Generation Z including university students who are also employed faces increasingly complex financial pressures driven by digital-centric consumerist lifestyles, social media influence, and easy access to online lending services. This situation is exacerbated by the "Fear of Missing Out" (FOMO) phenomenon and the "You Only Live Once" (YOLO) mindset, which often drive young people toward impulsive spending and a reliance on instant credit. In response, lecturers from the Accounting Study Programs at Universitas Pertiwi, Universitas Bung Karno, and Universitas Indonesia Maju organized a community service initiative: a financial literacy seminar titled "Financial Freedom: Financial Literacy for Generation Z," presented by a lecturer who is also a tax consultant and accounting practitioner. The event aimed to introduce the concept of "frugal living" as an alternative lifestyle prioritizing mindful spending, budgetary discipline, and long-term financial planning, while simultaneously curbing reliance on online loans. This article documents the seminar's implementation for working students at Universitas Pertiwi, who face unique financial circumstances due to their dual roles as students and income earners. The results indicate that frugal living, when properly understood, is not an act of stinginess but rather a reflection of a conscious and disciplined approach to managing limited resources. Participants demonstrated increased awareness regarding budgeting practices, cash flow management, and the risks associated with online loans, suggesting that structured financial education can serve as a preventive measure against problematic debt behavior among economically active young people.
