529 Plans Explained: How to Start Saving for College
·
May 2, 2026
The average cost of a four-year public university education is currently over $100,000 — and it continues to rise faster than inflation. Starting to save when your child is a newborn gives you the single most powerful advantage in college funding: time. Even modest monthly contributions grow significantly over 18 years thanks to compound returns.
This guide demystifies 529 plans, explains your options, and helps you start a savings strategy that fits your budget — whether that's $25 a month or $500.
Investing $100/month from birth with a 7% average annual return grows to approximately $43,000 by age 18. The same $100/month starting at age 10 grows to only about $15,000. Time is your most powerful tool.
Why 529 Plans Are the Best College Savings Tool
529 plans are state-sponsored investment accounts specifically designed for education expenses. They offer three major tax advantages: contributions grow tax-free, withdrawals for qualified education expenses are tax-free at the federal level, and many states offer income tax deductions or credits for contributions. No other savings vehicle offers this combination of benefits for education.
As of 2024, the SEC notes that 529 plans can now be used for more than just college. Qualified expenses include K-12 tuition (up to $10,000/year), apprenticeship programs, and student loan repayment (up to $10,000 lifetime). Recent legislation also allows unused 529 funds to be rolled into a Roth IRA for the beneficiary (subject to conditions), reducing the risk of "oversaving."
How 529 Plans Work
You open an account, name a beneficiary (your child), and choose investment options (typically age-based portfolios that automatically become more conservative as the child approaches college age). Anyone can contribute — parents, grandparents, aunts, uncles, friends. Contributions are made with after-tax dollars (no federal deduction), but the growth and withdrawals are tax-free for qualified expenses.
Qualified expenses include: tuition and fees, room and board (up to the school's cost of attendance for off-campus housing), books and supplies, computers and internet access, and special needs equipment.
Choosing a 529 Plan
You can use any state's 529 plan regardless of where you live or where your child goes to school. However, your state's plan may offer tax benefits (like a state income tax deduction) that make it more advantageous. Check whether your state offers a tax deduction first. If your state has no income tax or no 529 tax benefit, compare plans based on fees, investment options, and performance.
Key factors to compare: expense ratios (look for under 0.5%), investment options (age-based portfolios are simplest), minimum contribution requirements, and state tax benefits.
How Much to Save
The "right" amount depends on your goals and budget. A common target is to save enough to cover about 1/3 of projected college costs, with the remaining 2/3 coming from current income, financial aid, scholarships, and student contributions. For a public university, that means saving roughly $50,000–$75,000 by age 18.
Monthly savings needed to reach $50,000 by age 18 (assuming 7% annual return): Starting at birth: ~$130/month. Starting at age 5: ~$200/month. Starting at age 10: ~$360/month. Even if you can't hit these targets, any amount helps. $25/month from birth grows to approximately $10,800 — that's a full year of community college tuition.
Alternatives to 529 Plans
Coverdell ESA: Similar tax benefits to 529 plans but with a $2,000 annual contribution limit and income restrictions. Less useful for most families due to the low cap, but covers a broader range of K-12 expenses.
Custodial accounts (UGMA/UTMA): Investment accounts in your child's name. No tax-free growth for education specifically, and the funds become the child's property at age 18 or 21 (state-dependent). They count more heavily against financial aid eligibility.
Roth IRA: Contributions can be withdrawn penalty-free for education. However, this reduces your retirement savings. Most financial advisors recommend maximizing 529 and retirement accounts before using a Roth for education.
I Bonds: Government savings bonds with tax-free interest when used for education (income limits apply). Very safe, modest returns, limited to $10,000/year in purchases per person.
Frequently Asked Questions
What happens if my child doesn't go to college?
You have several options: change the beneficiary to another family member (sibling, cousin, niece/nephew, or even yourself), use the funds for other qualified education (trade school, apprenticeship, K-12), roll up to $35,000 into a Roth IRA for the beneficiary (new as of SECURE 2.0 Act, subject to conditions), or withdraw with a 10% penalty on earnings only (contributions are never penalized).
Does a 529 plan affect financial aid?
Parent-owned 529 plans are treated as parental assets on the FAFSA, which has a minimal impact on aid eligibility (assessed at a maximum of 5.64% of the account value). This is much more favorable than student-owned assets (assessed at 20%). Grandparent-owned 529s are no longer counted on the simplified FAFSA starting 2024-25.
Can grandparents contribute to a 529 plan?
Yes, and it's one of the best gifts they can give. Grandparents can contribute to a parent-owned 529 or open their own. Contributions up to $18,000 per year (2024) per grandparent qualify for the annual gift tax exclusion. There's also a special 5-year election allowing a lump sum of up to $90,000 without gift tax consequences.
Should I save for college or pay off my student loans first?
Focus on high-interest student loans first. If your student loan interest rate is higher than expected 529 investment returns (roughly 7%), paying down the loan gives a guaranteed better return. For lower-interest federal loans, contributing to a 529 while making minimum loan payments may be the better math. Always prioritize retirement savings and emergency funds over both.
What if I can only save $25 a month?
Start. $25/month from birth, invested in an age-based 529 portfolio, grows to approximately $10,800 by age 18. That covers books and supplies for four years, or a year of community college. You can always increase contributions later as your income grows. The habit of saving matters more than the amount.
