How to Use Student Loans Wisely: Borrowing, Repaying, and Avoiding Regret

How Much Student Debt Is Too Much?

The most commonly cited rule: total student loan debt at graduation should not exceed your expected first-year salary. If you'll earn $50,000 starting out, borrow no more than $50,000 total. For high-income fields (medicine, law, engineering), the math can support higher debt. For low-starting-salary careers (social work, many arts fields), even $30,000 can create a difficult repayment situation.

Federal Loans First

Always exhaust federal loan options before private loans. Federal loans offer income-driven repayment plans, forgiveness options, deferment, and forbearance that private loans lack. Federal Direct Subsidized Loans (government pays interest while enrolled) are the best deal. Unsubsidized Loans accumulate interest during school. PLUS Loans (for parents or graduate students) have higher rates and less favorable terms.

Federal Loan Types and Limits (2026)

Dependent undergrad: $5,500–7,500/year depending on year, max $31,000 total
Independent undergrad: $9,500–12,500/year, max $57,500 total
Graduate/professional: Up to $20,500/year unsubsidized, max $138,500 total

The Real Cost of Student Loans

$30,000 at 6.5% interest on a 10-year standard repayment plan = $340/month = $40,800 total paid = $10,800 in interest. If you make income-driven repayment minimums for 20 years, the total paid is significantly higher due to interest accumulation. Understanding the total cost — not just monthly payments — should inform how much you borrow.

Frequently Asked Questions

Should I pay off student loans or invest?

If your student loan interest rate is below 6%, investing often wins long-term (expected stock market returns of 7–10% historically exceed debt cost). Above 7–8%, paying loans aggressively makes more mathematical sense. For federal loans, the peace of mind from being debt-free has real value even if the math slightly favors investing.

What is Public Service Loan Forgiveness (PSLF)?

PSLF forgives remaining federal loan balance after 10 years (120 payments) of qualifying public service employment and income-driven repayment. Qualifying employers: government agencies, 501(c)(3) nonprofits, some other public service organizations. This can be extremely valuable for borrowers with high debt loads entering public service careers.
