Abstract. Financial literacy encompasses the awareness, knowledge, skills, attitude, and behavior necessary for making informed financial decisions and achieving financial well-being. This study utilized the ADDIE model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. Data were gathered from learners, licensed financial advisors, and experts using validated and reliable instruments such as questionnaires, evaluation checklists, journals, and written interviews. Analysis methods included mean, standard deviation, rank, and thematic analysis. The findings revealed that learners exhibited a moderate level of financial literacy. Licensed financial advisors identified five specific Business Mathematics lessons where financial literacy could be effectively integrated. The resulting instructional module was evaluated based on its learning objectives, content, organization, presentation, format, design, activities, assessments, and integration of financial literacy. Experts rated the module as "Highly Acceptable," while learners found it "Acceptable." The module was praised for its uniqueness, interest, clarity, effectiveness, flexibility, and ability to enhance the understanding and application of mathematical concepts while promoting financial literacy. Consequently, it is deemed suitable for integrating financial literacy into Business Mathematics lessons. Further research is recommended to evaluate the module's impact on academic achievement and to develop similar instructional materials for other relevant subjects.
