There are a lot of ways to save for college. Most of them are fine. One of them is significantly better: the 529 plan. It's the only savings account where you get tax-free growth specifically for education expenses, and most people either don't know it exists or think it's more complicated than it is.
It's not complicated. Here's everything you need to know.
What Is a 529 Plan?
A 529 is a state-sponsored investment account designed specifically for education savings. You contribute after-tax money, it grows tax-free, and withdrawals are tax-free as long as you use the money for qualified education expenses.
Qualified expenses include: tuition, fees, books, supplies, room and board, computers used for school, and even K-12 tuition (up to $10,000/year). As of 2024, you can also roll unused funds into a Roth IRA for the beneficiary (up to $35,000 lifetime), which removes the biggest objection people had to opening one.
How the Tax Advantage Actually Works
Let's say you invest $10,000 in a 529 today. Over 18 years, assuming 7% average annual growth, it grows to roughly $34,000. In a regular taxable account, you'd owe capital gains tax on that $24,000 in growth. In a 529, you owe nothing — as long as you spend it on education.
Some states sweeten the deal further with a state income tax deduction on contributions. If your state offers it, you might get an immediate 5–10% return just for putting money in.
Which 529 Plan Should You Use?
Every state has its own plan, but you're not limited to your home state's plan. You can use any state's 529 for any school in any state (or abroad).
If your state offers a tax deduction on contributions, start there. That's usually the right call. If your state doesn't offer a deduction, use one of the nationally recognized plans with low fees:
- Utah (my529) – consistently top-rated, Vanguard funds, very low fees
- Nevada (Vanguard 529) – Vanguard funds, simple, low cost
- New York (NY 529 Direct Plan) – Vanguard funds, good options
Look for plans with expense ratios under 0.15%. Fees compound against you just like returns compound for you.
How Much Should You Save?
A useful target: aim to cover 50% of projected college costs. Financial aid, scholarships, and the student's contribution cover the rest.
Current average cost of four-year public university (in-state): around $110,000 total for tuition, room, and board. Private: $240,000+. With 18 years of growth, here's what monthly contributions produce at 7% average returns:
| Monthly Contribution | Balance at 18 Years |
|---|---|
| $100 | ~$43,000 |
| $200 | ~$86,000 |
| $300 | ~$129,000 |
| $500 | ~$215,000 |
Start what you can. Even $50 a month opened at birth makes a meaningful dent by 18.
What If My Kid Doesn't Go to College?
This is the question that stops people from opening a 529. The answer is: it's fine.
- Change the beneficiary to another family member (sibling, cousin, even yourself) with no penalty
- Roll it to a Roth IRA for the beneficiary (up to $35,000 lifetime, subject to rules)
- Use it for trade school or vocational programs — many qualify
- Non-qualified withdrawal: you pay income tax + 10% penalty on earnings only, not contributions. Still not catastrophic.
The risk of not using a 529 is worse than the risk of opening one.
How to Open One
- Check your state's plan for a tax deduction at savingforcollege.com
- If no deduction, open with Utah my529 or Vanguard 529
- Pick an age-based allocation (it automatically shifts to bonds as college nears)
- Set up automatic monthly contributions — even $100 to start
- Tell grandparents the account info. Birthday and holiday contributions add up fast.
Open it before the end of the year if you want a state tax deduction. Most plans take under 20 minutes to open online.
The Bottom Line
Tax-free growth specifically for college expenses. State tax deductions in many cases. Flexible if plans change. Low-cost index fund options. The 529 is the obvious choice for college savings — the only question is whether you open one today or six months from now. One of those answers costs you money.
