How we worked these out
The family
A family of four with good parent credit and $500 a month to put toward college, and the savings you pick. In state, the grants are what California State University-San Marcos reports families at that income got, on average. Your own will differ, and a family with no aid pays close to the full price. Out of state, there are no grants: the price is before any scholarship from the college.
What a SmartTuition plan saves
The difference, over four years, between a SmartTuition plan and the standard approach: savings first, then loans for the rest. It counts loan interest and the federal tax credit.
The $6,400 in the “Pay less for college” box near the top of this page is the median saving in California State University-San Marcos's own scenarios. Each scenario is a household that lives in California, with an income from $45,000 to $200,000 and savings of none, $40,000 or $100,000 in a 529. We price California State University-San Marcos at the aid it reports for that income.
Every scenario has parents with good credit and $500 a month toward college. The card above uses the same two. A scenario where the parents would borrow more than $65,000 is left out.
The prices by income
- They describe students who got aid.
- “Over $110,000” has no upper limit, so it averages families just over $110,000 with far wealthier ones. A family at $115,000 should expect to pay less than it shows.
- Each range is reported on its own, so the prices do not always rise with income.
Where the prices come from
Where the prices come from: California State University-San Marcos's own 2026-27 tuition, fees, housing, food and books, from its website, carried forward to 2027 at 3.0% a year. The grants are the U.S. Department of Education's College Scorecard (2025-26 figures), carried forward the same way. Each price after grants is the cost less those grants. The out-of-state figure uses the published out-of-state tuition instead. The average price after grants counts the students who get federal aid. Your own figure will be different.
California State University-San Marcos's own budget for 2026-27 is $30,866. It also counts costs the university doesn't bill for, such as travel and personal spending. We leave those out.
