SaaS Development Cost Calculator
Estimate your custom SaaS platform development cost based on real 2026 project data from European nearshore studios. Adjust tier, multi-tenancy, integrations, and compliance to land within 20% of a post-discovery quote.

Years 2+ ongoing
Estimates assume a European nearshore studio at €70–110/hr senior, €90–130/hr lead. UK/US onshore rates are typically 2× higher. Real project quotes depend on architecture decisions surfaced in discovery — see the methodology below.
Methodology — How the Numbers Work
The cost calculator uses a tier-base + multiplier structure that mirrors how competent European nearshore studios actually quote real projects:
Tier base: MVP (€20K–€50K) for validating market hypothesis, Growth Platform (€50K–€150K) for proven demand scaling, Enterprise (€150K–€300K+) for compliance-heavy multi-region platforms. Tier alone explains ~60% of cost variance.
Multi-tenancy multiplier: Single-tenant adds 0%, shared schema with tenant_id adds 5%, schema-per-tenant adds 15%, database-per-tenant adds 30%. The choice depends on enterprise customer isolation requirements.
User roles: Each role beyond admin adds €4,000 in QA effort. A 4-role platform (admin, manager, member, billing-admin) typically adds €12,000 vs a single-role consumer SaaS.
Integrations: Each third-party integration (Stripe, Salesforce, Slack, Zapier, EHR systems, ERP) adds €8,000 on average. Complex integrations with bidirectional sync or webhook handling cost more; simple read-only integrations less.
Compliance overhead: CCPA adds 6%, GDPR 10%, SOC 2 Type II readiness 13%, HIPAA 18%, multi-framework 25%. Retrofitting compliance after launch costs 5–8× this upfront investment.
Discovery sprint: A 2-week paid discovery adds €8,000 but reduces total project variance by ~30% according to our 15-project nearshore lessons analysis. Skipping discovery typically costs more than including it.

Next step: turn this estimate into a real plan
The calculator output is a planning anchor. Real quotes follow a 2–3 week paid discovery sprint that produces architecture decision records, a fixed scope, and a timeline you can commit to. We work with founders and CTOs across Europe and North America to build serious SaaS platforms.
