529 College Savings Calculator
Enter what you have saved, what you add each month and the years until college to see the projected 529 balance, how much of the cost it covers and the gap left. The growth math is the same in every state; $300 a month for 10 years at 7% reaches $51,925. Where you live changes only the state tax deduction, listed below for the states whose statute we read.

How this calculator works
The balance grows with monthly contributions compounded at the return you enter, from today's balance to the first year of college. The cost starts at the yearly figure you enter for the first year of college, and each later year is 5% higher than the one before (a planning assumption, not a published tuition forecast): 4 years starting at $25,000 come to $107,753. Prices are not raised for the years before college starts, so enter the first-year cost you expect then. Coverage is the projected balance divided by that total, and the shortfall is what is left to pay. Earnings in a 529 grow free of federal tax and come out tax-free for qualified education expenses. A state income tax deduction or credit is a separate saving that does not change the balance; the state table on this page lists each state's rule where it was read from the statute.

Deductions lower state taxable income, so they save your state rate on the amount deducted; a credit, such as Minnesota's alternative to its subtraction, is worked out on the state form instead. Federal law gives no deduction for contributions.

Frequently Asked Questions
How much will a 529 grow?
$300 a month for 10 years at 7% grows to $51,925: $36,000 you put in and $15,925 of growth. Against 4 years of college starting at $25,000 a year and rising 5% a year ($107,753 in all), that covers 48% and leaves $55,828 to find. Returns are not guaranteed; try a lower rate too.
Do I get a state tax deduction for 529 contributions?
It depends on your state, and some states only allow it for their own plan. The state table on this page gives the rule for the 12 states whose statute was read on 2026-10-11. Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming have no broad income tax, so there is nothing to deduct. For the rest, check your state's plan or revenue department before you count on a deduction.
