Analysis
A first-year salary around $40,000 for a physics-focused bachelor's degree tells an important story about STEM's reality beyond the headlines. While comparable astronomy and astrophysics programs across California show a median of $45,000—and Berkeley's graduates command $55,000—this estimate based on similar national programs suggests SDSU's outcomes may fall short of the state's stronger performers. The estimated debt load of $21,400 is actually below the national median for this field, which offers some reassurance about affordability.
The debt-to-earnings ratio here looks manageable on paper, but the real question is what comes next. Astronomy and astrophysics bachelor's degrees rarely lead directly to research careers—most graduates either pursue graduate school (where stipends replace salaries for years) or pivot to adjacent fields like data science, engineering, or teaching. That $40,000 starting point matters less if your child plans to continue their education, but it's sobering if they're hoping to launch a career immediately after graduation.
For families weighing this program, the key issue isn't the estimated debt—it's understanding whether your child has a clear path beyond the bachelor's degree. If graduate school is the plan, SDSU's lower debt burden compared to the national average could actually be an advantage. If they're hoping to work right away, they should explore how SDSU connects astronomy majors to jobs in California's robust tech and aerospace sectors.

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 San Diego State 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 national median of 6 similar programs. Actual outcomes may vary.
