    In order to study the elements that a company takes into account to assess the return on its investments without having defined the cost structure of capital, this study will analyze between the ways actual measurement is done and how it should be, by giving to the company Operadora del Otún S.A.S. a model with financial bases that allows it to calculate the cost structure of its capital incorporating changes in the environment and the internal structure of the company -- To achieve this objective, mixed research methodology will be applied, conducting interviews and surveys in the company Operadora del Otún S.A.S. and comparing the qualitative findings with the technical financial calculation -- It is expected that the proposed model will be applicable in the company and have use for decision making, to the extent that the information collected and provided by the shareholders and other participants is real and true -- Likewise, it is important to clarify that the result of the model will not be of general application in all entities, since specific characteristics of the current situation of the company under study are taken into account, and although in general terms they may be similar to others -- The impact of the financial strategy and its corporate management may alter the final result of the model
