Affirm review for 2026: how the buy now pay later leader works for shoppers and merchants, its fees, APR ranges, and how it compares to Klarna and Afterpay.
Affirm is a buy now pay later (BNPL) fintech company founded in 2012 by Max Levchin, the PayPal co-founder, along with Nathan Gettings, Jeffrey Kaditz, and Alex Rampell. Headquartered in San Francisco, the company lets online and in-store shoppers split purchases into installment payments at checkout instead of paying the full amount upfront or opening a traditional credit card.
Affirm went public on Nasdaq (ticker AFRM) on January 13, 2021, raising approximately 1.2 billion dollars in its IPO. It is one of the largest publicly traded BNPL companies, reporting tens of millions of active consumers and hundreds of thousands of active merchants as of 2026, with tens of billions of dollars processed annually.
Affirm's headline products are Pay in 4, which splits a purchase into four interest-free biweekly payments, and longer monthly installment loans that stretch from about three to sixty months with APRs ranging from 0 percent to 36 percent depending on the purchase and the borrower's approval terms.
Affirm does not act as a direct lender; instead it partners with issuing banks like Cross River Bank, Evolve Bank and Trust, and Celtic Bank to originate loans, and it uses machine learning underwriting to approve or decline transactions instantly. Shoppers can use Affirm at directly integrated merchants (Shopify, Amazon, Walmart historically, and thousands of other stores) or via a virtual card at retailers without a native integration. The Affirm Card extends the model to everyday debit spending with optional pay-over-time.
For consumers, Affirm charges no application fees, no late fees, and no compounding interest; the total repayment amount is shown before the purchase is confirmed, and interest, where charged, ranges from 0 percent to 36 percent APR depending on the loan.
For merchants, Affirm charges a transaction fee that can reach roughly 12.5 percent of the purchase amount in exchange for higher checkout conversion, larger average order values, and instant upfront payment, since Affirm pays the merchant in full at the time of sale and assumes the repayment risk.
No. Affirm partners with issuing banks such as Cross River Bank, Evolve Bank and Trust, and Celtic Bank to originate its loans.
No, Affirm does not charge late fees, though missed payments can still be reported and affect a borrower's credit.

Max Levchin, the PayPal co-founder, founded Affirm in 2012 along with Nathan Gettings, Jeffrey Kaditz, and Alex Rampell.
Affirm earns revenue from merchant transaction fees and from interest charged to consumers on interest-bearing installment loans.
Affirm leans more heavily on longer-term, sometimes interest-bearing installment loans, while Klarna and Afterpay have historically emphasized short, interest-free four-payment plans, though all three now offer overlapping products.
It can. Longer-term Affirm loans may involve a credit check, and payment history can be reported to credit bureaus, which can help or hurt a score depending on repayment behavior.
