What SaaS Software Actually Costs to Build — By Stage, Type, and Team
A senior engineering team's honest breakdown of SaaS development costs, built from real project data — not a lead-gen guess. Get a written range in two minutes with our free SaaS cost calculator, no email required.
| Stage | What you get | Typical cost |
|---|---|---|
| Prototype / PoC | Clickable proof of concept, one core flow, no production infrastructure | $3,000 – $9,000 |
| MVP | One core flow shipped end-to-end, real auth & billing, ready for first users | $13,000 – $27,000 |
| Production-ready | Full feature set, multi-tenant architecture, QA-hardened, ready to scale | $25,000 – $75,000 |
| Scale-ready | Performance-tuned for growth, advanced permissions, usage-based billing | $55,000 – $110,000 |
| Enterprise-grade | SOC 2-ready architecture, SSO, audit logging, dedicated DevOps & security | $140,000 – $190,000+ |
Figures reflect senior-only, EU-timezone-aligned engineering rates. Get a range built around your own feature list with the SaaS spend calculator — it takes about two minutes.
Significantly. A marketplace with two-sided payments costs more to build correctly than an internal tool with one user role — even at the same feature count.
Illustrative split for a typical MVP-stage B2B SaaS build. Your own breakdown will shift depending on feature count and complexity — the calculator generates one specific to your project.
| Discipline | Share of budget | What it covers |
|---|---|---|
| Backend | ~30% | API, database, multi-tenancy, billing logic |
| Frontend | ~28% | Application UI, state management, responsive layout |
| Product & UX | ~18% | Flows, wireframes, design system |
| QA & Testing | ~10% | Automated tests, manual QA passes, bug triage |
| DevOps & Infra | ~6% | CI/CD, cloud environment, monitoring setup |
| Project Management | ~8% | Sprint planning, demos, client communication |
Answer a few questions about your SaaS type, stage, scale, and feature list, and get an instant build-cost range, timeline, and team composition — the same model behind every number on this page. No email required.
The build is a one-time cost. Running the product is not — plan for these before you sign a contract, not after.
| Ongoing cost | Typical range | Notes |
|---|---|---|
| Cloud hosting | $50 – $2,000+/mo | Scales with usage; a lean MVP starts near the bottom |
| Third-party APIs | $0 – $500+/mo | Email, SMS, payments, analytics — usage-based |
| AI/LLM inference | $0 – $1,000+/mo | Only for AI-native features; scales with usage |
| Monitoring & observability | $0 – $200/mo | Error tracking, uptime, logging |
| Ongoing maintenance | 10–20% of build cost / yr | Dependency updates, bug fixes, small improvements |
| Approach | Sticker price | What usually happens |
|---|---|---|
| Junior-heavy offshore team | Lowest hourly rate | Architecture rework 6–12 months in; the "cheap" build gets rebuilt anyway |
| Large agency, mixed seniority | Highest sticker price | Account management overhead; your project is one of many |
| Solo freelancer | Low, but a single point of failure | No coverage for illness, no second opinion on architecture calls |
| Senior-only team, fixed scope | Mid-range, no surprises | Correct architecture from sprint one, written scope, demo every 2 weeks |
This is the model our own SaaS development team runs on: senior engineers only, EU-timezone overlap, and a written scope document instead of an open-ended estimate.
If your project isn't SaaS-specific — a mobile app, an internal tool, or a general web platform — our broader software development cost estimation calculator covers five project types in five quick questions.
Most SaaS MVPs cost $13,000–$27,000 with a senior engineering team, and production-ready platforms typically run $25,000–$75,000. The exact figure depends on your SaaS type, feature count, and compliance needs — use the SaaS cost calculator for a range scoped to your project.
A free SaaS spend calculator, like the one on this page, is the fastest way to get a real number — it takes about two minutes and needs no email or sales call. For a binding number, a written scope from an engineering team is the next step.
A SaaS MVP — one core flow shipped end-to-end with real authentication and billing — typically costs $13,000–$27,000 and takes 8–16 weeks with a senior team. Our SaaS MVP cost calculator breaks this down by your specific feature list.
SaaS products need application logic a marketing site never touches: multi-tenant data isolation, recurring billing, authentication and permissions, and infrastructure that stays correct as usage grows. That's ongoing engineering, not a one-time build.
Our calculator runs on the same pricing model we use to scope real client projects — it's a genuine range, not a lead-gen placeholder. It won't replace a written estimate after a scoping call, but it's accurate enough to budget against.
A real estimate covers product & UX, frontend, backend, QA, DevOps setup, and project management — see the cost breakdown table above. It does not include ongoing hosting, third-party API usage, or maintenance, which are separate recurring costs.
An MVP typically takes 8–16 weeks, a production-ready platform 16–28 weeks, and an enterprise-grade build 32–60 weeks. Timeline and cost move together — the calculator estimates both from the same inputs.
