Quick Reference & Frequently Asked Questions
How much does Klarna, Affirm, or Afterpay actually charge e-commerce merchants?
While standard credit card processors like Stripe or Shopify Payments charge roughly 2.9% + $0.30, Buy Now Pay Later (BNPL) providers typically charge merchants 4.99% to 5.99% + $0.30 for Pay-in-4 orders, and 6.50% to 8.99%+ when offering 6-to-12-month 0% APR financing to shoppers.
How much AOV lift do I need for Buy Now Pay Later to be profitable?
It depends on your gross margin. If your store has a 36% gross margin and switches an order from a 2.9% card to a 5.99% BNPL plan, the extra 3.09% fee spread consumes nearly 10% of your contribution margin—meaning you need at least a 10%–14% increase in Average Order Value (or incremental conversion) just to break even.
What happens to BNPL merchant fees when a customer returns an order?
Most BNPL gateways retain their merchant discount rate (MDR) and fixed transaction fee even when a shopper returns the merchandise for a full refund. On a $200 order at 5.99% + $0.30, a return costs you $12.28 in non-refundable payment fees before counting return shipping.
Why should merchants set a minimum cart threshold for BNPL checkout options?
Shoppers buying a $40–$65 item rarely need 4-part financing and will happily pay with Apple Pay or a debit card. Hiding BNPL below a calculated cart threshold (e.g., $110+) stops existing customers from cannibalizing your margin with 6% processing fees.
