The Analysis
Verdict
Princeton University and University of California-San Diego are close on paper, but Princeton University wins the head-to-head, leading on 5 of the core measures (selectivity, cost, earnings, completion, mobility, and debt). The right pick still depends on how you weight them.
Getting in
Princeton University is the harder admit. It takes 5% of applicants, while University of California-San Diego takes 27%.
So what: If test scores and a high-scoring peer group matter to you, Princeton University sets the higher bar. The less selective school is easier to get into, which can work in your favor rather than against it.
What it costs
On price, Princeton University comes out ahead. Its average net price after aid is $6,128, about $6,342 a year below University of California-San Diego's $12,470. Graduates of Princeton University also borrow less: median debt of $10,320, against $15,500.
So what: Over four years, the gap adds up to about $25,368 before any change in aid. Choosing Princeton University leaves that money available for graduate school, savings, or simply less borrowing.
What graduates earn
Ten years after enrollment, Princeton University graduates report median earnings of $110,066, compared with $84,943 at University of California-San Diego. That is a 30% advantage. Set against borrowing, Princeton University has the lower debt-to-earnings ratio, 0.09x to 0.18x.
So what: An earnings gap of 30% this early in a career tends to widen, since raises build on the higher base. Of the measures on this page, this one carries the most financial weight.
Finishing the degree
Princeton University graduates a larger share of its students, 97% versus 87%. More of its students stay on track to a degree.
So what: A completion gap of 11% is a risk measure. Students at the school with the lower rate face higher odds of leaving with debt and no degree, the most expensive outcome in higher education.
Recommendation
Bottom line: pick Princeton University to keep costs and debt down.
Data certainty: High. Both schools report 5 of 6 core signals used here; where one school is missing a figure, that row is left out of the comparison rather than estimated.
Counterintuitive Insights
Their academic identities diverge. Princeton University concentrates enrollment in Computer Science & IT, while University of California-San Diego leans toward Biology & Biomedical. That split shapes which recruiters come to campus and what your classmates study.
Who Should Look Elsewhere
No strong negative signals — Princeton competes well across the dimensions measured.
- Cost-conscious students: net price of $12,470 runs well above Princeton University's $6,128.
- Students minimizing debt: median debt is $15,500, against $10,320 at Princeton University.
