Reading this: Total cost is what the schools take; 529 after grad is what survives; anything left mostly cannot become an IRA (only the → Roth column can). A large "529 left at end" means over-funding — money locked behind education-only withdrawal rules, a future grandkids fund, or a taxed + 10%-penalty exit.
