The short answer
Southern Illinois University-Carbondale civil engineering graduates earn less than graduates of most civil engineering programs nationally, $65,269 in their first year.

Debt is low, but pay is also below the Illinois median of $70,535.

What graduates earn over time
Pay rises about 20% between the first and fifth year.
Year 1 and year 5 figures come from different graduating classes, so the growth rate is an estimate.
Paying back the loans
On a standard 10-year plan, the median debt means a payment of about $210 a month, or 3.9% of a graduate's typical monthly pay in the first year.
The government publishes these as ranges to protect privacy. They were measured in 2018 to 2020, partly during the pandemic pause on federal loan payments, so the forbearance share may be higher than usual.
Where graduates work, and what the pay is worth
61% of graduates (25 of 41) were working in Illinois one year after graduating. Prices in the parts of Illinois outside metro areas are about 13% below the national average, so a $65,269 salary here buys what about $74,661 buys in a typical US city.

About this data
- Earnings and debt only include students who received federal financial aid (grants or loans).
- Earnings only count graduates who were working and not enrolled in more school. Graduates who went straight to further study are not included.
- Debt only includes federal loans. Private loans and credit cards are not counted.
- Some schools with several campuses report one combined figure for all of them. We count each of those schools once, and leave them out of Illinois comparisons when their main campus is in another state.
- Scorecard figures describe graduating classes from several years ago. BLS wages are from May 2025.
- School-level numbers like tuition, admission rate, and graduation rate are for the whole school, not the civil engineering program.
