This quantitative study examines the effects of peer pressure on allowance management among Senior High School students. The study focuses on how social influences shape students’ financial decisions, including spending, budgeting, and saving behaviors. Survey data gathered from Senior High School students were analyzed using descriptive and inferential statistics. Results show that peer pressure has a statistically significant influence on students’ budgeting practices and spending behavior. Students reported adjusting their spending to participate in group activities, purchasing items to fit in, and experiencing difficulty saving due to peer influence. However, findings also reveal that many students demonstrate awareness and employ strategies to resist negative peer pressure, such as setting financial goals and prioritizing needs over wants. Overall, peer pressure exists at a moderate level and affects financial behavior, but it does not completely override students’ ability to manage their allowances responsibly. The study highlights the importance of financial literacy programs that strengthen students’ independence and decision-making skills.
