Why college inflation breaks every intuition
US college costs have grown 5–8% annually — about 2× general inflation. A $30k/year school today will cost around $50k/year in 10 years.
529 plans grow tax-free for qualified education expenses. Many US states also give a state income tax deduction — free money for saving.
Overfunding is not a disaster. Since 2024, up to $35k of unused 529 funds can roll to a Roth IRA for the beneficiary (subject to rules).
