Here's a sentence you probably never expected to read: Cash makes teenagers spend more recklessly. But according to new survey data from Cash App, that's exactly what's happening with Gen Z.
For parents trying to figure out when—or whether—to hand their teenager a debit card, the financial landscape has completely changed. Digital payments are now the default for young people, and the data suggests that physical money might actually be the problem, not the solution.
The Cash Paradox
Cash App's Gen-Z Financial Future survey uncovered a striking generational shift. More than half of Gen Z respondents admitted they're more likely to spend impulsively when holding cash. Nearly a third view people who use cash as "out of touch" or even "cringe." And 53% said they only use physical money as a last resort.
It's the opposite of what many parents were taught—that carrying cash helps you visualize spending and makes you more cautious with money. For Gen Z, apparently, cash feels like play money that doesn't really count.
The survey also revealed some concerning savings patterns. About 46% of Gen Z respondents reported having less than $500 saved, and only 44% knew the interest rate on their savings account. These numbers suggest that while young people are comfortable with digital finance, they're still figuring out how to make it work for them.
Why Debit Cards Are Winning
Despite the risks that come with any form of spending, debit cards are becoming a popular tool for teaching financial responsibility. Most major banks now allow teens as young as 13 to open checking accounts with a parent or guardian as a co-signer, according to Bankrate.
And parents seem to think it's working. The Cash App survey found that parents of teens ages 13-17 reported meaningful benefits after giving their children access to debit cards or savings accounts. They said it increased their teen's financial independence, encouraged more responsible spending, and helped build budgeting confidence.
The key difference? Oversight and structure. Unlike handing over $50 in bills and hoping for the best, debit cards give parents visibility into transactions and the ability to set limits while still letting teens practice real-world money management.
Interest Rates Actually Matter to Teens
Here's something encouraging: Over three-quarters of Gen Z survey respondents said they'd save more if they were earning interest on their money. That's a pretty sophisticated understanding of how savings should work, and it suggests teens are paying attention when there's something in it for them.
Cash App recently expanded its 3.5% APY savings feature to Sponsored Accounts for teens ages 13-17, responding directly to this demand. And teens aren't just parking money for no reason—about 46% are building emergency funds, 36% are preparing for major milestones like college or moving out, and 37% are saving for experiences like travel.
That's actual financial planning, not just saving birthday money in a shoebox.
How to Know If Your Teen Is Ready
Not every teenager is ready for a debit card at the same age, but financial experts at Bankrate suggest watching for a few key indicators:
- They're earning money. A first job or side hustle creates a natural need to manage income beyond just spending what parents provide.
- They're driving. Having a debit card means teens can cover gas, parking, or handle unexpected expenses without constantly calling for help.
- They frequently ask for money. If your teen is constantly requesting funds, tying a debit card to an allowance or stipend can shift the conversation from "Can I have money?" to "How should I budget what I have?"
But readiness isn't just about the teen—it's also about the parent. Bankrate emphasizes that parental involvement matters enormously. Setting clear rules, reviewing transactions together, and holding regular money check-ins can make the difference between a debit card becoming a teaching tool or a free-for-all.
The New Normal
The broader picture here is that digital payments have become the default for an entire generation. For Gen Z, swiping a card or tapping a phone feels more real and trackable than carrying cash, which somehow registers as both outdated and easier to waste.
That's a fundamental shift from how many parents learned about money, and it means the old rules don't necessarily apply anymore. With proper guardrails—parental oversight, spending limits, and ongoing conversations about budgeting—debit cards can help teens build confidence and establish healthy financial habits before they're fully on their own.
The data suggests we're not talking about giving teens unlimited access to money. We're talking about giving them structured practice with the payment methods they'll actually use as adults, in an environment where mistakes are small and guidance is close at hand.
