This empirical investigation conducts a comparative assessment of value added productivity among selected Indian oil refining enterprises, encompassing three major Public Sector Undertakings—Indian Oil Corporation Limited (IOCL), Bharat Petroleum Corporation Limited (BPCL), and Hindustan Petroleum Corporation Limited (HPCL)—and two leading private sector refiners, Reliance Industries Limited (RIL). The study's main goal is to assess how well these businesses convert input resources into economic value, hence boosting industrial productivity and the development of national value.  The study uses the additive method to calculate Value Added (VA) using publicly available financial accounts, combining net profit, employee compensation, depreciation, interest, and tax components to determine the overall wealth produced by each firm.  Value Added to Sales, Value Added to Capital Employed, Value Added to Labor Cost, and Value Added to Net Worth are the four main value-added ratios that are used as measures of stakeholder performance and operational efficiency. The analysis is predicated on secondary data that was methodically gathered from industry databases and corporate annual reports. Beyond ratio computation, the study elaborates on methodological design, descriptive statistics, and trend analysis, culminating in insights and policy implications relevant to enhancing value-added efficiency within India’s oil refining sector databases.
