This study investigates the effect of economics learning outcomes, parents' income, and students' origin on financial literacy among Indonesian high school students. Using random sampling, this research involved 206 students as respondents. The data was collected by providing tests to the students and documentation techniques. The data were analyzed by multiple linear regression with a dummy variable of students' origin. The analysis indicates that economics learning outcomes and parents' income have a positive effect on financial literacy. However, the students' origin does not have any impact on their financial literacy among Indonesian. The implications of these findings show an essential role of good economics learning in school. The better Economics learning students acquire in school will promote students' greater knowledge that can be proxied in financial literacy. Therefore, it can encourage a better formation of financial behaviors.
