How does the buy-now-pay-later (BNPL) industry and business model work in 2027?
Published Jun 14, 2026 · Updated Jun 14, 2026
Direct Answer
Buy-now-pay-later (BNPL) is a $560 billion global payment category (by 2025 GMV) where the core model is merchants paying fees to boost conversion and order size — not consumers paying interest — though late fees and interest add a second revenue stream. The market grew 13.7% in 2025, with provider revenue climbing from about $44.89 billion (2025) toward $54.56 billion (2026).
The leaders show the model maturing: Klarna posted $2.81 billion in revenue on roughly $105 billion in GMV, Affirm grew revenue 46% to $2.32 billion and crossed into profitability (a $52 million net profit in fiscal 2025), and Afterpay processes billions in US volume.
The revenue comes primarily from merchant processing and commission fees, supplemented by interest (Affirm up to 36%) or late fees (Klarna up to $7, Afterpay up to 25% of the order). Default rates stay low (~1.8–2%), though 34–41% of users report late payments.
For operators, BNPL is a clean lesson in the merchant-funded conversion model, two-sided monetization, and unit economics under credit risk.
1. The Merchant-Funded Model
Merchants pay to lift conversion
The core insight: merchants pay BNPL providers a fee because offering installments boosts conversion and average order value — shoppers buy more when they can split payments. The merchant funds the service because it earns more sales, so BNPL is primarily a merchant-paid conversion tool, not a consumer lending product.
Why merchants accept the fee
A BNPL fee (often higher than a card fee) is worth it if it lifts conversion and basket size by more than the cost. The merchant trades a slice of margin for more and larger sales — the same logic behind any conversion-boosting investment. The provider's pitch is incremental revenue, not just a payment rail.
2. Two-Sided Monetization
Merchant fees plus consumer charges
BNPL providers monetize both sides. The primary stream is merchant processing and commission fees (the bulk of the $12.5 billion in 2024 provider revenue). The second is consumer charges — interest (Affirm up to 36%) or late fees (Klarna up to $7 per payment, Afterpay up to 25% of the order).
Different providers weight these differently.
Different fee philosophies
The fee structures reveal strategy: Affirm charges interest but no late fees; Klarna and Afterpay are 0% interest but charge late fees. Each picks how to monetize the consumer side — transparent interest versus penalty fees — which shapes both economics and brand perception.
3. Unit Economics and Credit Risk
Low defaults, profitability arriving
The unit economics hinge on credit risk. Default rates stay low (~1.8–2%), which is why the model works — but 34–41% of users report late payments, a warning that consumer stress is real. The maturing economics show in Affirm crossing into profitability ($52 million net profit) after years of growth-first.
The path from growth to profit
BNPL grew GMV first and worried about profit later; now leaders like Affirm are proving the model can be profitable at scale. The shift mirrors the broader market move toward efficient growth — the providers that control credit risk and convert GMV into profit are the durable ones.
4. The RevOps and Finance Lessons
Let the party that benefits fund the service
The clearest lesson is the merchant-funded model: the party that benefits (the merchant, who gets more sales) pays for the service. Operators designing pricing should ask who captures the value and structure the fee so the beneficiary funds it. A service that demonstrably lifts a partner's revenue can be funded by that partner, not the end user.
Monetize multiple sides where you can
BNPL earns from merchants and consumers both. Operators running a platform or marketplace should consider two-sided monetization — charging each side for the value it receives — since it maximizes total revenue, balanced against the friction each fee adds. The strongest models capture value from every party they serve.
Mind the unit economics under risk
BNPL works because default rates are low — but the 34–41% late-payment rate is a flashing warning that the economics depend on credit risk staying controlled. Operators whose model carries risk (credit, returns, churn) should obsess over the loss rate, because a model that looks profitable on volume can invert if the risk metric drifts.
Watch the denominator of risk, not just the top line.
5. What to Watch
The questions for 2027 are how regulation reshapes BNPL (consumer-protection rules are tightening), whether default rates hold as the economy shifts, and how bank-backed installment programs and Apple Pay intensify competition. With GMV at $560 billion and leaders like Affirm now profitable, the category is maturing from land-grab to discipline.
The durable lessons transcend BNPL: let the party that benefits fund the service, monetize multiple sides where you can, and mind the unit economics under risk.
FAQ
How big is the BNPL market? About $560.1 billion in global GMV in 2025 (up 13.7%), with provider revenue around $44.89 billion in 2025 rising toward $54.56 billion in 2026. The US market alone is over $122 billion.
How do BNPL companies make money? Primarily from merchant processing and commission fees — merchants pay because BNPL boosts conversion and order size. Providers also earn from consumer interest (Affirm up to 36%) or late fees (Klarna, Afterpay), a two-sided model.
Why do merchants pay for BNPL? Because offering installments lifts conversion and average order value — shoppers buy more when they can split payments. The merchant trades a fee for more and larger sales, making BNPL a merchant-funded conversion tool.
Is BNPL profitable and risky? Default rates stay low (~1.8–2%), and leaders like Affirm have crossed into profitability ($52 million net profit in fiscal 2025). But 34–41% of users report late payments, so the economics depend on controlled credit risk.
What can operators learn from BNPL? Let the party that benefits fund the service (merchants pay because they gain sales), monetize multiple sides where possible, and obsess over the unit economics under risk since a volume-profitable model can invert if loss rates drift.
Bottom Line
BNPL is a $560 billion category built on a merchant-funded model — merchants pay because installments lift conversion and order size — supplemented by consumer interest or late fees in a two-sided model. Leaders like Klarna, Affirm (now profitable), and Afterpay show the economics maturing as default rates stay low near 2%.
For operators, the lessons are exact: let the party that benefits fund the service, monetize multiple sides where you can, and mind the unit economics under credit risk.
