Family farming is deficient in terms of indicators on the economic viability of its plantations, so most small Brazilian producers are unaware of the economic return on their business. This work aimed to analyze the economic viability of a yellow passion fruit plantation belonging to a small producer located in Boca da Mata, Alagoas, Brazil. In order to perform the analysis, the costs and revenues that were applied in the net present value (NPV), internal rate of return (IRR), benefit/cost ratio (B/C) and simple payback (PBS) methods were quantified. Satisfactory results were obtained with this application, since all were positive in the four tools described previously, which, consequently, resulted in the certification of the economic viability of the enterprise.
