BNPL (Buy Now, Pay Later)

Also known as: Buy Now Pay Later, Pay in 4

Point-of-sale installment financing splitting a purchase into 3-4 interest-free payments over 6-8 weeks. Major US providers (Affirm, Klarna, Afterpay, PayPal Pay in 4) extend credit at checkout via soft pull approval.

Buy Now, Pay Later is a US payments category that grew rapidly after 2020 as a checkout-time alternative to credit cards. The standard structure: the BNPL provider pays the merchant in full at the time of purchase, then collects four equal installments from the consumer over six to eight weeks (typically 25% at checkout plus three additional 25% payments on bi-weekly cycles). The consumer pays no interest if all installments are paid on time. The provider's revenue comes from merchant fees (typically 2-6% of the transaction, higher than credit card interchange) and from late fees and interest on delinquent accounts. For consumers, the interest-free structure can be a useful tool for spreading a $200 to $1,500 purchase over two months.

Major US BNPL providers in 2026 include Affirm (which also offers longer-term installment loans with disclosed APR), Klarna, Afterpay (owned by Block), and PayPal Pay in 4 (integrated into PayPal checkout); Apple discontinued its own Apple Pay Later product in June 2024 and now routes Apple Pay installments through Affirm and card issuers. Each provider has its own underwriting (typically soft credit pull at application), credit limits (initial $200-$1,000, growing with payment history), and payment scheduling. Credit decisions and payment records have historically not been reported to credit bureaus systematically, though Equifax began accepting BNPL data in 2022, Affirm started reporting all of its loans to Experian and TransUnion in 2025, and FICO released BNPL-aware score versions (FICO Score 10 BNPL and 10T BNPL) the same year.

The CFPB's regulatory posture on BNPL tightened through 2024 and then reversed. A May 2024 interpretive rule classified BNPL providers as credit card issuers under the Truth in Lending Act, with dispute rights and refund processing analogous to credit card chargebacks; on May 12, 2025 the Bureau withdrew that rule and later said it would not reissue it, so at the federal level pay-in-four loans are again outside the credit card protections. Some states — New York, with the licensing regime it enacted in 2025, among them — have moved to regulate BNPL lenders on their own, which is where new consumer rules are now most likely to come from.

BNPL has structural risks for consumers using it as recurring revolving credit rather than for occasional spreading of large purchases. Stacking multiple concurrent BNPL plans across providers can produce a hidden total monthly obligation exceeding the consumer's actual repayment capacity. Late payments trigger fees that frequently exceed credit card late fees in proportional terms — a $35 late fee on a $200 payment is 17.5% of the installment. The non-uniform credit reporting makes the obligations invisible to standard underwriting, meaning a household with $2,000 of stacked BNPL plus a mortgage application can be approved at terms that do not reflect the actual total debt load.
