Student loan debt has been rapidly increasing, reaching $1.2 trillion in 2015. This study looked at how this growing debt could affect people's ability to retire comfortably. By analyzing data on household finances, the researchers found that having student debt can increase the risk of not having enough money for retirement. If all working households had the same level of debt as recent college students, the percentage of households at risk of not having enough money for retirement would increase by 4.6 points. In conclusion, the rise in student debt is making it harder for many households to save enough for retirement.
