The verdict in three sentences
A B2B SaaS MVP in Berlin costs between 25,000 and 80,000 EUR (net) in 2026, for 3 to 5 months of development at a daily rate of 450 to 650 EUR (net). The key is shipping one flawless core feature, plus auth and billing, without scattering effort. Plan a post-launch iteration budget equal to 30 % of development cost to turn the MVP into a sellable product.
What belongs (and does not) in an MVP
An MVP is not a cut-price version: it is the minimal version that proves value with your first paying customers. Everything that is not the core feature is deferred.
| Component | In the MVP? | Indicative cost (EUR net) |
|---|---|---|
| Core feature (single) | Yes | 12,000 - 40,000 |
| Authentication | Yes | 3,000 - 6,000 |
| Billing (Stripe) | Yes | 4,000 - 9,000 |
| Basic admin dashboard | Yes | 3,000 - 8,000 |
| Full multi-tenant | No (v2) | 8,000 - 20,000 |
| Native mobile app | No (v2) | 25,000+ |
By limiting to one core feature, you hold the 3 to 5 months and the low budget. Adding a second major feature pushes the project toward 60,000-80,000 EUR (net) and a full 5 months.
Technical debt and iteration budget
An MVP accepts reasoned technical debt: you move fast to validate the market. But that debt has a deferred cost you must budget.
| Post-launch item | 2026 range | Comment |
|---|---|---|
| Cloud hosting | 150 - 500 EUR/month | grows with users |
| Product iteration | 30 % of initial dev | 7,500 - 24,000 EUR |
| Debt repayment | 10-15 % of dev | targeted refactoring |
| Early-adopter support | 0.5-1 day/week | often the founder |
The iteration budget is the most underestimated: after the first customers, you must adjust onboarding, fix friction and add requested functions. Without that 30 %, the MVP stays a prototype that does not convert.

Mini case study
Julia, founder of a B2B startup in Berlin, wants to validate a compliance-tracking tool for SMEs. She scopes her MVP to a single core feature (checklist + alerts), auth and Stripe billing, for 42,000 EUR (net) over 4 months. She reserves 30 % for iteration, i.e. 12,600 EUR, plus 300 EUR/month of hosting. Target: 30 customers at 89 EUR/month within 8 months, i.e. 2,670 EUR MRR, about 32,000 EUR ARR. The dev + iteration pair (54,600 EUR) is covered by year-two ARR, while the market is validated with real paying customers from month five.
FAQ
What is the floor budget for a credible SaaS MVP? Around 25,000 EUR (net) for a simple core feature, auth and billing. Below that, it is an unbillable prototype, not a sellable product.
How long to ship? Budget 3 to 5 months for a single-core-feature MVP. A second major feature or full multi-tenant pushes beyond 5 months.
Do I really need to budget 30 % iteration? Yes. The post-launch iteration budget (7,500 to 24,000 EUR) turns a prototype into a converting product; omitting it is the most common mistake.
What day rate in Berlin in 2026? Between 450 and 650 EUR (net), a notch below top hubs, with full-stack profiles used to startup pace.
Is multi-tenant essential at launch? No. Full multi-tenant (8,000-20,000 EUR net) is justified in v2, once traction is proven. At launch, simple logical isolation is enough.
