The Analysis
Verdict
University of California-San Diego and University of Pennsylvania are close on paper, but University of Pennsylvania wins the head-to-head, leading on 3 of the core measures (selectivity, cost, earnings, completion, mobility, and debt). The right pick still depends on how you weight them.
Getting in
University of Pennsylvania 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, University of Pennsylvania 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, University of California-San Diego comes out ahead. Its average net price after aid is $12,470, about $16,229 a year below University of Pennsylvania's $28,699. Graduates of University of California-San Diego also borrow less: median debt of $15,500, against $15,715.
So what: Over four years, the gap adds up to about $64,916 before any change in aid. Choosing University of California-San Diego leaves that money available for graduate school, savings, or simply less borrowing.
What graduates earn
Ten years after enrollment, University of Pennsylvania graduates report median earnings of $111,371, compared with $84,943 at University of California-San Diego. That is a 31% advantage. Set against borrowing, University of Pennsylvania has the lower debt-to-earnings ratio, 0.14x to 0.18x.
So what: An earnings gap of 31% 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
University of Pennsylvania 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 10% 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.

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.
