Investment analyses performed in a satisfactory way are essential for companies to apply capital resources in appropriate projects. To this end, the correct quantification of cash flow components, as well as the quantification of the depreciation, inflation and tributary impact of the income tax in economical-financial analysis is fundamental. Hence, the purpose of this study was to evaluate different forms of including inflation in investment analyses and discuss the depreciation role and its impacts. The article indicates two methods of analysis: homogeneous, where every component in the cash flow is updated by the same inflation index; and, heterogeneous, where each component is updated by a different inflation index. Results showed the impact of these two different concepts on the analysis, indicating the necessity of managers to focus on the issue of inflation during the assessment of their projects.
