The risk of individual investment in higher education is not a well-researched topic compared to the rate of return to education. In many countries tuition fees are low, but there is a possibility to borrow for investment in education. This can lead to irresponsible investment behaviour. The paper will show that the student loan market is too small to cause a macroeconomic crisis, but that it is a market with many stakeholders and irresponsible behaviour should not be encouraged. With the examination of a Hungarian sample, it can be concluded that in the context of higher education, signs of rational investment behaviour can be found. The risks of post-secondary studies are not yet fully understood and measured, and for this reason further research is suggested.
