How much does it cost to build a SaaS MVP in 2026?

It's the first question almost every founder asks us - and most answers online are useless: either a vague "it depends" or a suspiciously precise number with nothing behind it. Here's how SaaS MVP pricing actually works in 2026, so you can budget with your eyes open.

The short version

A focused SaaS MVP - one core workflow, clean authentication, billing, and a real (not prototype) backend - is a few months of build. Simple internal tools sit at the lower end; anything with multi-tenancy, heavy integrations or AI features sits higher. The honest answer is a range, and the range is set by the decisions below.

What actually moves the price

• Scope. Every "while we're at it" feature is more design, build, test and maintenance. The cheapest MVP is the one that does one thing people will pay for.
• Multi-tenancy and security. Building true tenant isolation and SOC 2-aware controls up front costs more than a single-tenant shortcut - but retrofitting them later costs far more.
• Integrations. Each third-party system (payments, CRM, e-sign) is real work. Two integrations is a different project from ten.
• AI features. A grounded RAG feature or an agent with evals and guardrails is engineering, not a prompt - budget for it accordingly.
• Design. A bespoke design system costs more than a templated UI, and it's worth it once you're selling to enterprises.

The Year-1 costs founders forget

The build quote is only part of the picture. Budget for these from day one, or they'll surprise you in month three:

• Hosting and infrastructure - scales with usage.
• Maintenance - plan for roughly 15-20% of the build cost per year for fixes, updates and small features.
• Security and compliance - monitoring, and the work to pass a customer's security review.
• Support - someone has to answer when something breaks.

How to spend less without cutting corners

• Cut scope, not quality. Ship one workflow that works, then expand on real usage instead of guesses.
• Decide the expensive-to-change things early - tenancy, data model, auth - so you don't pay to rip them out later.
• Get a fixed scope and timeline before you start, so the cost can't drift silently.
