How Does Klarna Make Money? Business Model, Revenue Streams and Fees

Key Takeaways

• Much of Klarna’s income starts with merchants paying for payment processing, flexible payment options, settlement, and related services when shoppers transact through the Klarna network.
• Interest-free does not mean revenue-free: a shopper can pay 0% interest while the merchant still pays Klarna under its commercial agreement.
• Longer-term financing, consumer fees and subscriptions, card economics, advertising, and gains on some consumer-receivable sales diversify the business beyond classic BNPL commissions.
• Klarna reported $1.042 billion in Q2 2026 revenue, $27 million in operating income, and $9 million in net income.
• The economics of each transaction depend on payment type, market, merchant pricing, funding costs, servicing costs, and credit risk.

How does Klarna make money? The short answer is that the shopper does not always have to pay Klarna for Klarna to earn money.

That can seem counterintuitive because Klarna is best known for letting customers split purchases into interest-free installments. But Klarna is not simply handing out free credit. It operates a wider payments, financing, banking, card, advertising, and commerce network connecting consumers with merchants.

A retailer can pay Klarna when a shopper uses an eligible payment method. Customers using longer-term financing may pay interest. Klarna can also earn money from consumer services, memberships, cards, advertising, and financial activities such as selling selected receivables.

The scale is significant. In Q2 2026, Klarna reported more than 120 million active consumers, more than 1.2 million merchants, $36.6 billion in gross merchandise volume (GMV), and $1.042 billion in quarterly revenue.

So, rather than thinking of Klarna as only a “buy now, pay later” company, it is more useful to understand the different parts of its ecosystem and how each one can produce income.

The Klarna Company Story

Klarna’s official company history traces the business back to Stockholm in 2005. The company began as Kreditor, changed its name to Klarna in 2010, passed a $1 billion valuation milestone in 2012, acquired SOFORT in 2014, obtained a banking license in 2017, and launched the Klarna app in 2018. Earlier business-model profiles also show how the company evolved from an ecommerce payments idea into a much broader fintech platform.

A major corporate milestone came on September 10, 2025, when Klarna listed on the New York Stock Exchange under the ticker KLAR. That public-market status matters when reading older articles about Klarna’s private valuation or funding rounds: those figures now describe its history, not its current market value.

Klarna: Facts & Statistics

These figures use Klarna’s current investor reporting rather than older statistics that still circulate in third-party articles. For a broader third-party overview of Klarna and BNPL mechanics, see this TechBuilder explainer.

What Does the Company Klarna Do?

Klarna is a global digital bank and flexible-payments provider. For ecommerce shoppers, it is most visible at checkout, where the available payment choices depend on the merchant, market, purchase, and customer eligibility.

Those choices can include:

• Paying for a purchase immediately.
• Paying after a short delay, such as Pay in 30 days where available.
• Splitting a purchase into interest-free installments, such as Pay in 4.
• Financing a purchase over a longer term with monthly payments.
• Paying through Klarna’s card, app, or other supported wallet integrations.

In the U.S., for example, Klarna’s Pay in 4 divides an eligible purchase into four interest-free payments, with the remaining payments generally collected every two weeks. Klarna says there are no fees when the shopper pays on time.

The merchant-side experience is different. Instead of building its own installment underwriting, collection, settlement, and payment infrastructure, a retailer can integrate Klarna and operate under a commercial agreement with it. Klarna then manages the consumer-side payment relationship and the economics around that transaction.

What Is Buy Now, Pay Later (BNPL)?

Buy Now, Pay Later (BNPL) is a payment approach that lets a shopper receive or order a product now and pay for it later, either in several installments or after a short delay. Some BNPL products are interest-free when the payment schedule is followed; others are longer-term financing products that can charge interest.

A typical BNPL purchase works in a few simple steps:

1. The shopper adds products to a cart online or chooses them in a physical store.

2. At checkout, the shopper selects Klarna or another BNPL option.

3. The provider assesses eligibility for the available payment options.

4. The shopper chooses a repayment plan, such as Pay in 4, Pay in 30 days, or longer-term financing.

5. The merchant receives settlement according to its agreement with the provider, while the provider manages the consumer repayment schedule.

6. The shopper pays the remaining balance according to the selected plan, often through automatic payments or the provider’s app.

Why Is Buy Now, Pay Later Popular?

BNPL has become popular because it changes when and how shoppers pay without requiring merchants to build a financing operation themselves.

• Lower upfront payment can make a purchase easier to fit into short-term cash flow.

• Fixed installment schedules can feel easier to understand than open-ended revolving balances.

• Some short-term plans charge no interest when paid as agreed.

• The option appears directly in the checkout flow, so shoppers do not need a separate traditional loan process.

• Merchants can offer more payment choice without collecting installments themselves.

• Apps, reminders, and automatic payments make repayment easier to manage.

The Klarna Business Model in Simple Terms

The Klarna business model connects two major groups: consumers who want convenient ways to shop and pay, and merchants that want to convert sales while outsourcing much of the complexity behind flexible payments.

Benefits of Klarna for Consumers

• More ways to pay at checkout.
• Interest-free short-term options on eligible purchases when paid on time.
• Smaller scheduled payments instead of one larger upfront payment.
• A single app for payments, shopping tools, reminders, and eligible card features.
• The ability to choose longer financing for some larger purchases when approved.

Benefits of Klarna for Retailers

• Flexible payment options without building a lending and collection system in-house.
• Merchant settlement handled under the Klarna commercial agreement.
• Klarna manages the consumer repayment relationship for eligible products.
• A broader set of payment choices can reduce checkout friction for some shoppers.
• Access to Klarna’s wider shopping, advertising, card, and discovery ecosystem.

Klarna sits between the consumer and the merchant. When a transaction takes place through its network, Klarna can earn merchant-related revenue while taking responsibility for parts of the payment process. It can then earn additional revenue through consumer services, interest, advertising, cards, and other financial activities.

Klarna’s audited 2025 annual report shows how diversified that model has become:

According to the same 2025 annual report, revenue increased 25% from $2.811 billion in 2024 to $3.509 billion in 2025, while GMV reached about $128 billion. Merchant transactions remain fundamental, but the company is clearly not dependent on one BNPL commission.

How Does Klarna Make Money? The Main Klarna Revenue Streams

The easiest way to understand the Klarna revenue streams is to separate the main ways money enters the business. Some third-party breakdowns, including Nimble AppGenie’s Klarna revenue-model guide, focus heavily on merchant commissions, interest, late fees, advertising, and cards. Klarna’s audited reporting gives a more precise picture of how those items are classified.

1. Merchant and Transaction Fees

Merchant payments are at the heart of the model. When a shopper uses an eligible Klarna payment method, the retailer pays according to its commercial agreement.

Klarna’s 2025 filing explains that merchant revenue primarily consists of fees paid by merchants when consumers transact on its network. It also includes interchange revenue and certain dispute-settlement fees. Current Klarna pricing documentation shows that transaction pricing can contain both a fixed fee and a variable percentage fee.

There is an important detail: Klarna does not publish one universal merchant rate that applies to every business. Current pricing documentation says effective rates can depend on the price plan, payment program, customer and partner country, merchant category, sales channel, discounts, and other contractual terms.

Older third-party fee guides sometimes quote figures such as a $0.30 fixed fee plus a percentage in the 3.29%–5.99% range, depending on the product. Those figures are useful only as historical or illustrative references, not as a universal current Klarna price. Merchants should rely on their own current price plan and contract. See the third-party fee example and Klarna’s settlement fee definitions for the distinction.

Simple example: suppose a merchant’s own contract charged a hypothetical 4.00% plus $0.30 on a $200 capture. The fee would be $8.30, leaving $191.70 before any other adjustments. That is only an example of how fixed-plus-percentage pricing works; it is not a quoted Klarna rate.

For a retailer, this is not simply a “loan fee.” The merchant is paying for payment infrastructure, settlement, payment flexibility, and related services surrounding the transaction.

2. Interest From Longer-Term Financing

Not every Klarna payment product is interest-free. Short-term options such as standard Pay in 4—and Pay in 30 days where available—can be interest-free when the customer follows the applicable terms. Longer-term financing works differently.

In the U.S., Klarna’s current financing disclosures show APRs ranging from 0.00% to 35.99%, depending on creditworthiness, term length, approval, and the specific offer. Klarna’s consumer pages currently advertise pay-over-time terms that can extend across several months, with exact options depending on the purchase and approval.

For example, a shopper buying a more expensive laptop or sofa may choose monthly financing instead of paying the full amount at checkout. The shopper repays principal over time and, when an interest-bearing offer applies, Klarna earns interest on the outstanding balance.

This was a major revenue source in 2025. Klarna reported $937 million in interest income, up from $675 million in 2024. Of the 2025 total, $617 million came from Fair Financing. The same interest-income category also included $161 million of “Snooze” fees, $134 million of interest from debt securities, and $25 million of incremental merchant fees related to certain promotional financing arrangements.

That last point is why “interest on cash” is too vague. Klarna’s audited reporting specifically identifies interest from debt securities, rather than describing the income simply as interest earned on idle cash.

3. Late, Reminder, and Other Consumer Fees

Klarna can also earn money from consumer fees, but the type and amount depend on the product and market. For U.S. Pay in 4, Klarna says that if a payment remains unsuccessful after another collection attempt, a late fee of up to $7 may be added. Aggregate late fees on the order will not exceed 25% of the order value.

It is important not to treat every consumer-fee line in Klarna’s financial statements as a U.S. Pay in 4 late fee. The 2025 consumer service revenue category included administrative and reminder fees across the business, as well as other consumer services and subscription revenue.

Older late-fee tables in third-party Klarna articles can become outdated, so consumer-facing fee language should always be checked against the current Klarna product page for the relevant market.

4. Memberships and Other Consumer Services

Some income comes directly from consumers without taking the form of traditional loan interest. Klarna reported $397 million of consumer service revenue in 2025. That category included reminder and administrative fees, fees for certain consumer services, and subscription income.

Memberships are becoming more important. In Q2 2026, Klarna said it had reached 2 million paying membership subscribers—about eight times the number a year earlier—and that subscription revenue had grown by more than 600%.

This gives Klarna a recurring consumer relationship that does not depend entirely on an individual BNPL checkout transaction.

5. Card and Interchange Economics

Klarna is also expanding beyond the checkout button. Its card products let consumers use Klarna across a wider range of purchases, which creates more transaction volume and can generate interchange-related economics.

Klarna reported 6.5 million active Klarna Card users across 16 countries in Q2 2026, up from 1.3 million a year earlier. Card-related fees and interchange are included within Klarna’s broader transaction and service revenue rather than reported as a completely separate top-level revenue category.

Strategically, the card gives Klarna more opportunities to participate in everyday spending instead of waiting for a shopper to encounter a Klarna button at a partner checkout.

6. Advertising and Shopping Discovery

Klarna increasingly acts as a shopping-discovery platform as well as a payment provider. Its app and network can connect shoppers with products and merchants through search, offers, recommendations, affiliate links, sponsored placements, and brand advertising.

Klarna’s 2025 annual report states that advertising revenue includes sponsored search, affiliate programs, and brand advertisements. Advertising revenue was approximately $190 million in 2025, up from $180 million in 2024.

That means Klarna can monetize shopping intent before or alongside a payment transaction. For ecommerce brands, the platform can therefore function as both a payment channel and a potential customer-acquisition channel.

7. Sales of Certain Consumer Receivables

A less obvious source of income comes from selected consumer receivables created when Klarna finances purchases. Klarna does not necessarily keep every qualifying receivable on its own balance sheet until final repayment.

In 2025, Klarna reported a $73 million gain from sales of consumer receivables. In Q2 2026, it reported another $69 million of gain on sale of consumer receivables for the quarter.

Selling qualifying receivables can diversify funding sources and reduce the amount of capital tied up in loans the company originated. Klarna can also continue servicing some sold receivables for a fee under certain arrangements.

How Does Klarna Make Money Without Interest?

So, how does Klarna make money without interest? The clearest answer is that the merchant can pay Klarna even when the shopper does not pay interest.

Imagine a simplified $200 ecommerce purchase. The customer chooses an interest-free installment option and still repays a total of $200. Klarna settles with the merchant according to the commercial terms agreed between the two businesses, which may include merchant fees.

The phrase “interest-free” describes the shopper’s financing terms. It does not mean Klarna provides the merchant’s payment infrastructure, settlement, risk management, or commerce services for free.

Klarna can also earn from that consumer relationship later through card use, memberships, advertising, other purchases, or other services, but merchant-paid transaction economics provide the simplest explanation for how the model can work without consumer interest.

How Does Klarna Make Money on Pay in 4?

Suppose a shopper places a $200 order and chooses Pay in 4. A simple schedule looks like this:

Klarna’s current U.S. Pay in 4 page says payments are generally collected every two weeks and that customers pay no interest or fees when they stay on schedule.

So how does Klarna make money on Pay in 4? The merchant still has a commercial payment relationship with Klarna. Klarna can earn transaction revenue while managing payment collection from the customer.

The exact merchant deduction should not be generalized into one percentage because Klarna’s current documentation states that pricing depends on the applicable price plan and transaction conditions. The shopper can therefore receive a genuine interest-free schedule while the transaction remains commercially valuable to Klarna.

What Fees Does Klarna Charge?

There is no single “Klarna fee” because merchant charges and consumer charges work differently.

Fees for Merchants

Businesses generally pay Klarna according to their merchant agreement. The amount can involve a percentage-based component, a fixed transaction amount, or a combination of both, and the applicable rate can vary by payment program and commercial terms.

Because pricing varies between merchants and markets, ecommerce teams should use a current Klarna quote or price plan rather than relying on a static fee table from an older third-party article. The same principle matters when comparing payment options and transaction costs across ecommerce platforms.

Fees and Interest for Consumers

Consumer costs depend on the product. For U.S. Pay in 4, Klarna currently says there are no fees when payments are made on time. If an attempted payment remains unsuccessful, a late fee of up to $7 may apply, subject to the product’s aggregate cap. For longer-term U.S. financing, current disclosures show APRs from 0.00% to 35.99% depending on the offer and borrower.

Other Klarna products can have their own service charges, card terms, subscription fees, or market-specific conditions. The practical takeaway is simple: do not treat every Klarna product as financially identical.

How Much Money Does Klarna Make, and Is Klarna Profitable?

Revenue and profit are not the same thing. Klarna can earn money from a payment or financing transaction and still incur processing, credit, funding, technology, marketing, and operating costs to provide it.

Revenue and Profit Trend

Klarna’s 2025 annual report shows revenue rising from $2.276 billion in 2023 to $2.811 billion in 2024 and $3.509 billion in 2025. Net results were a $244 million loss in 2023, a $21 million profit in 2024, and a $273 million loss in 2025.

Klarna annual revenue and net profit/loss, 2023–2025. Source: Klarna 2025 Annual Report.

The 2025 net loss should be read alongside Klarna’s adjusted figures. Klarna reported $65 million in adjusted operating profit for 2025, while its annual report explained that rapid Fair Financing growth increased upfront expected-credit-loss provisions before all associated interest income was recognized over the life of the loans.

Is Klarna Actually Profitable?

Klarna’s profitability depends on the period and metric being discussed. It posted a $21 million net profit in 2024, a $273 million net loss in 2025, and then returned to positive quarterly reported earnings in 2026. In Q2 2026, the company reported $27 million in operating income and $9 million in net income, compared with an operating loss of $46 million and a net loss of $53 million a year earlier.

So the useful answer to “how does Klarna make a profit?” is not simply “merchant fees minus costs.” Profitability depends on whether revenue from merchants, consumers, interest, advertising, cards, and financial activities exceeds transaction costs and the wider operating expense base.

Klarna uses a non-IFRS measure called Transaction Margin Dollars (TMD) to show what remains after the major transaction-level costs. In simplified form:

Revenue – processing and servicing – credit-loss provisions – funding costs = Transaction Margin Dollars

For Q2 2026, the numbers were:

Credit Losses

If consumers do not repay credit Klarna has extended, the company can absorb losses or recognize provisions for expected losses. In Q2 2026, provisions for credit losses were $192 million, equal to 0.52% of GMV.

This is one reason underwriting quality matters so much. Revenue can grow quickly, but poor credit performance can erase the margin created by merchant fees or financing income.

Funding Costs

Klarna may settle with a merchant before receiving all of the shopper’s installments. Longer financing stretches that timing difference further, so the capital supporting consumer receivables has a cost.

Klarna reported $171 million of funding costs in Q2 2026. Its Q2 results also said about 90% of funding sat in low-cost consumer deposits, which gives the company a funding advantage compared with a model that relies more heavily on wholesale borrowing.

That is why an interest-free BNPL transaction is attractive only when the revenue generated by the relationship is sufficient to cover processing, servicing, credit risk, funding, and the wider cost base.

Why Are Merchants Willing to Pay Klarna?

From an ecommerce merchant’s perspective, giving a payments provider part of a transaction can look expensive. But payment acceptance and secure payment gateways are already part of the cost of doing business online.

Merchants may already pay for payment processing, fraud prevention, chargeback management, gateways, customer acquisition, checkout technology, and financing options. Klarna can bundle several parts of that equation into one commerce relationship.

Its flexible options give shoppers more choice at checkout, while Klarna manages the repayment schedule instead of requiring the retailer to collect installments itself. The potential value therefore comes from the combination of flexible checkout, settlement, infrastructure, risk management, and broader shopping exposure.

That does not mean Klarna automatically improves results for every store. Merchants still need to compare the cost of offering BNPL against changes in conversion, average order value, customer acquisition, returns, margins, and payment expenses.

The better question is not simply, “What percentage does Klarna charge?” It is: does the incremental business value exceed the incremental cost for this store? That is a more useful way to evaluate the overall checkout experience and any alternative payment option.

What the Klarna Revenue Model Tells Us About BNPL

The older, simpler explanation of Klarna was that merchants pay a fee so shoppers can buy now and pay later. That remains an important part of the model, but Klarna’s audited 2025 reporting and current 2026 results show a much broader business.

The modern revenue model spans merchant payments, consumer credit, consumer services, cards, advertising, subscriptions, shopping discovery, and receivable-financing activities.

In Q2 2026, Klarna generated $707 million in transaction and service revenue, $266 million in interest income, $69 million in gains on sales of consumer receivables, and $1.042 billion in total revenue.

For shoppers, “interest-free” should therefore not be interpreted as “Klarna does not make money.” For merchants, Klarna should be evaluated as more than a financing button: it is part payment network, part lending platform, and increasingly part commerce and customer-discovery ecosystem.

Who Are Klarna’s Competitors?

Klarna competes with payment networks and BNPL specialists across different products and markets. A commonly cited competitor set in earlier Klarna business-model research includes Affirm, Sezzle, PayPal, Afterpay, Splitit, and Zip. The competitive overlap is not identical—some focus more on consumer lending, some on installment checkout, and some operate inside much larger payment ecosystems.

Affirm

Affirm offers pay-over-time products that include installment and monthly-payment options. Its model overlaps most directly with Klarna in merchant checkout financing and consumer payment flexibility.

Sezzle

Sezzle is a BNPL provider with installment-payment products and consumer shopping features. It competes for merchant integrations and shoppers who want to spread purchases over several scheduled payments.

PayPal

PayPal competes through Pay Later products embedded in one of the world’s largest digital-wallet and merchant-payment networks. Its advantage is that many merchants and shoppers already use PayPal at checkout.

Afterpay

Afterpay is a Block-owned BNPL brand built around installment payments. It competes with Klarna for merchant placement at checkout and for consumers seeking short-term payment flexibility.

Splitit

Splitit takes a different approach by enabling installments using a shopper’s existing credit-card line in supported implementations. That makes it a payments-infrastructure alternative rather than a direct copy of every Klarna product.

Zip

Zip offers flexible installment payments through its BNPL ecosystem. Like Klarna, it competes for both merchant distribution and consumer engagement beyond a single checkout transaction.

Final Thoughts

So, how does Klarna make money? For its best-known interest-free payment products, the answer begins with merchants. A shopper may pay no interest while the retailer pays Klarna for payment processing, settlement, flexibility, and related infrastructure.

But today’s Klarna goes much further. Longer-term financing generates interest. Consumer services and memberships create additional income. Cards expand Klarna into everyday spending. Advertising monetizes product discovery. Sales of selected consumer receivables add another financial component to the model.

That diversification explains how a company built around “buy now, pay later” can generate substantial income without requiring every shopper to pay interest.

For ecommerce merchants, the practical takeaway is straightforward: interest-free for the customer does not mean cost-free for the payment ecosystem. The business case for Klarna depends on whether the added payment flexibility, checkout experience, reach, and sales impact are worth the merchant economics involved.
