What it actually costs to build a SaaS in 2026.
In 2026: a development agency runs $50K–250K to build a SaaS MVP, a freelancer $15K–60K, a self-assembled no-code stack $100–500/month plus your weekends, and dedicated AI SaaS platforms $25–100/month all-in. The invoice is only the entry price, maintenance typically adds 15–20% of the build cost every year, which is what makes owned code expensive and operated platforms cheap.
How much does it cost to have a SaaS built by an agency or freelancer?
Agencies quote $50K–250K for a subscription product MVP, over 3–6 months. Freelancers land at $15K–60K with more variance and more of your own project management. Both are legitimate paths, for funded teams with revenue certainty.
The number that surprises founders is the second year: software you own needs updates, security patches, and changes, typically 15–20% of the original build cost annually, or a $100+/hour relationship you maintain forever. The build is the down payment; maintenance is the mortgage.
What does a self-assembled no-code stack cost?
The tools look cheap: a builder ($30–130/month), payments plumbing, auth, email ($20–50/month), hosting and databases. Realistic total: $100–500/month by launch, plus the unbudgeted line, which is you as the systems integrator. Every tool boundary (builder↔payments, payments↔email) is yours to duct-tape and re-duct-tape when a vendor changes their API.
That stack also means five vendor relationships, five status pages, and five support queues when subscription proration goes wrong across two of them at once.
What do AI SaaS platforms cost?
Dedicated platforms run $25–100/month, all-in, building, hosting, payments, email, and upgrades operated by one vendor. On Stencil that's $25/month for Pro (see /pricing), free to start, with the money-moving infrastructure shared, audited, and deterministic across every business on the platform.
The structural difference isn't the sticker price, it's that maintenance rounds to zero for you, because the platform maintains itself for everyone at once. The 15–20%-per-year mortgage simply isn't in the model.
Which option should you choose?
- 1Funded, with unusual technical requirements: an agency or your own engineers, flexibility is worth the mortgage.
- 2Technical yourself, or hiring a developer anyway: AI code generators speed them up honestly.
- 3Non-technical founder building a subscription business: a dedicated SaaS platform, lowest cost, and the only option where operations aren't your second job.
- 4Whichever you pick, budget for year two on day one. That's where the options actually differ.
Quick answers.
Why do agency quotes vary so wildly?
Scope and geography. The same MVP is $40K from a small offshore team and $250K from a US product studio, and the honest answer is that for a v1, the cheaper build usually tests the business just as well.
What's the cheapest way to validate a SaaS idea?
Free tier of a SaaS platform plus a warm list of 200 people. Total cost: $0 and two weeks. Validation is about their money, not yours.
Are there hidden costs on platforms like Stencil?
The plan price is the stack: hosting, payments infrastructure, and email included; payment processors take their standard per-transaction cut wherever you build. What you're not paying: the developer, the vendor sprawl, and the year-two mortgage.
