Parents of a 5-year-old want to fully fund 4 years at Ohio State University (current cost ~$31,000/year in-state including room/board). They're opening a 529 plan today.
Takeaway: Ohio's 529 (CollegeAdvantage) provides a state tax deduction up to $4,000/yr per beneficiary — worth ~$190/yr at Ohio's 4.75% rate. If the child gets a scholarship, up to $10,000 can be rolled to a Roth IRA penalty-free under 2024 SECURE Act rules.
Using general 2-3% inflation to project future tuition underestimates costs. Published tuition at 4-year public universities has increased at roughly 4-5% annually for 20 years. Private schools run 3-4%. A $30,000/year school today costs ~$50,000/year in 13 years at 4% education inflation.
All 529 plans offer age-based portfolios that shift toward bonds as college approaches. Expense ratios vary from 0.05% (Utah's my529) to 0.9%+ in some state plans. You can use any state's 529 regardless of where your child attends college — your own state's plan is only worth it if it offers a state tax deduction.
Parent-owned 529 assets count as 5.64% toward Expected Family Contribution (EFC) in FAFSA. Student-owned assets count as 20%. High 529 balances reduce need-based aid dollar-for-dollar above your EFC threshold. For families close to aid cutoffs, this interaction matters significantly.
Tuition gets the attention, but room and board at a typical residential university adds $12,000-$18,000/year. Total cost of attendance including books and personal expenses runs $32,000-$80,000/year depending on institution type. Make sure your projection uses total COA, not tuition alone.

The power of compound growth makes starting early the single most important college savings decision. A family that starts saving $300/month when their child is born, earning 7% annually, will have approximately $130,000 by age 18. Wait until the child is 5, and that same $300/month grows to only $82,000. Wait until 10, and it is just $49,000. Starting at birth gives you 18 years of compound growth — the difference between fully funding a state university education and covering less than half. Even small amounts matter: $100/month from birth grows to roughly $43,000, enough to cover nearly two years at an in-state public university.
College costs have risen at roughly 5% per year over the past two decades, significantly outpacing the 2-3% general inflation rate. For the 2024-25 academic year, average annual costs including tuition, fees, room, and board are: $23,250 for in-state public universities, $41,920 for out-of-state public universities, and $58,600 for private universities. At 5% annual inflation, a child born today would face estimated costs of: $56,000/year for in-state public (total: $224,000 for 4 years), $101,000/year for out-of-state public (total: $404,000), and $141,000/year for private (total: $564,000). These numbers are staggering, but financial aid, scholarships, and strategic planning can significantly reduce the net cost.
A 529 plan is a state-sponsored investment account designed for education savings. There are two types: savings plans (investment accounts, by far the most common) and prepaid tuition plans (lock in current tuition rates at specific state schools). With a savings plan, you contribute after-tax dollars into investment portfolios. The money grows tax-free federally, and withdrawals for qualified education expenses — tuition, required fees, room, board, books, supplies, computers, and internet — are also tax-free. Qualified expenses now include K-12 tuition (up to $10,000/year), registered apprenticeship costs, and student loan repayment (up to $10,000 lifetime per beneficiary).
Over 30 states offer income tax deductions or credits for 529 contributions. The benefit varies: some states offer unlimited deductions, while others cap at $2,000-$10,000 per taxpayer. A family in a state with a 5% income tax rate saving $5,000/year gets a $250 annual tax benefit — or $4,500 over 18 years before considering the investment growth on those tax savings. Some states offer tax benefits only for contributions to their own state plan, while others (like Arizona, Kansas, Maine, Missouri, Montana, and Pennsylvania) allow deductions for contributions to any state's plan. Choose the plan with the best combination of tax benefit and investment options.
Most 529 plans offer age-based portfolios that automatically shift from aggressive (more stocks) to conservative (more bonds) as the child approaches college age. This is generally the best choice for most families. A typical age-based portfolio might be 80-90% stocks when the child is 0-5, shifting to 60-70% stocks at ages 6-10, 40-50% at ages 11-14, and 20-30% at ages 15-18. The goal is to maximize growth during the early years when you have time to recover from market downturns, while protecting against losses as college approaches. Avoid being too conservative early on — a 529 invested entirely in bonds from birth would grow to roughly half the amount of a balanced stock/bond portfolio over 18 years.
Financial planners often recommend the one-third rule: save enough to cover one-third of projected costs, plan to pay one-third from current income during the college years, and expect one-third to come from financial aid, scholarships, and student loans. This makes the savings target more manageable. For a student heading to an in-state public university (projected 4-year cost of approximately $110,000 at today's inflation trends for a child born today), the savings target would be roughly $37,000. At 7% annual returns, that requires about $100/month from birth. Most families can find $100/month through small lifestyle adjustments — skipping one family dinner out per month and making coffee at home.
The SECURE 2.0 Act introduced a provision allowing unused 529 funds to be rolled over to a Roth IRA in the beneficiary's name. The rules: the 529 must have been open for at least 15 years, annual rollovers are subject to Roth IRA contribution limits ($7,000 in 2024 for those under 50), the lifetime maximum is $35,000, and contributions made in the last 5 years (plus their earnings) cannot be rolled over. This eliminates one of the biggest concerns about 529 plans — the fear of overfunding. If your child earns a scholarship or chooses a less expensive school, the excess can start their retirement savings tax-free.
Coverdell Education Savings Accounts (ESAs) allow $2,000/year in contributions with tax-free growth, but phase out at higher incomes. Custodial accounts (UGMA/UTMA) have no contribution limits but the money belongs to the child at 18-21 and counts heavily against financial aid. Taxable brokerage accounts offer flexibility but no tax advantages. Roth IRAs can be used for education (contributions can be withdrawn penalty-free) but reduce retirement savings. I Bonds (up to $10,000/year per person) offer inflation protection and can be tax-free for education if you meet income limits. For most families, a 529 plan remains the best primary vehicle, potentially supplemented by one or more of these alternatives.
Average annual costs for 2024-25: $11,610 for in-state public university (tuition and fees), $24,030 for out-of-state public, and $43,350 for private. Including room and board, totals average $23,250 (in-state), $41,920 (out-of-state), and $58,600 (private).
A 529 plan is a tax-advantaged savings account for education expenses. Contributions grow tax-free, and withdrawals for qualified expenses (tuition, room, board, books) are also tax-free. Many states offer additional state tax deductions for contributions.
A common approach is to cover 1/3 from savings, 1/3 from income during college, and 1/3 from aid/loans. For a public university, this means saving roughly $200-400/month from birth. Starting later requires higher monthly amounts.
Since 2024, unused 529 funds can roll over to a Roth IRA for the beneficiary (up to $35,000 lifetime limit, subject to annual Roth limits). You can also change the beneficiary to another family member or withdraw with a 10% penalty on earnings.
Parent-owned 529 plans are treated as parental assets on FAFSA, reducing aid by at most 5.64% of the balance. A $50,000 account reduces aid by about $2,800. This is much less impactful than student-owned assets (20% reduction).
A 529 plan is a tax-advantaged savings account for education expenses. Contributions grow tax-free and withdrawals are tax-free when used for qualified education costs including tuition, fees, room, and board. Most states also offer state tax deductions for contributions.
For a child born today, saving $300-$500 per month at 7% returns will accumulate $130,000-$215,000 by age 18. This covers roughly 50-80% of projected costs at a public university. Start as early as possible to maximize compound growth.
Unused 529 funds can be transferred to another family member including siblings, cousins, or even yourself. Starting in 2024, up to $35,000 of unused 529 funds can be rolled into a Roth IRA for the beneficiary after the account has been open for 15 years.
Yes, anyone can contribute to a 529 plan regardless of relationship to the beneficiary. Grandparents can contribute up to $18,000 per year per beneficiary without gift tax implications, or superfund up to $90,000 as a five-year gift tax election.
529 plans offer tax-free growth and withdrawals for education, making them superior for dedicated college savings. Regular investment accounts offer more flexibility but gains are taxable. Use a 529 for the bulk of college savings and taxable accounts for overflow.
