The verdict in three sentences
A custom B2B SaaS MVP in Berlin in 2026 costs 30,000 to 70,000 EUR and ships in 8 to 14 weeks. Budget an extra 500 to 1,500 EUR/month for infrastructure and third-party SaaS tools (auth, email, payment, monitoring). The trap is not the build price but the temptation to add features before validating a single paid pain point.
The scope of an MVP that costs 30,000-70,000 EUR
An MVP is not a smaller version of the final product: it is the smallest set that proves customers will pay. Here is the typical scope and its pricing.
| Block | Content | Estimate | Duration |
|---|---|---|---|
| Core feature | The single value-creating capability | 12,000 - 28,000 EUR | 4 - 6 wks |
| Authentication | Accounts, roles, invitations | 3,000 - 6,000 EUR | 1 - 2 wks |
| Billing | Subscription, payment, invoices | 4,000 - 9,000 EUR | 1 - 2 wks |
| Dashboard | Metrics, onboarding, settings | 5,000 - 12,000 EUR | 1.5 - 3 wks |
| Infra & deploy | CI/CD, hosting, monitoring | 3,000 - 8,000 EUR | 1 - 2 wks |
| Design & UX | UI kit, key flows | 3,000 - 7,000 EUR | In parallel |
A well-scoped 45,000 EUR MVP beats a 90,000 EUR product still searching for its market.
Recurring costs and cost per iteration
After launch the real work begins: iterating fast on feedback. Here are the recurring items (2026 order of magnitude).
| Item | 2026 estimate | Note |
|---|---|---|
| Hosting / infra | 150 - 600 EUR/month | By traffic and data |
| Third-party SaaS | 200 - 700 EUR/month | Auth, email, payment, analytics |
| Monitoring / security | 100 - 300 EUR/month | Logs, alerts, backups |
| Product iteration | 4,000 - 12,000 EUR/cycle | 3 - 5 week cycle |
| Support / fixes | 0.5 - 2 days/month | Bugs and small requests |
Expect a cost per iteration of 4,000 to 12,000 EUR for a 3 to 5 week cycle: that cadence turns an MVP into a profitable product.
Mini case study
Thomas, founder of an HR startup in Berlin, wants to validate a tool for tracking annual reviews. Instead of a full product at 120,000 EUR, he launches an MVP at 42,000 EUR in 11 weeks: one core feature (review workflow), auth, billing and dashboard. With 1,000 EUR/month of recurring costs, he signs 14 customers at 79 EUR/month in three months, i.e. 1,106 EUR of MRR. After two 8,000 EUR iterations he reaches 32 customers: the MVP proved the market for a third of the initial budget, and every iteration euro is now guided by paying customers.

FAQ
What is the difference between an MVP and a full product?
An MVP proves a pain is worth paying for, with the minimum of features. A full product comes after product-market fit, once the market is validated.
What should you cut in a first MVP?
Multi-language, complex roles, secondary integrations, native mobile apps and customizations. Keep one core feature, auth, billing and a simple dashboard.
How long does delivery take?
8 to 14 weeks for a serious MVP. Below 8 weeks you often cut security or billing; above 14 you over-build before validating.
Should billing be in the MVP?
Yes. Charging from day one is the best value test. Simple billing (monthly subscription) costs 4,000 to 9,000 EUR and avoids distorting your market signals.
How much does each post-launch iteration cost?
From 4,000 to 12,000 EUR per 3 to 5 week cycle. The budget depends on feedback volume and the complexity of prioritized features.
