In 2022, consumers are expected to spend over $156.5 billion on mobile apps via app stores. And by 2023, global mobile app revenues are projected to increase to $935.2 billion.

Founded in 2009, WhatsApp initially had a seed funding of $250,000 to build their application. Though it did not suffice them back then due to the number of users exploding, they still smartly sustained their growth by managing their app development process and the cost involved. Today, it is one of the most used mobile messenger apps worldwide.

This guide examines all the factors that influence app development cost in detail. It also discusses cost breakdown for straightforward calculation, tips to reduce costs, a few ballpark estimates, and examples.

Let’s start with an overview of app development costs today.

App Development Cost in 2021

The cost to develop a mobile app can fall anywhere between $10,000 to $500,000 or even up to $1 million and above, depending on the type, features, and complexity of the app. There is no exact figure for mobile app development cost, but that’s quite a wide range, isn’t it?

Such a huge gap is due to the multitude of factors that affect app development. So how do you calculate the price for your mobile application development?

To simplify, let’s narrow the range by categorizing your mobile app idea based on its complexity, which is the major influencing factor. Determining whether your app is simple, moderately complex, or highly advanced is a good starting point.

To help you understand below is a table that shows the fundamental difference between the complexities of the app. It also illustrates the tentative price range and timeline for developing an app for one platform.

Complexity Simple app Moderate app Advanced app
Cost $10,000- $50,000 $50,000- $200,000 $200,000+
Description Basic features like notifications, database integration, user login, and so on Customized UI/UX features Advanced functionalities like audio/video streaming, real-time synchronization, etc.

Timeline  2-5 months  4-9 months  9+ months

These numbers are average benchmark estimates to give you an idea of costs you’re likely to incur to get started on planning your app development budget. A small app with core features can be developed at lower rates, whereas a complex app with intricate design or a feature-rich enterprise app will be expensive. If you’re building a minimum viable product (MVP), it may cost even less than $10,000, taking only a few weeks to develop depending on the complexity. Also, you’ll need a larger budget if you want to develop a mobile app for both Android and iOS platforms.

However, the overall quotation will fluctuate depending on a myriad of other factors apart from the complexity. We will discuss these factors in detail later. Let’s proceed with the formula for calculating app development cost.

Formula to Calculate App Development Cost

How do you calculate the cost to build an app?

By factoring in the total development time and hourly rates, you can quickly work out a rough estimate. Here’s the simple formula to calculate your app development cost:

app development cost formula

The number of development hours will directly depend on the complexity, size, features, functionality, and design of the app. The hourly rates will depend on your development team set up, whether you hire freelance developers or a dedicated development team. The location of the team also affects the hourly rates as they differ in different countries.

After considering all these influencing factors, the figure will be a lot closer to your actual mobile app development cost. So keep reading to understand the influence of various factors better to ascertain your ideal budget.

Factors Determining the App Development Cost

factors affecting app development cost

The mobile app development process is unique for every project or idea. So the app development cost that a software development company might provide you will be based on several factors. It is based on feasibility, technical requirements, development time, customizations, and so on.

Hence, it is essential to deeply understand the factors that affect the development costs. The major determinants are:

  • Project type
  • Platforms
  • Features
  • Development partner and Engagement model
  • Location of development partner
  • Design complexity
  • App maintenance and other additional costs

Let’s analyze each factor in detail and work towards estimating the development cost step by step.

Number of Platforms and Development Approach

As you start calculating app development cost, the first question you need to answer is what platform to build your app on: Android, iOS, or both. It will also help decide the development approach, whether the app will be built for native or cross-platform.

Android vs. iOS app development cost

If you develop natively for a single platform, there won’t be a massive difference in the development cost for iOS and Android. However, the timeline could differ depending on the complexity of features and functionality to be included. So the cost would be proportional to the number of hours required. But if you’re developing for both platforms individually, it will double the prices. Simultaneously, building on the iOS platform requires following Apple’s strict guidelines and regular maintenance, whereas Android is more flexible. Finally, both Android and iOS development use different SDKs and frameworks, affecting overall costs.

Cross-platform vs. Native app development

cross-platform vs. native app development

Recently, cross-platform development technologies like Flutter, Ionic, and React Native are increasing in popularity in the IT industry. They facilitate the development of apps for multiple platforms with a native-like functionality with a single code base. Such hybrid apps can cut down development costs and time-to-market significantly. It is also easier to maintain apps and update features after release since there are no separate codes.

On the contrary, native development is best suited for high-performance apps or apps with many custom animations or complex UI. Native apps are better optimized for user experience than hybrid apps, making them technically superior. Moreover, they also have greater functionality with hardware and are highly scalable. They use specific toolkits and programming languages such as Swift for iOS and Java or Kotlin for Android apps. Generally, native app development is costlier and requires a higher development timeline.

But what if you want to develop a mobile app for both platforms cost-effectively? Then cross-platform development is the preferred choice, which brings us to our next point.

Pro-tip to reduce cost: For younger startups, it is advisable to target one platform initially. When choosing between platforms, it is vital to consider factors like market share of Android and iOS devices, country-wise prevalence, etc. For instance, Android has twice as many users as iOS, but iOS has a significant market share of around 60% in the USA alone. But globally, Android has more users.

You may also consider releasing both Android and iOS app versions with simple functions. For example, at Simform, we have developed and designed various applications for both Android and iOS platforms within the range of $30,000-$40,000.

Moving on, the next step is to determine the features you will include in your app based on its purpose and function.

App Features and their Complexity

To estimate a more accurate app development cost, the number of features to be implemented in your app is critical as it will affect the development hours most significantly. In addition, more complex features take a longer time to develop than basic ones, increasing the overall cost of development. So, the effective formula will look like this:

App development cost = (Features X Development time) x Hourly rate

While making a list of features you want to include, it is best to consider long-term business goals and go for the ones in the best interest of your target audience.

If needed, developers may use ready-made templates or third-party APIs, which will add extra cost. Even the typical user engagement or authorization features can vary in complexity. Overall, the development and maintenance of highly complex features is more cost-incurring than basic features.

Well then, let’s take a look into some basic and complex features in detail with an approximate time to develop each.

BASIC FEATURES:

  • User login

Login determines the customization of an app according to the user details. Login accessibilities can be provided to users via email or phone, but signing in through social media accounts like Facebook or Twitter is a popular option. Basic implementation of this feature will take 20+ hours. Integrating social login or custom-built login/registration will add to the hours and cost. Moreover, storing the data of users who log in will require another set of maintenance and security features.

  • Navigation

App navigation defines the flow of users and how they perform activities in the app. It includes developing the UI architecture of scrolling, swiping, buttons, icons, menus, and switching screens. It takes 10+ hours to build, but adding customizations like allowing users to change language, switch list view to files, or full width, will require more hours. Also, adding landscape mode will require additional 20 hours to develop and thus, increasing the cost.

  • Chat

Chat or in-app messaging has become an integral feature for apps today. Developing P2P chat will take 50+ hours depending on the functions you’re planning to add. These functions include file transfer, saving or auto-deleting messages, history, offline mode, notifications, emojis, and so on. Group chat may take an additional 80+ hours. These days integrating off-the-shelf chat SDKs is more preferred. While it can add to costs, you may want to compare it with the cost of developing a custom chat module.

  • Search

Search function helps users search inside the app quickly. A basic search function with suggestions will take 15+ hours to complete. But the time and cost depend largely on the scope of indexing and how its algorithm is tailored to retrieve specific information. It also depends on whether you want to add functions like predictive search, filtered search, and so on.

  • Push notification

Push notifications are a must-have in apps today for engaging users and updating them with real-time information. The simplest form can be developed in 15+ hours, but varying notifications with images or action buttons may take longer. Moreover, adding the logic of when to send notifications can take up to 200 developing hours.

COMPLEX FEATURES:

  • Payments integration

Payment functionality is necessary if users are purchasing something within an app. Many in-app payment systems are available such as Google Wallet, Apple Pay, Paypal, or credit cards, which can be directly integrated through payment gateway APIs. Depending on where data is stored, level of PCI compliance, and other such factors, this task can take about 50+ hours or more. In-app purchases for subscriptions or premium services can also be easily included and takes about 30 hours.

  • Geolocation

Geolocation is vital for navigation in mobile apps for food delivery, transportation, traveling, dating, business apps, or locating user devices. It uses GPS and real-time user permissions. It can take up to 32-50 hours to be implemented. Also, integrating Google Maps can take additional 20+ hours.

  • Streaming audio/video 

This feature is quite complex to implement and is used for on-demand apps like Netflix, Hulu, etc. The time and cost of development will depend on the app logic, file format, server setup, processing, and other settings. It can take up to 90+ developing hours.

  • Analytics

Analyzing user activity can provide valuable insights into app performance or issues that can help improve the application. The most basic form of an analytical tool takes 5+ hours to be implemented. It is integrated with services like Google Analytics, Flurry, etc. And, the costs of these services can increase depending on how many user activities you want to track.

  • Offline mode

The offline mode requires a local database on the device for access and storing data. Usually, developers use SQLite to store data in a single file on the device. The development time for this feature is 30+ hours, but it can depend on the amount of data and its storage.

  • Data encryption

Every app demands high security to help secure private data, messaging and to eliminate unauthorized access. Data encryption feature requires a minimum of 20+ hours to be developed. The time and cost also depend on whether encrypted data is text, image, audio, or video.

  • Connectivity with a device

Often apps require hardware features to ensure interoperability with the device’s in-built features. An app may need to access Bluetooth, camera calls, sensors, NFC, etc. Integrating these features will require additional development hours, thereby increasing costs.

  • Multi-Language Support

If your app caters to users from several countries, it should have multi-lingual support. Adding multiple languages will slow down the development process and cost more. But it can extend user engagement boundaries. The cost is affected by the extent to which you want to implement language translations within your application. It also depends on UI adjustments and the scope of data.

Pro-tip to reduce cost: If your budget is limited, you can prioritize the features to fit your range and later improve as per users’ feedback after launching. Also, some unexpected changes in the scope of the project may occur during the development. So it is advisable to highlight essential features you want to include first.

Now, the further step is choosing who will develop your mobile app.

Development Partner, Engagement Model, and their Location

When deciding who will build your app, you can hire freelance developers or a mobile app development agency. You can also hire professionals to extend your existing in-house development team if needed. All these routes have pros and cons associated with them which significantly affect the overall app development cost.

You must choose the right partner depending on the project size and complexity. However, their cost shouldn’t be the only deciding factor. Instead, consider the talent, expertise, and experience of the development team. You can ask them for references and read clients’ feedback on recent projects for other necessary information. The location of the development team also dramatically influences the app development cost.

Let’s have a closer look at all these aspects.

Hiring Freelancers

Hiring freelance app developers is the most cost-effective way to build an app if it isn’t too complex. If you manage to hire a talented freelancer, they can build apps with good quality as developed by an agency at a lesser cost. The hourly rates also drastically differ as per their location. For example, in the USA, the hourly rates of mobile app developers start from $50 per hour, while in India, the rates start from as low as $10 per hour.

But you cannot rely on one person to complete the process. You will need to hire freelancers for all aspects like design, coding, QA, and manage the team yourself. Working with this model may pose certain challenges like communication gaps, limited accountability, and transparency. It can lead to delays and low-quality development which is costlier in the long run.

It is best suited for developing simple or small apps. But if you’re on a tight budget, you can split your project into smaller phases. Also, ensure that you clearly define and convey your requirements.

Hiring App development agency aka Outsourcing

Hiring a mobile app development company to build an app is more advantageous, reliable, and easier. It is costlier but provides faster and quality-assured results. These teams work with deep involvement, discipline, and efficient communication. The agencies ensure projects complete on time, with the desired results, and security which makes it worth the cost.

App development agencies have all the required infrastructure, resources for developing and deploying apps. Their team of highly qualified and experienced professionals will guide you through creating robust, feature-rich apps from the planning to the deployment phase with the best options. Their dedicated team of specialists consists of:

  • Business Analyst
  • UI/UX Designers
  • iOS/Android Developers
  • Quality Assurance Engineer
  • Project Manager

The size and structure of the team will directly affect the development cost, and it should be according to the needs of your project. For example, complex apps will require more work by the designer, hence two or more developers may be required comparatively with basic apps.

The costs charged by the agencies will depend on all the factors we’ve covered above and their location. Also, the cost may be influenced by the engagement model you choose. US-based agencies charge $100-$250 per hour, but if you outsource app development to Indian agencies with the same quality and expertise, it can cost $25-$40 per hour.

Hire Dedicated Remote Developers/Extended Team

If neither of the above models seems ideal for your needs, you can hire dedicated remote developers and add development capacity on demand. The difference between hiring freelance developers and dedicated developers is that a freelancer might be working on several projects at a time which can hinder the quality of work. But a dedicated developer is only working on your project which enhances productivity and quality of work. Also, when dedicated developers are hired from a software development company, you do not have to do the hiring legwork such as vetting candidates, payroll, etc.

Not only developers, but you can also hire dedicated project managers and other required professionals to extend your existing in-house team. An extended team is preferred when you already have established management, processes, and workflow. With a dedicated development team, you get higher security, expertise, and uninterrupted productivity.

Simform has the answer to all your needs whether it is hiring dedicated developers, team extension, or building a project from scratch. Our developers and teams will seamlessly integrate with your culture to build a great product.

Pro-tip to reduce cost: It is cost-effective to have one app development agency take care of both design and development. Furthermore, outsourcing mobile app development or extending your existing team will provide financial benefits as well as access to a larger talent pool.

Cost Breakdown Based on App Development Stages

Now, you’re just one step away from deciphering the final development cost of your app.

A complete app development process is much more than just coding and designing. It has different stages as shown below.

stages of app development

Each stage constitutes a chunk of the total app development cost. Therefore, a comprehensive understanding of the development process will allow you to allocate funding to each stage better. The significant factors we covered earlier mainly pertain to the development stage. So, let’s discuss in detail the cost and time required for each stage.

app development cost breakdown

Business Analysis/Discovery stage

You have a winning mobile app idea, but how do you make an app out of it? This pre-development stage helps your app development vendor know the ins and outs of your app from technical, development, and business perspectives. It is often underestimated, but further development is impossible without it.

A business analyst verifies the business scope of your app, runs the competitor analysis and market research, prepares documentation, app architecture plan, and product backlog. User stories in product backlog help calculate the development budget and delivery time more accurately.

Cost of Business Analysis Phase

  • Can cost anywhere from $1,500 to $10,000+ 
  • Has a timeline of 2-4 weeks
  • Takes 10% of the whole app development budget

 

Design stage

Impressive UI/UX is a must for your app to hook users’ attention. The UI designer gives your app a unique look. And UX designers meticulously develop user experiences after behavior studies to deliver specific results. Depending on the target audience, the design costs fluctuate as per the number of screens, design complexity, and custom visual elements.

If you have a tight budget, prioritize the elements or divert funding from other stages if it’s worth it. Also, it is crucial to have a functional prototype in place before proceeding towards development.

Cost of Design Phase

  • Ranges from a minimum of $2,500 to $10,000
  • Can increase to $25,000-$50,000 or higher for complex apps
  • Has a timeline of 2-6 weeks, depending on complexity
  • Takes 10-15% of total app development cost

Development or coding is the largest function of the whole app development process and significantly influences the overall budget. And of course, its cost depends on various factors which we’ve covered extensively like app complexity, features, platform, development resources, and their location.

Cost of Coding Phase

  • Costs between $10,000-$30,000 and above
  • Can even cost $5,000 or less in some cases.

 

Testing and Deployment stage

Testing, quality assurance, and deployment are crucial to ensure the success of your app development project. Users will drop your app if they face multiple lags or glitches, even though it has good functionality.

QA engineers conduct individual tests for all features and aspects of the app to make it flawless and avoid any issues or bugs post-release. However, app testing is not limited to this stage. It can be carried through the development process to ensure the proper functionality and quality of the app.

There are different testing tools available and the total cost will be affected by the tools used. It will also be influenced by the experience of development in making use of the tools chosen.

Cost of App Testing and Deployment Phase

  • Cost less than $5,000 or within $5,000-$10,000
  • Seldom costs more than $10,000k based on app’s functionality

App Maintenance and Other Hidden Costs

After you’ve built a great app and deployed it comes the phase of maintenance and support. It is vital to keep your users happy and retain them by improving the app according to their changing expectations. It entails implementing necessary updates, new features, bug fixing, and emergency maintenance. It also includes the cost of app infrastructure services like servers, database, and third-party services.

Cost of App Maintenance Phase

  • Costs less than $5000 or $5000-$10,000 annually
  • Takes 10-20% of the original app development budget

Some app development companies also offer free maintenance for a few months after release or at regular intervals. It is better to ensure you benefit from such services and have breathing room in your budget for any hidden costs that you might have overlooked.

Below is a list of maintenance costs, including other hidden expenses you may incur during the app development process, its launch, and post-launch.

  • Cost of App Release:

Google Play Store charges a one-time fee of $25 and the iOS App Store charges $99 per year for releasing an app.

  • Updates:

The time and cost of updates vary depending on the nature and size of the update. For instance, updating a functional aspect can take days and cost around $1000-$2000 based on hourly rates.

  • Bug Fixes:

The cost of bug fixing also depends on the size of the app and the nature of the changes. A quick bug fix in one line of code would not cost much. But if there are too many bugs to be fixed, it can impact the total cost significantly.

  • Hosting:

Hosting app data on a server can cost $20 to $300 per month, depending on the type of data, amount, and type of solution you choose. If you choose to host in the cloud, it may be cheaper with their pay-per-use model. And also, you will need to consider scaling up the servers in the future if there is potential for user growth.

  • Third-party services:

Some third-party tools or services like maps APIs, payment APIs, SDKs, push notifications, etc., will incur subscription costs. And you may have to pay additional fees for using licensed technologies or frameworks.
