In this study, data collection was carried out by means of a survey through the distribution of questionnaire surveys (questionnaires) distributed to respondents to be filled in. The data analysis technique in this study uses the Warp PLS (Partial Least Square) structural equation model. Hypothesis testing is used to explain the direction of the relationship between independent variables and dependent variables. SmartPLS 3.0 program. Results: Based on the results of the Effect Size (F-Square) test, the results of the study obtained on Financial Literacy (X1) on Consumption Behavior (Y) obtained a value of 0.171, so that these results can identify that it has a Medium influence, because the value is greater than 0.15. Financial Experience (X2) on Consumption Behavior (Y) obtained a value of 0.191, so with these results it can be identified as having a Medium influence, because its value is greater than 0.15. Financial Experience (X2) mediated by Financial Technology (Z) obtained a value of 0.208, so with these results it can be identified as having a Medium influence, because its value is greater than 0.15. Financial Self Efficacy (X3) on Consumption Behavior (Y) obtained a value of 0.373, so with these results it can be identified as having a Large influence, because its value is greater than 0.35. Financial Self Efficacy (X3) mediated by Financial Technology (Z) obtained a value of 0.496, so with these results it can be identified as having a Large influence, because its value is greater than 0.35. Financial Technology (Z) which mediates Consumption Behavior (Y) obtained a value of 0.244, so with these results it can be identified as having a Medium influence, because its value is greater than 0.15.
