Why is a subsidized student loan more advantageous than a non subsidized loan?

A subsidized student loan is more advantageous than a non-subsidized loan because the government covers the interest that accrues while the borrower is in school, during the grace period, and during deferment. This means that the total amount owed at repayment is lower for subsidized loans, making them more cost-effective over time. In contrast, non-subsidized loans accrue interest immediately, increasing the overall debt burden. Thus, subsidized loans can lead to significant savings for students.
