This article aims at finding the relationship between households' personality traits and their financial literacy level. The data in this research are from the household survey which can represent the population in Dutch. Using the Big Five personality traits and economic locus of control--extraversion, agreeableness, conscientiousness, emotional stability, intellect, internal locus of control, and external locus of control--I have found that those people whose personality traits are intellect and internal locus of control tend to have higher level of financial literacy than those with other personality traits.
