Student Loan Debt by Major: Why Salary Matters More Than Debt

Two college graduates with different debt-to-salary outcomes illustrated side by side

Pick two students. Both graduate with $25,000 in student loans. One majored in computer engineering. The other in dance. Same debt, same diploma, totally different financial futures. The number on the loan document is almost beside the point.

The Variable Most People Ignore

Everyone wants to know how much debt they'll carry. Understandable. But FinancialAha!'s analysis of College Scorecard data flips that instinct on its head. They calculated a "debt burden ratio," dividing total debt by first-year earnings, for hundreds of majors. What they found should change how you think about borrowing.

The spread in debt across majors is surprisingly narrow. Most bachelor's programs land between $20,000 and $30,000. That's roughly a 1.5x difference from lowest to highest. But starting salaries span a 4x range. That's where the real action is.

The variable that determines your financial outcome isn't how much you borrow. It's what you earn after you borrow it.

How the Debt Burden Ratio Works in Practice

Think of the ratio as a simple clock. A ratio of 1.0 means your debt equals one full year of salary. A ratio of 0.25 means three months of gross pay clears the slate (in theory). The lower the number, the faster you surface.

Here's how major categories stack up, using FinancialAha!'s data:

Major	Estimated Debt	First-Year Earnings	Debt Burden Ratio
Systems Engineering	$21,000	$80,000	0.26
Computer Engineering	$25,000	$75,000	0.33
Computer Science	$24,000	$72,000	0.33
Nursing	$28,000	$63,000	0.44
Economics	$25,000	$58,000	0.43
Median (all majors)	—	—	0.57
Dance	$25,000	$21,000	1.15

Notice that dance and computer engineering have nearly identical debt. The ratio swings from 0.33 to 1.15 entirely because of what happens on the earnings side. Every major above a 1.0 ratio in this dataset is in arts or performing arts.

The Monthly Reality Check

Ratios are clean. Monthly payments are what actually hurt. A Credible analysis of more than 11,000 loan applications, processed through Money Management International, put hard numbers on what borrowers actually experience. They measured debt payments as a percentage of monthly gross income.

Veterinary Science: 14.62% — worst of any field studied
Psychology (undergraduate): 13.23%
Law (graduate): 12.67%
Education (undergraduate): 12.06%
History: 11.82%
Engineering: 6.88%
Economics: 6.70% — best in the dataset

The Georgia Student Finance Commission publishes a widely-used rule of thumb: keep loan payments to 8–12% of monthly gross income, and never borrow more than one year's expected starting salary. By that standard, veterinary science borrowers are already over the red line before they make a single payment.

"Don't borrow more than one year's expected starting salary." That single sentence from the Georgia Student Finance Commission does more work than any spreadsheet.

The Graduate Degree Trap

Graduate degrees are where the math gets genuinely punishing. The debts are larger, the repayment windows longer, and the earnings spike varies wildly by field.

Medicine looks brutal upfront. Median debt runs around $200,000, and residents earn roughly $60,000 during a three-to-seven-year training period. But attending physicians earn well into the $200,000–$350,000 range. The debt burden ratio collapses once training ends.

Law depends almost entirely on employer. A JD carries roughly $140,000 in debt. Firms on the BigLaw scale start associates at $225,000 (as of 2025). Public interest jobs start around $65,000. Same degree. Completely different financial outcome.

Social work is the sharpest cautionary case at the graduate level. An MSW runs about $52,000 in debt. Starting salaries average around $45,000. That's a debt burden ratio above 1.0 before adding interest, in a field where salaries grow slowly.

The Brookings Institution found that master's degree holders consume 57% of their earnings premium on loan payments, compared to 19% for bachelor's degree holders and 9% for associate's degree holders. Graduate school amplifies both the upside and the risk — which field you enter determines which one you get.

What the Lowest Debt Numbers Actually Tell You

Education Data Initiative tracks average debt by specific program. The lowest bachelor's-level debt belongs to Science Technologies: $9,915. At 5.5% interest over ten years, that works out to $107.81 per month, which is less than most people spend on a streaming subscription and a couple of takeout orders. Curriculum and Instruction bachelor's programs average $46,820, the highest of any bachelor's field tracked.

The common mistake is treating low debt as automatically good. A Science Technologies graduate earning $38,000 with $9,915 in debt sits in a tighter position than a nursing graduate earning $63,000 with $28,000 in debt. The debt number is smaller, but the ratio is worse.

This is where most college planning conversations go sideways. Families shop for schools with lower sticker prices or smaller loan packages, without anchoring those numbers to what the degree actually pays. A $15,000 loan for a major with a $25,000 median starting salary is a worse deal than a $35,000 loan for a major paying $85,000.

Who's Actually Falling Behind

The Federal Reserve's 2024 household survey put real numbers on repayment distress. Twenty percent of borrowers are behind on payments, up from 16% the year before. For borrowers earning under $50,000, that figure jumps to 27%. For those who attended for-profit schools, it reaches 35%.

These aren't abstract statistics. They describe people carrying manageable-looking debt loads (most bachelor's borrowers owe less than $30,000) but earning starting salaries that make even modest payments hard. The debt amount wasn't the problem. The salary was.

Brookings Institution research confirms the broader picture still favors college. Degree holders earn roughly $8,000 more per year than non-completers even after accounting for loan payments. But that average hides enormous variation by field. The floor is very real for certain majors.

Choosing Smarter Before You Sign

Here's a practical framework before you commit to a loan:

Find the median first-year salary for your specific major, not for "college graduates" in general. The College Scorecard (collegescorecard.ed.gov) has program-level earnings data broken out by school.
Calculate your projected debt burden ratio. Divide expected total debt by expected first-year salary. If that number is above 1.0, you need a serious plan — income-driven repayment, a higher-earning specialization, or a lower-cost school.
Run the monthly payment test. Estimate your payment using any loan calculator, then divide by expected monthly gross. If it exceeds 10–12%, treat that as a warning sign.
Graduate school requires a separate calculation entirely. The earnings premium from a master's or professional degree has to be large enough to absorb both the additional debt and the delayed years of full-time income.
Check PSLF eligibility if you're heading into social work, public health, or government roles. Public Service Loan Forgiveness changes the math on otherwise painful debt-to-income ratios for anyone committed to the 10-year repayment track.

The instinct to minimize borrowing isn't wrong. It's just incomplete. Lower debt is better, all else being equal. But the "all else" in this case is a first-year salary that could vary by $40,000 or more depending on your major.

Bottom Line

Salary drives outcomes, not debt size. Data across multiple sources shows debt varies by about 1.5x across majors; earnings vary by 4x. You're optimizing the wrong variable if you're only watching the loan amount.
Target a debt burden ratio under 0.5. That puts you in the same zone as engineering and CS graduates who report manageable repayment stress. Above 1.0 is a serious warning that deserves a concrete plan before you enroll.
The monthly payment test is non-negotiable. Divide your estimated loan payment by expected monthly gross income. Stay under 10–12%. That's where repayment stays manageable without crowding out savings, rent, and everything else.
Graduate school is a separate bet. Law, medicine, and pharmacy carry debt levels that require either high employer salaries or forgiveness programs. Social work and education master's degrees often produce ratios that make the degree a financial loss without forgiveness.
Look up your specific program on College Scorecard before signing anything. National averages for "college grads" are nearly useless for planning. Program-level data is free and takes 20 minutes to find.

Frequently Asked Questions

Which college major has the highest student loan debt?

At the bachelor's level, Curriculum and Instruction programs average $46,820 in median debt, according to Education Data Initiative. The highest debt of any degree program belongs to Pharmacy PhDs at $322,885. But high debt alone doesn't predict hardship — what matters is how that balance compares to what the degree pays.

What is a good debt-to-salary ratio for student loans?

The Georgia Student Finance Commission recommends keeping total debt below one year's expected starting salary, which translates to a ratio below 1.0. A ratio of 0.5 or lower (meaning debt is less than six months of gross pay) puts borrowers in a comfortable repayment position on a standard 10-year plan.

Is college still worth it financially even with student loans?

Brookings Institution research puts the net benefit at roughly $8,000 per year in extra earnings even after loan payments. On average, college still pays. But the average hides a wide range — degrees with weak earnings and high debt loads can produce genuinely negative returns, particularly in arts fields and some graduate programs in low-paying sectors.

Why are veterinary school graduates struggling so much with debt payments?

The Credible analysis found vet school borrowers spending 14.62% of monthly gross income on debt payments, the worst of any field studied. Veterinary medicine requires a doctoral degree (typically $150,000 or more in debt), but starting salaries for general practice vets run $80,000 to $100,000. It's a professional degree with professional-level debt and a mid-range salary — a combination the numbers don't forgive easily.

Should I pick a major based on salary alone?

No, but salary should be a concrete input, not an afterthought. The question isn't whether you should care about your work. It's whether you've honestly modeled what repayment will look like on a realistic starting salary. Plenty of people work in lower-paying fields they find meaningful and repay loans without drama — because they borrowed amounts that matched their pay. That requires planning, not luck.

What happens if my debt-to-income ratio is already bad?

Income-driven repayment (IDR) plans cap federal loan payments at a percentage of discretionary income, which can make even difficult ratios survivable month-to-month. If you work for a qualifying nonprofit or government employer, Public Service Loan Forgiveness wipes out the remaining balance after 10 years of payments. Neither option is painless, but both exist — and knowing about them before graduation changes what choices make sense.
