Engineering Economy is a critical branch of engineering that bridges the gap between technical feasibility and financial viability. This paper provides an in-depth analysis of the textbook Engineering Economy (3rd Edition) by Matias Arreola. The review examines the book’s pedagogical structure, its adaptation of classical economic principles to the context of the Philippine business environment, and its utility as a foundational resource for engineering students. By analyzing key concepts such as Time Value of Money, Replacement Analysis, and Depreciation, this paper argues that Arreola’s work serves as an essential localized instrument for preparing Filipino engineers to make sound financial decisions in a globalized economy.
