Most MVPs do not go over budget because of code. They go over because the scope never stopped growing. Here are real market figures, a realistic timeline, and the decisions that decide both.
Founders usually ask two questions on a first call: how much, and how long. The honest answer to both is the same. It depends on how many things the first version tries to prove. This guide gives you real market figures, a realistic week-by-week timeline, and the handful of decisions that move both numbers far more than the choice of agency or framework.
How much does it cost to build an MVP?
An MVP typically costs from the low five figures up to around $100,000, depending on how many user journeys it covers, whether it runs on the web, mobile or both, and where the team is based. Pricing pages we reviewed in October 2026 put one UK agency's MVP build at £15,000 to £50,000 and a larger app firm's MVP tier at $50,000 to $100,000.
Narrow web app MVPs can come in lower. An India-based firm's pricing guide listed an early-stage web app with login, one core workflow and a basic dashboard from $5,000 upwards. The spread is wide because "MVP" covers everything from a single-screen tool to a two-sided marketplace with apps on both stores.
Published MVP price ranges
Very few firms publish prices, so the ones that do are worth reading together. These are the figures we found on agency and developer pricing pages in October 2026. Treat them as the spread of the market, not a quote.
| Where the figure came from | Scope described | Range published |
|---|---|---|
| An India-based development firm's pricing guide | Early-stage web app: login, core workflow, admin panel, basic dashboard | $5,000 to $15,000 and up |
| The same India-based firm | Business web app with user roles, integrations and notifications | $15,000 to $30,000 and up |
| A UK mobile app agency | Simple apps, which it describes as best suited for MVPs and internal tools | £15,000 to £25,000 |
| A UK app development agency | A focused MVP build, after discovery and design | £15,000 to £50,000 |
| A large mobile app development firm | MVP with core features to validate business value | $50,000 to $100,000 |
Notice what separates the rows: scope and location, not technology. A web app with one workflow and an app on two stores with several user types are both called MVPs. They are very different projects.
SaaS MVP development cost: what moves the number
These are the decisions that decide where your MVP lands in that table. Most of them are product decisions, which means most of them are yours. A good SaaS MVP development company will walk through each one with you before quoting.
| Decision | Lean option | Heavier option |
|---|---|---|
| Who uses it | One type of user | Separate buyer, seller and admin sides, each with its own screens |
| Where it runs | A web app in the browser | iOS and Android apps, plus the web |
| How people pay | A single plan through Stripe checkout | Trials, seats, usage billing, coupons and invoicing |
| Accounts | Email sign-in for individuals | Teams, workspaces, invitations and single sign-on |
| Admin tools | A simple internal view, or none at launch | Full back office with reports, exports and user management |
| Integrations | None, or one well-documented API | Several third-party systems you do not control |
| AI features | A single model call for one task | Answers drawn from your own documents, with sources and guardrails |
| Data rules | Ordinary personal data | Health, financial or children's data with extra compliance work |
Every row on the right is legitimate. The question is whether it has to be in version one. Usually it does not, and the founders who accept that launch sooner and spend less.
MVP cost by phase
Cost builds up across four phases. One UK agency published phase-level figures, which give a useful shape even if your project sits elsewhere in the market:
| Phase | What happens | Published range |
|---|---|---|
| Discovery | Users, problem, the journey to prove, written scope | £3,000 to £10,000, over one to two weeks |
| Design and prototype | Clickable design of the core flow, tested with target users | £3,000 to £10,000 |
| Proof of concept (optional) | A technical spike to prove something risky can work | £8,000 to £15,000, over two to four weeks |
| MVP build | The working product, launched to real users | £15,000 to £50,000, over eight to sixteen weeks |
| Support and growth | Fixes, small features and the next round of decisions | £1,000 to £5,000 a month |
Two lessons sit in that table. Discovery and design are the cheapest places to change your mind. And the bill does not stop at launch, so keep some budget back for the weeks after real users arrive.
How long does it take to build an MVP?
Most focused MVPs take eight to fourteen weeks from the start of discovery to launch. A single web app with one core journey sits at the shorter end. Separate user roles, apps on both stores, complex billing or AI features push it longer.
That matches what others publish: one UK agency quoted eight to sixteen weeks for a focused MVP, and a product studio's homepage put kickoff to launch at two to three months. Here is how a twelve-week plan usually breaks down:
| Weeks | Stage | What you should have at the end |
|---|---|---|
| 1 to 2 | Discovery | A written scope, the one journey to prove, and a list of what waits |
| 2 to 4 | Prototype and testing | A clickable flow that five or six target users have tried |
| 4 to 11 | Build in weekly sprints | A working preview you can use every week, with analytics wired in |
| 11 to 12 | Launch | Go-live or app store submission, error tracking and a first user review |
App store review adds days you cannot fully control, so mobile MVPs need slack at the end. Web MVPs can launch the day they are ready, which is one reason we often recommend starting there.
The MVP development process, step by step
The order matters more than the methodology name on the proposal. This is the sequence that keeps an MVP small and on time:
- Write down the riskiest assumption. Usually it is that a particular person will pay to solve a particular problem.
- Choose the single journey that tests it, from sign-up to the moment the user gets value.
- List every other feature, then move each one to a later version unless the journey breaks without it.
- Prototype the journey and put it in front of real target users before writing production code.
- Build in weekly sprints, with a preview you can click through yourself every Friday.
- Launch to a small group first, watch what they do, and let that decide version two.
Our MVP development services follow this order, with a fixed scope and quote agreed at the end of discovery so the price is known before the build begins.
MVP development for startups: what to leave out
Cutting is the skill. These are the features founders most often want in version one that can almost always wait:
- A full admin panel. You can run early operations from a database view and a spreadsheet.
- Several pricing tiers. One plan proves willingness to pay.
- Native apps on both stores, when a web app would test the same idea.
- Social sign-in, notification settings, dark mode and profile customisation.
- Automations that a person can do by hand for the first fifty customers.
That last one deserves a word. Doing things manually behind the scenes for early users is cheap, teaches you the real process, and tells you exactly what to automate later. Our guide on how to automate your business covers when that switch is worth making.
Web app, mobile app or both?
Start with the web unless the idea depends on the phone: the camera, location, push notifications, offline use or a daily habit. A web app needs no store approval, updates instantly, and can be found in search. If you build it on Next.js, our breakdown of what a Next.js website costs covers the web side in more detail.
When mobile does matter, one cross-platform codebase keeps the cost close to a single build rather than two. React Native app development gives you iOS and Android from shared code, which is usually the right trade for an MVP.
What makes MVPs late and over budget
- Scope that keeps growing after the quote, one reasonable request at a time.
- Slow decisions. A question that waits a week for an answer costs a week.
- Copy, images and data that arrive after the screens that need them.
- Third-party APIs that behave differently from their documentation.
- Building for scale you do not have yet, such as microservices for a hundred users.
- No single person on the founder side who can say yes or no.
Most of these are not technical. A fixed scope in writing, a weekly preview and one decision-maker on your side prevent nearly all of them.
Agency, freelancer or in-house team?
A freelancer is cheapest and fine for a narrow web app, provided you can manage the project and accept the risk of one person. An in-house team makes sense once you have funding and a product worth years of work, but hiring takes months you may not have before you know the idea works.
An agency sits between the two: design, build, testing and launch from one team, a fixed price, and no hiring. The things to check are who actually writes the code, whether you own the repository and accounts from day one, and whether they will tell you to cut features rather than quote for all of them.
What building our own product taught us
DigiSafe is our own product: a free, end-to-end encrypted document vault with a document scanner, a number reader, expiring watermarked share links and offline access behind one PIN. It is built on Next.js and installs on Android, iPhone and desktop.
Building and running it ourselves means the trade-offs we recommend to founders are ones we have made with our own time. One installable app across phone and desktop. A short list of features that each earn their place. Privacy shown in the interface rather than promised in a paragraph.

FAQ
Frequently asked questions
A minimum viable product is the smallest working version of a product that real users can try, and ideally pay for. It exists to test the riskiest assumption behind the idea, usually that a specific group of people has a problem painful enough to pay to solve. It is not a prototype or a demo. It runs on real data, with real accounts, and it is built to be extended rather than thrown away.
Sometimes. A narrow web app with one user type, sign-in, a single core workflow and a basic dashboard can come in at that level, and one India-based firm's pricing guide we reviewed listed early-stage web apps from $5,000 upwards. Mobile apps on both stores, payments with several plans, or integrations with outside systems usually push the total higher. Cutting scope saves more than haggling over rates.
No-code tools are a good way to test demand quickly, especially for internal tools, simple marketplaces and form-driven products. They become a problem when you need custom logic, better performance, data you control, or a product investors will judge on its technology. Many founders validate with no-code and rebuild properly once paying users arrive, which is a reasonable plan if you expect the rebuild.
As few as it takes to complete one valuable journey from start to finish. For most products that means sign-up, the core action and whatever lets the user see the result, plus payment if willingness to pay is what you are testing. A useful test for any other feature: if the journey still works without it, it belongs in version two. Most first lists can lose half their items.
A prototype is a clickable design that shows how the product will work, with no real code behind it. A proof of concept is a small technical experiment that proves something difficult can be built, such as an integration or an AI feature. An MVP is a working product launched to real users. Many projects use all three in order, each answering a different question.
Plan for hosting, third-party services such as email, analytics and payments, and developer time for fixes and the next features. One UK agency we reviewed published support and growth retainers of £1,000 to £5,000 a month. Your own number depends on traffic and how fast you want to move. The first weeks after launch usually bring the most changes, so keep budget back for them.
Not if it is built properly. A well-structured MVP with clean data models, tests on the parts that handle money and a proper deploy pipeline grows into the full product. Rebuilds usually happen when the first version was made with no-code tools, by a team that cut corners on structure, or for a product that changed direction entirely after launch. Ask how the code will handle version two before you sign.
Not to build it, but you need someone you trust to make technical decisions. Many founders work with an agency for the first version, then hire a technical lead once the product shows traction. What matters is that you own the code, the accounts and the documentation from the start, so a future co-founder or in-house team can take over without depending on whoever built it.
