SaaS cost
calculator.

A focused MVP with 5–8 features typically costs £2,500–£8,000 at Inqodo. This covers auth, a core feature set, a basic dashboard, and deployment. Compare this to UK/US agencies charging £20,000–£80,000 for the same scope.

A SaaS MVP with 5–8 core features costs £2,500–£8,000 and takes 4–8 weeks to build. The key is scoping to the smallest set of features that lets you validate the product with real users. Every feature you delay saves £500–£2,000 in upfront cost.

A SaaS spend calculator estimates your ongoing monthly costs to run a SaaS — hosting, database, auth, email, and AI API usage. At launch, monthly SaaS spend is typically £0–£60 using free tiers (Vercel, Supabase, Clerk, Resend). At 1,000+ users or with AI features, expect £50–£300/month.

SaaS Total Cost of Ownership (TCO) is the full 1–3 year cost including: upfront build cost + monthly infrastructure spend + ongoing maintenance + team costs. Most founders only look at build cost. A realistic TCO for a small SaaS over 2 years is build cost + (£100–£300/month × 24) + £500–£2,000/year in maintenance.

Start with this baseline: £0–20/month for database (Supabase), £0/month for hosting (Vercel hobby), £0/month for auth up to 10,000 MAU (Clerk), £10–50/month for email (Resend). When you exceed free tier limits or add AI APIs (OpenAI, Anthropic), budget £100–500/month. Our calculator itemises this by tool.

At launch with under 100 users, you can run entirely on free tiers — Vercel, Supabase, Resend, and Clerk all have generous free plans. Once you hit 1,000+ users or add AI features, expect £50–£300/month. Heavy AI usage (GPT-4, document analysis) can push this to £500–£1,500/month.

A focused MVP with 5–8 features takes 4–8 weeks at Inqodo. Adding admin panels, AI integrations, or native mobile apps extends this to 10–16 weeks. ASAP sprints are possible but cost 10–20% more.

For most web SaaS products: Next.js (frontend + API), Supabase (PostgreSQL + storage + realtime), Clerk (auth), Vercel (hosting), Resend (email). For AI products, add a FastAPI Python service. This stack has the best combination of speed, cost, and scalability in 2025.

No — and you shouldn't. The calculator's V1/V2 split shows you which features to launch with. Most successful SaaS products validated with 3–5 core features before adding complexity. Every feature you delay saves £500–£2,000 in upfront build cost.

We're a lean, senior-only UK-based team. We don't carry the overhead of large agencies (account managers, large offices, sales teams). Our rates reflect the actual cost of delivery — not a margin on top of a margin.

It's a planning baseline, not a quote. Real project costs depend on your exact requirements, feedback during discovery, and any scope changes. The calculator is accurate to ±20% for standard SaaS products. Complex integrations, custom algorithms, or bespoke hardware can push costs higher.
