The verdict in three sentences
Online payment cost is made of three blocks: per-transaction fees, PSP subscription and technical integration. Stripe shines through simplicity (1.4% + 0.25 EUR within the EU, no subscription); a bank PSP can be cheaper at high volume but adds 15 to 40 EUR/month. In 2026, 3D Secure is mandatory and a card failure rate of 3 to 6% weighs on your revenue as much as the fees themselves.
Stripe vs bank PSP
| Criterion | Stripe | Bank PSP |
|---|---|---|
| EU card fees | 1.4% + 0.25 EUR | 0.8 to 1.2% + fixed fees |
| Non-EU card fees | 2.9% + 0.25 EUR | 1.8 to 2.5% |
| Monthly subscription | 0 EUR | 15 to 40 EUR |
| Fixed fee per transaction | 0.25 EUR | 0.10 to 0.20 EUR |
| Setup time | 2 to 4 weeks | 3 to 6 weeks |
| 3D Secure | Included | Included |
| Documentation / DX | Excellent | Variable |
The rule: Stripe is unbeatable below 200 000 EUR of annual card volume; beyond that, a bank PSP negotiated at 0.9% can win despite the subscription.
Cost per revenue tier
| Annual card revenue | Stripe (1.4% + 0.25 EUR) | Bank PSP (1.0% + 20 EUR/mo) |
|---|---|---|
| 50 000 EUR | ~950 EUR | ~740 EUR |
| 150 000 EUR | ~2 850 EUR | ~1 740 EUR |
| 300 000 EUR | ~5 700 EUR | ~3 240 EUR |
| 500 000 EUR | ~9 500 EUR | ~5 240 EUR |
*2026 estimate, average basket 80 EUR. The bank PSP wins from 100 000 EUR of card volume, but Stripe stays simpler to operate.*
Technical integration cost
| Integration item | 2026 cost (order of magnitude) |
|---|---|
| Standard Stripe integration (Checkout) | 2 500 to 4 000 EUR |
| Custom integration (Payment Intents) | 4 500 to 7 000 EUR |
| 3D Secure + failure handling | Included |
| Webhooks + accounting reconciliation | 1 000 to 2 500 EUR |
| Payment e2e testing | 800 to 1 500 EUR |

Mini case study
Sophie, CFO of a cosmetics SMB, takes 280 000 EUR of card revenue/year, average basket 65 EUR. On Stripe she pays 1.4% + 0.25 EUR = about 5 000 EUR/year. By negotiating a bank PSP at 1.0% + 20 EUR/month, she drops to 3 040 EUR/year, i.e. 1 960 EUR of annual savings. The custom PSP integration costs 5 500 EUR: it pays back in 2.8 years. But by cutting the card failure rate from 5% to 2% (better checkout UX), she recovers 8 400 EUR of revenue: that is the real gain.
