How the 529 Plan Growth Calculator Works
A 529 plan lets your education savings grow tax-free, and many states offer a tax deduction for contributions. This calculator projects your balance at the time you’ll need the funds.
This 529 growth calculator computes:
- Projected Balance at College — your estimated total when funds are needed
- Total Contributions — money you put in over time
- Total Tax-Free Growth — investment gains, untaxed
- Annual & Total State Tax Savings — estimated deduction benefit
529 Plan Growth Formula
Balance = P × (1 + r/12)^(12×t) + PMT × [((1 + r/12)^(12×t) − 1) ÷ (r/12)]
Where: - P = Current 529 balance - PMT = Monthly contribution - r = Expected annual return (as a decimal) - t = Years until college
