College Savings and Investing in Your 40s
Last updated: March 2026
In your 40s, college expenses are approaching fast while retirement savings still need decades of growth. This is the most common investment conflict for parents in their peak earning years. This guide helps you navigate the tension between funding education and securing your own future, with specific ETF strategies for both goals.

The Retirement vs. College Priority Framework
The cardinal rule of financial planning is that you can borrow for education but you cannot borrow for retirement. Prioritize your retirement contributions before college savings in every scenario. If you can only fund one goal fully, choose retirement. Your children have their entire working lives ahead of them, access to scholarships, and the ability to attend affordable institutions.
This does not mean ignoring college savings. It means establishing a clear hierarchy: employer 401(k) match first, then emergency fund, then IRA, then 529 plan, then additional 401(k), then taxable investing. Only after your retirement contributions are solid should you increase 529 contributions.
529 Plan Strategy When College Is 5 to 10 Years Away
With college five to ten years away, your 529 plan should begin shifting from aggressive to moderate. At the ten-year mark, a 60/40 stock-to-bond allocation protects against a major crash while still providing growth. By five years before enrollment, shift to 40/60 or even 30/70 stocks to bonds.
If you are behind on college savings, resist the urge to keep an aggressive allocation hoping for higher returns. A stock market crash when your child is 15 could cut your college fund by 30 to 40 percent with no time to recover. Better to accept moderate returns and sleep well than to gamble on needing a strong market at exactly the wrong time.
How Much College Savings Is Enough
The average annual cost of a public four-year university is approximately $23,000 for in-state students and $41,000 for out-of-state, including room and board. Private universities average $54,000 or more. Over four years, you are looking at $92,000 to $216,000 per child.
A realistic goal for most families is to cover 50 to 75 percent of public university costs through savings, with the remainder funded through scholarships, current income during college years, and modest student loans. For a target of $70,000 per child, contributing $300 per month for 15 years at 7 percent growth gets you there.
Financial Aid Considerations for Investors
Your investment account balances affect financial aid eligibility. Assets in parent-owned 529 plans are assessed at a maximum rate of 5.64 percent of their value in the financial aid formula, making them one of the most aid-friendly savings vehicles. Retirement accounts like 401(k)s and IRAs are not counted at all.
This has portfolio implications. Money in a taxable brokerage account is assessed at the same 5.64 percent rate as 529s, but money in your child's name such as a custodial account is assessed at 20 percent. If financial aid is part of your plan, keep education savings in parent-owned 529 plans and maximize retirement accounts that are excluded from financial aid calculations.
Alternative College Funding Strategies
Beyond 529 plans, several strategies can reduce the college funding burden. Roth IRA contributions can be withdrawn tax and penalty-free for any reason, and earnings can be used for qualified education expenses without the 10 percent penalty (though income tax still applies on earnings). This makes the Roth IRA a flexible dual-purpose vehicle for retirement and education.
Consider whether your child can earn merit scholarships through academic or athletic achievement. Many families also benefit from their child attending community college for two years before transferring to a four-year university, cutting total costs by 30 to 40 percent. The key is having a comprehensive plan rather than relying solely on savings to cover the full cost.

Action Steps
Confirm retirement is fully funded first
Ensure you are contributing at least 15% of income to retirement before increasing 529 contributions.
Calculate your college savings gap
Determine the total cost you plan to cover per child. Subtract current 529 balance and project whether current contributions will close the gap.
Shift 529 to age-appropriate allocation
If college is 5-10 years away, move to 60/40 stocks-to-bonds. Under 5 years, shift to 40/60 or more conservative.
Understand financial aid implications
Review how your savings and investment accounts affect aid eligibility. Maximize retirement accounts which are excluded from aid calculations.
Explore alternative funding sources
Research merit scholarships, community college transfer paths, and Roth IRA flexibility as supplements to 529 savings.
Frequently Asked Questions
Should I stop retirement savings to fund college?
Never. Retirement contributions should always come first. You can borrow for college but not for retirement. Maintain at least your employer 401(k) match and IRA contributions regardless of college expenses.
How conservative should my 529 be with 5 years to college?
With 5 years until enrollment, shift to a 40/60 or 30/70 stock-to-bond allocation. A market crash at this point would leave no time to recover, and protecting capital becomes more important than growth.
Does my 529 affect financial aid?
Parent-owned 529 plans are assessed at a maximum of 5.64% of their value in the financial aid formula. This is much more favorable than custodial accounts at 20%. Retirement accounts are excluded entirely.
Can I use my Roth IRA for college costs?
Roth IRA contributions can be withdrawn anytime tax and penalty-free. Earnings used for qualified education expenses avoid the 10% penalty but are still subject to income tax. This makes the Roth a flexible dual-purpose vehicle.
