How the 529 college savings calculator works

The account grows with monthly contributions at your assumed return. College cost inflates at the college inflation rate until your child enrolls and for four years of attendance.

Example

Using the default inputs (Child’s age: 3; Current 529 balance: $5,000; Monthly contribution: $300; Annual return: 6%; Annual college cost today: $28,000; …), the calculator returns projected 529 balance at 18 of $99,516. Change any field above to see your own result and charts update instantly.
