Several studies emphasize the importance of personal financial practices in shaping the peoples’ financial planning, investment behavior, and spending decisions. However, relatively few studies have explicitly examined the relationship between personal financial practices and subjective well-being, particularly happiness. This paper aimed to determine the effect of personal financial practices on behavioral outcomes such as happiness. It employed a cross-sectional research design using correlation and regression analyses based on data gathered from 930 respondents in the Philippines. The findings indicate that personal financial practices are a significant determinant of subjective well-being, specifically happiness. Personal financial practices function as socio-economic assets that foster resilience, empowerment, and happiness. Thus, the study suggests that strengthening personal financial practices not only enhances financial stability but also contributes to broader life satisfaction and overall happiness.
