Stripe vs a dedicated merchant account
Stripe is a developer favorite for a reason. But for higher-volume or in-person businesses, a merchant account on interchange-plus usually costs less. When to use which.
Stripe is a developer’s dream, and that is not marketing. Its API, documentation, and tooling are best in class, which is exactly why so many startups and software products build on it. But "best developer experience" and "lowest cost to accept a card" are different questions. For a lot of businesses, especially higher-volume and in-person ones, a dedicated merchant account on interchange-plus quietly wins on price. Here is how to tell which one is right for you.
What Stripe publishes
Stripe’s pricing is public and, like all flat rates, simple by design. As of June 2026:
| Payment type | Published Stripe rate |
|---|---|
| Online cards | 2.9% + 30 cents |
| In-person (Terminal) | 2.7% + 5 cents |
| International cards | + ~1.5% surcharge |
| Currency conversion | + ~1% surcharge |
Where Stripe is genuinely worth it
Where a merchant account wins
Stripe’s flat rate, like any flat rate, sits above your true interchange cost. A merchant account on interchange-plus charges the network’s real cost plus a small fixed markup, so you stop overpaying on cheap cards.
Stripe 2.9% + 30c
vs interchange-plus ≈ 2.3% all-in
Stripe 2.7% + 5c
vs interchange-plus ≈ 2.0% all-in
Typical savings at scale
for higher-volume merchants
The more you process and the more card-present you are, the wider the gap. For a developer-light business taking a lot of cards, the flat-rate convenience is often pure cost.
Choose by what you actually need
- Choose Stripe if you need its API, build custom payment flows, run a marketplace, or value developer tooling over a lower rate.
- Choose a merchant account if you take steady or in-person volume and want the lowest honest cost on interchange-plus.
- Sometimes both. Some businesses keep Stripe for online and add a merchant account for in-person. We will tell you if that split makes sense.
The bottom line
- Stripe’s developer tooling is best in class and a real reason to use it.
- Its flat rate, like all flat rates, sits above your true interchange cost.
- Interchange-plus merchant accounts usually win on price for higher-volume and in-person businesses.
- Do not abandon genuine engineering value just to shave basis points.
- Compare both on your statement, and we will say honestly if Stripe is already best for you.
