention not only because of the above mentioned reasons but also because local production does not meet the domestic consumption requirements although  dominant climate conditions are proper.  Pre-feasibility studies should carry out before implement the natural silk projects, this due to the High-cost investment of these types of projects. Because of the limited research conducted in this area, the study aims to: highlight the technical aspects of raising silkworms and cocoons production in terms of calculation and assessment of indicators of financial viability of setting up such projects and sensitivity analysis of changes that may occur or threaten the viability of the projects. The results of the financial assessment of the (Sericulture) project for the production of natural silk cocoons according to the criteria used in the feasibility study showed along with the results of the sensitivity analysis. The financial analysis shows high positive net present value of the net profit over the twenty years project life, with revenues significantly exceeding the capital and operating costs, and a high IRR. Values of the previous indicators evidently present high profitability perspective. Though, the project is small sensitive to change in costs and revenues. (Sericulture) project has relatively a small period of payback.
