The principal point of this study is to examine the relationship between the spending pattern and consumer behavior, especially as it relates to income and financial literacy, among public and private university students in Malaysia. This study adopts Keynes's Psychological Law of Consumption theory.

In addition, this study seeks to determine how well students comprehend the idea of needs and desires. The association between students’ degree of financial literacy as well as their income and their spending habits will next be examined using the data. The link between endogenous and exogenous variables will be determined over both the long and short terms using the Statistical Package for the Social Sciences (SPSS) version 23. The study includes the findings from earlier investigations. The study contributed to a new understanding for the researcher of financial behavior under the categories of needs and wants which outline the importance of financial literacy, parents’ income, and demographic factors.
