Is College Worth the Debt? How to Do the Math for Yourself

The question "is college worth it?" gets debated endlessly at the national level. That debate is not useful to you. What matters is whether a specific degree from a specific school, at a specific cost, is worth it for your particular situation.

That is a math problem. And it is one most 17- and 18-year-olds are never asked to solve before they sign a promissory note.

This post gives you the framework to run the numbers for yourself - before you commit to four years and tens of thousands of dollars.

The Core Calculation: Return on Investment

Every education decision is an investment. Like any investment, the question is whether the expected return justifies the cost.

The basic ROI framework for college:

Benefit: The income premium - how much more you expect to earn with a degree versus without one, over your working career.

Cost: Total money spent on the degree plus opportunity cost - what you would have earned working full-time instead of attending college.

When the lifetime income premium substantially exceeds the total cost, college is a strong financial investment. When it does not, the math is working against you.

Step 1: Estimate Your Degree's Income Premium

The Bureau of Labor Statistics publishes median weekly earnings by education level. As of 2025:

Source: Bureau of Labor Statistics, Education Pays 2024

But medians are averages of wildly different fields. The real number to research is median starting salary for your specific intended major and career path.

Where to find field-specific salary data:

• Bureau of Labor Statistics Occupational Outlook Handbook - median pay, job growth, education required for every major occupation
• PayScale.com - starting salaries by major and institution
• NACE (National Association of Colleges and Employers) - annual starting salary surveys by major

Sample starting salaries by major (2025 NACE data, approximate):

The income premium from a Computer Science degree is vastly different from the income premium from a Fine Arts degree. Treating "college" as a uniform investment ignores this entirely.

Step 2: Calculate Your True All-In Cost

The sticker price of college is not your cost. Your cost is:

Tuition + fees + room and board + books + personal expenses - grants and scholarships = out-of-pocket cost per year

Multiply by 4 (or 5 if you expect to take longer). This is your direct cost.

Then add opportunity cost: what you would have earned working full-time during those years instead. At $35,000-40,000/year for an entry-level job, that is $140,000-160,000 over four years. This money does not show up on any bill, but it is real money you are not earning.

Total college cost = Direct costs + Opportunity cost

Most people look only at tuition. The full number is 2-3x larger.

Step 3: Run the Break-Even Calculation

With your income premium and total cost estimated, calculate how long it takes to break even.

Formula:

Break-even years = Total all-in cost / Annual income premium

Example A - Computer Science at an in-state public university:

• Total all-in cost: $232,800
• Starting salary with degree: $82,000
• Starting salary without degree (working full-time from 18): $40,000
• Annual income premium: $42,000
• Break-even: $232,800 / $42,000 = 5.5 years

By 27 or 28, this person has broken even and every subsequent year earns $42,000+ more than they would have without a degree. Over a 40-year career, the degree adds roughly $1.68 million in additional earnings before taxes. This is a strong investment.

Example B - Sociology degree at an out-of-state private university:

• Total all-in cost: $380,000 (higher tuition, no in-state discount)
• Starting salary with degree: $40,000
• Starting salary without degree: $36,000
• Annual income premium: $4,000
• Break-even: $380,000 / $4,000 = 95 years

This person will never break even financially. The degree cost more than its lifetime income premium. That does not mean it is a wrong choice - there are non-financial reasons to pursue any education - but it means the financial case is very weak, and the debt burden will be severe relative to the salary it enables.

The Loan-to-Salary Rule

A widely used heuristic from financial planners: total student loan debt at graduation should not exceed your expected first-year salary.

If you expect to earn $55,000 starting, your student debt ceiling is $55,000. At that level, standard repayment on a 10-year plan requires roughly $550-600/month - challenging but manageable.

Borrowing $120,000 to enter a field that pays $42,000 starting means your loan payment may equal 20-25% of your take-home pay before you pay for rent, food, or anything else. That is a financial trap that can take 20+ years to exit.

When debt significantly exceeds starting salary, the percentage of take-home required for repayment becomes structurally unmanageable.

When College Is Clearly Worth It

• Your intended field has a well-established degree requirement and strong salary premium (medicine, engineering, nursing, accounting, computer science)
• You can attend an in-state public university and keep net cost below $15,000/year after grants
• Your total debt will stay below your projected first-year salary
• You have a clear major and career direction (vague plans produce vague outcomes at significant cost)

When College Warrants Real Skepticism

• You plan to major in a field with a weak salary premium and no clear licensing requirement
• You are attending a high-cost private school with minimal financial aid
• Your total debt will exceed 1.5-2x your expected starting salary
• You have no clear direction and plan to "figure it out" once enrolled (colleges are not great at this, and the cost of uncertainty is $30,000-50,000/year)
• The specific career path you want does not actually require a four-year degree (many tech, trade, and creative fields do not)

Alternatives Worth Knowing About

Community college + transfer: Two years at a community college costs $8,000-15,000 total. Transfer to a four-year school for the final two years. The diploma from the four-year school is identical. The debt is a fraction.

Trade and vocational programs: Plumbers, electricians, HVAC technicians, and dental hygienists earn $55,000-90,000 with 1-2 year programs. The loan-to-salary ratio is often better than a four-year degree.

Employer-sponsored education: Many large employers (Amazon, Starbucks, Walmart, UPS) offer tuition assistance. Working full-time and taking courses with employer funding produces zero debt.

Bootcamps and certifications: In technology and data fields, employer acceptance of intensive programs has grown substantially. A credible software development bootcamp at $12,000-18,000 can produce outcomes comparable to a $100,000+ computer science degree - with different trade-offs in depth.

Real-World Examples

Example: Jamie, 18, interested in nursing

Situation: Jamie was accepted to a private nursing school ($48,000/year) and a state school nursing program ($22,000/year including room and board). Both lead to an RN license.

The math: Private school total net cost over 4 years: $192,000. State school: $88,000. Both lead to approximately the same starting salary of $65,000-70,000.

What Jamie did: Chose the state program. Graduated with $31,000 in loans (kept below the one-year-salary threshold). Paid off in 4 years on standard repayment. The private school path would have taken 12+ years to reach the same loan-free position.

Example: Devon, 18, undecided major

Situation: Devon was admitted to several schools but genuinely had no idea what to study. He felt pressure to choose and enroll.

What Devon did: Enrolled at a community college for two years instead. Used the time to take a range of courses, work part-time, and research careers he found interesting. Transferred to a state university as a junior with a clear major (information systems) and only $9,000 in debt.

Result: Graduated at 22 with $24,000 total debt and a $68,000 starting salary. His peers who enrolled undecided at four-year schools frequently changed majors and many took 5 years to graduate - at significantly higher total cost.

Example: Alexis, 19, passionate about art

Situation: Alexis received an offer from a prestigious art school at $55,000/year. Her dream was to work in animation.

The math: $220,000 in net cost. Median salary for animators: $68,000. Entry-level: $42,000-48,000. Loan-to-salary ratio would be 4:1 to 5:1 - far above the advisory threshold.

What Alexis did: Attended a state school with a strong art program at $18,000/year. Supplemented with online courses and built a portfolio independently. Graduated with $40,000 in debt. The prestigious school name did not guarantee employment in animation - portfolio quality did.

The Honest Bottom Line

College is worth it for many people and not worth it for others. The answer depends on specific numbers: how much it will cost you after aid, how much it will actually increase your income, and how the debt-to-salary ratio looks at graduation.

Run the numbers before you commit. Most 17-year-olds make a $200,000+ financial decision based primarily on school rankings, campus tours, and social pressure. You now have a framework that most adults never use. Use it.
