Ginning represents a major part of the cost of getting a bale of cotton into a marketable condition. Predicting actual ginning costs requires burdensome amounts of input information which may not be available. This paper presents a simplified approach to getting a rough estimate of the cost of ginning cotton with minimum input. Costs are calculated by estimating variable costs from surveys and computing fixed costs from a simplified version of GINMODEL. A detailed economic feasibility study should be conducted before an investment is made in ginning capacity.
