Klarna has become one of the most widely used payment methods on Shopify UK due to its instalment options, high adoption among younger shoppers, and its ability to improve checkout conversion. However, Klarna also brings some of the highest payment processing fees in ecommerce. As competition increases and margins tighten, UK merchants need a way to reduce their dependency on expensive payment methods without harming conversion.
This guide explains how Klarna fees work, why they are so high, and how adding Pay-by-Bank can significantly reduce costs while maintaining a seamless customer experience.
Key Takeaways:
Klarna offers strong conversion benefits on Shopify UK, but it also carries some of the highest payment processing fees in the ecommerce sector.
Most merchants pay between 4.99% and 5.99% on Klarna instalment products, which can remove a significant portion of their margins.
Pay-by-Bank provides a low-cost alternative with typical fees between 0% and 1%, delivering 70–90% savings compared to Klarna.
Placing Pay-by-Bank first in the checkout flow reduces Klarna volume without harming conversions, while eliminating chargebacks entirely.
Combining Pay-by-Bank for everyday purchases and Klarna for instalments offers the best balance of cost efficiency and customer choice for Shopify UK merchants.

Longer settlement cycles
Did you know?
The result is improved conversion but significantly higher cost per transaction.
Klarna Fees Reduce Merchant Margins
Example: A £100 transaction using Klarna Pay in 3 incurs roughly £6.19 in fees.
For merchants with margins of 20 to 30 percent, Klarna can remove a large share of net profit. When Klarna accounts for 20 to 40 percent of checkout volume, total gateway costs rise substantially.
