Quick Answer
A SaaS app costs $5,000–$15,000 for a lean MVP, $15,000–$40,000 for a full MVP, and $40,000–$120,000+ for a complete product in 2026.Our engine sets the median full MVP at $27,500 and median complete product at $80,000. Authentication, billing, and integrations drive most of the cost; infrastructure runs $20–$2,000/month as you scale. Calibrated against 600+ project quotes and public rate benchmarks across 6 markets.

One got the contract structure right; the other shows what an underscoped integration quote turns into. Both patterns repeat constantly in SaaS scoping.
From our project files
SaaS dashboard rebuild — T&M with a cap
320h estimated · $48,000 ceiling · 318h actual
What drove the cost
–Scoped at 320 hours at a $150/hr senior rate — squarely in the $100–$200 senior band
–Dashboard rebuilds iterate; pure fixed-price would have padded the spec, pure T&M had no ceiling
–The not-to-exceed structure costs 5–12% over pure T&M and buys the hard ceiling
What to demand in the quote
–A not-to-exceed ceiling in the contract — the vendor eats overruns, you keep iteration flexibility
–Weekly hours and velocity reporting, not a monthly invoice surprise

From our project files
B2B SaaS — bi-directional HubSpot sync
quoted $3,500 · real cost $11,200 · 14 sync rules
What drove the cost
–The honest scope had 14 distinct sync rules, not the 3 the original agency quote assumed
–Bi-directional sync (leads out, deal stages back) is 60–120 hours of field mapping — read-only sync is a different, cheaper product
–Every sync rule needs retry logic and idempotency or it breaks silently in production
What to demand in the quote
–Every sync rule enumerated in the quote before signing
–Bi-directional priced as bi-directional: $6,000–$15,000, not the $2,500–$5,500 read-only band
–An observability line item (logging, alerts) — skipping it costs $2,000–$15,000 in the first year

MVP vs Full Build — What Should You Start With?
The single biggest cost decision for a SaaS product is scope. A lean MVP with core functionality, user auth, a basic dashboard, and Stripe billing can be built for $5,000–$15,000 by a competent freelancer. A full-featured product with team management, role-based access, advanced analytics, API integrations, and polished onboarding will cost $40,000–$120,000 depending on complexity.
The smart approach is phased delivery. Build the core value proposition first, validate with real users, then invest in the full feature set. This is not just a budget strategy — it is how successful SaaS products like Basecamp, Notion, and Linear launched. They started lean and expanded based on actual user feedback, not assumptions.
Our cost calculator lets you configure exact features and see how each one affects the total. Toggle authentication complexity, add real-time features, or include advanced search — the estimate updates live.
Tech Stack Costs in 2026
Your tech stack affects both initial development cost and long-term infrastructure spend. Here is what the most popular SaaS stacks cost to build with:
Next.js + PostgreSQL + Stripe
Dev: $5,000–$40,000Infra: $20–$200/moBest for: Startups, solo founders, rapid MVPs
Laravel + Vue + MySQL
Dev: $8,000–$50,000Infra: $30–$300/moBest for: Teams with PHP expertise, complex business logic
Django + React + PostgreSQL
Dev: $8,000–$55,000Infra: $25–$250/moBest for: Data-heavy apps, ML features, Python teams
Ruby on Rails + React
Dev: $10,000–$60,000Infra: $40–$400/moBest for: Rapid prototyping, convention-heavy development
Infrastructure costs scale with users. At 100 users, you are paying $20–$50/month. At 10,000 users, expect $200–$2,000/month for hosting, database, CDN, and email. Services like Vercel, Railway, and Render have made this significantly cheaper than traditional AWS setups for early-stage products — Vercel’s published Pro plan, at $20/month, anchors the low end of that hosting band.
Timeline: From Idea to Launch
SaaS timelines depend on scope, team size, and whether you are building from scratch or using a boilerplate:
Beyond development, SaaS products have recurring infrastructure costs. Here is a realistic monthly breakdown for a growing SaaS product — the payment line follows Stripe’s published pricing of 2.9% + 30¢ per successful US card charge:
Hosting (Vercel/Railway/Render)$20–$200/mo
Database (managed PostgreSQL)$15–$150/mo
Email service (Resend/Postmark)$20–$100/mo
Error monitoring (Sentry)$0–$50/mo
Analytics (Mixpanel/PostHog)$0–$100/mo
Payment processing (Stripe)2.9% + $0.30/tx
Domain + SSL$15–$50/year
CDN (Cloudflare)$0–$20/mo
Total (early stage)$70–$670/mo
SaaS Website Cost: Marketing Site vs the Product Itself
"SaaS website cost" means two very different things, and mixing them up wrecks budgets. The marketing site (landing pages, pricing page, blog) and the actual SaaS product are separate builds with separate price tags:
SaaS product: full v1 with dashboard + integrations$40,000–$120,000+
Our rule: spend under 10% of the product budget on the marketing site at launch. A $2,500 Webflow site converts fine while you validate; rebuild it custom once you have paying users. The estimator on this page prices both halves separately so the split stays visible.
Frequently Asked Questions
How much does it cost to build a SaaS MVP?
A SaaS MVP typically costs $5,000–$15,000 with a freelancer or $15,000–$40,000 with an agency. This covers user authentication, a core feature set, basic dashboard, and Stripe integration. Most MVPs take 6–12 weeks to build.
What tech stack is best for SaaS in 2026?
The most cost-effective SaaS stacks in 2026 are Next.js + PostgreSQL + Stripe for startups, and Laravel or Django for teams with PHP/Python expertise. Cloud costs start at $20–$50/month for early-stage apps and scale to $200–$2,000/month at 10,000+ users.
How long does it take to build a SaaS product?
A lean SaaS MVP takes 8–16 weeks. A full-featured SaaS with team management, billing, analytics, and integrations takes 4–8 months. Complex enterprise SaaS with multi-tenancy and compliance can take 9–18 months.
What are the ongoing costs of running a SaaS?
Monthly SaaS infrastructure costs include hosting ($20–$500/month depending on scale), domain and SSL ($15/year), email service ($20–$100/month), error monitoring ($10–$50/month), and payment processing fees (2.9% + $0.30 per transaction via Stripe).
Should I hire a freelancer or agency to build my SaaS?
Freelancers cost 40–60% less and work well for MVPs and straightforward SaaS products. Agencies bring team depth, project management, and faster delivery but at 2–3x the cost. For a first version under $20,000, a senior freelancer is usually the best fit.
How much does it cost to build a micro-SaaS?
A micro-SaaS — a narrow, single-purpose subscription tool run by a solo founder — costs $5,000–$15,000 to build in 2026, or $500–$2,000 in platform fees if you ship it no-code on Bubble first. Keep the scope to authentication, one core feature, and Stripe billing; infrastructure stays under $50/month until you pass a few hundred users.
How much does it cost to add subscription billing to a SaaS?
Adding Stripe subscription billing to a SaaS costs $1,500–$4,000 in development — plans, checkout, webhooks, upgrades, downgrades, and failed-payment handling. Stripe itself charges 2.9% + $0.30 per successful US card charge with no monthly fee. Usage-based or metered billing adds another $2,000–$5,000 because every event has to be counted and reconciled.
How much does it cost to build a B2B SaaS?
A B2B SaaS costs more than a B2C tool because of team accounts, role-based permissions, SSO, and audit logs. A B2B MVP runs $15,000–$40,000, and a full product with multi-tenancy and compliance work reaches $40,000–$120,000+. The enterprise features buyers demand — SSO, SOC 2 readiness, admin controls — are where 30–40% of the budget goes.
