Klarna Economics: Is the 5.99% Merchant Fee Worth It? (United Kingdom)

While standard credit cards cost 2.9% + 30¢, Klarna's higher 5.99% fee is an investment in consumer purchasing power.

AOV Expansion

Consumers spend up to 41% more per order when paying in 4 installments instead of upfront with a debit card.

Zero Non-Payment Risk

Klarna pays you the full amount upfront. If the buyer defaults on subsequent bi-weekly payments, Klarna absorbs the entire loss.
