In the same way that compounding interest over a long period of time can significantly increase your savings, repaying interest on a loan over a long period of time can significantly increase debt – debt that college graduates often have a difficult time repaying with an entry-level salary.
For example, if you save $23,400 (or $25 a week) with TNStars over 18 years that could add up to $42,000 for college. A child who borrows that same $42,000 could end up repaying almost $60,000.
