Analysis
Caltech's elite reputation doesn't translate into standout starting salaries for mechanical engineering graduates—at least not based on what comparable California programs suggest. The estimated $72,400 first-year earnings track with the state median, but fall well short of Cal Maritime's $92,000 or even UC Berkeley's $88,500. For an institution with a 3% admission rate, this puts Caltech's MechE graduates in roughly the middle of the pack salary-wise, a surprising position given the school's prestige.
The financial fundamentals look solid enough. An estimated debt load around $23,500—slightly above the state median but below the national benchmark—paired with those earnings yields a manageable 0.33 debt-to-earnings ratio. Similar programs across California suggest graduates should be able to handle repayment without strain. The relatively low Pell enrollment (15%) indicates most students come from families who can shoulder more of the costs.
Here's the practical question: if your child could get into Caltech's hyper-selective program, they likely have options at Berkeley or Cal Poly SLO, where comparable programs produce noticeably higher early earnings based on actual reported data. The Caltech name carries weight for graduate school and research careers, but for pure return on a bachelor's degree investment in mechanical engineering, the numbers suggest looking hard at those alternatives.

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 California Institute of Technology, approximately 15% 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 26 similar programs in CA. Actual outcomes may vary.
