How Much Does It Cost to Build a Flutter App in 2026?

“How much will my app cost?” is the first question almost every founder asks us, and the honest answer is: it depends on scope far more than on technology. Flutter lowers the bill because one codebase ships to iOS, Android and the web, but the number on your quote is still set by what the app has to do. This guide breaks down where the money goes so you can budget with confidence.

Why Flutter is usually cheaper than two native apps

A native approach means one team writing Swift for iOS and another writing Kotlin for Android, then keeping two codebases in sync for every feature and bug fix. Flutter replaces that with a single Dart codebase and a shared UI layer. You design once, build once and test most logic once.

• One codebase for iOS, Android and web instead of two or three.
• One team to brief, manage and pay.
• Features ship to every platform on the same day.
• Lower long-term maintenance, because fixes land everywhere at once.

What actually drives the cost

Two apps can both be “a marketplace” and differ in price by ten times. These are the factors that move the number most:

• Number of screens and user roles (a buyer app is cheaper than buyer + seller + admin).
• Backend complexity: simple data storage versus payments, real-time chat, maps or matching logic.
• Third-party integrations such as payment gateways, KYC, maps, analytics and push notifications.
• Design depth: a clean UI kit versus a custom design system with motion.
• Compliance needs, especially for fintech, health and anything handling money or personal data.
• An admin dashboard or web app alongside the mobile app.

Typical budget ranges

Every quote we give is scoped individually after a call, but founders find a rough guide useful. These are the bands we usually work in:

• $1K – $5K: a focused prototype or small single-purpose app with a light backend.
• $5K – $10K: a production MVP with accounts, a real backend, payments or notifications.
• $10K – $25K+: multi-role products, marketplaces, fintech and apps with a web dashboard.

Costs founders forget to budget for

• Store accounts: the Apple Developer Program is $99 per year; a Google Play developer account is a one-time $25.
• Hosting, databases and third-party APIs, which grow with your user count.
• Maintenance after launch: OS updates, store policy changes and bug fixes.
• Marketing and user acquisition, which often costs more than the build itself.

How to get an accurate quote

Vague briefs get vague prices. Before you talk to any agency, write down who the users are, the three or four things they must be able to do in version one, and any integrations you already know you need. A good partner will then turn that into a fixed scope, a timeline and a milestone-based price — and tell you which features to leave for later.
