Same Major, Wildly Different Salary: How Your College Choice Affects Your Paycheck by $40,000 -- or More
The Myth of "It's the Major That Matters"
The conventional wisdom on college ROI goes like this: pick the right major, and the school matters less. Study computer science anywhere and you'll be fine. Study business at any accredited school and you'll land a decent job.
That's not what the earnings data shows.
CollegeBound analyzed federal College Scorecard earnings data for graduates of the same major across hundreds of institutions -- tracking median salary four years after graduation for students who all earned the same degree. The salary gaps are not explained by geography or industry alone. They're systematic, consistent, and large enough to matter enormously over a career.
Computer Science: A $227,000 Gap Across 231 Schools
Computer science has the widest earnings spread of any major in our dataset. Four years after graduation, CS graduates range from $28,778 annually to $256,539 depending on where they went to school.
Top CS earners at 4 years post-graduation:
| School | Admission Rate | CS Median Earnings (4yr) |
|---|---|---|
| Harvard University | 3% | $256,539 |
| Carnegie Mellon University | 11% | $247,552 |
| Brown University | 5% | $218,525 |
| Stanford University | 4% | $200,950 |
| MIT | 5% | $199,774 |
| Cornell University | 8% | $185,679 |
| Harvey Mudd College | 13% | $183,524 |
| UC Berkeley | 12% | $178,867 |
| Rose-Hulman Institute of Technology | 73% | $157,625 |
| University of Illinois Urbana-Champaign | 44% | $143,775 |
That last two entries deserve emphasis. Rose-Hulman, a small engineering-focused school in Terre Haute, Indiana that admits 73% of applicants, produces CS graduates earning $157,625 four years out. UIUC, which admits 44%, produces CS graduates earning $143,775. Both are more accessible than the Ivies and still outpace USC ($143,152), Northwestern ($130,650), and Georgetown ($126,103).
Mid-tier accessible CS programs with strong earnings:
| School | Admission Rate | CS Median Earnings (4yr) |
|---|---|---|
| University of Washington | 43% | $144,297 |
| University of Rochester | 36% | $136,559 |
| UC San Diego | 25% | $131,731 |
| RPI | 58% | $129,412 |
| Rochester Institute of Technology | 71% | $125,429 |
| Worcester Polytechnic Institute | 58% | $124,359 |
| Purdue University | 50% | $116,601 |
| Binghamton University (SUNY) | 38% | $114,997 |
A student choosing between Purdue ($116,601 median CS earnings, $28,794 OOS tuition) and, say, a lower-ranked private school at $50,000+ tuition is not making a lateral tradeoff.
Nursing: The $90,000 Geography and School Premium
Nursing is one of the most credential-standardized professions in the country -- all nurses take the NCLEX-RN, work in the same hospitals, and hold the same licenses. The salary difference should be minimal, right?
Wrong. Across 780 schools with nursing programs, four-year post-graduation earnings range from $47,274 to $139,795. That's a $92,521 gap for people holding the same license doing the same job.
The pattern is stark and geographic: California-based nursing programs produce the highest-earning graduates by a wide margin, driven by California's significantly higher nursing wages.
Top nursing programs by 4-year graduate earnings:
| School | State | Admission Rate | Nursing Earnings (4yr) |
|---|---|---|---|
| Cal State East Bay | CA | 97% | $139,795 |
| Dominican University of CA | CA | 96% | $132,781 |
| San Francisco State | CA | 96% | $132,542 |
| University of San Francisco | CA | 51% | $127,245 |
| Sonoma State | CA | 95% | $124,083 |
| Cal State Sacramento | CA | 94% | $123,869 |
| Cal State Northridge | CA | 93% | $110,342 |
The nursing earnings finding cuts against the usual premium-private-school advice. Cal State East Bay admits 97% of applicants and charges $11,000 per year in-state tuition. Its nursing graduates earn more than graduates of nursing programs at schools that cost three times as much.
Non-California schools with strong nursing outcomes:
| School | State | Admission Rate | Nursing Earnings (4yr) |
|---|---|---|---|
| CUNY Lehman College | NY | 55% | $112,500 |
| Farmingdale State (SUNY) | NY | 69% | $111,965 |
| Mercy University | NY | 85% | $113,576 |
| Wagner College | NY | 83% | $109,601 |
Bottom of the nursing earnings table (non-PR schools):
| School | State | Admission Rate | Nursing Earnings (4yr) |
|---|---|---|---|
| Bluefield State | WV | 87% | $52,975 |
| Lincoln Memorial | TN | 59% | $54,229 |
| Freed-Hardeman | TN | 91% | $53,436 |
| Brigham Young University | UT | 69% | $47,274 |
A student planning to work in California should strongly consider attending school there. The nursing premium in California is so persistent that even highly accessible Cal State campuses outperform well-known private universities nationally.
Business Administration: The $80,000 Split
Business administration is the most commonly declared major in the country. It also has an enormous earnings spread -- $34,012 to $115,546 at 4 years out -- that makes the school choice especially consequential.
Top business programs by 4-year earnings:
| School | Admission Rate | Business Earnings (4yr) |
|---|---|---|
| New York University | 9% | $115,546 |
| Southern Methodist University | 61% | $105,314 |
| UNC Chapel Hill | 19% | $105,246 |
| Manhattan University | 78% | $104,296 |
| Santa Clara University | 44% | $101,411 |
| Stevens Institute of Technology | 43% | $100,049 |
| Boston College | 16% | $98,724 |
| Brigham Young University | 69% | $96,358 |
| Fordham University | 56% | $96,453 |
| Lehigh University | 29% | $95,363 |
SMU at 61% admit produces business graduates earning $105,314 -- ranking among the best in the country for business ROI. BYU at 69% admit produces graduates earning $96,358. Both are significantly more accessible and affordable than schools at the top of traditional business program rankings.
Mechanical Engineering: A Tighter Range, Still Meaningful
Mechanical engineering has the most compressed salary range of the majors analyzed ($54,268 to $101,532 at 4 years) -- which actually makes the mid-tier school case stronger. You don't need a top-5 school to reach the ceiling.
Top mechanical engineering earners:
| School | Admission Rate | ME Earnings (4yr) |
|---|---|---|
| Duke University | 7% | $101,532 |
| Cal Maritime Academy | 99% | $101,325 |
| SUNY Maritime College | 79% | $99,578 |
| Santa Clara University | 44% | $99,067 |
| MIT | 5% | $98,644 |
| UC Berkeley | 12% | $98,455 |
| UCLA | 9% | $97,701 |
| Cal Poly SLO | 30% | $97,466 |
| Purdue University | 50% | $94,000+ |
Cal Poly SLO produces mechanical engineers earning $97,466 at a 30% admit rate and $31,000 OOS tuition. Cal Maritime and SUNY Maritime both outpace most of the Ivy League for mechanical engineering -- at state school prices and 79-99% admit rates.
What's Driving These Gaps
Three factors explain most of the variance in same-major earnings:
1. Network and employer access. Schools with deeper recruiting relationships with top tech companies, financial firms, and consulting firms place graduates into higher-paying jobs directly. CMU CS grads go to Google and Meta at higher rates than graduates from less-connected schools -- and the salary distribution reflects it.
2. Geographic sorting. Nursing grads in California earn more because California pays more. Business grads in New York earn more because Wall Street is in New York. Choosing a school in a high-wage metro for your intended industry has a compounding effect.
3. Selectivity signaling (but not as much as you'd think). The signal from attending a selective school is real -- but accessible schools like Rose-Hulman, SUNY Maritime, and BYU punch well above their selectivity weight in earnings outcomes.
The Practical Implication
For most majors, the salary gap between the median school and the top schools is large enough to outweigh even significant tuition differences. A student paying $40,000 in annual tuition at a school whose CS graduates earn $115,000 will catch up within two years to a student who paid $25,000 at a school whose CS graduates earn $70,000 -- and then pull ahead for the rest of their career.
The data doesn't argue that every student should chase the most selective school. It argues that for specific majors in specific regions, some schools have dramatically better outcomes than others -- and that "I'm studying CS, so I'll be fine anywhere" is not supported by the actual numbers.
Methodology
Earnings figures are median annual earnings four years post-graduation from federal College Scorecard data (2023 release), reported at the program level. Only programs with 15 or more graduates were included to ensure statistical reliability. Earnings at 1 year post-graduation are not included in major comparisons (significant graduate school enrollment suppresses those figures for many majors). Admission rates are from IPEDS and CDS data. All dollar figures are nominal.
