Creative Ways to Fund a Savings Account for Your Grandchild
You don't need a windfall to build your grandchild's financial future. With a little creativity and consistency, most grandparents can find money they didn't know they had and put it to work for the people they love most.
One of the most meaningful things you can do for your grandchild is start saving for their future—and you don't need to be wealthy to do it. Even small, consistent contributions can grow into something significant over time. The challenge for many grandparents isn't motivation. It's finding the money.
The good news: it's often already there. You just have to know where to look.
What's the easiest way for grandparents to start saving for a grandchild?
Start small and start now. That's the most important advice anyone can give you, and the numbers back it up.
What Small Contributions Can Grow To
At a 6% average annual return, here's what consistent monthly contributions look like by the time your grandchild turns 18:
- $10/month → $3,874
- $20/month → $7,747
- $50/month → $19,368
- $100/month → $38,735
- $200/month → $77,471
These figures assume consistent monthly contributions and a 6% average annual return, compounded monthly.
Your actual returns will vary. Use a compound interest calculator to run your own numbers.
The point isn't the exact figure: it's the principle. Time is the most powerful tool available to you, and the earlier you start, the more time you have. Twenty dollars a month when your grandchild is born becomes nearly $7,800 by the time they head off to college or start their adult life. That's a semester of living expenses, a security deposit, or a start on their own savings habit.
For guidance on where to put the money once you have it, see our Grandparent's Guide to Saving and Investing for Grandkids. But for now, let’s talk about where to find that money.
How can grandparents redirect money they're already spending?
The most reliable source of savings is spending you're already doing—just redirected.
Think about what you typically spend on your grandchild over the course of a year: birthday gifts, holiday gifts, small treats and toys picked up on impulse. For many grandparents, that adds up to several hundred dollars annually, sometimes more. What if even a portion of that went into a savings account instead?
This doesn't mean stopping gift-giving. It means being intentional about the balance. A smaller gift at the holidays paired with a contribution to their savings account is a gift that serves them twice: once now, once later. Many grandparents find that as their grandchildren get older, the children themselves begin to understand and appreciate the savings contribution more than another toy.
You can also look at your own regular spending with fresh eyes. A subscription you rarely use. A gym membership that's gathering dust. Dining out one fewer time a month. These aren't dramatic sacrifices—they're small adjustments that, redirected consistently, add up to real money over 18 years.
How does redirecting gift money into savings add up over time?
Consider the birthday and holiday gifts from grandparents across a typical year. If you spend $200 a year on gifts and redirect half ($100) into a savings account, that's just over $8 a month. At 6% over 18 years, $8 a month becomes roughly $3,100.
One thing worth mentioning before you open an account: let the parents know what you're planning. They may already have a Trump account, a 529 plan, or a savings account set up for their child and would prefer you contribute to that rather than open a separate one. And if you do open your own account, make sure they're on board before putting it in your grandchild's name. A quick conversation early saves confusion and potential complications later.
What small daily habits can fund a grandchild's savings account?
Some of the most effective savings strategies are the least glamorous ones.
Rounding up your purchases is one of them. Several banking apps now offer automatic round-ups: every time you spend $4.60, the extra $0.40 goes into a savings account. It sounds trivial, but regular spending rounded up consistently can generate $20–$40 a month without any conscious effort.
Setting a standing monthly transfer—even $10 or $20—on the same day every month removes the decision from the equation entirely. You won't miss what you never see in your checking account, and your grandchild's account grows whether you think about it or not.
If you have a tendency to buy small gifts and treats often, here’s a proven trick. Instead of spending $10.99 on a Paw Patrol water bottle that caught your eye, transfer $10.99 to savings. Done regularly, your generous impulses can become a nest egg for your grandchild instead of a collection of things they quickly outgrow.
Don’t discount the power of your spare change. A change jar on the kitchen counter, emptied into a savings deposit once a month, can add up over time. It's how many grandparents quietly, consistently build a fund that will matter to their grandchild someday.
How can grandparents on a fixed income still contribute?
The answer is the same as for anyone: start with whatever you can, and be consistent. Ten dollars a month for 18 years at 6% becomes nearly $3,900. Five dollars a month becomes just under $2,000. Neither of those figures is insignificant to a young adult starting out.
The other option for grandparents with limited monthly cash flow is to contribute when you can rather than on a fixed schedule. Think tax refunds, a small inheritance, the occasional windfall. Lump sum contributions early in a child's life have a long time to grow. A single $500 contribution at birth grows to over $1,400 by age 18 at a 6% annual return.
The goal is to create a meaningful fund for their future. Meaningful doesn’t have to mean a fortune.
What should grandparents do once they've found the money?
Once you’ve found the money, put it somewhere it can grow. A standard savings account is a safe place to start, but the interest rates are low and the long-term growth is limited. Most grandparents saving for a grandchild's future will do better with a 529 college savings plan, a custodial account, or U.S. savings bonds, each of which has different tax advantages and flexibility.
For a full breakdown of the options, read our Grandparent's Guide to Saving and Investing for Grandkids. It covers every major account type, the pros and cons of each, and where to open them.
The most important step is simply the first one: decide on an amount, set up the account, and start. Your grandchild has 18 years on their side. So do you.

Frequently Asked Questions
How much should grandparents save for a grandchild each month? There's no right answer—any amount saved consistently is better than none. Even $10 a month, invested over 18 years at a 6% average return, grows to nearly $3,900. Start with what you can manage without strain and increase it when you're able.
What is the best way for grandparents to save money for grandchildren? The best account depends on your goals. 529 plans offer tax advantages for education expenses and are the most popular choice. Custodial accounts (UGMA/UTMA) are more flexible but have fewer tax benefits. U.S. savings bonds are safe and simple. See our full guide to grandparent savings accounts for a detailed comparison.
Can grandparents on a fixed income save for grandchildren? Yes. Small, consistent contributions make a real difference over 18 years. Even $5–$10 a month, redirected from everyday spending or contributed from occasional windfalls like tax refunds, adds up meaningfully when invested early.
Should grandparents give gifts or contribute to savings? Many grandparents find a balance works best: a small gift for the occasion paired with a savings contribution. As grandchildren get older, they often come to value and understand the savings contribution more than physical gifts.
