13 Buy Now, Pay Later Apps Compared: Fees, Terms and Best Uses

Buy now, pay later (BNPL) apps split a purchase into smaller payments, usually four payments over six weeks or monthly installments for bigger buys. For most US shoppers, PayPal Pay in 4 and Afterpay are the cheapest choices for small purchases because they charge no interest and PayPal charges no late fees, while Affirm, Klarna and PayPal Pay Monthly cover larger purchases at up to about 36% APR. Zip and Sezzle now charge fees on many Pay in 4 loans, so compare the total cost at checkout.

What Is Buy Now, Pay Later (BNPL)?

A BNPL loan splits a purchase into installments. Pay in 4 plans take the first payment at checkout and the rest every two weeks. Monthly plans run from 3 to 24 months or longer and can charge interest. Approval is usually decided purchase by purchase, so the amount you can spend changes from one order to the next.

Compared with a credit card, a Pay in 4 plan paid on time costs nothing extra, while a card balance carried past the due date builds interest. The catch is that missed BNPL payments can bring late fees, and several open plans are easy to lose track of. Some card issuers now offer their own installment plans, covered at the end of this list.
