What a Custom SaaS MVP Actually Costs in 2026
"How much does it cost to build a SaaS MVP?" is one of the most common questions we get, and it's also one of the hardest to answer honestly with a single number — because the honest answer depends entirely on decisions the client hasn't made yet. Here's how we break it down for people evaluating a build in 2026.
The rough ranges
For a genuinely custom MVP — not a no-code prototype, but a real, production-grade full-stack application (think React/Next.js frontend, Node.js backend, PostgreSQL, proper auth and billing) — realistic ranges look like:
- Lean MVP (single core workflow, one user role, basic auth/billing): roughly €8,000–€18,000
- Standard MVP (multiple user roles, integrations, dashboard, admin panel): roughly €18,000–€40,000
- Complex MVP (multi-tenant architecture, real-time features, third-party API-heavy): €40,000+
These are studio-build ranges, not solo-freelancer ranges — they reflect proper architecture planning, QA, and a build that won't need to be rebuilt six months after launch.
What actually moves the number
Number of user roles. A single-role app (just "users") is far simpler than one with admins, teams, permissions, and billing tiers baked in from day one.
Third-party integrations. Every payment processor, CRM sync, or external API adds real engineering time — not just for the "happy path," but for handling what happens when that third-party service fails or rate-limits you.
Multi-tenancy. If multiple companies/organizations will use your product with data isolation between them, this is an architectural decision that has to be made correctly from the start — retrofitting it later is expensive.
Real-time features. Live collaboration, notifications, or dashboards that update without a refresh require WebSocket infrastructure that a simple CRUD app doesn't need.
The trap: building the MVP twice
The single biggest cost overrun we see isn't scope creep during the build — it's founders who go cheap on the first build (a rushed, no-architecture version), get early traction, and then have to pay for a full rebuild because the codebase can't handle real users. A properly architected MVP costs more upfront but is the version you can actually keep building on.
What we'd ask before quoting
Before we give any client a real number, we need to know: how many user roles, what needs to happen in real time (if anything), which third-party services are non-negotiable, and whether multi-tenancy is a launch requirement or a "later" problem. Get those four answers right and the cost estimate stops being a guess.
