Klarna vs Affirm Payments: Which BNPL Provider Is Better in 2026?

The global Buy Now, Pay Later (BNPL) market reached approximately $560 billion in gross merchandise volume in 2025, growing at a projected 20.7% CAGR. So it's no wonder why BNPL payment providers like Klarna and Affirm command significant attention in the industry.

Klarna and Affirm Payments are transforming the eCommerce landscape with a suite of features designed to meet the diverse needs of their customers. But the affirm vs klarna debate is more nuanced than it might first appear. Both platforms offer BNPL installments, but they differ significantly in fees, merchant reach, interest rates, and target markets.

That's the question we want to help you answer in today’s guide. We'll explore the strengths, benefits, and challenges of Klarna and Affirm, offering a clear comparison to help you decide which platform best fits your payment needs. Whether you're choosing klarna or affirm as a merchant, or affirm or klarna as a shopper, this guide covers everything you need to know.

Klarna Features and Overview at a Glance

Klarna is a leading Buy Now, Pay Later payment provider enabling consumers to purchase items from eCommerce and physical stores without paying the full amount upfront. Founded in Stockholm, Sweden, in 2005,  Klarna's growth spurt began with the streamlining of invoice payments for eCommerce customers. The reduced payment friction meant more sales and high conversions for the business.

But Klarna's rapid expansion came after the team introduced the BNPL model in the early 2000s, onboarding over 850,000 global merchant partners and ~114 million customers across 26 countries, with ~34 million based in the U.S. Klarna went public on the New York Stock Exchange in September 2025, the largest fintech IPO of the year, raising $1.37 billion and reaching a market valuation of over $17 billion on its first day of trading.

In March 2025, Klarna secured an exclusive partnership with Walmart through OnePay, a significant move that previously belonged to Affirm. Klarna reported $2.8 billion in revenue in 2024, with $105 billion in gross merchandise volume processed.

Klarna's BNPL model has proven especially beneficial to online retailers, reducing cart abandonment rates, which had plagued the industry due to complicated checkout processes. Klarna’s higher-converting checkout experience allows shoppers to pay for purchases in four interest-free installments every two weeks or settle the entire amount within 30 days. Klarna is said to process two million transactions daily, with big-name users including Nike, Adidas, H&M, and now Walmart.

How Does Klarna Work? Key Features

Klarna gives users a convenient payment process, whether they're purchasing from an eCommerce website, a mobile app, or a physical store. Understanding how Klarna works is straightforward: shoppers choose Klarna at checkout and select a repayment plan.

Klarna empowers users to avoid predatory debts by enabling them to track orders, payment programs, payment history, and access customer support all within the Klarna app. Notable Klarna features include the following:

• Pay in 4: Consumers can split purchases into four interest-free installments, with the payment due at checkout and the next three charged biweekly.
• Pay in 30: Customers can shop now and pay for transactions within 30 days if they are satisfied with their purchase.
• Long-term Loans: Klarna provides options to finance larger purchases over an extended period—typically ranging from 6 to 36 months, with competitive interest rates starting at 7.99%—through Klarna partner, WebBank.
• Klarna Card: Consumers can use a Klarna virtual card for installment payment and financing even if the store they're transacting with has yet to integrate the service. As of 2025, Klarna also launched a U.S. debit card pilot with FDIC-insured funds.
• KlarnaUSD Stablecoin: Launched in November 2025, Klarna released its own stablecoin on Stripe's blockchain to reduce costs on international payments.
• AI Shopping Assistant: Klarna has deployed an OpenAI-powered shopping assistant to help users manage spending and discover products.

For banks, fintechs, and merchants, Klarna's open banking makes finance "more accessible, fair, and simple for everyone." Klarna achieves this by enabling companies to leverage its connectivity to develop new products that benefit end users. Klarna says 15,000 partners are currently using its open banking API service. Half of the top 100 U.S. online retailers used Klarna's payment tools over the past year, and two-thirds ran advertising campaigns on its platform.

Their quick and easy integration allows merchants to enhance their stores by adding the option to pay later. You can choose the payment method that best suits your customers, craft a custom solution, or integrate through payment service providers on platforms like Shopify, WooCommerce, or Magento.

Klarna Fees: What Do Merchants Pay?

Klarna's business model is to charge merchants a flat fee per transaction and a percentage of sales, around 5% in the U.S. This is slightly higher than traditional card processors like Stripe or Shopify Payments charge. Understanding Klarna fees is important for merchants evaluating their margins. Klarna says its fees can also vary based on the country and which Klarna service the consumer chooses to use:

• Klarna Pay Later: Klarna's Pay Later option, which allows customers to settle their purchase within 14-30 days,  generally attracts transaction processing fees between 3.29% + $0.30 and 5.99% + $0.30 per transaction.
• Klarna Pay Now: Klarna's Pay Now option, offered through SOFORT, a notable bank transfer system available in Austria, Belgium, Germany, the Netherlands, and Spain, carries a transaction fee of ~2.99% + 40.30 per transaction.
• Klarna Financing: Klarna's extended financing option includes transaction fees ranging from 3.29% + $0.30 to 5.99% +$0.30.
• Klarna's Merchant Fees: While there are no setup fees, Klarna's merchant fees vary monthly based on the merchant's agreement and sales volume.
• Chargeback Fees: Klarna charges a ~$15 chargeback fee for every transaction dispute filed against you.

Buyers can also use the Klarna app at other retailers for a $2.12 service fee. There may be other costs, like currency conversion fees for international payments and integration fees. These costs vary based on the platform involved.

Klarna’s Advantages

Klarna has cemented its place as a leading BNPL payment provider in the U.S. and globally. Notable Klarna advantages include:

• Global availability with ~850,000 global merchant partners and ~114 million customers across 26 countries.
• Expedited checkout speeds shorten transaction times and cart abandonment rates, a perennial problem for eCommerce.
• Multiple repayment options are available; shoppers can choose from Pay in 4, Pay in 30, or longer-term financing plans.
• Zero interest rates on Pay in 4 or Pay in 30 plans foster customer loyalty, as satisfied customers who can spread out their purchases are more likely to return.
• Klarna protects merchants from the financial impacts of non-paying customers by assuming the risks linked to its financing.
• Klarna is easy to set up and user-friendly, integrating with major eCommerce platforms for quick payment acceptance.
• The advanced Klarna fraud prevention measures reduce financial losses.
• Soft credit checks with high approval odds unlock revenues for businesses.
• Klarna went public in September 2025, adding institutional transparency and credibility for merchants evaluating long-term platform risk.

Klarna’s Disadvantages

Every platform has downsides you should look into for informed decision-making. For Klarna, the reported downsides include:

• Klarna charges businesses a transaction fee, which is a percentage of the total transaction amount.
• Consumers who miss repayment deadlines incur a $7 fee after 10 days. However, Klarna ensures the total late fees for an order will not exceed 25% of the total purchase amount. Affirm has called attention to these as "junk fees",  a point worth noting when comparing klarna vs affirm.
• Defaulting on repayment may result in a shopper being handed over to a collection agency and reported to the credit bureau, negatively affecting a person's credit score.
• Analysts have argued that since BNPL services use internal algorithms instead of traditional credit checks, the system can be vulnerable to fraud.

Affirm Overview and Features at a Glance

Affirm is another household name in the buy now, pay later financing vertical. PayPal co-founder, Max Levchin, founded the payment network in 2012. The company went public on Nasdaq in January 2021 and has a market capitalization exceeding $28 billion as of early 2026, nearly double Klarna's IPO valuation.

Affirm delivered 46% revenue growth in 2024, reaching $2.32 billion, the fastest growth of any major BNPL provider that year, and crossed into profitability with a net profit of $52 million in fiscal year 2025.

Affirm wants to be a healthy alternative to credit cards. Affirm loans come with a fixed payment plan, and shoppers know their options before finalizing each transaction. That way, they never pay more than the agreed amount. Users can transact online or with the Affirm app at participating retailers, which can create virtual card numbers for purchases at any Visa-accepting store. Additionally, Affirm customers can select payment plans of up to 48 months, which is more flexible than traditional Pay in 4 options used by competitors like Klarna.

When you create an Affirm account, they appraise and assign you a custom spending limit. While the spending limit varies for everyone, a shopper's spending limit with Affirm cannot exceed $17,500.

Affirm now has approximately 23 million active users and 377,000 merchant partners, with deep integrations at Amazon, Shopify, and, until March 2025, Walmart.

Affirm Key Features

Affirm is for purchase financing with partner merchants. Unlike some platforms that provide short-term loans alongside bill payment or money transfer services, Affirm focuses solely on shopping financing. Notable Affirm features include the following:

• No Fees: Shoppers pay no late repayment fees, prepayment fees, annual fees, or charges for account opening/closing fees.
• Pay in 4: Affirm's "Pay in 4" option lets you pay in four equal installments over six weeks, with zero interest or fees for purchases between $50 and $1,000.
• Affirm Card: Shoppers can use Affirm debit cards for full payments like traditional payment cards or flexible plans via the app.
• Monthly Financing: Affirm allows shoppers to finance purchases up to $17,500, with repayment terms ranging from 3 to 48 months at ~30% Annual Percentage Rate (APR). This depends on how much risk you pose and the retailer involved.

Affirm typically allows merchants to determine credit limits for their shoppers, with a maximum threshold of $17,500. They’ve partnered with thousands of retailers across categories like apparel, travel, electronics, home, and fitness. You can shop using Affirm online or with the mobile app, and for in-store purchases, you can use the virtual card.

How Much Does Affirm Charge Merchants?

Affirm does not charge any fees to shoppers. So how much does Affirm charge merchants? The BNPL provider charges a percentage of each transaction. Here's the breakdown:

Affirm provides custom plans with tailored solutions to larger enterprises at a different fee structure. Other fees include interchange fees and loan servicing fees charged to third-party investors.

Affirm’s Advantages

Affirm offers rates as low as 0% for terms of up to 48 months. Integrating it into your store is particularly advantageous to sellers of high-ticket items priced over $500 and those targeting Gen Z shoppers, who spend under $100. Notable Affirm advantages include:

• Getting started is effortless; the registration process requires minimal steps and details.  
• Affirm performs a soft credit assessment on shoppers to determine creditworthiness without intruding on their credit scores.
• Buyers can split costs into four interest-free biweekly payments, with the first installment due at purchase, or choose extended repayment over three or more months –meaning high conversion for merchants.

• Shoppers do not pay any fees for late repayments, prepayment, account opening, or closure. This is a key differentiator in the affirm vs klarna fee debate.

• The platform has positive ratings and integrates with major stores, including Amazon and Shopify.
