A quick note before we start: I’m not a financial advisor, an accountant, or an investment professional. I’m a grandmother who’s spent time researching this because I wanted to do something for my own granddaughters. Everything below is general information, not personal advice. Anything involving real money for a child’s future is worth a conversation with an actual financial advisor or tax professional. Have that conversation before you commit to anything. Invest at your own risk.
With that said, here’s what I’ve learned about saving for grandchild college. Below are the main ways grandparents put money aside, and what’s actually worth considering about each one.
529 college savings plans
A 529 plan is a tax-advantaged account states build specifically for education expenses. That includes tuition, room and board, books, and in many states even K-12 private school tuition. The money grows tax-free, and withdrawals are tax-free too, as long as you spend them on qualifying education costs.
The reason 529s come up so often for grandparents specifically is something called the “grandparent loophole.” As of the 2026–27 financial aid cycle, money in a grandparent-owned 529 no longer counts as student income on the FAFSA. The same goes for cash gifts from a grandparent. That used to hurt financial aid eligibility; now it doesn’t. You can currently give up to $19,000 a year per grandchild without triggering gift tax. That doubles to $38,000 if you’re contributing jointly with a spouse. That leaves real room to help without any tax complications.
Things to consider: 529 plans are state-run programs. No company sells them, so there’s no “sign up here for a bonus” link I can point you to. You open one directly through your state’s plan, or another state’s, since you’re not required to use your own. Some private colleges use a separate financial aid form called the CSS Profile, which can still count grandparent contributions differently. So if your grandchild is likely to apply somewhere elite and private, that’s worth knowing ahead of time. And the money really has to go toward education. If you don’t use it that way, you’ll owe taxes and a penalty on the earnings portion.
Custodial accounts (UGMA/UTMA)
A custodial account is a regular investment account you open in a child’s name. An adult manages it, usually a parent, though grandparents can often serve as custodian too. That lasts until the child reaches adulthood, typically 18 to 25 depending on the state. A 529 exists specifically for education savings. A custodial account isn’t restricted that way — you can eventually use the money for anything.
A couple of apps have built specifically around this idea for kids and gifting-minded relatives. Acorns Early is Acorns’ custodial investing product. It targets exactly the “grandparent wants to invest for a grandchild” use case. EarlyBird is a similar gifted-investing app where family and friends contribute together to a child’s account. It also offers a modest referral bonus for both sides when you invite someone.
Things to consider: The account is legally the child’s. The money becomes theirs once they hit the age of majority in your state. That means there’s no changing your mind later. If they want to spend it on something other than what you had in mind, that’s their call. It also counts as the student’s own asset on financial aid forms, not the grandparent’s. That can affect aid eligibility more than a 529 would. And since it’s a real brokerage account, it carries real investment risk. The value can go down as well as up.
Gifting actual stock
If you’d rather give something more direct than a savings account, gifting shares of an individual stock is another route grandparents take. You can buy a share outright and transfer it to a custodial account yourself. Or use an app like Robinhood instead — it has a referral program that gives both people a free stock when someone signs up through an invite.
Things to consider: A single share of stock is a nice gesture. It’s also a good way to introduce an older grandkid to how investing works. But it’s not really a savings strategy on its own. The value of one share can swing quite a bit. And it doesn’t diversify risk the way a fund or a 529 portfolio does. I’d think of this as more of a teaching moment than a college fund.
A word on crypto
Cryptocurrency comes up in this conversation because platforms like Coinbase do have real affiliate and referral programs. I want to be straightforward about that rather than pretend it doesn’t exist as an option. But I’ll say this clearly. Most financial writers and financial advisors caution against using crypto for a near-term, fixed goal like college savings. I’d echo that caution rather than talk anyone into it. Crypto can lose a large percentage of its value quickly. There’s no guarantee it recovers on the timeline a grandchild needs it. Maybe you’re already comfortable with crypto as part of your own investing. If so, you might want to set some aside with a grandchild in mind. That’s a personal call between you and your own judgment, and ideally a financial advisor. But I wouldn’t recommend it as a first or only option for money you’re counting on being there for tuition.
So which one is “best”?
Honestly, it depends on what you’re trying to do. Saving for grandchild college specifically points you toward a 529, while more flexible goals point elsewhere:
For money that’s specifically for education, a 529 plan is the most tax-efficient option. And the recent FAFSA changes make it more attractive for grandparents than it used to be.
With more flexibility in mind — money that could go toward a car, a first apartment, or anything else once they’re grown — a custodial account fits better. The tradeoff is that it becomes fully theirs at a set age, regardless of what you’d hoped for.
When you’re mainly looking for a meaningful, teachable gift rather than a savings vehicle, a single gifted stock can be a nice starting point for an older grandkid. Pair it with a conversation about how investing actually works.
If crypto is already part of your own portfolio and you understand the risk, it’s an option that exists. Just not one I’d lean on for money with a deadline attached.

The bottom line
None of this replaces sitting down with a real financial advisor, especially once real money is involved. Tax rules change, and state 529 plans differ from each other. Everyone’s situation with family, taxes, and financial aid looks a little different too. What I can tell you is this: saving for grandchild college now, in whatever small way you’re able to, is worth more down the road. Most of us don’t realize that at the time.

Again — I’m not a financial professional, and this isn’t personalized financial advice. Please talk to a qualified advisor before making any investment decisions for a child’s future.
