SECURE 2.0 Changed the Calculus
The SECURE 2.0 Act of 2022 was arguably the most significant policy change for 529 plans since their creation. Beginning in 2024, families can roll unused 529 funds into a Roth IRA for the same beneficiary (up to $35,000 lifetime, subject to a 15-year account age requirement). This eliminated the long-standing "what if my child doesn't go to college?" objection that kept many families from opening accounts.
The impact is showing up in the data: net inflows reached $3.5 billion in Q4 2025, up from $3.0 billion a year earlier. And estimated Q1 2025 inflows of $2.2 billion exceeded Q1 2023 levels by 38%.
Steady Account Growth, Accelerating Assets
Account growth has been remarkably steady at 3–4% per year. The number of accounts rose from 10.1 million in 2009 to 17.7 million in 2025, adding roughly 500,000 accounts annually. But asset growth has been far more volatile, driven by market returns. The 2022 bear market wiped $69 billion off plan values (from $480B to $411B), only for markets to recover and push assets to new highs by late 2024.
This pattern underscores that 529 asset totals are primarily driven by investment returns on existing balances rather than new contributions alone. With 38% of accounts now receiving automatic contributions, the savings behavior has become more resilient even during downturns.
Concentration Among a Few Plans
The 529 market is heavily concentrated. The five largest plan managers (Ascensus ($157B), American Funds ($109B), TIAA ($69B), Fidelity ($56B), and Utah ($30B)) collectively hold about 70% of all 529 savings assets. Virginia alone accounts for over $105 billion, largely through its CollegeAmerica plan managed by American Funds.
This concentration means that the investment choices, fee structures, and marketing budgets of a handful of firms shape the college savings experience for the majority of American families.
Expanded Use Cases
529 plans are no longer just for four-year colleges. Legislative changes have expanded eligible expenses to include K-12 tuition (up to $10,000/year since 2018), registered apprenticeships, vocational programs, and student loan repayment (up to $10,000 lifetime). The Roth IRA rollover provision further broadened their appeal.
These expansions have transformed 529s from a narrow college savings tool into a more flexible education and early-career investment vehicle, likely contributing to the sustained account growth.
What the Data Doesn't Show
While 17.7 million accounts sounds impressive, it represents only a fraction of American families. Roughly 54% of parents remain unaware of 529 plans, and participation skews heavily toward higher-income households. The median 529 account balance was just $9,500 in Q4 2025 (far below the $34,062 average) reflecting a long tail of smaller accounts alongside a smaller number of well-funded ones.
For the $500K+ net worth segment, 529 plans represent a meaningful but modest piece of the wealth picture, $600 billion is less than 0.4% of total household net worth.
A $600 Billion Milestone
529 plans crossed $600 billion in total assets for the first time in Q4 2025, reaching $602.9 billion across 17.7 million accounts. That represents a 14.8% increase over year-end 2024 and a nearly 6x increase from the $105 billion held in 2008. The growth reflects both strong equity market returns and steady net inflows as more families adopt these tax-advantaged vehicles.
The average account value hit $34,062 at the end of 2025, up from just $13,188 in 2009, a compound annual growth rate of roughly 6% over 16 years.
