This study aimed to analyze the influence of social media, peer groups, and lifestyle on the consumptive behavior of Retail Business Department students at SMK Negeri 14 Jakarta, both partially and simultaneously. This study employed a quantitative method with a survey approach. The sample consisted of 140 respondents selected using the proportional random sampling technique. Data were collected through questionnaires and analyzed using IBM SPSS Statistics Version 24 with multiple linear regression analysis.
