Here are some NPC results assuming dependent California resident student living with 1 divorced parent with $20,000 income:
UCB: $9,000 on/off campus, $8,800 commuter, https://saservices.berkeley.edu/calculator/
UCSB: $10,000, https://www.finaid.ucsb.edu/net-price-calculator
UCR: $11,676 on campus, $9,613 off campus, $8,343 commuter, http://vcsaweb.ucr.edu/finaidmanualcalculator/
SDSU: $13,247 on campus, $11,125 off campus, $-136 commuter, http://studentaffairs.sdsu.edu/ofas2/NPCC/npcalc.htm
SJSU: $12,824 on campus, $12,108 off campus, $-1,288 commuter, https://vpsaweb2.sjsu.edu/faso/netpricecalc/npcalc.htm
- = estimates $0 room and board costs for commuters, even though food and utilities at parent's house cost more than $0.
Actual costs for off campus and commuter situations can vary greatly, so it is possible that a student living off campus or commuting from parent’s house could have significantly higher or lower net price than the estimate, even if financial aid is as predicted.
