Americans owe more than $1.7 trillion in federal student loans, spread across roughly 43 million borrowers, with an average balance of about $38,000. Debt is not just a young person's problem: while borrowers aged 25–49 hold the largest share, balances per borrower are often highest in the 35–61 range, and debt among people 50 and older has grown quickly — partly from parent loans and slow repayment.
Graduate and professional degrees drive the biggest balances, since undergraduate borrowing is capped. Whatever you owe, a clear payoff plan helps: pay more than the minimum on the highest-rate loan, check eligibility for income-driven repayment or forgiveness, and consider refinancing private loans if you can lower the rate.

These statistics come from US Department of Education / Federal Student Aid data and cover federal loans; private student loans add more. Student-debt systems differ abroad — the UK, Canada and Australia use income-contingent repayment models that work very differently from US loans.
Aggregate student-debt figures conceal an extremely uneven distribution. Average balance is pulled upward by a relatively small group of graduate and professional borrowers carrying very large sums, while the typical undergraduate balance is far lower. Median and average differ enough here that they support opposite conclusions from the same data.
Balance alone is also a poor guide to hardship. What determines whether a loan is manageable is the ratio of payment to income, and federal income-driven plans are built on exactly that: payments are set as a share of discretionary income rather than as a function of the balance. A large balance on a high income can be easier to service than a modest balance on a low one.
The federal and private halves of the market behave very differently too. Federal loans carry fixed rates set by statute, plus access to income-driven repayment, deferment and forgiveness routes. Private loans are underwritten on credit, often variable-rate, and carry none of those protections. A statistic that merges the two describes a market that does not really exist.
