Geological and Earth Sciences/Geosciences at California Polytechnic State University-San Luis Obispo
Bachelor's Degree
Analysis
Cal Poly SLO's geosciences program lands graduates at nearly $50,000 within their first year—roughly $10,000 above the national median and competitive with UC Davis. Perhaps more surprisingly, students graduate with just $15,000 in debt, among the lowest in the nation for this field. That $48,489 starting salary might place the program in the 60th percentile among California geology programs, but given the minimal debt burden, the return on investment actually outpaces flashier names.
The debt-to-earnings ratio of 0.31 means graduates owe less than four months' salary, giving them unusual financial flexibility for a field that often requires graduate work or field seasons with modest pay. Compare this to the national picture: most geology graduates carry $24,757 in debt while earning $39,678—nearly double the debt for $9,000 less in earnings. Even within California, where the median debt is $17,896, Cal Poly manages to keep costs notably lower.
For families weighing Cal Poly's selective admission process (30% acceptance rate), the financial equation is straightforward. Your child enters a hands-on program at a polytechnic known for practical training, graduates with manageable debt, and earns competitively from day one. That's a foundation that supports whatever comes next—whether that's immediate employment in environmental consulting or the financial breathing room to pursue graduate studies.
