What Is UNest?
UNest is a mobile app that lets parents open and fund an investment account for their child. Rather than a bank savings account earning next to nothing, UNest puts contributions into diversified, low-cost ETF portfolios so the money has a chance to grow over the 15–20 years until the child is an adult.
The account UNest opens is a custodial account under the Uniform Transfers to Minors Act (UTMA). The parent or guardian controls the account until the child reaches the age of majority in their state — usually 18 or 21 — at which point the assets become legally the child's. UNest has been named one of the best custodial account options by mainstream outlets and carries a strong app-store rating from hundreds of thousands of reviews.
UNest is available on iOS and Android. It's designed to be fast to set up and mostly hands-off: you choose a portfolio, set a monthly contribution, and let it run.

How UNest Works
Getting started is simple. You download the app, enter some basic details about yourself and your child, choose an investment portfolio based on how much risk you're comfortable with, and set an initial and recurring contribution amount. From there, UNest handles the investing automatically.
The gifting feature is where UNest separates itself from a plain brokerage custodial account. You get a shareable link that lets grandparents, aunts, uncles, and friends contribute directly to your child's account. Instead of another toy that gets forgotten, relatives can add to a fund that compounds for years. Gifts can be set up to recur, which is popular with grandparents who want to contribute every month.
Because it's a UTMA account, the funds are flexible: unlike a 529 plan that locks money into education expenses, UTMA money can go toward a first car, a deposit on an apartment, starting a business, or anything else that benefits the child once they come of age.
UNest Pricing & Fees
UNest is a subscription service, and this is the single most important thing to understand before signing up. As of late 2026, UNest advertises no fees on balances up to $300 for the first 12 months, after which it charges a low monthly subscription (around $2/month) plus a small annual fee on invested assets (roughly 0.25%).
UNest has changed its pricing more than once over the years — earlier members may be grandfathered onto older plans, and some past reviews quote different monthly figures. Always confirm the current price inside the app before you commit.
Here's the honest math: a flat monthly fee is a larger percentage drag when your balance is small. On a $500 balance, $2/month is about 4.8% a year — high. On a $10,000 balance, that same $2/month is only about 0.24% — very reasonable. UNest makes the most sense once you're contributing regularly and the balance grows into the thousands, where the fee becomes a rounding error relative to the convenience and gifting features.
UNest vs. a Free Brokerage Custodial Account
This is the comparison that matters most. UNest opens a UTMA — and so do most major brokerages, usually with no monthly fee at all. So what are you paying UNest for?
| Feature | UNest | DIY Brokerage UTMA | 529 Plan |
|---|---|---|---|
| Account type | UTMA custodial | UTMA custodial | Education savings |
| Monthly fee | ~$2/mo + ~0.25%/yr | Usually $0 | Usually $0 (plan fees apply) |
| Setup effort | Minutes, from your phone | More setup, DIY | Moderate |
| Family gifting link | ✓ Built in | ✗ Not typical | Some plans |
| Pre-built portfolios | ✓ Yes | You choose funds | ✓ Age-based |
| Use of funds | Anything for the child | Anything for the child | Education only (tax-free) |
| Tax advantages | Limited (UTMA rules) | Limited (UTMA rules) | Strong for education |
You're paying UNest for convenience and the gifting feature, not for access to anything you couldn't get elsewhere. For parents who would never get around to opening a brokerage custodial account on their own — and who want family to contribute easily — that convenience is worth the fee. For hands-on investors chasing the lowest cost, a DIY UTMA wins. And if your sole goal is college and you want the best tax treatment, a 529 plan is usually the better vehicle.

If you want the easy, automated route — and want grandparents to pitch in — UNest gets you set up in minutes.
Open Your UNest Account →Who Should Use UNest
UNest is a good fit if you are:
- A busy parent who wants to start investing for a child without the hassle of setting up a brokerage account
- Someone who wants family — especially grandparents — to contribute easily via a shared gifting link
- A fan of "set it and forget it" automated monthly investing
- Looking for flexibility — a fund that can be used for more than just college
UNest is probably not for you if you are:
- A cost-focused investor who would happily open a free custodial account at a major brokerage
- Saving specifically and only for college — a 529 plan usually offers better tax treatment
- Starting with a very small balance where a flat monthly fee is a large percentage drag
- Uncomfortable with the child gaining full control of the money at 18 or 21 (a feature of all UTMA accounts)
