MVP Development Cost in 2026: What a First Version Really Costs

The most expensive MVP is the one that takes six months.

Not because six months of engineering costs a lot, though it does. Because for six months nobody outside the team uses it. Every feature in it is a guess, and by the time real customers arrive, the money that should have paid for learning from them has been spent building things they didn't ask for.

So this article is about two numbers: what an MVP costs, and how small it should be. They're the same question.

The short answer

From our cost estimator, which every price on our site comes from:

First version of…	Typical range	Timeline
An e-commerce store	$12,500 to $20,000	6 to 9 weeks
A SaaS product	$12,500 to $20,500	6 to 9 weeks
A mobile app with backend and admin	$13,000 to $21,000	6 to 9 weeks
A learning platform	$14,500 to $23,500	6 to 9 weeks
A two-sided marketplace	$19,500 to $31,500	8 to 11 weeks

Each includes an admin panel so you can run the product without us, and user accounts, because almost every product needs them. The marketplace costs more for a simple reason: it has two kinds of user, buyers and sellers, and each needs its own side of the app.

How we arrive at those numbers

We estimate the hours a traditional team would need, including design, testing and project management. We take off 35%, because a team of AI agents does the repetitive part of the work: forms, lists, API endpoints, tests, documentation. Then we price the rest at a blended $25 to $35 an hour. A senior engineer owns the architecture and reviews every release. I've written about how that process works.

The 35% is real on an MVP, because an MVP is mostly the repetitive parts. It doesn't apply to the hard part, which is deciding what goes in.

What actually goes in a first version

Here's the test we use in the first week: what will a customer use, or pay for, in week one? That's the MVP. Everything else is a list for later.

For most products, that comes down to four things:

1. Accounts. People sign up and sign in.
2. The one workflow. The thing the product exists to do. For OpenInterview.me it's turning a resume into a profile a candidate can share. For a booking app it's booking. Only one.
3. Payments, if money changes hands. If your business model is "customers pay", find out on day one whether they will.
4. An admin screen. So you can see users, fix a mistake and run the thing without a developer on call.

That's usually enough to learn whether the idea works. It's also, conveniently, what fits in six to nine weeks.

What can wait for version two

These are the things founders most often ask for in an MVP, and the version we usually suggest instead.

Often asked for	What to do instead
A web app and a mobile app	Start with the one your first customers will actually open
Every type of user and role	Build for the user who pays; add the others when they show up
Custom reports and dashboards	Export to CSV; build dashboards once you know which numbers matter
Integrations with every tool	Connect the one system the workflow can't run without
A recommendation engine or AI everywhere	One AI feature that does a real job, if any
Polished animations and onboarding tours	Clean, fast screens; delight comes after people stay

None of these are bad ideas. They're version-two ideas. Each one you move out of the MVP saves build time, and brings the day real users tell you what's missing a little closer.

What you should never cut

There's a cheap way to build an MVP that becomes very expensive later, and we've cleaned up enough of them to know.

The data model. How customers, orders, accounts and companies relate to each other. If an MVP works, it becomes the product, and changing the data model under paying users means migrating real data, which is the most expensive kind of rework there is.

Security on the server. Permissions checked on the server for every request, no secret keys in the browser, strict database access. A prototype that skips these is a data leak waiting for its first curious user. If your first version was generated with an AI tool, read what to check before launching it.

Payments done properly. If you take money, take it once. OpenInterview.me came to us as a prototype that couldn't safely take payments; the fix was an idempotent Stripe flow that records each payment exactly once, even when a customer double-clicks.

Deployment and backups. The product should deploy from a repository you own to a cloud account you own, with backups you've seen restored. That costs very little on day one and is miserable to add after an outage.

Cut features freely. Don't cut foundations.

The costs nobody puts in the MVP budget

• Hosting and services. Usually small at the start: a server, a database, email sending, file storage.
• Third-party fees. Payment providers take a percentage of each transaction; app stores take a commission on digital sales inside apps.
• Version two. If the MVP works, you'll want to build more, quickly. Keep some of the budget for the weeks after launch, when you know what users actually do. That's the most valuable building you'll ever pay for.

Fixed price, or not?

For an MVP with a clear scope, a fixed price works well, and it's what we usually suggest for a first version. It forces the hard conversation about what's in and what's out before work starts, which is exactly the conversation an MVP needs.

Where scope is still moving, a monthly team or hourly work fits better, because you'll want to change direction as you learn. The written plan we send after a first call says which we'd recommend and why.

Common questions

How much does an MVP cost in 2026? For the products above, typically $12,500 to $31,500 over six to eleven weeks with AI-assisted delivery. A single-sided SaaS or store sits at the lower end, a two-sided marketplace at the upper end.

How long does it take to build an MVP? Six to nine weeks for most first versions, eight to eleven for a marketplace, with a working demo every week so you can steer it.

Should my MVP be a web app or a mobile app? Whichever your first customers will open. Business tools usually start on the web; consumer products people use on the go often start on mobile. With Flutter or React Native, one mobile codebase covers both iOS and Android.

Will the MVP have to be rebuilt later? It shouldn't, if the foundations are right. Keep the scope small, but build the data model, security, payments and deployment properly from the start.

Who owns the code? You should, from the first commit, in your own repository and cloud account. If a quote doesn't say so, ask.
