Best Debit Cards for Kids (2026): Monthly Fees Compared

Step is the cheapest kids' debit card in this comparison. Its FAQ says it has no monthly, overdraft, minimum or account management fees, and it is built for teens. Among cards that do charge a monthly fee, FamZoo's 12-month prepay is the lowest at $59.90 a year, and Greenlight Core ties FamZoo's monthly plan at $5.99 a month for the whole family. Prices checked October 12, 2026.

This page compares what each card charges every month, what that price covers and how many children each card serves. Every figure comes from the vendor's own page, read on October 12, 2026. We left out savings rates, since they are a return rather than a cost, and kept to the fee a family pays each month.

Monthly fees at a glance

The yearly figure is the monthly price times twelve, except FamZoo's prepay row, which shows the printed total. Greenlight and FamZoo quote one price for the whole family, so the bill does not rise with each child. Acorns quotes a price per plan and a card limit, and the card limit is the first thing to check for a larger family. Our analysis of the yearly column puts the gap between the cheapest and the dearest plan at $239.76 a year, from Step's $0 to Greenlight Family Shield.

Step: no monthly fee, built for teens

Step is the only card in the table with no monthly fee, according to its FAQ page. Its FAQ calls it a free banking platform for teens, young adults and families, and says there are no monthly, overdraft, minimum or account management fees. For a family whose child has a phone, that makes it the default starting point. Each teen opens a separate account on a separate phone. A younger child with no phone can have a parent-managed account instead. Step says those are free, but they have no separate login for the child. A parent who also sends money to the teen can compare the transfer side in payment app fees compared.

Step's card is a Visa card. Its Smart Pay feature pays each charge in full, and Step says that means a teen cannot overspend. A parent who wants to head off overspending will like that rule. Step says it is not a bank. Its accounts run through Evolve Bank & Trust, a member FDIC, and the FAQ says deposits are insured up to $250,000 through that partner.

The table counts monthly prices only. Charges on individual transactions are outside the comparison, so a family that expects frequent transfers or withdrawals should read those charges before the teen starts using the card.

Greenlight: up to five kids on every plan, and the higher plans charge for features

Greenlight sells four plans for the whole family on its plans page, running from Core up to Family Shield. Every plan includes debit cards for up to five kids, which covers larger families than Acorns' four-card limit. FamZoo has no cap at all, so the choice between those two comes down to fees and features. Core adds chores, jobs, allowance and direct deposit, the LevelUp financial literacy game and stock browsing. What Core leaves out costs more to add. The 1% cash back on purchases starts at Max, and family location sharing starts at Infinity.

The step-ups are priced by feature, so the arithmetic is worth doing. Moving from Core to Max adds $4.99 a month, or $59.88 a year. Cash back at 1% covers that gap only when the card carries about $499 of spending a month. Greenlight also attaches conditions to the cash back: the primary account must be in good standing and have a verified ACH funding account.

Families who want location sharing pay $9.99 a month more than Core to get it through Infinity, which is $119.88 a year. Family Shield costs $9.00 a month more than Max, or $108 a year, and it bundles the Infinity features with financial account monitoring, instant credit lock and up to $1 million in identity theft coverage. Those protections suit some households, but they are not kids' features. A family that wants a card and chores can stop at Core.

Greenlight's footnotes add two conditions to the monthly price. Depending on where you live, taxes may be added to the subscription. The first monthly fee is billed seven days after sign-up, but a request to close the account before that first billing date gets the fee refunded. That gives a new family a short window to try the card before the fee sticks.

FamZoo: no cap on cards, and prepaying cuts the price

FamZoo charges per family, and its home page says there are no limits on family members or cards. That matters for a household with more children than Greenlight's five, because adding a child does not change the bill.

FamZoo is a prepaid card rather than a bank account. Its page says no bank account is needed, that families can reload from a digital wallet or from a government agency's direct deposit, and that funds held on the card are FDIC insured. It also says the card carries Mastercard's Zero Liability policy for unauthorized purchases. For a household with no bank account, that protection matters more than the price. For the bank side of the trade-off, checking vs savings accounts explains how the two account types differ.

The monthly plan costs $5.99 with a one-month free trial, which takes one payment off the first year. The 12-month prepay costs $59.90, which is $11.98 less than twelve monthly payments. The page also adds an extra free month, which stretches that prepay to 13 months, or about $4.61 a month. A family that expects to stay a year should prepay. The page says a monthly plan can switch to prepay at any time, so a family can start monthly and change later.

Acorns Early: $8 a month, for ages 6 to 18, with a four-card limit

Acorns Early is for kids aged 6 to 18. The Lite plan costs $8 a month and includes a smart money app, up to four debit cards, automatic allowance and tasks, real-time spending notifications, card locking and spend-category blocking. Gold costs $12 a month. Its FAQ says Acorns Early is included in every Gold subscription, and Gold adds Acorns Early Invest, Acorns Invest and Acorns Later. Those are investment and retirement accounts, and a family that only needs a kids' card gains nothing from them. The $4 difference works out to $48 a year.

Set against Greenlight Core for two children, Acorns Lite costs $24.12 more a year, at $96 against $71.88. The four-card limit matters more than the price. A family with five children cannot put all of them on one Acorns plan, while Greenlight covers up to five and FamZoo has no cap. Acorns says the Early card is issued by nbkc Bank under a Visa license and by Community Federal Savings Bank under a Mastercard license, and both are FDIC members.

Acorns' growth calculator has a footnote that mentions a $4 monthly minimum without naming a plan. No plan at that price is named, so this table uses the Lite price.

Which card fits which family

• A teen with a phone: Step, which has no monthly fee and gives each teen their own account.
• A family with up to five children that wants chores and allowance tools for a flat monthly fee: Greenlight Core.
• A family with more than five children, or no bank account: FamZoo, with its per-family fee, no card limit and the lowest yearly cost among the cards with a monthly price once prepaid.
• A family already using Acorns: Acorns Early Lite. Choose Gold only if a parent wants the investing and retirement accounts it adds.
• A family that wants location sharing and SOS alerts: Greenlight Infinity, the first Greenlight plan that includes them.

Methodology: how we checked the prices

We read each vendor's own page on October 12, 2026: Greenlight's plans page, including its feature table and footnotes, FamZoo's home page where its monthly and prepay plans appear, Acorns' Early page with its pricing and FAQ, and Step's FAQ page. Prices are the monthly list prices each vendor prints. Yearly costs are that price times twelve, or the printed total where a plan has one. The comparison covers four vendors. Bank-issued teen accounts and other kids' apps are outside it. We did not open accounts or use the cards. Our full method is on the how we rate page.

This page is general information, not personalized financial advice. Vendors change plan prices and features, so treat these figures as a snapshot from October 12, 2026.
