This article aims to provide an overview of the literature in which cost assessment methods are currently used, and their characteristics and limitations are also pointed out. To achieve the proposed objectives, a Systematic Literature Review (RSL) was conducted. It was possible to identify the tools discussed in the bibliographic portfolio studied, namely: life cycle costing, target costing, the total cost of ownership, activity-based costing, variable costing, and mathematical models, as well as the difficulties in implementing these tools in different application contexts. It has also been noted that multiple tools are often employed in integrated methodologies to mitigate the inherent limitations of individual models when treated in isolation. The significance of this article resides in its contribution to the discourse on the evolution of cost management tools and their application within integrated approaches, particularly in addressing the typical challenges encountered in emerging business models.
