How does buy now, pay later (BNPL) work, and how does it compare to credit cards?
BNPL splits a purchase into a short installment schedule — typically four equal payments over six weeks, interest-free if you pay on time. Unlike credit cards, it's not revolving credit: each loan is a discrete, closed-end transaction. The convenience is real, but the dispute protections and credit-bureau reporting are weaker and less consistent than with cards.
BNPL, offered at checkout by providers like Affirm, Klarna, Afterpay, and PayPal, lets you pay in installments with no interest if every payment is on time (longer-term plans of 3-36 months do charge interest and behave more like an installment loan). The core differences from a credit card: a card is revolving — you can carry a balance, pay the minimum, and reuse the line — while a BNPL loan is closed-end, a single transaction with a fixed schedule. Standard pay-in-4 charges no interest if you're on time; a card charges 20-30% APR on any carried balance. Dispute rights also differ: cards carry Fair Credit Billing Act protections if a merchant fails to deliver, whereas BNPL dispute rights depend on the provider's own policies. The CFPB has flagged that gap, along with inconsistent bureau reporting and a tendency to encourage spending beyond budget.
