How Major Choice Affects Student Loan Repayment

Introduction

Choosing a major is both an academic and financial decision. The subject you study shapes your initial and long-term earnings, the time and cost to reach professional credentials, and the likelihood you’ll need flexible repayment options. Those factors directly affect how much you pay each month, how long you carry debt, and whether programs like income-driven repayment (IDR) or Public Service Loan Forgiveness (PSLF) are realistic options.

In my work advising clients on student debt, I regularly see two outcomes: graduates from high-demand majors who move quickly into well-paid roles and repay loans faster, and graduates from lower-paying fields who rely on extended repayment, forbearance, or IDR plans. Understanding the mechanisms below helps students and families make choices that reduce long-term financial risk.

How major choice affects repayment — the main channels

Major choice matters for loan repayment through three primary channels:

1. Earnings potential and starting salary
2. Time and cost to credentialing or further education
3. Job market stability and career path volatility

Earnings determine your ability to make standard payments and to qualify for discretionary solutions such as refinancing. Time to credentialing matters because additional years of education increase both total cost and lost earnings while studying. Market stability affects income continuity — gaps or underemployment can force borrowers into deferment, forbearance, or IDR plans.

Earnings and repayment speed

Higher starting salaries let graduates either make larger monthly payments or pay the same amount and shorten the loan term. For example, typical starting salaries for occupations like software engineering, nursing, or engineering are often materially above the general median for bachelor’s degree holders, boosting repayment capacity (U.S. Bureau of Labor Statistics; BLS). Conversely, many liberal arts, education, and arts majors start lower and may need IDR plans.

Tip: Use the BLS Occupational Outlook and your college career services to compare median wages for roles tied to each major (BLS, bls.gov).

Credentialing, extra costs, and delayed earnings

Some majors require graduate or professional degrees (e.g., medicine, law, some allied health careers) or long licensure periods. These paths increase both direct costs and opportunity costs — months or years without full professional pay. That can raise cumulative borrowing and extend repayment timelines.

Example: A nursing graduate who becomes an RN quickly may earn and repay faster than a student who pursues a doctorate requiring several more years of tuition and living expenses.

Job-market demand and underemployment risk

Majors tied to expanding industries (tech, healthcare, certain trades) usually offer lower unemployment and faster job matches. Fields with low or unpredictable demand (some arts and humanities niches) carry higher underemployment risk, which translates into more borrowers on IDR plans or relying on forbearance.

Comparing majors: risk vs reward (simple ROI approach)

A basic ROI calculation helps quantify tradeoffs.

• Total cost = tuition + fees + living expenses + loan interest during school
• Expected first-year salary = median starting wage for graduates in your field
• ROI proxy = Expected first-year salary ÷ Total cost (higher is better)

This quick calculation won’t capture career progression, but it highlights which majors are likely to produce faster repayment capacity. Use college net price calculators and BLS salary data to populate the inputs.

Repayment strategies tied to major choice

Different fields make certain repayment tools more or less sensible.

• Graduates from higher-paying majors often benefit from refinancing private or federal loans to get a lower rate and pay off debt faster. But refinancing means losing access to federal protections (IDR, PSLF), so consider this only if you have stable, high income and no public-service plans.

• Lower-paying majors may rely on federal IDR plans (including the updated SAVE plan) to set payments based on income. These plans can reduce monthly payments but extend repayment and may increase total interest cost. SAVE reduces unpaid interest for many borrowers and is currently the most generous IDR option (Federal Student Aid, studentaid.gov).

• Students entering public service, education, or nonprofit roles should evaluate PSLF. If your major naturally leads to qualifying public-service employment, PSLF can be a strong strategy — but it requires careful tracking and qualifying payments (studentaid.gov).

Practical examples (real-world framing)

• STEM graduate: A client with a computer science degree earned a competitive starting salary, used standard 10-year repayment, and paid down a $30,000 balance in ~3 years by applying extra payments. The major gave both the income and short-term job stability to do that.

• Low-paying major: Another client with a humanities degree started at a lower salary and used an IDR plan (SAVE) to keep payments affordable while pursuing graduate study part-time. His balance grew slowly due to interest, but the option to cap payments based on income prevented default.

These cases show how the same loan balance can behave very differently depending on the major-driven income trajectory.

Choosing a major when debt is a concern — five practical steps

1. Research salary ranges and job outlooks for careers tied to each major (BLS). Combine national data with local job market intelligence.
2. Calculate expected total cost (net price calculators) and perform a simple ROI check as shown above.
3. Factor in credentialing time: how many years until you earn full professional wages? Add those years’ costs to the total.
4. Look for hybrid routes: minors, certificates, internships, or bootcamps that increase employability without extra degrees.
5. Plan for contingency: if you end up underemployed, know which federal protections (IDR, deferment, forbearance, SAVE, PSLF) are available. See Federal Student Aid for current rules and program specifics (studentaid.gov).

Policy and labor-market context (2025 update)

Total outstanding U.S. student loan debt remains a macro-level concern. For individual borrowers, the most consequential policy changes in recent years are improvements to IDR (notably the SAVE plan) and temporary enhancements to PSLF processing and qualifying counts. These changes make income-based support more accessible for lower-earning graduates, but they do not replace the value of selecting a major that offers a clearer earnings trajectory (Federal Student Aid; U.S. Department of Education).

Common misconceptions

• “Any college degree guarantees high pay.” Reality: degree field matters. Earnings vary widely by major and occupation (BLS).
• “Refinancing always saves money.” Refinancing can lower rates but eliminates federal protections. It’s a tradeoff that depends on income stability and whether you plan to seek forgiveness (consumerfinance.gov).
• “You must choose the highest-paying major.” Fit matters. A sustainable career often combines earnings potential with skills, interest, and resilience.

My professional recommendations

In my practice I walk clients through both numbers and preferences. If debt is likely, prioritize majors or mixed pathways (major + marketable minor/certificate) that improve employability within 6–18 months of graduation. If you prefer a lower-paying field, build contingency funding, seek internships, and understand IDR benefits before borrowing heavily.

Final checklist before you declare a major

• Did you compare expected salaries and job openings (local and national)?
• Did you compute total cost and run a simple ROI calculation?
• Did you ask about on-campus internships, co-ops, or employer connections?
• Do you know which repayment and forgiveness options align with likely career paths?
