See how your education savings could grow — tax-free, until it's time for college
💡 Why This Matters College costs keep climbing, and 529 plans grow tax-free when used for education. See what steady contributions today could realistically turn into by the time your child starts school.
Every state offers at least one 529 plan, but you're not limited to your own state's plan — you can shop around for better fees or investment options, though you may lose a state tax deduction by doing so.

A 529 grows the same way any investment account does: your current balance compounds at your entered average return, and each monthly contribution compounds for the months remaining until college. The calculator adds your starting balance's projected growth to the combined growth of every future contribution to arrive at your total projected balance.
The projected balance is your estimate of what will be available when your child starts college, assuming steady contributions and a consistent average return. The breakdown separates what you actually put in from what growth added — and since qualified 529 withdrawals are federal-tax-free, that growth portion is money you keep in full, not money you'll owe taxes on later.
Market returns aren't linear — real 529 investments (especially age-based portfolios that shift to conservative holdings as college nears) will have up and down years even if the long-term average matches your estimate. This also assumes contributions stay consistent, which real budgets don't always allow, and doesn't account for the specific fee structure of your plan.
If your projected balance falls short of expected college costs, try increasing the monthly contribution or starting earlier — even small increases compound meaningfully over a decade-plus timeline. Check whether your state offers a tax deduction for 529 contributions, since that can effectively boost your real return beyond the account's investment performance alone.
Example: Say you start a 529 with $5,000, contribute $250 every month, and earn a 6% average annual return over 15 years until college. Your balance and each contribution compound monthly — add it up and you'd have $84,975.15. Of that, $50,000 came from your own contributions and $34,975.15 came from tax-free growth.
The same way any investment account grows: your starting balance compounds at your entered average return, and each monthly contribution compounds for the months remaining until your target date. The total is your starting balance's growth plus the combined growth of every contribution.
Withdrawals are federal-tax-free when used for qualified education expenses like tuition, room and board, and books. Many states also offer a tax deduction or credit for contributions. Non-qualified withdrawals can trigger taxes and a penalty on the earnings portion, so it's worth checking your state's specific rules.
Most 529 plans use age-based portfolios that start more aggressive and shift conservative as college approaches, so a blended long-term average (often 5-7%) is a reasonable estimate rather than a single year's return. Check your specific plan's historical performance for a more tailored number.
You can change the beneficiary to another family member, use the funds for the account owner's own education, or roll a limited amount into a Roth IRA for the beneficiary under recent rule changes. Non-education withdrawals are subject to tax and penalty on earnings, so it's rarely the first option.
