How Much Does College Actually Cost?
College costs have outpaced inflation for decades. According to the College Board's Trends in College Pricing 2025 report, average annual cost of attendance (tuition, fees, room, and board) breaks down as follows:
| Institution Type | Annual Cost (2025–26) | 4-Year Total |
|---|---|---|
| In-state public university | $24,030 | $96,120 |
| Out-of-state public university | $43,280 | $173,120 |
| Private nonprofit university | $56,190 | $224,760 |
College costs have risen at an average rate of 3.1% per yearover the past decade (Education Data Initiative, 2025). A child born today could face costs 50–60% higher than current figures by the time they enroll at age 18.
529 Plans: The Most Tax-Efficient Way to Save
A 529 plan is a state-sponsored, tax-advantaged investment account specifically designed for education savings. Every state plus the District of Columbia offers at least one plan.
Key 529 Benefits
- Tax-free growth: Investment earnings are never taxed as long as withdrawals go toward qualified education expenses.
- Tax-free withdrawals: Tuition, room and board, books, computers, and up to $10,000/year for K–12 tuition all qualify.
- State tax deductions: Over 30 states offer a state income tax deduction or credit for 529 contributions. The average deduction cap is around $5,000–$10,000 per year (Tax Foundation, 2025).
- High contribution limits: Most state plans allow total balances of $300,000 to $550,000 per beneficiary.
- Roth IRA rollover: Under SECURE 2.0, unused funds can roll into a Roth IRA for the beneficiary (up to $35,000 lifetime, account must be open 15+ years).
529 Plan Types
| Feature | Education Savings Plan | Prepaid Tuition Plan |
|---|---|---|
| What it covers | Any qualified expense | Tuition and fees only |
| Investment options | Mutual funds, target-date funds | Locks in current tuition rates |
| School restrictions | Any eligible institution | Usually limited to in-state public schools |
| Risk | Market-dependent returns | Low (state-backed guarantees) |
| Availability | All 50 states + DC | About 10 states |
Education savings plans are far more popular and flexible. Morningstar's 2025 529 report found that over 92% of 529 assets are held in education savings plans rather than prepaid plans.
How Much Should You Save Each Month?
The right monthly savings target depends on your child's age, the type of school you're targeting, and what percentage of costs you want to cover. Here are benchmarks assuming a 6% annual return and 3% annual cost inflation:
| Child's Age | Monthly to Cover 50% Public | Monthly to Cover 75% Public | Monthly to Cover 100% Public |
|---|---|---|---|
| Newborn | $230 | $350 | $465 |
| Age 5 | $340 | $510 | $680 |
| Age 10 | $580 | $870 | $1,160 |
| Age 15 | $1,450 | $2,175 | $2,900 |
The gap between starting at birth versus age 10 is stark. A newborn's parents need $465/month for full coverage. Parents who wait until age 10 need $1,160/month— nearly 2.5 times more — because there's less time for compound growth.
529 Plans and Financial Aid
One of the most common concerns about 529 plans is whether they hurt financial aid eligibility. The short answer: the impact is minimal.
FAFSA Treatment of 529 Assets
- Parent-owned 529: Counted as a parental asset. Only 5.64% of the value is factored into the Expected Family Contribution (EFC) each year.
- Student-owned 529: Counted as a student asset at 20% — a much bigger hit. Avoid this structure.
- Grandparent-owned 529: As of the 2024–2025 FAFSA cycle, distributions from grandparent-owned 529 plans no longer count as untaxed student income. This was a major improvement.
According to Savingforcollege.com, a parent-owned 529 with a $50,000 balance reduces need-based aid eligibility by a maximum of $2,820 per year. The tax-free growth alone typically outweighs this small aid reduction.
Alternatives to 529 Plans
Coverdell Education Savings Accounts (ESAs)
ESAs offer tax-free growth like 529 plans but cap annual contributions at $2,000 per beneficiary and phase out for higher earners (MAGI above $110,000 single / $220,000 married). Funds must be used by age 30. The low contribution limit makes ESAs supplementary at best.
Custodial Accounts (UTMA/UGMA)
These are taxable brokerage accounts in the child's name. No contribution limits and no restrictions on use, but investment gains are taxable and the account counts as a student asset on the FAFSA (20% assessment rate). The child gains full control at age 18 or 21 depending on the state.
Roth IRA
Parents can withdraw Roth IRA contributions (not earnings) penalty-free at any time. Earnings can be withdrawn penalty-free for qualified education expenses, though income tax still applies on the earnings portion. The downside: every dollar used for college is a dollar not compounding for retirement.
College Savings Strategies
Start with Any Amount
Fidelity's 2025 College Savings Report found that families who started saving any amount before their child's first birthday had an average 529 balance of $44,587 by age 18, compared to $18,240 for families who started at age 5. Even $100/month from birth adds up.
Use Age-Based Portfolios
Most 529 plans offer age-based investment options that automatically shift from aggressive (stocks) to conservative (bonds) as your child approaches college age. Vanguard data shows these target-date-style portfolios have returned an average of 6.2% annually over the past 15 years.
Automate Contributions
Set up automatic monthly transfers. Behavioral finance research consistently shows that automated savings plans lead to 3–4 times highertotal savings compared to manual, ad-hoc contributions (Thaler & Benartzi, “Save More Tomorrow” study).

How much should I save per month for college?
For a newborn targeting a four-year public university, saving approximately $350 to $450 per month in a 529 plan earning 6% annually should cover roughly 75% of projected costs. Starting when a child is 5 requires about $650 to $800 per month to reach the same goal. The earlier you start, the more compound growth does the work.
What is a 529 plan and how does it work?
A 529 plan is a tax-advantaged savings account designed for education expenses. Contributions grow tax-free, and withdrawals are tax-free when used for qualified education expenses including tuition, room and board, books, and up to $10,000 per year for K–12 tuition. Each state sponsors its own 529 plan, and you can invest in any state's plan regardless of where you live.
Does a 529 plan affect financial aid?
A parent-owned 529 plan is treated as a parental asset on the FAFSA, which means only up to 5.64% of its value is counted in the Expected Family Contribution. A $50,000 balance would reduce aid by a maximum of $2,820. Distributions from parent-owned 529 plans are not counted as student income. Grandparent-owned 529 plans no longer affect FAFSA as of the 2024–2025 cycle.
What happens to unused 529 funds?
Starting in 2024 under the SECURE 2.0 Act, unused 529 funds can be rolled over into a Roth IRA for the beneficiary, up to a lifetime limit of $35,000. The 529 account must have been open for at least 15 years. You can also change the beneficiary to another family member, use funds for graduate school, or withdraw with a 10% penalty plus income tax on earnings.
How much does college cost in 2026?
According to the College Board Trends in College Pricing 2025 report, the average annual cost of attendance (tuition, fees, room, and board) is approximately $24,030 for in-state public universities and $56,190 for private nonprofit universities. Over four years, that totals roughly $96,120 for public and $224,760 for private institutions before financial aid.
