The cost of a four-year college degree has risen 5–8% annually for decades — far faster than general inflation. A year at an in-state public university costs approximately $28,000 in 2026 (tuition, room, and board). At a private university, it's closer to $60,000.
For parents of young children, these numbers will be even higher by the time their kids enroll. A 529 plan is the most tax-efficient way to save, offering tax-free growth and withdrawals for education expenses.
How 529 Plans Work
A 529 plan is a state-sponsored investment account where contributions grow tax-free and withdrawals for qualified education expenses are also tax-free. Over 30 states offer additional state income tax deductions for contributions.
Qualified expenses include tuition, fees, room and board, books, supplies, computers, and up to $10,000/year for K-12 tuition. New for 2024+: unused 529 funds can be rolled into a Roth IRA for the beneficiary (up to $35,000 lifetime, after 15 years).
Projecting the True Cost of College
Parents consistently underestimate future college costs. At 5% annual inflation, today's $28,000/year public university becomes:
- In 5 years: ~$35,700/year ($142,800 for 4 years)
- In 10 years: ~$45,600/year ($182,400 for 4 years)
- In 15 years: ~$58,200/year ($232,800 for 4 years)
- In 18 years (newborn): ~$67,300/year ($269,200 for 4 years)
The Power of Starting Early
Time is the most powerful factor in college savings. Consider two families saving for the same $200,000 college fund at 7% annual return:
- Family A starts at birth: Needs ~$460/month for 18 years. Total contributions: ~$99,000. Investment growth covers the rest.
- Family B starts at age 8: Needs ~$1,100/month for 10 years. Total contributions: ~$132,000.
- Family C starts at age 13: Needs ~$2,900/month for 5 years. Total contributions: ~$174,000.
Choosing the Right 529 Plan and Investments
You can open a 529 plan in any state, regardless of where you live. Steps to choose:
- Check your state's tax benefit. Over 30 states offer income tax deductions or credits for 529 contributions. If your state does, start there.
- Compare fees. Total annual costs range from 0.10% (Utah's my529, Nevada's Vanguard plan) to over 1.0% (some advisor-sold plans). Low fees compound into thousands more for your child.
- Use an age-based portfolio. These automatically shift from aggressive (stocks) when your child is young to conservative (bonds/cash) as college approaches. It's the simplest and most effective approach for most families.

The New Roth IRA Rollover Rule
Starting in 2024, unused 529 funds can be rolled into a Roth IRA for the beneficiary under these conditions: the 529 account must have been open for at least 15 years, the rollover is subject to annual Roth IRA contribution limits ($7,000 in 2026), and there is a $35,000 lifetime cap.
This removes the biggest fear about 529 plans — that unused money gets hit with a 10% penalty. Now, overfunding a 529 simply gives your child a head start on retirement savings. It also makes 529 plans attractive for families who might receive scholarships or financial aid.

Frequently Asked Questions
What if my child gets a scholarship and doesn't need the 529 money?
You have several options: (1) Roll up to $35,000 into a Roth IRA for the beneficiary (new rule, after 15 years). (2) Change the beneficiary to a sibling, cousin, parent, or other family member. (3) Withdraw up to the scholarship amount penalty-free (you'll owe income tax on earnings but no 10% penalty). (4) Save it for graduate school, which is also a qualified expense.
How much should I save for college each month?
A common target is one-third of projected costs from savings, one-third from income during college, and one-third from aid/scholarships. For a newborn targeting an in-state public school ($270,000 projected total), the savings third is ~$90,000. At 7% return, that requires approximately $250/month starting at birth. Use our College Savings Calculator for an exact number based on your situation.
Do 529 plans affect financial aid?
Parent-owned 529 plans are counted as parent assets on the FAFSA, assessed at a maximum rate of 5.64% — far less impactful than student-owned assets (20%). Grandparent-owned 529 plans are no longer reported as student income on the FAFSA (starting 2024-25), making them even more favorable. A $50,000 parent-owned 529 reduces aid eligibility by only ~$2,820.
Can I use a 529 plan for graduate school or trade school?
Yes. 529 funds can be used at any accredited post-secondary institution, including graduate programs, law school, medical school, MBA programs, trade schools, and community colleges. The school must be eligible for federal financial aid (Title IV). This includes most accredited institutions in the U.S. and many abroad.
