Buy now, pay later splits a purchase into interest-free installments — typically four payments over six weeks — but it isn't a credit card with a different name. As of August 2026, the fine print, the dispute rights, and even federal oversight of these loans have all shifted, and most of the risk still lands on the shopper.
What Buy Now, Pay Later Actually Is
The mechanism is simple. A shopper checks out online or in-store, chooses a "pay in 4" or similar option, and the lender fronts the merchant the full amount. The buyer then repays the lender in a handful of fixed installments, most commonly four payments spread over about six weeks. The Consumer Financial Protection Bureau, in a market report published in December 2025, described the product as "typically a four-payment loan with no interest used by consumers to make retail purchases." No credit card is required, and many providers run only a soft credit check, which is part of the appeal — and part of the risk, since it's easy to open several of these loans at once without any single lender seeing the full picture.
What It Costs, in Real Numbers
The Bureau's report is built on data from six large providers — Affirm, Cash App Afterpay, Klarna, PayPal, Sezzle, and Zip — covering roughly 40% of the point-of-sale financing market. The figures below cover 2023, the most recent year in the report, checked as of the December 10, 2025 publication date.
| Metric | 2023 Figure |
|---|---|
| Average loan size | $135 |
| Loans per active user, per year | 6.3 |
| Average annual spending per user | $848 |
| Share of loans with a late fee | 4.1% |
| Average late fee, when charged | $9.99 |
| Charge-off rate | 1.83% of loans |
Paid on schedule, a BNPL loan usually costs nothing beyond the sticker price. The expense shows up when a payment is missed: fees are modest per instance, but a shopper juggling several loans at once can rack them up quickly, and a late payment can also trigger a credit-bureau report depending on the provider.
What Changed in the Oversight — and What Didn't
In May 2024, the CFPB issued an interpretive rule concluding that BNPL lenders function like credit card providers under existing law. It would have required them to investigate consumer disputes, suspend payment obligations while a dispute was pending, issue refunds to the account when merchandise was returned, and send periodic billing statements comparable to a credit card statement. The Bureau's own 2022 study, cited in that rule, found more than 13% of BNPL transactions among five surveyed firms involved a return or a dispute, worth about $1.8 billion in 2021 alone.
That rule never got the chance to bind the industry the way credit card rules do. On May 6, 2025, the CFPB announced it would not prioritize enforcement of the rule, saying it was keeping its resources "focused on pressing threats to consumers, particularly servicemen and veterans." On May 12, 2025, the Bureau formally withdrew the interpretive rule. The result: there is no standing federal requirement, as of this writing, that a BNPL lender handle a dispute or a refund the way Regulation Z requires a credit card issuer to. The Federal Trade Commission's consumer guidance, first published in December 2022 and last updated in May 2024, still tells shoppers plainly to check a provider's own policies on late fees, disputes, and returns before checkout, because those policies, not a uniform federal rule, are what currently govern the transaction.
How to Protect Yourself Before You Click "Pay in 4"
- Read the provider's own dispute and refund policy at checkout. It's the operative rulebook right now, not a card-style federal standard.
- Ask, or check the provider's disclosures, on whether it reports payment history to credit bureaus — a missed installment can still affect your score even on a product marketed as "no credit check."
- Budget for the whole schedule before you split anything. The CFPB's data shows the average user carries 6.3 of these loans a year and about $848 in annual BNPL spending — money that's easy to lose track of across several small installments.
- Keep the order confirmation and every payment receipt. If a dispute lands with the merchant rather than the lender, you'll want your own paper trail regardless of which company's policy applies.
FAQ
Does buy now, pay later charge interest? Most BNPL is structured as a four-payment plan with no interest if every installment is paid on time, per the CFPB's December 2025 report. The cost shows up in fees: in 2023, 4.1% of loans in the report were hit with a late fee, averaging $9.99 each.
What happens if I miss a payment? It depends on the provider. Expect a late fee, and check whether that provider reports payment history to credit bureaus — the FTC notes some do, which means a missed BNPL payment can affect your credit score the same way a missed card payment can.
Can I dispute a BNPL charge the way I would a credit card charge? Not automatically. A 2024 CFPB rule would have required BNPL lenders to investigate disputes and process refunds like card issuers, but the CFPB said in May 2025 it would not enforce that rule and later withdrew it. Dispute rights now depend on each lender's own policy, not a uniform federal standard.
Is BNPL regulated by the federal government at all? The CFPB still collects data on the sector — its December 2025 market report tracked six major providers — but it withdrew its main BNPL-specific consumer-protection rule earlier that year, so oversight currently runs through data-gathering rather than an enforced standard.
How much do people typically spend on BNPL loans in a year? The CFPB found the average user took out 6.3 loans in 2023 and spent $848 for the year, with a typical single loan around $135, across the six large providers the Bureau examined.
