Monzo Kids Account: Under 16s Debit Card & Savings Account Guide
Handing a child their first debit card used to mean a branch visit, a parent's signature, and a stack of paperwork. Monzo changed that. The Monzo kids account, officially called Monzo for Under 16s, lets a parent set one up in a few minutes straight from a phone.
Who qualifies, what it costs, which parental controls exist, how the savings side pays interest, how it compares to GoHenry, Starling, and the high street banks still handing out paper passbooks to nine-year-olds — that's what this guide covers. By the end you'll know whether it's the right first account for your child.
What Is the Monzo Kids Account? Monzo for Under 16s Explained
Monzo for Under 16s is a free banking product for children aged 6 to 15, built as an extension of a parent's own Monzo account. The child gets their own login, their own coloured debit card and a simplified view of their money inside the Monzo app. The parent keeps full oversight from their side.
It can't exist on its own. The Under 16s account is tethered to an adult's Monzo current account, and that's deliberate — it keeps a responsible adult in the loop on every transaction while the child still gets real independence over how they spend and save.
A few things worth knowing about the Monzo kids account:
- It's completely free — no monthly fee, no subscription, no top-up charge
- Available to children aged 6–15 who are UK residents
- The child gets their own physical debit card, available in several colours
- Parents can view spending, set limits, and freeze the card instantly from their own app
- A second family member (like a grandparent) can be given limited access too
- The account includes an optional savings feature that pays interest
Call it a monitored sub-account bolted onto a Monzo current account rather than a bank account in the traditional sense. That's also why the setup starts with the parent, not the child.
Who Can Open a Monzo Account for Under 16s?
The eligibility rules are stricter than they look at first. Monzo requires the applying adult to already be a customer, and the child needs to meet a specific age and residency bar.
What's actually required:
- Open or already hold a Monzo current account. You can't add a Monzo account for under 16s without first being a Monzo customer yourself — this is the account it plugs into.
- Confirm you're the parent or legal guardian. Monzo only allows a parent or guardian to open and manage the account, not another relative or family friend as the primary holder.
- Check your child's age. They need to be between 6 and 15 years old. Once they turn 16, the account automatically evolves into a different product.
- Confirm UK residency. Both the parent's account and the child using the Under 16s account need to be based in the UK.
- Open the account from your app. From the parent's Monzo app, there's a dedicated flow to add a child, verify their details, and order their card.
- Hand the phone (or a spare device) to your child. They'll need the Monzo Kids app or a linked view to log in and see their own balance.
The whole thing usually takes a few minutes, not days. That speed is one of the account's biggest selling points against the high street alternatives.
Monzo Kids Account Features and Parental Controls
This is where the Monzo account for under 16s earns its reputation. Parents get real-time visibility without logging into anything separate; it all lives inside the same Monzo app they already use for their own current account.
Parental controls and child account features include:
- Spending limits — set a daily cap on how much the child account can spend
- Cash withdrawal toggle — allow or block ATM withdrawals entirely
- Online payment toggle — switch off card-not-present transactions if you're not ready for that yet
- Instant freeze — lock the card the moment it's lost or misused, with no phone call required
- Push notifications — get an alert every time the child spends, so there's no end-of-month surprise
- Sort code and account number — the child account gets its own real account details, so pocket money, birthday cash, or payments from family can be sent directly
- Apple Pay and Google Pay — unlocked once the child turns 13
- Second family member access — a grandparent or other relative can be added with limited permissions to send money or check in
The card itself is a genuine Mastercard debit card, not a closed-loop prepaid one, so it's accepted anywhere Monzo's adult cards work. That's a real difference from some prepaid-only kids' cards, which occasionally get rejected at certain terminals — a neon card that actually functions everywhere matters more than it sounds.
Monzo Under 16s Savings Account and Interest Rates
Alongside the spending card, Monzo offers an Under 16s savings account, shown in the app as a savings "Pot." The point is to make saving visible, not just a static number in an account nobody ever checks.
It pays a variable AER, generally quoted around 2.75–3% (check the current rate in the app or on Monzo's site, since it moves with the base rate). Interest is calculated daily and paid monthly, so a child watches their balance nudge upward every few weeks. That's a small trick, but it works — interest on their savings stops being an abstract idea once they can actually see it land.
| Feature | Detail |
|---|---|
| Interest rate | Variable AER, roughly 2.75–3% (check current rate) |
| Interest payment frequency | Monthly, calculated daily |
| Maximum savings balance | £10,000 per child |
| Account type | Instant access — no lock-in period |
| Linked to | The child's Under 16s current account |
| Cost | Free, no fees |
Being instant access means a child, with parental sign-off where relevant, can move money between spending and saving without waiting days for a transfer to clear. Younger kids especially need that — the gap between "saving for something" and "saving because a parent told them to" is a real one, and flexibility helps close it.
How the Monzo Current Account Compares to Other Kids' Cards
Monzo isn't the only digital-first option out there. GoHenry pioneered the category, Starling runs a close parallel to Monzo's own approach, and most high street banks still offer something, usually far more basic.
| Provider | Monthly cost | Age range | Parental controls | Educational tools |
|---|---|---|---|---|
| Monzo for Under 16s | Free | 6–15 | Spending limits, freeze card, notifications | Basic in-app money guides |
| GoHenry | Paid subscription | 6–18 | Spending limits, task-based allowance, chores | Gamified lessons, quizzes |
| Starling Kite (Under 16s) | Free | 6–15 | Spending limits, freeze card, notifications | Basic in-app guides |
| Typical high street bank | Free | Varies, often 11+ | Limited — usually just balance visibility | Minimal or none |
Laid out side by side, the trade-off gets pretty clear. Monzo and Starling compete almost head-to-head on being free and app-native, with strong real-time controls but fairly light educational content. GoHenry charges a monthly fee for the privilege of leaning harder into structured financial education: chores tied to pocket money, gamified saving goals, quizzes built around habits rather than pure visibility.
A high street bank account wins on brand familiarity and in-branch support, but loses badly on the app experience and instant controls that most parents now expect by default. Real-time visibility and zero fees? Monzo's current account for kids is hard to beat. Structured money lessons worth paying for? GoHenry earns its fee.
What Happens When Your Child Turns 16 or 18?
This account isn't static. It's built to grow with the child, and that's part of what separates it from a basic prepaid card that just expires one day.
At 16, the Under 16s account transitions into a 16-17s account automatically. The child keeps their card, their transaction history and their savings, and gains a bit more independence, though parents still retain some oversight during this stage. No reapplying, no fresh account — turning 16 just triggers the upgrade in the background.
At 18 it happens again: the 16-17s account becomes a standard, full adult Monzo current account. Parental visibility ends entirely at that point. The account works like any other adult Monzo account, with its own credit and overdraft eligibility and its own full feature set, no link back to a parent. A family that's stuck with Monzo the whole way through ends up with a kid who's fully financially independent without ever switching banks.
Teaching Kids About Digital Money — From Monzo Pots to Crypto Payments
What's interesting about Monzo's approach isn't really the card. It's the shift in how a whole generation is learning to handle money. Cash pocket money is fading fast. Kids now grow up watching balances update instantly, moving money into savings Pots with a tap, treating "money" as something that mostly lives on a screen.
That same shift shows up well beyond family banking. Businesses and individuals increasingly manage payments digitally too, and a growing slice of that now includes cryptocurrency alongside cards and bank transfers. Parents or business owners curious how digital and crypto payments actually work can take a look at Plisio, which offers a fairly simple way to accept and manage cryptocurrency payments — a natural next step once the basics, taught early through something like a Monzo account, start to click.
Final Thoughts
If what you want is real visibility into how your child spends and saves, without a branch visit or a monthly fee, this is genuinely hard to beat. One account covers the spending card, the interest-bearing savings, and the automatic step-up to a full adult product at 18.
Does it beat GoHenry or Starling or the bank down the road? Depends what you care about more — control and zero fees, or lessons worth paying extra for. Either way, it's a low-risk way to hand a child their first real taste of managing money.
