Since males and females are raised differently by their parents (Thorne, 2003), gender roles may affect the saving and spending behaviours of male and female teenagers. The objective of this research was to study the gender differences in saving and spending behaviours of Thai students. This was an exploratory study where a questionnaire was used to collect information from four hundred and fifty-five students. The data were analysed using a Fisher exact test and a t-test for two independent samples. The results showed that female and male students did not have different saving behaviour, although females had a more positive attitude towards saving and shopping than males. In addition, females were more concerned about being rich or having a lot of money than males, while males had a more positive attitude towards spending money than females. The study also revealed that female and male students bought different types of products.
