The Analysis
Verdict
Duke University and Purdue University are close on paper, but Duke University wins the head-to-head, leading on 4 of the core measures (selectivity, cost, earnings, completion, mobility, and debt). The right pick still depends on how you weight them.
Getting in
Duke University is the harder admit. It takes 6% of applicants, while Purdue University takes 50%. Its entering class also posts the higher average SAT, 1,548 to 1,364.
So what: If test scores and a high-scoring peer group matter to you, Duke 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, Purdue University comes out ahead. Its average net price after aid is $14,600, about $15,012 a year below Duke University's $29,612. Graduates of Duke University also borrow less: median debt of $13,000, against $19,500.
So what: Over four years, the gap adds up to about $60,048 before any change in aid. Choosing Purdue University leaves that money available for graduate school, savings, or simply less borrowing.
What graduates earn
Ten years after enrollment, Duke University graduates report median earnings of $97,800, compared with $72,424 at Purdue University. That is a 35% advantage. Set against borrowing, Duke University has the lower debt-to-earnings ratio, 0.13x to 0.27x.
So what: An earnings gap of 35% 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
Duke University graduates a larger share of its students, 96% versus 83%. More of its students stay on track to a degree.
So what: A completion gap of 13% 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 Purdue University to keep costs and debt down; pick Duke University for the higher earnings ceiling.
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
The cheaper school is not the lower-earning one here. Purdue University saves about $15,012 a year, yet Duke University graduates earn $25,376 more ten years after enrollment. The cost advantage and the earnings premium sit at different schools, so your time horizon decides which counts more.
Their academic identities diverge. Duke University concentrates enrollment in Social Sciences, Biology & Biomedical, while Purdue University leans toward Business & Marketing, Computer Science & IT. That split shapes which recruiters come to campus and what your classmates study.
Who Should Look Elsewhere
- Cost-conscious students: net price of $29,612 runs well above Purdue University's $14,600.
- Business and consulting-track students: Duke University has less business program depth, and Purdue University offers the stronger options.
- Students minimizing debt: median debt is $19,500, against $13,000 at Duke University.
- Students who want a smaller campus: Purdue University's enrollment of 44,503 far exceeds Duke University's 6,442.
