This study uses a quantitative approach with descriptive and verifiable methods. Data was collected through questionnaires distributed to 100 active student respondents from Sangga Buana University in Bandung.

The results showed that simultaneously, financial literacy, locus of control, and lifestyle have a significant effect on students' financial behavior. Partially, financial literacy has a positive and significant effect on financial behavior, which indicates that the higher the students' understanding of finance, the better their financial behavior. Locus of control also has a significant positive effect, indicating that students with confidence in internal control over their lives tend to have better financial behavior. On the other hand, lifestyle has a negative effect on financial behavior, which means that the more consumptive the lifestyle of students, the worse their financial behavior.
