Analysis
In Illinois, mathematics bachelor's programs typically place graduates around $52,597 in their first year—right where Lewis University's estimated outcome lands. Based on comparable programs at similar institutions in the state, graduates can expect roughly $17,000 in debt, which translates to a debt-to-earnings ratio of 0.32. That's manageable: about four months of gross income to pay off student loans, well below the threshold where debt becomes burdensome.
What's worth noting here is the competitive landscape. While Lewis appears to track with the state median, Illinois hosts mathematics programs with dramatically different outcomes—from DePaul's $55,586 to Northwestern's $79,530 and University of Chicago's six-figure starting salaries. The gap suggests that employer prestige and alumni networks matter considerably in mathematics careers. However, these peer program estimates also indicate that Lewis avoids the debt trap that plagues many private institutions. The estimated $17,000 burden is about $3,500 below the state median and $4,400 below the national benchmark.
For a family evaluating Lewis against other Illinois options, the estimated figures suggest a middle-ground choice: solid earnings potential without excessive debt exposure. The caveat is that these are projections based on similar programs rather than tracked outcomes from Lewis's own mathematics graduates, so actual results could vary. If your child has the credentials for more selective programs, the earnings ceiling may justify exploring those options.

About This Data
Source: U.S. Department of Education College Scorecard (October 2025 release)
Population: Graduates who received federal financial aid (Title IV grants or loans). At Lewis University, approximately 31% of students receive Pell grants. Students who did not receive federal aid are not included in these figures.
Earnings: Median earnings from IRS W-2 data for graduates who are employed and not enrolled in further education, measured 1 year after completion. Earnings are pre-tax and include wages, salaries, and self-employment income.
Debt: Median cumulative federal loan debt at graduation. Does not include private loans or Parent PLUS loans borrowed on behalf of students.
Estimated Earnings: Actual earnings data is not available for this program (typically due to privacy thresholds when fewer than 30 graduates reported earnings). The estimate shown is based on the median of 7 similar programs in IL. Actual outcomes may vary.
