Klarna vs Afterpay vs Affirm vs Zip: BNPL providers compared
Klarna, Afterpay, Affirm, and Zip differ most on merchant fees, market reach, and repayment terms. All four let a customer split a purchase into instalments while the merchant is paid upfront, and all four charge the merchant more than a card transaction does. The choice between them comes down to where a business sells, what it sells, and what the customer’s basket looks like.
Buy now, pay later has moved well past novelty. Industry estimates put global BNPL gross merchandise volume above USD 560 billion in 2025, growing at roughly 20% annually. At that scale the provider decision is a real commercial one, so here is how the four compare on the things that determine cost and coverage.
How the four BNPL providers compare
| Klarna | Afterpay | Affirm | Zip | |
|---|---|---|---|---|
| Origin | Sweden, 2005 | Australia | United States | Australia |
| Core markets | Global, strongest in Europe and US | Australia, US, UK (as Clearpay) | US and Canada | Australia and US |
| Typical merchant fee | From ~3.29% + $0.30 | Mid range | ~6% + $0.30 | Mid to high range |
| Repayment model | Pay in 4, plus longer terms | Pay in 4 over six weeks | Longer-term instalments, often interest-bearing | Pay in 4, plus longer terms |
| Typical basket | Everyday to mid-ticket | Lower to mid-ticket | Higher ticket | Lower to mid-ticket |
| Consumer late fees | Varies by product | Yes | No | Yes |
| Best fit | Global reach, high frequency | Fashion, beauty, younger shoppers | High-ticket US purchases | Australian market |
Fee figures are published ranges and vary by contract, category, and volume. Treat them as a starting point for negotiation rather than fixed rates.
Klarna
Klarna is the broadest of the four by geography. Founded in Sweden in 2005 and listed on the NYSE in September 2025, it reported USD 33.7 billion in gross merchandise volume in the first quarter of 2026 across roughly 119 million consumers. Its take rate, at around 2.7%, is the lowest of the group, which reflects a business built on high-frequency, lower-value transactions: Klarna’s average order value sits near USD 101.
For merchants, Klarna’s appeal is reach and recognition. It operates across more markets than the other three, which matters for a business selling into several countries and wanting one BNPL relationship rather than a different provider per market. Published merchant rates start around 3.29% plus a fixed fee and rise from there depending on the product and contract.
The tradeoffs are cost at the lower end of the basket range and onboarding time. Klarna’s rate is competitive at its base but climbs for some products, and merchants have reported multi-week approval processes.
Afterpay
Afterpay, trading as Clearpay in the UK, is the most focused of the four on a specific shopper profile: younger customers buying mid-range fashion and beauty. Its model is the classic pay-in-four structure, four interest-free instalments over six weeks, with consumer transaction limits generally capped around USD 2,000.
That cap defines where Afterpay fits. It works well for repeat, lower-ticket retail purchases and poorly for anything expensive. Afterpay charges consumers late fees on missed payments, which is a difference from Affirm and worth knowing if a merchant’s customer base is price-sensitive.
Geographically it is strongest in Australia, where it originated, and has substantial presence in the US and UK. For a fashion or beauty brand targeting a younger demographic in those markets, it is often the first BNPL provider to consider.
Affirm
Affirm is the outlier on basket size and pricing. It holds roughly one-third of US BNPL payment value, focuses on larger purchases, and prices accordingly: its take rate is around 8.9%, more than three times Klarna’s, and merchant rates commonly run near 6% plus a fixed fee. Its average order value, near USD 255, is roughly two and a half times Klarna’s.
That pricing buys a different product. Affirm offers longer repayment terms suited to high-ticket items such as electronics, furniture, and travel, charges consumers no late fees, and reports payment activity to credit bureaus. Merchants in high-ticket categories often find the higher fee is offset by the size of the basket it unlocks.
One honest caveat that vendor comparisons tend to skip: Affirm’s zero-late-fee promise does not mean zero consumer cost. A substantial share of Affirm loans carry interest, so the “interest-free” framing applies to some plans and not others. Merchants should understand which plans they are enabling.
Affirm’s footprint is narrow by comparison, concentrated in the US and Canada. For a merchant selling only into those markets with high-value products, that concentration is not a problem. For a global business it is a limitation.
Zip
Zip requires a caveat that older comparisons miss entirely. Zip has withdrawn from the UK and is winding down its New Zealand operation, leaving its footprint concentrated in Australia and the United States. Any comparison recommending Zip for a market it has left is out of date, and merchants should verify current availability before building an integration.
Where it does operate, Zip offers pay-in-four alongside longer-term options and charges consumers late fees. In Australia, its home market, it remains a meaningful player alongside Afterpay. Outside Australia and the US, it is no longer a practical option.
What BNPL costs merchants, and what you get for it
BNPL is materially more expensive than card acceptance. Published merchant rates across providers run roughly 3.29% to 8% plus a fixed fee, against typical card processing of 2% to 3%. That gap is the central fact of the BNPL decision.
The case for paying it rests on basket economics. Merchants commonly report average order value increases in the range of 10% to 30% after adding BNPL, along with reduced cart abandonment, because the payment option removes the affordability objection at the point of decision. Whether that trade is worth it depends entirely on category and margin: a high-margin, high-ticket retailer can absorb 6% to unlock a larger basket, while a low-margin grocery or commodity seller usually cannot.
The honest way to evaluate this is to model it against your own numbers rather than trusting a general uplift figure. Gr4vy’s guide to how instalment payments work covers the mechanics behind the model.
A regulatory note worth factoring in: the UK Financial Conduct Authority brought BNPL under formal regulation from July 2026, which adds compliance obligations for providers operating there. Merchants selling into the UK should confirm how their provider has adapted.
How to choose a BNPL provider for your market
The decision resolves along three axes.
Geography first. Klarna has the broadest international footprint. Afterpay is strongest in Australia, the US, and the UK. Affirm is US and Canada. Zip is now Australia and the US only. A business selling into a market its preferred provider does not serve needs a different provider for that market, which is how merchants end up running more than one.
Then ticket size. Affirm is built for high-value baskets and prices for them. Afterpay caps out around USD 2,000 and suits lower-ticket retail. Klarna sits in the middle with the broadest range of plan types.
Then customer profile. Afterpay skews young and retail-focused. Affirm suits considered, higher-value purchases. Klarna spans everyday shopping. The provider whose consumer base already overlaps with your customers will convert better than the one with the marginally lower fee.
Gr4vy’s merchant’s guide to BNPL covers the wider question of whether to offer BNPL at all.
Running more than one BNPL provider
Most merchants selling across several markets end up with more than one BNPL provider, because no single provider covers every market well. A business selling in Australia, the UK, and the US could reasonably want Afterpay for Australian retail, Klarna for the UK, and Affirm for high-ticket US purchases. That is three integrations, three contracts, three reporting formats, and three sets of rules about which provider appears at which checkout.
The operational question then becomes how to add, switch, and control providers without an engineering project each time. This is the coordination problem payment orchestration addresses: connecting providers through one integration and deciding through configuration which methods appear in which market.
The practical difference is speed. Ding, the international mobile top-up service operating across more than 140 countries, used no-code rules to show different payment methods by market, prioritising local options where they performed best, and cut the time to integrate a new gateway or local payment method from three to six weeks down to three days. The same principle applies to BNPL: if adding a provider for a new market takes a quarter, it usually does not happen. Gr4vy’s guide to BNPL and payment orchestration covers the setup in more detail.
Frequently asked questions
Which BNPL provider is cheapest for merchants?
Klarna generally has the lowest published starting rate, from around 3.29% plus a fixed fee, and the lowest take rate of the four at roughly 2.7%. Affirm is the most expensive, commonly near 6% plus a fixed fee with a take rate around 8.9%. Rates vary by contract, category, and volume, so published figures are a starting point for negotiation instead of fixed prices.
What is the difference between Klarna and Affirm?
They serve structurally different markets. Klarna focuses on high-frequency, lower-value purchases with the broadest international footprint and an average order value near USD 101. Affirm focuses on higher-ticket US and Canadian purchases with longer repayment terms, no consumer late fees, and an average order value near USD 255. Affirm’s take rate is roughly three times Klarna’s, reflecting the different segments.
Is Zip still available in the UK?
No. Zip has withdrawn from the UK and is winding down its New Zealand operation, leaving its footprint concentrated in Australia and the United States. Merchants should verify current market availability directly with any provider before building an integration, as coverage changes.
How much do BNPL providers charge merchants?
Published merchant rates run roughly 3.29% to 8% of the transaction plus a fixed fee, against typical card processing of 2% to 3%. Klarna starts at the lower end, Affirm and several others sit closer to 6%. The higher cost is generally justified by average order value uplift and reduced abandonment, though whether that trade works depends on category and margin.
Does BNPL increase average order value?
Merchants commonly report average order value increases in the range of 10% to 30% after adding BNPL, along with lower cart abandonment, because the option removes the affordability objection at the point of purchase. These are reported ranges rather than guaranteed outcomes, and the effect varies significantly by category, so it is worth modelling against your own basket data.
Which BNPL provider is best for high-ticket items?
Affirm, in the US and Canada. It is built for larger purchases, offers longer repayment terms suited to electronics, furniture, and travel, and has an average order value roughly two and a half times Klarna’s. Afterpay is a poor fit for high-ticket purchases, with consumer limits generally capped around USD 2,000.
Do merchants need more than one BNPL provider?
Many do, once they sell across several markets, because no single provider has strong coverage everywhere. Klarna is broadest internationally, Afterpay is strongest in Australia and retail markets, Affirm is US and Canada, and Zip is now Australia and the US. Businesses selling into multiple regions commonly run two or three providers and route customers to the right one by market.
Is BNPL regulated?
Increasingly. The UK Financial Conduct Authority brought BNPL under formal regulation from July 2026, adding compliance obligations for providers operating there. Other jurisdictions are at varying stages, and merchants selling internationally should confirm how each provider has adapted in the markets they serve.
Choosing between them
There is no single best BNPL provider, and any comparison that names one is usually selling something. The four occupy genuinely different positions: Klarna is the internationally broad, lower-cost, high-frequency option; Afterpay owns younger retail shoppers in a handful of markets; Affirm is the high-ticket US specialist that prices accordingly; and Zip is now an Australia and US proposition after retreating from other markets.
The right choice follows the market a business sells into and the basket it sells, in that order. Fee differences matter, but a provider two points cheaper in a market where its consumer base is thin will convert worse than a slightly costlier provider customers already use and trust. For businesses selling across several markets, the realistic answer is more than one provider, and the practical question becomes how quickly a new one can be added when a market demands it.
