This tool does not provide financial, investment, tax, legal, or accounting advice, and using it does not create any advisory or professional relationship. It is a self-service calculator for general educational and informational purposes only. Nothing it displays should be taken as a recommendation to take — or not take — any particular action, including whether to open a 529 plan, a Trump Account, or a brokerage account, which state's plan to choose, how much to contribute, or how to invest. This tool also sells nothing — it runs no ads and has no affiliate, referral, or sponsorship relationships with any 529 plan, brokerage, bank, or financial company, so it earns nothing from what you decide and has no incentive to steer you toward any product or provider.
Every figure is a projection built from the inputs you provide (ages, costs, contributions, expected returns, tax rates, and other assumptions) using simplified math. Real life differs: investment returns vary year to year and can be negative, age-based 529 portfolios shift more conservative as college nears, college costs at a specific school can rise faster or slower than any average, and tax outcomes depend on your full situation. The account comparison makes simplifying assumptions (identical returns across accounts, current tax law, the "kiddie tax" treatment of a dependent student's investment income) that may not match your circumstances. Actual results will differ. No accuracy, completeness, or outcome is promised, and the calculations may contain errors.
The state deduction and credit figures are a good-faith summary of 2026 rules gathered from public sources in July 2026. States change these rules, and most have fine print — income limits, per-beneficiary versus per-taxpayer caps, carryforward provisions, recapture on non-qualified withdrawals — that a one-line summary cannot capture. Always confirm with your state's plan documents or tax authority before relying on a deduction or credit.
For large or irreversible choices — superfunding, account type, beneficiary changes — consider a fee-only fiduciary advisor or a CPA who is paid for advice rather than for selling a product.
This is an independent, privately made tool. It is not created, endorsed, sponsored, or reviewed by any government agency, state 529 plan, brokerage, or financial company. "Trump Account" is used only to describe the federal savings account created by 2025 legislation; "529" refers to Section 529 of the Internal Revenue Code.
