Stripe 2.9% vs Adyen 0.6% vs Braintree 2.59%: 2026 Fees

At enterprise volume, Adyen is the cheapest of the three — interchange-plus from roughly 0.6% + €0.11 versus Stripe's default 2.9% + 30¢ and Braintree's 2.59% + 49¢. That's the short answer. The longer answer is more interesting, because sticker price is almost never what an enterprise actually pays.

Stripe processed $1.9 trillion in total payment volume in 2025, up 34% year-over-year and enough to pass PayPal's $1.79 trillion for the first time. Adyen processed €803.8 billion in H1 2026 alone, up 24% year-over-year, on its way to another full-year record. Braintree, folded inside PayPal's total payment volume, is the smallest standalone story of the three but the default rail for native PayPal and Venmo — and it just posted a ninth straight quarter of profitable growth. Each took a different bet on how payments should be priced, built, and sold — and at the enterprise tier those bets produce very different bills. As of August 2026, Stripe carries a $159 billion valuation from its February 2026 employee tender offer, up from $91.5B a year earlier.

Stripe vs Adyen vs Braintree: enterprise payments compared in 2026

For enterprise payment processing in 2026, Adyen offers the lowest blended cost through interchange-plus pricing, Stripe offers the best developer tooling and embedded-finance stack at a higher default rate, and Braintree differentiates on native PayPal and Venmo acceptance. The right choice depends on annual volume, whether you sell software or goods, and how much of your stack you want to own versus buy.

Adyen's markup is a fixed acquiring fee on top of true interchange, so its blended rate falls as ticket size and volume rise — the opposite of Stripe and Braintree's flat percentages.

How the three pricing models actually differ

The single biggest decision in enterprise payment processing in 2026 is flat-rate versus interchange-plus. It sounds like accounting trivia. It is worth millions at scale.

Run the math on a merchant doing $500M a year at a $120 average order value. On Stripe's flat 2.9% + 30¢ that's roughly $14.5M in card fees plus ~$1.25M in per-transaction charges — call it $15.75M. On Adyen's interchange-plus, with US blended interchange near 1.9% and a 0.6% markup, the all-in lands closer to $12.5–13M. That ~$3M annual delta is exactly why large omnichannel retailers default to Adyen, and why Stripe quietly offers interchange-plus to anyone big enough to ask.

Where Stripe wins enterprise payments in 2026

Stripe wins enterprise payment processing in 2026 when the customer is a software company, a marketplace, or a platform that wants to monetize payments itself. Stripe Connect lets a platform onboard and pay out sub-merchants and take a slice — the core of the embedded-finance wave. No competitor matches Stripe's API surface, documentation, or speed-to-integration.

The trade-off is cost. Stripe's default rate is the highest of the three, and while it negotiates aggressively above ~$1M/month, you have to be a real account to unlock it. If payments are a feature of your product, Stripe is usually worth the premium. If payments are just a cost center, the premium is harder to justify. Stripe is also pushing that same bundling logic into AI spend — its reported $8 billion-plus acquisition of AI model router OpenRouter in August 2026 signals it wants to own token-cost management the same way it owns payment processing.

Where Adyen and Braintree win enterprise payments

Adyen wins the global omnichannel enterprise — the retailer or brand that sells in stores, online, and in-app across dozens of countries and wants one platform, one settlement, and one reconciliation. Adyen built a single financial stack rather than stitching acquirers together, which is why it banks Uber, Spotify, McDonald's, and Microsoft. Its take rate sits near 0.6%, a fraction of Stripe's sticker rate, because it sells to merchants whose own margins demand it.

Braintree's honest position in 2026 is narrower than it was five years ago. Its 2.59% + 49¢ is competitive, and as PayPal's gateway it's the cleanest way to accept PayPal and Venmo natively alongside cards. But on pure card processing it doesn't out-price Adyen or out-build Stripe. It wins on the wallet, not the rail.

What H1 2026 earnings changed

All three companies reported fresh numbers between June and August 2026, and the picture shifted at the margins. Adyen's H1 2026 results showed processed volume up 24% year-over-year to €803.8 billion, but net revenue grew only 19% (21% at constant currency) to €1,302.9 million — a gap analysts read as take-rate compression as large customers scale into Adyen's volume-tiered discounts. Meanwhile PayPal's Q2 2026 earnings report disclosed that Braintree's PSP volume growth accelerated to 13%, its ninth consecutive quarter of profitable growth — a reversal of the shrinking-Braintree narrative that dominated 2023 and 2024. Stripe has not published a mid-2026 volume update since its 2025 annual letter, so its most current disclosed figures are still the $1.9 trillion FY2025 volume and the $159 billion valuation confirmed in its February 2026 tender offer.

What the headline numbers miss

Adyen's cost advantage is real but not static. Its fixed acquiring markup means the blended rate a merchant pays keeps falling as it grows — which is exactly the dynamic that produced the H1 2026 take-rate softness analysts flagged: Adyen's biggest customers are graduating into cheaper tiers faster than new volume replaces the margin. One read on this: the same mechanic that makes Adyen the low-cost option for a $500M merchant today will keep compressing Adyen's own economics as its customer base matures, which is a risk to Adyen's shareholders more than to a buyer choosing a processor — but it is a reason the €0.11 fixed markup should not be treated as permanently fixed in a vendor negotiation. None of the three companies' growth rates above are apples-to-apples: Stripe's is a full calendar year, Adyen's a half year, and Braintree's a single quarter, so treat them as directional, not as a ranked scoreboard.

The verdict: which processor wins enterprise payments in 2026

There is no single winner — but there is a clear answer per profile. For a global retailer or omnichannel brand processing serious volume where every basis point matters, Adyen wins on cost and platform unification. For a SaaS company, marketplace, or platform that treats payments as a product surface, Stripe wins on developer experience and embedded fintech. For a US consumer brand that lives and dies by PayPal and Venmo at checkout, Braintree wins on wallet-native acceptance.

If forced to name one overall winner for the median enterprise buyer in 2026, it's Adyen — its interchange-plus model is structurally cheaper at scale and its single global platform removes the integration tax that flat-rate processors hide. But "cheapest" only wins if cost is your bottleneck. For most software-led companies, the few extra basis points Stripe charges buy speed, optionality, and a fintech stack that turns payments from a line item into a revenue line.
