Her first year, my D22 lived in a classic triple with a 19p meal plan annd our all-in cost was around $28k. We did not use the UC insurance ($3kish savings), we didn’t pay much for books (maybe $300 tops—a lot of teachers use downloadable PDFs or things other than textbooks), and she paid for her social life expenses. This year she was in a plaza with shared bath and 19p, it was a couple thousand more. We do fly her home to the Bay Area a couple times a year at around $400 per trip, including Ubers. Next year, she will be off campus in an Westwood apartment with 5 other girls, her share will be about $1000 per month, plus utilities and food. Not sure what to expect on that budget, but I’m guessing around $600 a month. She will probably shop at Trader Joe’s a lot.
