How much does it cost to build an app in 2026?

The cost of having an app built depends heavily on what has to go into it. A simple app in 2026 usually sits between €8,000 and €25,000, a full product with user management, payments and its own back end between €25,000 and €75,000. That range is wide for a reason. It follows from three things: the number of platforms, the complexity of the logic and the pace at which you want to launch. Below you will find the realistic prices and see where your money goes, so you can judge a quote without walking into surprises.

What does it cost to have an app built in 2026?

Budget €8,000 to €25,000 for a first usable version, and €25,000 to €75,000 or more for a full platform. The word "app" covers everything from a digital form to a complete SaaS product, which is why the price lists on comparison sites vary so widely that they tell you very little. You only get an honest price once someone translates your idea into concrete screens, integrations and user roles. That is why at Build More you get a fixed proposal with a price and a date within 24 hours of a first conversation.

Why do the prices vary so much?

Four factors account for most of the cost:

1. Number of platforms. A web app on its own is cheaper than web plus a native app for iPhone and Android.
2. Complexity of the logic. A form is built quickly, while real-time collaboration, scheduling or payments take a lot more work.
3. Integrations. Every connection to your accounting system, ERP or an external service takes time to build and to test.
4. Pace. If you want to go live sooner, we put more people on your project at once, and that raises the price.

Once you know these four, you can already estimate which end of the range an idea falls in.

Web app or native mobile app, which is cheaper?

A web app is almost always the cheapest and fastest start. It runs in the browser, works on every device and is findable straight away through Google and AI search engines. A native app earns its extra cost once you want to work offline, need push notifications or need access to the camera and GPS.

If you are in doubt, start with a web app and build a mobile app on top of the same back end later. That way you pay the native premium only when you really need it.

How much does an MVP cost and what does a full product cost?

An MVP, the first version that does just enough to launch, usually costs €8,000 to €25,000 and goes live at Build More in 4 to 8 weeks. A full product grows from there, feature by feature.

Starting small is also the smartest move financially. According to CB Insights, which examined more than a hundred failed start-ups, 42% stumble over a product that turns out to have no market. These are self-reported post-mortems, so treat it as a signal and not as law. The lesson still stands: spending tens of thousands of euros before you know whether there is demand is the real risk. An MVP buys you that certainty cheaply.

Where exactly does the money go?

Roughly split, your budget goes to the design, the screens the user sees, the back end with database and logic, the integrations with your existing software, testing, and the first weeks after launch. The surprise for many people: the visible screens are rarely the biggest cost. The real work sits in the back end and the integrations, the part the user never sees and that makes everything add up.

How do you keep the costs under control?

A few rules of thumb quickly save you thousands of euros:

1. Keep the scope tight. Build the process that costs the most time or errors today first, and expand only after that.
2. Start with a web app. Faster to launch, cheaper, and usable on every device.
3. Reuse existing building blocks. With Next.js, Astro and Supabase the production-ready foundation is up quickly, so the hours go to your unique functionality.
4. Ask for a fixed proposal with a price and a date, so you never sign up to an open end.

And AI? It speeds up certain steps, though it delivers no magic discount. What AI does and does not save you is covered in this article.
