The Supreme Court justices deciding whether to end Biden's student loan relief program paid an average of $42,539 to go to college. Today, they'd have to pay around $320,531.

• The Supreme Court heard oral arguments for Biden's student debt relief on Tuesday.
• The court could rule to strike down the plan that would benefit millions of Americans.
• The cost of getting an undergraduate degree was significantly cheaper when they graduated than now.  

The Supreme Court in the coming months will decide whether President Joe Biden's student-loan forgiveness program can stand and potentially offer relief to millions of borrowers or keep them saddled with the debt. 

On Tuesday, the High Court heard oral arguments on the loan forgiveness plan, with the conservative justices, who hold the majority, questioning if Biden had the authority to enact widespread forgiveness.
