Saving as financial management is one of the wise habits that must be cultivated from an early age. However, it is a challenge to introduce this habit to elementary school children. Although the government has implemented the "SIMPEL" program to introduce this habit, it is still difficult to accept due to the mindset of children who are at the level of fun and play. Therefore, social support, especially teachers, and strengthening students' self-efficacy is needed to behave wisely in saving as financial management. This study aims to determine the effect of teacher social support and self-efficacy on student saving behavior, both direct and indirect influences. A total of 73 students were respondents in this study. The data that has been obtained will be processed through path analysis with SmartPLS. The results of this study that students' saving behavior is influenced by teachers' social support and self-efficacy both directly and indirectly. Where self- efficacy can mediate between teachers' social support and students' saving behavior.
