This paper examines how behavioral intention, combined with risk tolerance, financial confidence, and self-control, relates to consumer credit usage. Inspired by the Theory of Planned Behavior, which suggests that behavioral intention is the direct precursor to actual behavior, our study investigates how these financial personality traits moderate the relationship between intention and the uptake of consumer credit. Using a combination of survey and bank register data, we focus on the amount of outstanding balance on consumer credit as the objective measure of consumer credit behavior. The results show that higher risk tolerance and greater financial confidence both are associated with increased credit use among those with the intention to borrow, while self-control mitigates this relationship. We observe that gender differences in financial behavior are notable: men who report high confidence and an intention to use consumer credit tend to carry higher outstanding balance, whereas higher self-control in men is linked to lower credit use. Additionally, although string behavioral intention and higher income both predict greater consumer credit use, self-control mitigates this association among high-income individuals. Our study adds to consumer credit research by revealing the complex interplay between behavioral intention, risk tolerance, financial confidence, and self-control in relation to actual consumer credit usage.
