The Analysis
Verdict
Purdue University and University of California-San Diego are close on paper, but University of California-San Diego 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
University of California-San Diego is the harder admit. It takes 27% of applicants, while Purdue University takes 50%.
So what: If test scores and a high-scoring peer group matter to you, University of California-San Diego 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 $2,130 a year below Purdue University's $14,600. Graduates of University of California-San Diego also borrow less: median debt of $15,500, against $19,500.
So what: Over four years, the gap adds up to about $8,520 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 California-San Diego graduates report median earnings of $84,943, compared with $72,424 at Purdue University. That is a 17% advantage. Set against borrowing, University of California-San Diego has the lower debt-to-earnings ratio, 0.18x to 0.27x.
So what: An earnings gap of 17% 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 California-San Diego graduates a larger share of its students, 87% versus 83%. More of its students stay on track to a degree.
So what: A completion gap of 4% 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.
