Flutter app development cost

When it comes to mobile app development, cost is often one of the key concerns for startup founders and decision-makers. Flutter has become a popular choice for cross-platform development because it allows businesses to build iOS and Android apps with a shared codebase, potentially reducing duplicated development effort.

In our experience, Flutter app development costs typically start from around $25,000, while the final budget depends on product complexity, features, design requirements, backend development, integrations, security, and the development team.

So, how much does Flutter app development cost for different types of projects, and what factors have the biggest impact on the budget? In this guide, we break down Flutter app development costs, key pricing factors, real project estimates, and practical ways to optimize your budget.

Why consider Flutter framework for your app development?

Flutter is an open-source framework by Google that allows developers to build applications for iOS and Android from a shared codebase. It has grown into a mature cross-platform technology used by startups, established businesses, and development teams worldwide. According to Google, Flutter now has more than 1.5 million monthly developers, a 50% increase in one year.

What’s in it for developers?

Flutter allows developers to reuse much of the same code across iOS and Android instead of maintaining two completely separate mobile codebases. It also provides hot reload, which lets developers see many code and UI changes in a running application without restarting it from scratch. This can make development, testing, and iteration more efficient.

What's in it for business owners?

For businesses, a shared codebase can reduce duplicated development and maintenance effort across iOS and Android and simplify team coordination. Flutter can therefore be a cost-efficient option when both platforms need to be launched and supported, while still allowing teams to build custom user interfaces and performant mobile experiences.

Key factors influencing the Flutter app development cost

Each Flutter project is unique and has its own requirements, so it is difficult to name a precise development cost upfront. However, there are several key factors that have the biggest impact on the final budget.

1. Project complexity and size

In terms of complexity, Flutter mobile apps can generally be divided into simple, medium, and complex products. The more features, user roles, integrations, and custom logic your app requires, the more development and testing effort will be needed.

In our experience, a simple Flutter project may take around 2 months, a medium-complexity app around 4 months, while a more complex product can require 4–6 months or longer.

A relatively simple app with basic functionality will usually require less development effort. Features such as payment gateway integrations, real-time functionality, advanced workflows, or AI-powered capabilities like voice assistants and image recognition increase both development time and cost.

2. UX/UI design

UX/UI design is the cover that influences the user's first impression of your app, so its importance can’t be underestimated. UX design ensures a smooth user journey within your app, while UI design makes the experience aesthetically pleasing. By providing customers with a unique in-app experience and personalized approach, businesses stand out from the competition.

For example, our recent client even had a major objective to create a Flutter-based app for job search that would be extremely intuitive yet simple, all while staying within their allocated budget for app design cost. As a result, the app has become the best business app in App Store within the first month after the release.

Though a well-thought-out Flutter app design can “eat up” around 20% of the whole development budget, this is worth the cost.

The most design-demanding apps by industry include gaming (e.g., for mobile game monetization), fitness, and e-learning, to name a few. These types of applications often use advanced animations and complex graphic solutions. To delve deeper, read how to develop a fitness app.

3. Security

Security is another important factor that can influence Flutter app development cost. Applications that process sensitive personal, financial, or healthcare data usually require stronger security measures, additional testing, and sometimes industry-specific compliance requirements.

The level of security depends heavily on the product domain. A simple utility app may require relatively standard protection, while fintech, healthcare, or e-commerce applications may need secure authentication, encrypted data storage and transmission, access controls, payment security, audit logging, and other safeguards.

These requirements should be considered early in the project, as stronger security standards can affect architecture, development effort, testing, and the overall budget.

4. Post-release support

Mobile app development does not end at launch. A production app requires ongoing maintenance to remain secure, stable, compatible with new OS versions, and aligned with changing user expectations.

Post-release work may include bug fixes, Flutter and dependency updates, performance improvements, OS compatibility updates, monitoring, security patches, and incremental product improvements.

As a general planning benchmark, ongoing maintenance and support may require around 15–20% of the initial development budget per year, although the actual amount depends on the product's complexity and how actively it evolves after launch.

5. Team location

When searching for a team offering Flutter app development services, you should keep in mind that costs greatly vary by location. As of today, average hourly rates of Flutter development companies start from $15-20 in Asian and African regions and can reach $200. Traditionally, the USA, Australia, and Canada are the most costly regions in terms of hiring.

Nowadays, numerous startups tend to hire experts in European countries like Poland and Lithuania, as IT outsourcing has remarkably scaled there. Moreover, the team is not limited to Flutter developers only – you will need other specialists like designers, testers, and project managers. That’s why opting for European expertise at compatible prices seems to be the best choice.

What else may affect the Flutter app development cost?

Above we have listed the most basic factors that form the Flutter price, but here are a couple of bonus ones for those who have a complex Flutter project on the agenda.

Custom integrations

In fact, API integrations are a nice way out when you don’t want to invest much time and resources on writing code. There’re thousands of ready-made APIs available on the market, but they may not always be enough to meet your business requirements. In some cases, you need a unique well-tailored solution. And that’s when custom integrations come to the rescue.

Though custom integrations empower businesses to achieve better app performance and interaction with other corporate systems, in the context of the Flutter pricing, they can cost a pretty penny.

Backend development

Unfortunately, Flutter has no default backend solution since it powers only the frontend side. Hence, you need to come up with a solid backend stack that would guarantee the smooth operation of your Flutter application. It is especially important for messengers, social networks, and similar apps that have complex structures and undergo high loads. A well-tuned backend is essential to ensure uninterrupted real-time data exchange and storage of large amounts of data.

The average cost of Flutter app development

Let’s do some math on calculating average costs for the example of a small and simple app. It’s important to remember that the development of a convenient and functional Flutter mobile application requires a multifaceted approach and deep expertise. In addition to Flutter developers, the team should also include a backend developer, designer, QA, and project manager.

Let's take a look at the timeframes needed to develop key Flutter app features on the example of a real case – a mobile application for making medical appointments.

Now let’s calculate the total cost:

Flutter development: 202 * $50 = $10,100 Design: 48 * $45 = $2,160 Backend development: 172 * $50 = $8,600

In summation, we get $20,860 only for design and development.

Additionally, we should include the work of a project manager who controls the whole process (160 * $50 = $8,000), and a QA tester who is responsible for the bug-free app performance (160 * $40 = $6,400).

To sum it up, you should invest around $35,260 for a similar simple Flutter-based app.

Though these calculations don’t cover post-release maintenance, compared to native app development, creating a Flutter app is 30%-40% less costly.

How to reduce the Flutter app development cost

Careful planning can help you control the budget and avoid unnecessary development costs. Here are several practical ways to reduce Flutter app development cost without compromising the core value of your product.

Set clear project requirements

The more clearly you define the requirements and expectations for the final product, the easier it is to avoid scope changes, unnecessary features, and potential cost overruns during development.

One effective way to achieve this is through the discovery phase. For example, during one of our healthcare projects, discovery helped us reduce the initial development budget by 25% and avoid unnecessary iterations during product development.

Proper preliminary planning and research can help define your product objectives, target users, monetization strategy, technology stack, and essential features before development begins. For more guidance, check our article on the discovery phase.

Select only main features

Another way to keep development costs under control is to prioritize the features that are essential for the first release.

Trying to launch a fully featured product from day one can significantly increase both the budget and development timeline. An MVP, or Minimum Viable Product, allows you to focus on the core functionality needed to validate the product idea and gather feedback from real users.

Once the initial version is validated, additional functionality can be introduced gradually based on user needs, product data, and business priorities. This approach helps avoid investing heavily in features before their value has been proven.

Hire a professional outsourcing team

Recruiting an experienced outsourcing team has a number of advantages. In most cases, outsourcing is less expensive than finding in-house staff and implementing an attendance management system or a leave management system, as you can automatically cross off costs on infrastructure and equipment from the expenditure list. Additionally, there’s no need to waste time on long-lasting interviews and onboarding.

In general, outsourcing helps to optimize workflow and improve efficiency. You can hire a well-rehearsed team that specializes in cross-platform development services, that has previously covered many projects together. This means that you won’t face any communication problems inside the team and will be able to focus on your main priorities. All in all, collaborating with an outsourcing team can efficiently cut the Flutter app development cost.

Bottom line

Flutter app development cost depends on your product requirements, complexity, features, integrations, design, and technical architecture. However, by using a shared codebase for iOS and Android, Flutter can help reduce duplicated development effort and make cross-platform development more cost-efficient.
