Flutter app development cost depends on what you're building: a focused MVP, a polished consumer app, a migration from native/React Native, or an enterprise product are four very different budgets. Because Flutter ships one codebase to both iOS and Android, it typically costs 30–50% less than building two native apps. This guide breaks down realistic 2026 ranges, what moves the number, and how to get a fixed quote.

Flutter development cost ranges by project type
- Codebase / performance audit: $2,500 – $8,000 (1–2 weeks)
- Scoped MVP (auth + one core workflow + backend): $15,000 – $40,000 (6–10 weeks)
- Polished consumer app (payments, chat, maps): $35,000 – $80,000 (12–20 weeks)
- Migration from React Native / native to Flutter: $25,000 – $70,000 (8–16 weeks)
- Enterprise / multi-module app: $80,000 – $200,000+ (5–9 months)
- Dedicated Flutter engineer (monthly): $4,500 – $12,000 per senior FTE
What drives Flutter project cost the most
1. Feature complexity
A form-and-list business app is predictable. Payments, real-time chat, maps, offline sync, video, or Bluetooth each add integration and QA time — typically $2,500–$10,000 per major capability depending on edge cases.
2. Number of platforms
iOS + Android from one codebase is the baseline. Adding Flutter web or desktop targets increases QA surface, but sharing code keeps the incremental cost far below a separate build.
3. Backend scope
The app is only half the product. Auth, APIs, an operator admin, and third-party integrations add cost. Building the app and backend with one team avoids expensive contract mismatches.
4. Inherited code state
Greenfield Flutter is predictable. A stalled or messy inherited app needs an audit before estimates hold. Rescue projects should budget discovery before feature sprints.
