A Grandparent's Guide to Investing for Grandkids

You have the two things that build a grandchild's wealth best — time and intent. The accounts, the tax basics, and how to make it a lesson, not just a gift.

Grandparents are in an almost unfair position to build a grandchild's wealth — and it is a gift that keeps compounding. If you have the desire to help, you likely also have the two ingredients that matter most: time and intent.

Why grandparents have the edge

Start at a grandchild's birth and the money has the longest possible runway to compound. Grandparents are also often at a stage where they can give without straining their own finances. Put those together and a modest, early gift can quietly become a life-changing sum by the time the child is an adult.

The main ways to do it

OptionBest for
529 planEducation, tax-free growth, and keeping control of the account yourself
Custodial account (UTMA)Flexibility — usable for anything that benefits the child
Custodial Roth IRATax-free growth once the grandchild has earned income from a job
Your own brokerage accountFull control over timing, earmarked for the grandchild

Not sure which fits? The 529 vs. UTMA comparison walks through the trade-offs.

Two things worth knowing

  • Gift tax rarely bites. Gifts are generally covered by the annual gift-tax exclusion — a set amount per recipient, per year, that most families never exceed.
  • The financial-aid update. Under the newer FAFSA rules, money from a grandparent-owned 529 no longer counts against a grandchild's aid the way it once did — removing the old reason grandparents avoided them. (Details in custodial accounts & financial aid.)

Tax and aid rules change and vary by state — MemoryBank is an education and display tool, not a financial advisor. Confirm the specifics with a CPA or fee-only planner.

The part that isn't about money

The biggest gift may be teaching, not just funding. Watching an account grow together — grandparent and grandchild — turns a transfer of money into a shared lesson. That is exactly what MemoryBank is built for: a dashboard the grandchild can actually understand, showing what you started for them.

What to do this month

  1. Decide the goal: education (529), flexibility (UTMA), or retirement for a working teen (Roth).
  2. Have a five-minute chat with the parents — you'll likely need the child's SSN.
  3. Open the account and fund it.
  4. Connect it so you and your grandchild can watch it grow together.
