Affirm is a shopping and financial app that lets users buy now and pay over time through installment plans at participating online and in-store retailers. Instead of paying the full price upfront, shoppers split a purchase into scheduled payments, with terms presented before they commit. Affirm shows the total cost and any interest clearly, and many purchases qualify for plans with no late fees. The app includes a virtual card for use at additional stores, tools to track upcoming payments, and a marketplace for discovering brands that accept Affirm. It is aimed at shoppers who want flexible, transparent payment options for larger purchases and prefer predictable installments over traditional revolving credit card debt.

Affirm is one of the more transparent players in the buy-now-pay-later space, and that transparency is its biggest strength. Before you commit, the app clearly states the number of payments, the amount of each, and the total cost including any interest, which compares favorably to the opaque revolving balances of many credit cards. The virtual card extends its usefulness to retailers that do not natively support Affirm, and payment tracking helps users stay organized. The honest considerations are significant, though. Affirm is still a form of borrowing, some plans carry interest depending on the merchant and your approval terms, and the convenience of splitting payments can encourage overspending on purchases you might otherwise skip. Approval and rates vary by individual, and missed payments can affect your standing. Used deliberately for planned, larger purchases, Affirm is a clear, flexible tool; used impulsively, it carries the same risks as any credit.
