Civil Engineering at Southern Illinois University-Carbondale
Bachelor's Degree
Analysis
Southern Illinois University-Carbondale's Civil Engineering program sits in the bottom half of both national and state rankings, but the debt picture tells a more favorable story. At $19,781 in median debt—well below both the state median of $23,328 and national median of $24,500—graduates face monthly loan payments roughly $40-50 lower than typical engineering students. The first-year salary of $65,269 trails the state median by about $5,000 and puts this program in the 40th percentile among Illinois engineering schools, but that debt-to-earnings ratio of 0.30 remains manageable for an engineering degree.
The 9% earnings growth to $71,341 by year four suggests reasonable career progression, though graduates still earn less than peers from Illinois' flagship programs. For context, University of Illinois Urbana-Champaign graduates start about $8,000 higher. However, SIU-Carbondale's 90% admission rate and more modest academic profile mean it serves a different student population—one that might not have access to more selective programs.
For families prioritizing low debt over maximum earning potential, this program delivers engineering credentials without excessive borrowing. The tradeoff is clear: you're accepting below-average starting salaries in exchange for significantly lower debt burden. If your student is considering between this and private alternatives with higher sticker prices, SIU-Carbondale offers decent protection from overleveraging. If they can gain admission to U of I or Bradley, though, those programs' higher earnings would likely justify any additional modest debt.
