Digital saving has become increasingly important for income-earning university students in urban areas because their financial choices are shaped by both their understanding of digital financial services and their ability to control spending impulses. Methods: This study analyzed the effects of financial technology literacy and self-control on digital saving decisions among income-earning students in South Jakarta. A descriptive quantitative design and purposive sampling were applied. Primary data were collected through an online questionnaire using a four-point Likert scale. After screening against the inclusion criteria, 102 valid responses were retained. Instrument quality was assessed through item validity, reliability, and exploratory factor analysis, while the hypotheses were examined using multiple linear regression with diagnostic testing. Results: Financial technology literacy had a positive and significant effect on digital saving decisions, with a standardized beta coefficient of 0.467. Self-control also had a positive and significant effect, with a standardized beta coefficient of 0.376. Jointly, both variables explained 59.7 percent of the variance in digital saving decisions, with financial technology literacy showing the stronger standardized effect. Conclusion: Digital saving decisions among income-earning students are strengthened when adequate understanding of digital financial services is accompanied by disciplined control of spending behavior and financial goals. These findings indicate that effective interventions should integrate financial education with behavioral reinforcement to encourage healthier digital financial behavior among young adults.
