How Much Does It Cost to Build a SaaS Product in 2026?

The Honest Answer

It depends on scope — but "it depends" is useless if you're trying to plan a budget. Here are real ranges based on what we see in the market, with the assumptions behind each number.

The Three Models

1. Agency (Fastest, Highest Cost)

A specialist agency brings a team — product manager, designer, engineers, QA — and handles the full delivery. You trade cost for speed and predictability.

MVP (3–4 months): $60,000–$150,000 Full product v1 (6–9 months): $150,000–$400,000

What you're paying for: senior talent, proven processes, no hiring overhead, no management tax on your side. The right choice when time-to-market is a competitive advantage and you can't afford a 6-month hiring process.

2. Freelancers (Flexible, Variable)

Individual contractors hired per-discipline — one for design, one for frontend, one for backend. You manage the coordination.

MVP: $30,000–$90,000 Full product v1: $80,000–$200,000

The range is wide because freelancer quality varies enormously. Senior freelancers charging $150–200/hr deliver agency-quality output. Junior freelancers at $40–60/hr require significant oversight and often produce more rework.

The hidden cost is your time — coordinating three freelancers takes 5–10 hours per week of founder/PM time.

3. In-House Team (Slowest to Start, Cheapest at Scale)

Hiring full-time engineers in-house makes sense once you're past product-market fit and have a stable roadmap.

Time to first hire (senior Next.js engineer): 2–4 months Annual cost (fully loaded): $180,000–$280,000 per engineer in major US cities

At two engineers plus a designer, your in-house capacity costs $500,000–$700,000 per year. This breaks even against an agency only if you sustain high output over multiple years.

What Drives Cost

Scope is the biggest variable

A simple SaaS with authentication, a dashboard, and Stripe billing is a very different project from a marketplace with matching algorithms, real-time features, and native mobile apps.

Low scope (MVP with 5–8 features): Start at $40k agency Medium scope (complete product, 15–20 features): $120k–$250k agency High scope (complex marketplace or platform): $300k–$600k+

Design quality

Generic UI templates cost $0 extra but look like every other SaaS product. Custom design systems with user research take 4–8 weeks and add $20,000–$50,000. The ROI on good design is real — conversion rates on well-designed products are measurably higher.

Integrations

Every third-party integration (Stripe, Twilio, Salesforce, HubSpot, enterprise SSO) adds scope. Budget $5,000–$15,000 per non-trivial integration for discovery, implementation, and testing.

Compliance

HIPAA, SOC 2, or PCI-DSS requirements add significant architecture overhead and documentation work. Add $30,000–$80,000 to any project that needs formal compliance certification.

A Realistic MVP Budget

For a typical B2B SaaS MVP (authentication, multi-tenancy, core feature, Stripe billing, basic dashboard):

This is the agency model with senior talent. Freelancers can get to $40,000–$80,000 for the same scope with more founder involvement.

What's Not Included

The numbers above cover development only. Add to your budget:

• Infrastructure: Vercel Pro ($20/mo), database (Supabase Pro ~$25/mo), CDN — negligible at MVP stage
• Third-party services: Auth0/Clerk ($0–$100/mo at early scale), email (Resend $20/mo), analytics — typically $200–$500/mo total
• Legal: Terms of service, privacy policy, cookie policy — $2,000–$5,000 with a tech lawyer
• Marketing site: Often separate from the product — add $10,000–$30,000
• Ongoing maintenance: Budget 15–20% of initial build cost per year for maintenance, dependencies, and minor features

The Build vs Buy Question

Before budgeting custom development, audit what can be bought:

• Auth: Clerk or Auth0 saves 3–4 weeks of build time
• Billing: Stripe + a billing UI library (Lemon Squeezy, etc.)
• Admin dashboard: Retool, Forest Admin for internal tools
• Email: Resend + React Email templates
• Support: Intercom, Crisp for customer support chat

The best SaaS products are 70% bought, 30% built. Your competitive advantage is the core feature — not the authentication flow.

Getting to a Real Number

The only way to get an accurate estimate is to scope the project with a technical partner. A discovery engagement (2–4 weeks, $8,000–$15,000) produces a detailed spec, architecture plan, and delivery timeline — turning an educated guess into a real number.

Skipping discovery to save $10,000 on a $100,000 project is how you end up with a $160,000 project.
