Disaggregation of Corporate Return on Equity: A Methodological Contribution to the Extended DuPont Analysis

Abstract

This article aims to present a methodological contribution to the analysis of business profitability through the decomposition of Return on Equity (ROE) using the DuPont model in its two-, three-, four-, and five-factor versions. Since ROE is a key indicator for assessing the financial efficiency of organizations, the Extended DuPont model stands out as a fundamental analytical tool for understanding its operational, financial, and fiscal drivers. This framework facilitates the identification of areas for improvement and supports strategic decision-making by various stakeholders. In this context, the article offers a comprehensive conceptual framework and a detailed interpretation of the advantages and limitations of this methodology, with contributions applicable to business practice, teaching, and future empirical research.
