Best ETFs for Kids

Before the fund, the account. The most common vehicle is a custodial brokerage account, a UGMA (Uniform Gifts to Minors Act) or UTMA (Uniform Transfers to Minors Act) account, which lets an adult invest on a child's behalf. The adult is the custodian and controls the investments, but the assets legally belong to the child and transfer to their control at the age of majority for your state (often 18 or 21). It can hold any ETF, stock, or fund, and it is the most flexible option because the money is not tied to a specific use.

A second vehicle is a custodial Roth IRA, which grows tax-free but is available only if the child has earned income, such as wages from a job, with contributions capped at that earned income. A third is a 529 plan, built specifically for education, which offers tax-free growth when used for qualifying school expenses but earmarks the money for college. If college is the specific goal, our best ETFs for college savings guide covers 529s and the broad funds people hold inside them in more depth. The vehicle you choose decides who controls the money, when, and how it is taxed; the fund choice inside it is the next step.

A child's account often has the single longest time horizon any investor will ever have. A newborn's custodial account can stay invested for close to two decades before the child reaches the age of majority, and a custodial Roth IRA can run far longer than that. A long horizon is the main reason broad, growth-oriented equity funds appear so often in these accounts: there is decades of room for the market to recover from downturns, so short-term volatility matters less than it would for money needed soon.

That is why funds like VTI (total US market), VOO (S&P 500), and VT (total world) are common picks here, and why some families add a growth tilt on top. Conservative holdings like bonds, which lower volatility, are used more for money that will be needed sooner. For more on the long-horizon framing generally, see our best ETFs for long-term growth guide. None of this is a recommendation; it is the reasoning behind why these funds recur.

For a US core, VOO holds the S&P 500, the roughly 500 largest US companies, and VTI holds the total US market, several thousand stocks including the mid- and small-cap tail, both at around 0.03%. They overlap almost completely at the top, so most people hold one, not both. For a single-fund global core, VT bundles the US and international markets into roughly 9,500 stocks in one ticker, which means no rebalancing between US and abroad over an 18-year hold.

Some parents add a growth tilt on top of that broad core. VUG (large growth) and SCHG (Schwab large growth) lean into the faster-growing, more technology-heavy names, and QQQ tracks the Nasdaq-100. Growth funds are more concentrated and more volatile than a total-market fund, which is why they are usually layered as a satellite on a broad core rather than used alone. If you are starting from scratch, our best ETFs for beginners guide walks through the same broad cores in more detail.

Compounding is the reason a child's account is such a distinctive case: returns earn returns, and the longer the money is left alone, the more that effect dominates. Over a childhood, the bulk of an account's final value can come not from the contributions themselves but from the growth those contributions earned over ten or twenty years. The earlier money goes in, the longer it compounds, which is why starting early matters more than starting large.

Consider one illustrative example: a parent puts a fixed amount into a broad fund like VTI when a child is born and holds it for 18 years, untouched, reinvesting dividends along the way. Over that span, a broadly diversified equity fund has historically grown meaningfully, though past performance is not a guarantee and the path is never a straight line. The point of the example is the mechanism, not a projected number: a long, undisturbed hold is what gives compounding the time it needs. Markets fall and recover; an account with 18 years ahead of it has room to ride through that.

The most durable child accounts are usually the simplest: one or two broad funds, not a sprawling collection. A single total-market or S&P 500 fund, optionally with a global or growth tilt, covers the ground that a dozen overlapping ETFs would, with less to manage over 18 years. Holding many funds that all stack the same mega-caps (for example VOO, QQQ, and VUG together) adds complexity without adding much diversification.

Cost compounds the same way returns do. The expense ratio, the annual fee each fund charges, is subtracted every year for the life of the account, so the cheap broad funds (around 0.03% for VOO and VTI) keep more of the growth than pricier ones. Many families also make small, regular contributions rather than waiting for a lump sum: most brokers offer commission-free ETF trades and fractional shares, so a modest monthly amount buys into a fund like VTI automatically. Low-cost, simple, and steady is the pattern that tends to hold up over a childhood.

One thing that sets a child's account apart is the kiddie tax, a US rule that can tax a child's unearned investment income above an annual threshold at the parents' tax rate rather than the child's lower rate. It applies mainly to custodial UGMA/UTMA accounts that generate dividends or realized capital gains, and it is the reason some families lean toward broad, low-turnover funds that throw off less taxable income year to year.

A custodial Roth IRA and a 529 plan work differently: both offer tax-advantaged growth (tax-free in a Roth, tax-free for qualifying education expenses in a 529), which sidesteps the kiddie-tax question on growth inside them. This is a general description of how the rules are structured, not tax advice. Thresholds and rules change, and how they apply to your family is specific to your situation, so confirm the current details with a tax professional. Walnut is not an investment adviser or a tax adviser.

Figures and holdings are approximate as of early 2026; verify the current expense ratio and composition on each issuer's site. Notice the through-line: every fund here is broad, cheap, and meant to be held for years, which is exactly what a child's long horizon is built for.

The hard part of investing for a child is rarely picking the fund; it is keeping the account simple, low-cost, and consistent over many years without second-guessing it. That is where an AI assistant can help, because it can reason over a real account rather than a generic checklist. The useful questions are specific: does this growth fund overlap with the broad core I already hold, how has a fund like VTI done against the S&P 500, and is the account drifting away from the simple structure I set up.

That is where Walnut fits. It connects a brokerage through SnapTrade and lets you ask, in plain language through Claude, ChatGPT, or a built-in assistant, how a fund fits a long-horizon account, how much a new holding overlaps with what is already there, and how each position is doing against the market. It is read-only by default, and you approve any trade. Walnut is not an investment adviser; it helps you see and act on your own portfolio rather than telling you what to buy for a child.

Investing for a child comes down to two decisions: the account and the fund. The account is usually a custodial UGMA/UTMA brokerage account, a custodial Roth IRA if the child has earned income, or a 529 for college specifically. The funds most commonly used are broad and low-cost, because a child's account can hold the longest horizon any investor gets: VOO or VTI for a US core, VT for a global core, and a growth tilt like VUG, QQQ, or SCHG for families who want one. Keep it simple, keep it cheap, contribute steadily, and let compounding work over the years.

The long horizon is the real edge here, and the kiddie tax is the one wrinkle worth understanding before you start. From a connected account you can dig into any of these as an ETF, look at an individual stock one of them holds, or explore a theme you want a child's account exposed to. Holdings, fees, and tax rules change, so treat the specifics here as a starting point and confirm on each provider's site, and with a tax professional, before deciding.
