Buy now, pay later looks harmless at checkout: four payments, no interest, no credit application. The risks of buy now, pay later for Gen Z sit further downstream — overdraft fees when auto-debits bounce, multiple loans running at once across different apps, weakened dispute rights compared to a credit card, and collections activity that can damage credit when payments slip. About two-thirds of Gen Z consumers have used a BNPL service, the highest adoption rate of any generation, and roughly 39% of Gen Z users report having made at least one late payment.
How the Payments Actually Work
The most common BNPL product is a pay-in-4 plan. You pay about 25% at checkout, then three more installments hit your account every two weeks for the next six weeks. The short-term plans are typically interest-free. Payments come out automatically from a linked debit card or bank account, not a credit card you actively pay each month.1Consumer Financial Protection Bureau. What Is a Buy Now, Pay Later (BNPL) Loan?
That auto-debit setup is the piece most new users underestimate. You don’t get a bill and choose when to pay it. The BNPL provider pulls the money on a set date, and if the money isn’t there, problems compound quickly.
Longer-term BNPL installment loans exist too, usually for bigger purchases spread over months or years. Those often charge interest and function more like traditional financing. Read the terms before accepting; “buy now, pay later” covers both categories.
Why the Loans Pile Up
Opening a BNPL account is almost frictionless. No hard credit check, instant approval at checkout, minimal income verification. That’s the design, and it’s also why balances multiply. CFPB research found that roughly 63% of BNPL borrowers had multiple simultaneous loans at some point during a given year, and about a third were borrowing from more than one BNPL lender at the same time.2Consumer Financial Protection Bureau. CFPB Research Reveals Heavy Buy Now, Pay Later Use Among Borrowers With High Credit Balances and Multiple Pay-in-Four Loans
Younger users carry a disproportionate share. Among BNPL borrowers aged 18–24, these loans represented 28% of their total unsecured consumer debt, compared with 17% across all age groups.2Consumer Financial Protection Bureau. CFPB Research Reveals Heavy Buy Now, Pay Later Use Among Borrowers With High Credit Balances and Multiple Pay-in-Four Loans Nearly 40% of Gen Z users make BNPL purchases weekly, and the average BNPL borrower took out 6.3 loans per lender in 2023, an 11% increase over the previous year.3Consumer Financial Protection Bureau. Buy Now, Pay Later Market Trends and Consumer Impacts
The category mix has shifted too. Clothing is still the top BNPL purchase, but roughly a quarter of BNPL users now finance grocery orders, about double the rate from two years earlier. Food delivery, event tickets, and personal care items have all become routine BNPL transactions. When a $40 grocery run gets split into four payments, the tool is doing something different than covering an occasional big purchase.
The CFPB also found that credit card utilization rates were already rising for consumers before their first BNPL loan. In other words, BNPL often shows up when existing credit is already stretched, and it stacks on top rather than replacing anything.
Late Fees Plus Overdraft Fees
Pay-in-4 plans are marketed as interest-free, and they usually are. Interest-free is not fee-free. Most BNPL lenders charge a late fee when a scheduled payment misses, averaging about $10 per incident across major providers.4Consumer Financial Protection Bureau. Do Buy Now, Pay Later (BNPL) Loans Have Fees? On a small loan, that’s a meaningful percentage. Policies vary: Affirm charges no late fees on any of its products, while others cap fees at a percentage of the missed installment or a flat dollar amount. The terms are in the loan agreement you accept at checkout.
The bigger problem is the second layer of fees. Because BNPL payments auto-debit, a failed payment can trigger overdraft or non-sufficient-funds fees from your bank at the same time the BNPL provider charges its own late fee. Federal banking regulators have flagged this specific combination — automatic withdrawals on short payment intervals — as a distinctive risk of the BNPL model.5Office of the Comptroller of the Currency. Retail Lending: Risk Management of Buy Now, Pay Later Lending A $35 overdraft fee on a $32 installment isn’t unusual, and neither is having two or three of those bounce in a single week if you have multiple BNPL plans running.
What Happens If You Default
Missed payments trigger a predictable sequence. First the account freezes, cutting off any new BNPL purchases. If the balance stays delinquent long enough, the provider charges off the debt and sells it to a third-party collector. About 1.8% of all BNPL loans ended in charge-off in 2023.3Consumer Financial Protection Bureau. Buy Now, Pay Later Market Trends and Consumer Impacts
Once a debt reaches a collector, it’s likely to appear on your credit report as a collection account, which will significantly damage your credit score.6Consumer Financial Protection Bureau. What Happens if I Can’t Pay Back a Buy Now, Pay Later (BNPL) Loan? This is where the asymmetry of BNPL credit reporting bites hardest: on-time payments often build nothing, while a serious delinquency can still hurt you.
Whether BNPL Builds or Hurts Your Credit
Credit reporting depends entirely on which provider you use. Historically, most BNPL transactions were invisible to the major bureaus. On-time payments did nothing for your credit history, but a default that reached collections could still land on your report and drag your score down.
Affirm broke from that pattern in 2025, reporting all pay-over-time products, including pay-in-4 loans, to both Experian and TransUnion.7Affirm Holdings, Inc. Affirm Expands Credit Reporting With TransUnion to All Pay-Over-Time Products8Experian. Affirm Expands Credit Reporting With Experian to Include All Pay-Over-Time Products If you use Affirm and pay on time, that history now goes on your credit file.
Klarna and Afterpay have not followed. Klarna reports its longer-term interest-bearing loans but keeps pay-in-4 activity off the bureaus, and Afterpay has said it won’t change course without evidence that reporting would help rather than hurt borrowers. Before you use a provider expecting the on-time payments to help your credit, check that specific provider’s reporting policy — assumptions here will be wrong more often than right.
BNPL applications themselves almost always involve a soft credit check, which does not affect your credit score. Hard inquiries are reserved for larger, longer-term installment products.9Consumer Financial Protection Bureau. Will a Buy Now, Pay Later (BNPL) Loan Impact My Credit Scores?
Weaker Dispute Rights Than a Credit Card
In 2024, the CFPB issued an interpretive rule classifying BNPL lenders as credit card issuers under the Truth in Lending Act. Under that rule, BNPL companies would have had to investigate billing disputes, pause payments during investigations, and issue refunds when consumers returned products.10Consumer Financial Protection Bureau. CFPB Takes Action to Ensure Consumers Can Dispute Charges and Obtain Refunds on Buy Now, Pay Later Loans
That rule is no longer in effect. The CFPB determined the rule was “procedurally defective” and said it is “contemplating taking appropriate action to rescind” it entirely.11Consumer Financial Protection Bureau. CFPB Announcement Regarding Enforcement Actions Related to Buy Now, Pay Later Loans BNPL users currently cannot count on the same federal dispute and refund rights that credit card holders have.
Some Regulation Z billing-error protections still exist for items never delivered, delivered to the wrong address, or that don’t match what was ordered. To invoke them, written notice has to reach the creditor within 60 days of the statement containing the error, and quality complaints about goods you already accepted are not covered.12Consumer Financial Protection Bureau. Regulation Z – Billing Error Resolution Whether any given BNPL provider is subject to those rules right now is legally uncertain. In practice, your refund and dispute rights depend heavily on the provider’s own policy. Read it before you buy, not after something goes wrong.
Returns While Payments Keep Debiting
Returns are where BNPL gets awkward. When you return something bought on a credit card, the refund goes back to the card and the transaction closes. With BNPL, the refund has to route back through the provider, and scheduled installments may keep auto-debiting from your bank account while the return is being processed.
Handling varies by provider. Some pause the payment schedule once the merchant confirms the return; others require you to keep paying until the refund clears. A partial refund may still leave you owing part of the loan balance. Refund processing through the BNPL provider is often slower than a credit card refund, sometimes two to four weeks after the merchant processes their side.
Contact both the retailer and the BNPL provider before shipping a return. Save tracking numbers and screenshots. If payments continue after a return is confirmed, dispute the charges in writing with the provider.
If BNPL Debt Becomes Unmanageable
BNPL debt is treated like credit card debt in bankruptcy: general unsecured debt with no collateral. In Chapter 7, BNPL balances are eligible for discharge. In Chapter 13, they go into the unsecured creditor pool and typically get paid pennies on the dollar over a three-to-five-year plan. Filing also triggers an automatic stay that stops collection calls, lawsuits, and wage garnishments from the providers and any collectors who bought the accounts.
There is one carve-out to know about. If BNPL purchases of luxury goods from a single creditor exceed $900 within 90 days before filing, the law presumes the debtor didn’t intend to repay, and a creditor or trustee can challenge discharge of those specific debts.13Office of the Law Revision Counsel. 11 U.S. Code 523 – Exceptions to Discharge Necessities like groceries and basic clothing don’t fall under this rule; it targets discretionary spending that looks like loading up right before a filing.
One practical wrinkle: the legal lender of record on a BNPL loan is often a partner bank rather than the brand name on the app. When listing creditors in a filing, check the loan agreements rather than the app interface.
