Understanding College Costs

Before choosing a savings vehicle, understand what you’re saving for:

Average College Costs (2025-2026)

Type In-State Public Out-of-State Public Private
Tuition $11,440 $30,500 $43,350
Room & Board $12,710 $12,710 $15,370
Books & Supplies $1,250 $1,250 $1,250
Transportation $1,230 $1,230 $1,230
Personal $2,120 $2,120 $2,120
Total $28,750 $47,810 $63,320

For a four-year degree, total costs range from $115,000 to $250,000+.

Factors Affecting Costs

  • Public vs. private institution
  • In-state vs. out-of-state residency
  • Room and board choices
  • Financial aid eligibility
  • Duration of study
  • Graduate school plans

529 Plans: The Education Savings Account

529 plans are tax-advantaged accounts specifically designed for education savings.

How 529 Plans Work

  • Open an account in your state (or any state)
  • Designate a beneficiary (the student)
  • Contribute after-tax dollars
  • Money grows tax-free
  • Withdrawals tax-free for qualified education expenses

Types of 529 Plans

Prepaid Tuition Plans: Lock in current tuition rates at participating schools. Protects against tuition increases. Limited to public schools in the state (typically).

College Savings Plans: Invest in mutual fund-like options. Money can be used at any accredited school. More flexible but market risk exists.

529 Plan Benefits

Tax Advantages: Earnings grow federal tax-free. Qualified withdrawals are tax-free. Some states offer state income tax deductions.

High Contribution Limits: Most states allow $300,000+. Significantly higher than custodial accounts.

No Income Limits: Anyone can contribute regardless of income.

Flexibility: Can change beneficiaries to another family member if needed.

Financial Aid Impact: Treated as parental asset (less impact on financial aid) until beneficiary is of college age.

529 Plan Disadvantages

Limited Investment Options: Limited to plan’s investment menu.

Penalties for Non-Education Withdrawals: Earnings subject to 10% penalty plus income tax.

Residency Requirements: Some states require residency for tax benefits.

Gifting Limits: Annual contributions over $18,000 (2026) may require gift tax reporting.

State-Specific Considerations

Most states offer their own 529 plans with different:

  • Investment options
  • Fees and expenses
  • Tax benefits
  • Residency requirements

You can invest in any state’s 529 plan. Often, your state’s plan offers the best tax benefit, but not always. Compare options.

Custodial Accounts (UGMA/UTMA)

Uniform Gifts to Minors Act (UGMA) and Uniform Transfers to Minors Act (UTMA) accounts allow adults to hold assets for minors.

How Custodial Accounts Work

  • Open an account as custodian
  • Transfer assets to the account
  • Child gains control at age of majority (18-21, depending on state)
  • No restrictions on use of funds

Custodial Account Benefits

Flexibility: Can use funds for anything benefiting the child—not just education.

Investment Freedom: Invest in anything—stocks, bonds, real estate, mutual funds.

Simpler Rules: No specific beneficiary requirements.

No Contribution Limits: (practically speaking)

Financial Aid: First $2,500/year is counted as student income (neutral); above that, 50% counts against aid.

Custodial Account Disadvantages

Tax Implications: First $1,300 (2026) tax-free; next $1,300 at child’s rate; earnings above that taxed at trust rates.

Irrevocable: Once contributed, can’t be taken back.

No Income Limits: Unlike some accounts, there are no income limits.

Control Transferred: Child gains full control at age of majority. Can use money for anything.

Financial Aid Impact: More heavily counted than 529 plans.

Roth IRAs for Education

While not designed for education, Roth IRAs can serve this purpose.

How Roth IRAs Work

  • Retirement account with after-tax contributions
  • Money grows tax-free
  • Qualified withdrawals are tax-free
  • Can withdraw contributions (not earnings) anytime

Using Roth IRA for Education

You can withdraw earnings tax-free for:

  • Qualified education expenses
  • First home purchase ($10,000 lifetime limit)
  • Certain hardships

Roth IRA Benefits

Flexibility: Can use for education, retirement, or other purposes.

Tax-Free Growth: If used for education, completely tax-free.

No Mandatory Withdrawals: Unlike 529 plans or traditional IRAs.

Can Keep Contributing While Working: Even after age 72 (unlike traditional IRA).

Roth IRA Disadvantages

Income Limits: Modified AGI limits restrict contributions. Phase-out begins at $146,000 single, $230,000 married.

Contribution Limits: $7,000/year (2026), much lower than 529 plans.

Education Penalty: Earnings used for non-education withdrawals before 59½ incur 10% penalty plus taxes.

Retirement Priority: Using retirement funds for education compromises retirement savings.

Which Account Is Best?

Choose 529 if:

  • You know funds will be used for education
  • You want tax benefits
  • You want professional management
  • You want to limit child’s control

Choose Custodial Account if:

  • Education is uncertain
  • You want maximum flexibility
  • You want to involve child in investing
  • You plan to use funds for non-education purposes

Choose Roth IRA if:

  • You have retirement needs too
  • Income is within limits
  • You want maximum flexibility
  • You might not use all funds for education

Financial Aid Considerations

How you save affects financial aid eligibility:

Expected Family Contribution (EFC)

The federal formula calculates expected family contribution based on:

  • Parent income and assets
  • Student income and assets
  • Household size
  • Number in college

Impact of Savings Vehicles

529 Plans (Parent-Owned): Asset is parental asset. Only 5.64% of assets count against aid.

529 Plans (Grandparent-Owned): Not counted as parent asset but counts as student asset once withdrawn.

Custodial Accounts: First $2,500/year is neutral; above that, 50% counts as student income.

Roth IRAs: Not counted as asset (retirement account). Withdrawals count as student income.

Strategies

  • Grandparent-owned 529s avoid initial impact but count after withdrawal
  • Parent-owned 529s have moderate impact
  • Keep assets in parent name, not child’s
  • Withdraw 529 funds in base year to minimize reporting

Strategy by Age

Before Birth

  • Open 529 plan
  • Start with small contributions
  • Invest aggressively (more stocks)

Elementary/Middle School

  • Continue contributions
  • Maintain aggressive investment
  • Consider adding custodial account if education uncertain

High School

  • Reduce stock allocation gradually
  • Maximize 529 contributions
  • Apply for scholarships
  • Complete FAFSA strategically

During College

  • Withdraw funds each semester
  • Keep records of expenses
  • Consider splitting costs between accounts

Contribution Strategies

Getting Started

  • Start early—even small amounts compound
  • Set up automatic contributions
  • Increase contributions with income growth
  • Take advantage of gift occasions

Maximizing Benefits

  • Check employer retirement before 529
  • Don’t sacrifice retirement for college savings
  • Consider tax benefits of your state’s plan
  • Use windfalls strategically (tax refunds, bonuses)

Common Mistakes

  • Saving too much in child’s name
  • Ignoring financial aid implications
  • Using retirement funds
  • Not starting because amount seems small

Conclusion

Saving for college requires thoughtful planning. The best approach depends on your:

  • Income and tax situation
  • Confidence education will be used
  • Desire for control vs. restrictions
  • Financial aid expectations
  • Other financial goals

For most families, a 529 plan offers the best combination of tax benefits, contribution limits, and flexibility for education expenses. But your specific situation may warrant different choices—or a combination.

Start saving early, maximize advantages, and adjust your strategy as circumstances change. Your child’s future self will thank you.
