* In-state vs. out-of-state tuition: Out-of-state students pay significantly more.
* Student's living situation: On-campus housing and meal plans add substantial costs. Living off-campus will vary widely based on location and housing type.
* Personal spending: Books, supplies, transportation, and personal expenses differ from student to student.
Therefore, there's no single answer to "how much does one year of school cost." To get an accurate estimate, you should visit the Chico State website and use their cost calculator or review their tuition and fee schedules for both in-state and out-of-state students. They will likely provide breakdowns of tuition, fees, housing, and meal plan costs, allowing you to build a personalized estimate.
