How to Calculate if YOUR Degree Is Worth It: A Step-by-Step Guide

Everyone has an opinion about whether college is worth it. Your parents, your guidance counselor, that guy on TikTok. But opinions don't pay your student loans. Math does.

Here's a step-by-step guide to calculating whether a specific degree at a specific school is worth the investment — using data that's free and publicly available.

Step 1: Find Your Total Cost of Attendance

The "sticker price" isn't what you'll pay. You need the net cost — what's left after grants and scholarships (not loans, which you have to repay).

Where to find it:

• College Scorecard (collegescorecard.ed.gov) — Shows the average net price by income level for every school.
• Each school's Net Price Calculator — Required by law, this tool gives you a personalized estimate based on your family's financial situation.

Write down: Annual Net Cost x Expected Years to Graduate = Total Cost

Important: use the realistic timeline. If the school's average time to graduate is 5 years, budget for 5 years, not 4.

Step 2: Add Opportunity Cost

For every year you're in school, you're not earning money. Estimate what you could earn working full-time with your current qualifications and multiply by the years in school.

Opportunity Cost = Annual Potential Earnings x Years in School

For most 18-year-olds, this is roughly $30,000-$40,000/year, or $120,000-$160,000 over four years.

Step 3: Calculate Your Total Investment

Total Investment = Total Cost of Attendance + Opportunity Cost

This is the real number. For a public university, it's typically $150,000-$250,000. For a private university, $250,000-$400,000+.

Step 4: Find the Expected Salary

Now for the return side of the equation. Look up what graduates of your specific program actually earn.

Sources:

• Ask Kinsley — Shows median salaries for specific programs at specific schools using Department of Education data.
• College Scorecard — Median earnings by field of study and institution.
• Bureau of Labor Statistics (bls.gov) — Occupational salary data by field and geography.

Write down: Median Starting Salary and Median Mid-Career Salary (10 years out)

Step 5: Calculate the Earnings Premium

Your degree's value isn't the total salary — it's the extra salary compared to what you'd earn without the degree.

Annual Earnings Premium = Salary With Degree - Salary Without Degree

The median salary for a high school diploma holder is approximately $38,000. If your degree leads to a $65,000 salary, your annual premium is $27,000.

Step 6: Calculate the Payback Period

This is the moment of truth.

Payback Period = Total Investment / Annual Earnings Premium

Example: Total Investment of $180,000 / Annual Premium of $27,000 = 6.7 years

A payback period under 10 years is generally considered strong. Under 5 years is excellent. Over 15 years? You should seriously reconsider the program or find a cheaper path to it.

Step 7: Factor in the Interest

If you're borrowing to pay for school, interest changes the math. At 6.5% interest on $35,000 in loans:

• 10-year repayment: You'll pay approximately $47,500 total (or $12,500 in interest alone)
• 20-year repayment: You'll pay approximately $62,000 total (nearly double the original loan)

Add the expected interest to your total investment before calculating the payback period.

Step 8: Apply the Gut Check

The math might say a degree pays off in 8 years. But also ask yourself:

• Can I handle the monthly loan payments on the expected starting salary?
• What's the unemployment rate for graduates of this program?
• What if I earn at the 25th percentile instead of the median? Does it still work?
• Are there cheaper paths to the same career (community college transfer, in-state options)?

A Real Example

Let's calculate for a hypothetical Nursing (BSN) degree at a state university:

• Total cost of attendance (4 years): $80,000
• Opportunity cost: $140,000
• Total investment: $220,000
• Starting salary: $77,000
• Salary without degree: $38,000
• Annual premium: $39,000
• Payback period: 5.6 years

That's a strong investment. Now run the same numbers for YOUR intended program. The results might confirm your plans — or save you from a costly mistake.
