How much does a Flutter app cost to build?
A Flutter app costs less than the same product built natively for iOS and Android separately, because one codebase ships to both stores. That is the whole point of Flutter, and it is where the savings come from. But "less" is not a number, so here is a straight answer with real ranges, and the handful of things that actually move the price.
The short answer
For a genuine Flutter app (real users, real data, both app stores, not a prototype), the market in 2026 looks roughly like this:
- A simple app, one core job: roughly $15,000 to $30,000. Sign up, do the one thing, pay. A few screens, one or two integrations, a clean design system.
- A standard app, several flows: roughly $30,000 to $60,000. Accounts, content, payments, notifications, a handful of integrations. Where most funded MVPs land.
- A complex app, custom or regulated: roughly $60,000 to $120,000+. Heavy real-time features, AI, hardware, or compliance that shapes the whole architecture.
The single biggest saving Flutter gives you is not on the list above, it is what you avoid: building the same app twice. A native iOS build and a separate native Android build is roughly two teams and close to double the cost. Flutter collapses that into one team and one codebase, which for most founders is the difference between a $60,000 mobile app and a $30,000 one, with no meaningful compromise on how the app feels.
What actually drives a Flutter quote
- Scope: how many core flows. The biggest lever by far. Every extra flow is a line item, not a footnote. The cheapest optimisation in software is cutting scope you did not need.
- Integrations: payments, auth, third-party APIs. Stripe, authentication, maps, messaging. Each one is its own small project with its own edge cases, and each adds to the number.
- Design: system components or fully custom. A product built on a sensible design system is fast. Bespoke everything and custom animation add weeks.
- Backend: new build or existing. A Flutter front end still needs an API behind it. Reusing one you have is cheaper than building it alongside the app.
- AI and real-time features. Live updates, chat, or an LLM feature done properly is engineering, not a plugin, and it is billable.
If you want the deeper breakdown of what moves an app budget in general, our guide on the
cost to build an MVP walks through the same levers with worked examples. And if you are still deciding between frameworks, our Flutter vs React Native comparison covers when each one is the cheaper long-term bet.
The cost that never makes it into the quote
The most expensive way to build a Flutter app is not a high day rate. It is an open-ended, hourly build against a vague spec, where every misunderstanding and every discovered edge case is billed to you. That is how a "$25,000" app quietly becomes a $55,000 one, months late. The framework was never the risk. The pricing model was.
If you want a real number for your app instead of a range for the market, our Flutter app development service gives you one fixed quote in writing within 48 hours from a single scoping call. Prefer to start from the outcome rather than the stack? Our MVP development service scopes, prices and ships the whole product to a launch date you can plan around.
