A $200 jacket becomes four payments of $50. The math feels painless at checkout, almost like a magic trick.
Then a second purchase shows up a week later, split the same way.
Then a third.
Soon the calendar is full of due dates from different apps, each one small enough to ignore until it isn’t.
That pattern now has a name and a number attached to it.
How one small payment turns into a stack of them
The appeal of buy now pay later is built on a simple trick of framing. Instead of seeing one price, a shopper sees a smaller first installment due today and three more spaced two weeks apart. That reframing makes a $200 purchase feel like a $50 decision, lowering the resistance that normally makes people pause before spending.
Nothing stops a shopper from doing that same trick again at a different store an hour later. Each provider only sees its own loan, not the others a person may have open elsewhere. So the four easy payments promise multiplies quietly in the background, invisible to any single lender.
That is the mechanical root of what regulators call loan stacking. The Consumer Financial Protection Bureau found that 63 percent of buy now pay later borrowers had multiple loans open at the same time at some point during 2022, a sign that the overlap is less the exception than the norm. It is not that any individual plan is unaffordable. It is that several small plans layered together eventually demand a lump sum the budget was never built to cover.
The checkout habit spreading from gadgets to groceries
Buy now pay later started as a way to split the cost of furniture, electronics and concert tickets. That has changed fast, and groceries are now part of the pattern. A LendingTree report found that nearly a third of users have used these short-term loans to buy groceries, up from 14% two years earlier.
Even more telling is what happens once someone starts using the plans regularly. LendingTree’s most recent tracking shows most users don’t stop at one loan. One in four BNPL users has held three or more active loans at once, up slightly from the year before.
Younger shoppers lead by a wide margin. Among Gen Z users, 29% have held three or more loans at once. For millennials, the figure is 28%. LendingTree’s chief consumer finance analyst, Matt Schulz, has said consumers are leaning on these loans more often and juggling more of them at once.
That stacking habit has a lot in common with tap-to-pay spending, where removing friction from a purchase makes total spending easy to lose track of until the bill arrives.
What the newest numbers show about missed payments
LendingTree’s latest survey, fielded among roughly 2,000 US adults, is the most current look at how the habit plays out in practice. It found missed payments climbing alongside the stacking trend, not separately from it. Specifically, 47% of users say they have paid late within the past year, up six points from the year before and 13 points from two years prior.
That is a steady multi-year climb, not a one time blip.
Separate Bankrate research backs the pattern with its own sample, finding overspending and regret among the most common complaints reported by users.
Where the stacking problem hits hardest and what it doesn’t prove
The complication is that stacking does not hit every user the same way. Bankrate’s data shows a sharp generational split: 66 percent of Gen Zers reported at least one problem while using these plans, the largest share across any age group. Older users report far fewer issues.
Even so, the picture is not uniformly bleak. Most individual loans still get repaid, and CFPB figures show that only a small share of BNPL loans end up with a late fee or get charged off as uncollectible, suggesting outright default on any single plan remains less common than the self-reported late-payment numbers might suggest.
That gap between a low default rate and a high rate of self reported late payments is the real story. People are not losing loans in large numbers. They are quietly absorbing fees and stress to avoid it, which never shows up in default statistics.
None of that means the tool is broken for everyone. For a single planned purchase, paid off on schedule, it works close to how it is advertised.
What shoppers can take from the newest data
The lesson here is less about any single loan and more about keeping count. A person who tracks one plan carefully can likely manage it the way the product was designed. The trouble starts when a second and third plan from different apps quietly layer on top without anyone adding them up.
That kind of quiet overcommitment is not unique to this habit. It echoes other everyday blind spots this desk has tracked, including unused loyalty points that pile up unnoticed because no single transaction feels worth tracking closely.
For now, the trend line is clear even if the full fallout is still being measured. Late payments are rising and simultaneous loans are common rather than rare.
Whether that trend keeps climbing or levels off will likely depend on how closely lenders start tracking what happens across apps, not just within one. Until then, the running total is still mostly up to the shopper to keep in their own head.
