529 College Savings Calculator

Calculate how much you need to save for college with tax-advantaged 529 plan growth. With college costs rising faster than inflation, early planning and consistent saving are essential for helping your children graduate without crushing student loan debt. This calculator shows how tax-free compound growth can make college more affordable.

Understanding 529 Plans

A 529 plan is a tax-advantaged investment account designed specifically for education expenses. Contributions grow tax-free, and withdrawals are tax-free when used for qualified education expenses. Many states also offer tax deductions or credits for contributions, creating triple tax benefits—deduction now, tax-free growth, and tax-free withdrawals.

Unlike IRAs, 529 plans have no income limits and very high contribution limits (often $300,000+ per beneficiary). You can change beneficiaries within the family, and starting in 2024, unused funds can be rolled into a Roth IRA under certain conditions.

The numbers can be daunting, but remember: financial aid, scholarships, and your 529's investment growth all help bridge the gap.

Starting early dramatically reduces monthly savings requirements. At birth, compound growth does most of the work.

Frequently Asked Questions

How much should I save in a 529 plan?

A common target is 1/3 of expected college costs. For a state school ($25k/year), save ~$33k per child. For private ($55k/year), target ~$73k. The earlier you start, the less you need to save monthly due to compound growth.

What are 529 plan tax benefits?

529 plans offer tax-free growth and tax-free withdrawals for qualified education expenses. Many states also offer tax deductions or credits for contributions. Earnings on non-qualified withdrawals face income tax plus 10% penalty.

What happens to 529 funds if my child doesn't go to college?

You can change the beneficiary to another family member, use funds for trade school or apprenticeships, roll up to $35k into a Roth IRA (after 15 years), or withdraw with taxes and 10% penalty on earnings only.
