The research aims in general to study the estimation of production costs functions as it reflects the relationship between total costs and actual production, from which it is possible to derive the most important economic indicators that reflect the extent to which agricultural production units achieve economic efficiency in their use of productive resources participating in the production process, as well as the extent to which these units achieve From maximizing profits for the agricultural product, it is also considered a study of production costs and associated important indicators, whether at the level of the production unit or at the total level, where it can be used in drawing, analyzing and determining price policies and assisting agricultural producers in making their own production decisions, which by That would encourage producers to continue or expand the production process or stop production. In addition to determining the volume of production that maximizes profits and then achieve economic efficiency from the use of productive elements Indicators of the economic efficiency of grape production with the sample of the field study show that the average total return of the grape crop amounted to about 108.7 thousand pounds, while the net per capita yield is about 21,100 thousand pounds, the average marginal surplus is estimated at about 25,068 thousand pounds, while the average total return to total costs is estimated At about EGP 1.83, the average ratio of the total return to the total production costs is about 182.79%. The average return on the spent pound is estimated at about EGP 0.83, where the average profitability of the spent pound is about 82.79%, while the average profit margin ratio for the product is about 45.29%, which Indicates a decrease in the profitability of the project
