ROI Score: 80/100 · Strong Value
California State University-San Marcos (CSUSM) is a public university in San Diego County, California, enrolling approximately 14,877 students. Its ROI score of 80 places it in the Strong Value tier—notable for a CSU campus serving a predominantly commuter student body. In-state tuition is just $8,082, and the average net price is $10,229, making the four-year total estimated cost $40,916—one of the lowest cost profiles in this cohort. Six-year median earnings of $40,500 and ten-year earnings of $62,908 reflect a broad program mix spanning nursing, STEM, business, and liberal arts. The payback period of 6.5 years is efficient. The earnings premium score of 95 out of 100 is exceptional, suggesting CSUSM graduates significantly outperform their baseline expectations given the student population served. Median debt of $17,350 and a debt-to-earnings ratio of 0.428 are well-controlled. The completion rate of 54.6% is the institution's most notable weakness, reflecting challenges that many regional comprehensive universities face with first-generation and commuting students. Pell Grant recipients make up 42.6% of the student body. The strong earnings premium combined with low cost makes CSUSM a legitimately strong public-sector value despite completion challenges.

The sticker price at California State University-San Marcos is $8,082/year ($20,682/year out-of-state). But sticker price isn't what most students pay. After grants, scholarships, and financial aid, the average student pays a net price of $10,229/year, or roughly $40,916 over four years.
That net price varies significantly by family income. The lowest-income families (under $30,000/year) pay an average of $6,230/year, while families earning over $110,000 pay $18,734/year.

Cost by Income Bracket Explained
Lower-income families (under $30K)
Students with family incomes below $30,000 pay an average net price of $6,230 per year—roughly $24,920 over four years. Against a 6.5-year payback and nursing year-one earnings above $100,000, this is among the most favorable access-to-outcome ratios in the California public system. Even in lower-earning majors, the debt load is structurally manageable.
Middle-income families ($30K-$110K)
Middle-income families ($30,001–$75,000) face net prices of $7,240–$8,928. These figures are extremely competitive relative to outcomes. CSUSM offers middle-income students the cost efficiency of a community college at a level of career preparation and degree recognition comparable to larger CSU campuses.
Higher-income families ($110K+)
Higher-income families ($75,001 and above) pay $12,525–$18,734 per year. Even at the top of the income scale, CSUSM is priced well below comparable private institutions in San Diego. For high-income families concerned about peer networks or national brand recognition, Cal Poly SLO or UC San Diego provide an alternative, but CSUSM's value proposition remains strong on pure ROI grounds.
