When Should You Start Your Kids and Grandkids on Financial Planning?

Start sooner than most families think, and treat it as a decade-long process rather than a single conversation. Basic money habits can begin in early childhood, around ages five to seven, with saving and spending; investing concepts and a first custodial or Roth account fit the teenage and early-working years; and candid discussion of the family's actual wealth and estate plans usually belongs in the twenties or thirties, staged as maturity and circumstances warrant. The two questions, when to teach money skills and when to disclose family wealth, are different and deserve different timelines. Skills should start early and build continuously; disclosure of significant wealth should be deliberate, gradual, and tied to readiness rather than a fixed birthday. Families who delay both until a sudden inheritance often find that heirs receive money without the preparation to handle it, which is the outcome thoughtful planning is meant to avoid.

Why does starting early matter?

Financial capability is learned, and like any skill it develops through years of practice, not a one-time briefing. Children who grow up making small money decisions, saving for a goal, spending within a limit, seeing the trade-offs, build judgment that no single conversation at 25 can replicate. For families with significant wealth, the stakes are higher: heirs who inherit without financial fluency or shared values are more likely to mishandle what they receive. The folk statistic that most family wealth dissipates within a few generations is often cited and is hard to verify, so we do not present it as fact; the underlying concern, that unprepared heirs struggle, is well supported by the experience of advisers and family-office professionals. Starting early is how families convert that concern into preparation. This complements the governance work in preparing heirs.

What is age-appropriate at each stage?

The content should match the child's developmental stage. The following is a general progression, not a rigid schedule.

In early childhood (roughly ages 5 to 10), the lessons are concrete: the idea that money is finite, the difference between saving and spending, and the satisfaction of saving toward a small goal. An allowance tied to choices, with a portion set aside, teaches more than any lecture.

In the adolescent years (roughly 11 to 17), introduce earning, budgeting, the basics of how investments grow, and the concept of compounding. A custodial account or a part-time job creates real stakes. This is also when charitable giving can become a family practice, letting children direct modest gifts and learn the values behind them.

In early adulthood (the late teens through the twenties), the focus turns to independence: managing a checking account and credit responsibly, understanding student debt, starting to invest, and, for those with earned income, opening a Roth IRA early to harness decades of tax-free compounding. A first job is also the moment to introduce retirement-plan basics.

When should you fund accounts for children and grandchildren?

Funding can begin at birth, and the structure should match the purpose. Several vehicles work together.

A 529 plan is the workhorse for education, with tax-free growth and, in many states, a contribution deduction; grandparents often front-load these, as we cover in 529 superfunding. A custodial account (UTMA) holds assets for a child until they reach the age of majority, at which point the child controls the money, an important caveat for larger sums. A custodial Roth IRA, funded once the child has earned income, is among the most powerful long-term tools because of the compounding runway. Newer vehicles continue to appear; we cover one in the Trump accounts guide. The choice among these depends on the goal, the amount, and how much control you want the child to have and when.

When should you tell children about the family's wealth?

This is the harder question, and the answer is "gradually, and tied to maturity," not a single reveal. Disclosing significant wealth too early can sap motivation or distort a young person's choices; disclosing too late, or never, leaves heirs unprepared and can breed mistrust or poor decisions when wealth suddenly appears.

A staged approach works best. Younger children need values and habits, not balance sheets. Teenagers can understand that the family is fortunate and that wealth carries responsibility, without specific numbers. Adult children, typically in their twenties and thirties, can be brought into more concrete discussions of the estate plan, the structures involved, and eventually the magnitude, in steps that match their demonstrated maturity and their role. Many families formalize this through family meetings, a shared mission or values statement, and a gradual introduction to the advisers and structures involved, the governance approach described in preparing heirs and the coordination of the personal CFO model. The goal is that by the time wealth transfers, it is not a surprise but the next step in a long, prepared conversation.

A worked example: a staged plan

The following is a hypothetical illustration. A family with substantial wealth begins when their daughter is six: an allowance split into save, spend, and give. At twelve, she helps choose a charity for the family's annual gift and watches a small custodial account she helped pick rise and fall. At sixteen, with a summer job, she opens a custodial Roth IRA and learns why starting early matters. In college, she manages her own checking and a modest investment account. At twenty-six, with a stable job and demonstrated judgment, her parents walk her through the broad outline of the estate plan and the trusts that will one day involve her, introducing her to the family's adviser. By her thirties, she understands the magnitude and her future responsibilities. No single conversation carried the weight; a fifteen-year process did. The example is hypothetical, but the staging is the point.

Frequently asked questions

At what age should kids start learning about money?Basic concepts, saving, spending, and that money is finite, can start around ages five to seven through an allowance and small goals. Financial education works best as a continuous process that deepens with age, not a single talk.

When should I open an investment account for my child?You can start at birth with a 529 for education. A custodial Roth IRA can begin once the child has earned income, which maximizes decades of tax-free compounding. The right vehicle depends on the goal and how much control you want the child to have.

When should I tell my children how much money the family has?Gradually, tied to maturity rather than a fixed age. Share values and responsibility early, broad concepts in the teen years, and concrete details of the estate plan and magnitude in the twenties and thirties as readiness is demonstrated.

Will telling my kids about family wealth reduce their motivation?It can if done abruptly or too early, which is why a staged approach matters. Pairing disclosure with responsibility, work, philanthropy, and involvement in family decisions, tends to build motivation and stewardship rather than entitlement.

How do grandparents fit into this?Grandparents often fund 529s and other accounts and can be powerful teachers of values and giving. Coordinating their gifts with the parents' plan keeps the education consistent and avoids unintended tax or benefit consequences.
