Tabela price e anatocismo: um resgate histórico das tentati algoritmos alternativos de amortização

Abstract

The main debt amortization system used in Brazil is the Price Table, but its use over the years has provoked a great discussion regarding its application, due to the fact that there is no consensus regarding the capitalization of interest in its calculation system. The capitalization of interest, thus understood as the incidence of interest on interest, or anatocism, has been the point of controversy between mathematicians, judicial experts and operators of law. While some mathematicians claim that in the Price Table there is no occurrence of anatocism, others claim that there is this practice in the Price Table. In this context, this work aimed to analyze the existence of anatocism in the Price Table, in light of the concepts of financial mathematics and the relevant literature, as well as to rescue the attempts to create alternative models to this debt amortization system. For this purpose, an exploratory, bibliographical research of a quantitative nature was developed, in whose analysis it was sought to evidence in the specialized literature evidence of the practice of anatocism in the French system of debt amortization (Table Price). In the research, some developed algorithms were analyzed. In the context analyzed in this research, it was possible to verify the conformation of the legal framework to authorize compound capitalization in some specific situations of loans and financing, as well as the evidence demonstrated by the authors of the proposed algorithms, suggesting the existence of anatocism in the systematic calculations of the Price Table.
