How Much Does It Cost to Build a SaaS in 2026?
The real budget to build a SaaS in 2026: price ranges from MVP to full platform, and the factors that move the bill.
"How much does it cost?" It's every founder's first question. The honest answer: it depends on scope. But here are real ranges, based on projects delivered in 2026.
What moves the price
Three "SaaS" projects can have very different budgets depending on:
- Functional scope: a focused MVP costs a fraction of a full platform
- Integrations: payments, third-party APIs, real-time sync
- Embedded AI: agents, recommendations, language processing
- Design: an adapted template or a bespoke identity
2026 price ranges
MVP — €10,000 to €15,000
A first version that solves one precise problem, delivered in 4 to 8 weeks. Ideal to validate on the market.
Vertical SaaS — €20,000 to €50,000
A complete product with accounts, subscriptions, dashboard and integrations. 8 to 16 weeks.
Platform at scale — €50,000 to €90,000+
Multi-tenant, high performance, AI, compliance. To go from product to company.
Costs not to forget
- Hosting: often a few dozen euros per month on a modern stack
- Maintenance: from €500/month (security, evolutions, support)
- AI integration: €15,000 to €40,000 depending on complexity

Cutting the bill smartly
Start small: a well-scoped MVP costs less and teaches you more than a full platform built blind. Better to validate the idea first, then invest where demand is proven.
