Anytime you want to work on an app idea, it’s important to know the cost you can expect to turn your idea into reality. There are currently three million apps in various app stores, and they all have been developed with different budgets. If you call several app development companies to figure out the cost of a given project, you can expect to get very different answers. It may be impossible for you to know which number is most appropriate. It takes time and effort for both the Idea Owner and the App Developers to come up with the most appropriate cost.
But, what if there was a way to know the formula and process used by Developers to estimate the cost of an app? If you can know and understand the formula used by Developers, you can have a sense of the appropriate cost and then compare it with estimates provided. Many app development projects have the following models and cost can be divided into these models
1. Universal Formula to Calculate the Cost
Simpalm’s team has used its seven years of experience to come up with a Universal Formula that anyone can use to estimate the cost of an app. Here it is:
The hours required to build a mobile app depends upon a variety of factors including the size of the app, complexity, design requirements, the development process, backend server, maintenance, and several other related factors. A developer’s hourly rates depend upon the location and experience of the developer. An offshore vendor can charge between $15 and $25 per hour, a full onshore company can charge $70 to $150 per hour and a company with Onshore/Offshore resources may charge between $30 and $50/hour.
2. Determine the Size of Your App
To make it easy for you to understand how much your app may cost, you should first determine the size of your app. Here is a quick tip for you to know the size of your app:
- Small app: it should have around 6-10 unique screens.
- Mid-sized app: It should have around 20-25 unique screens.
- Large app: It should have 40-45 unique screens
A unique screen is something that is not repeated in the app with minor changes. It takes time and effort to design and develop a unique screen in the app. Once you determine the size of your app, you can have a better idea in terms of how much it might cost by following the cost factors defined in this blog.
3. Estimate the Design Cost of an App
It is very important to create a thoughtful UI/UX for the application. It does not matter if your app is small or big, this is the most crucial step of app development. It takes time and money to do UI/UX well, however, it will save you cost and time in the long run. By having well-defined UI/UX requirements for the app, you can avoid cost escalation during the development of the project. The design process generally involves three key tasks:
- Gather and understand the requirements in a Word document.
- Create the layout and flow of the app using a wireframe tool.
- Show the UI Design of the app using Photoshop, and selected themes, colors, and fonts.
Requirement gathering and wireframing are generally executed together. The graphical design is done once wireframe and requirements have been defined. Developers will use a wireframing tool like Balsamiq or Proto I/O to create the flow and screens of the app. Here are my estimated hours for the design of an app in three different sizes. The table also shows the cost of different types of vendors. Also, you can use this table to estimate the design cost of the project.
4. Estimate the App Development Cost – Native Approach
You can build your app using the Native iOS and Native Android Approach. Which is one of the best approaches to build high performing apps. You will need two separate developers to build your app on both iOS and Android platforms. Native android developers will be needed for the Android app and native iOS developers will be needed for iOS App. If your app does not need a backend server, it will cost you less to get the app developed. You can use this Table to calculate the estimated time and cost to develop the app for one platform (iOS or Android). If you want to estimate the cost for both iOS and Android, just multiply the costs in this table by two.
5. Estimate the App Development Cost – Cross-Platform Approach
Instead of using a native app development approach, you can also use the cross-platform app development approach to build your app. In this approach, you don’t need two developers to build an app for iOS and Android. You can use one developer to build apps for both the platform. Some of the popular cross-platform frameworks available these days are: React Native and Xamarin. You may not get performance as good as a native approach, but in many cases, it turns out to be a good option. You may not be able to reduce the time by half compared to the naive approach, but it can be in the range of 70%-75% of the native approach for both the platforms. You can use this Table to calculate the estimated time and cost to develop the app using a cross-platform approach.
6. Estimate the Cost of Backend Development
Most of the applications these days do require a backend, typically to be able to save data on a backend server, and to be able to fetch it again for later use. Whether it is a social media app, news app, nutrition app, productivity app, or on-demand app, you will need to build a backend server so that the app can function. Any app that needs to allow one user to access another user’s data, will need a backend server. Building backend adds cost to App Development. As a leading app development company in Wisconsin, we recommend using Amazon AWS or Azure, a cloud-based backend so that the cost of development is less and maintenance will be easier. You can use the following table to estimate the cost of backend development an app. Here is a table that gives estimates on app and backend server development:
7. Estimate the Post Production Cost
Once you launch the apps on stores, you may incur several additional costs. For example:
- Cost to maintain the app in stores. If, for example, iOS or Android comes up with an update causes your app to dysfunction, you’ll need to address that. Typically, OS updates do not affect all apps, but statistically they do affect 2-5% of apps.
- Cost to add more features to your app. You may come up with additional features that need to be added to your app.
- Cost to market the app. This is not related to development, but still you will want to know this number.
- If you want to allocate a budget for your first year of support, you can typically set aside 10% of your development cost for the support and maintenance. For example, if it cost $20K to develop your app, you want to budget $2000 for first year of support.
8. How can you reduce the cost of your app development
You always want to build your product at minimum cost to be more successful with your idea. There are always ways to reduce the cost of your app development. Simpalm is one of the top app development company in Chicago, and has developed several mobile apps at a minimal cost. Here are some tips you can follow to reduce the cost of your app development:
8.1 One Platform Vs Two Platforms
If you want to build the app for both the iOS and Android platforms, then it will cost you almost double that of building an app for one platform. As a startup, you just want to start with one of the platforms and launch it to capture the market reaction. iOS is the most preferred platform in the U.S. when launching an app for only one mobile platform. Remember Instagram? They initially came out with an iOS app only, yet started with millions of users. If your app is done right, you will gain a market just with one platform and will then be able to replicate your success on other platforms.
Cost of App for Two Mobile Platforms = 2 X (Cost of App for one Mobile Platform)
8.2 Native Vs Cross-Platform Approach
Cost of Cross Platform (iOS+Android) App < Cost of Native (iOS+ Android) App
8.3 Do Initial Wireframes and Requirements Yourself
You can reduce the design cost by doing initial work yourself. The major part of design work is writing requirements and doing screen sketches. You can find several sample requirement documents and templates that you can use to write your app functions and features. You may not have to be fully professional in writing these requirements, it is better to have something than nothing. If you provide a baseline requirement document to your designers, then it will reduce the number of hours needed to write it. Same goes for the wireframes, if you can do some sketches on a piece of paper which shows the screen flows and functions, it is easier for the designer to visualize the app flow and functions.
8.4 App Development Agency Vs Freelancer
It is always less expensive to have a freelancer work on the project than an app development agency. App development company would charge you more but they are more committed to completing your project and a vast pool of talent. Working with freelancers has its own risk, you totally dependent upon the freelancer. If they lose interest in your project or find something more interesting, they may just leave your project and you will be stuck. If you have some idea about product development and project management and can find good freelancer from sites like upwork, you can go for freelancer approach.
