How much does it cost to build a stock trading app?

The stock trading app development cost ranges from $15,000 to $200,000, depending on various factors.

If you are planning to venture into online stock trading and broking business, you might be wondering how much it would cost. Any app development cost estimation depends on various factors, including the number and types of features and functionality plus the complexity of the design.

However, to give you a general idea, we have calculated the average cost of developing an online trading app based on the hourly rates of developers in different regions. The formula to calculate the cost is mentioned for your reference:

Development Time x Cost Per Hour = Total Mobile App Development Cost Estimate

Here’s the breakdown of the cost to build a trading app with respect to the app development process. While preparing the pricing range for a trading application, it is of utmost importance to keep in mind the security and compliance aspects and get the budget estimate considering these aspects as well.

App Development Phase Cost Range
Research and Planning $2,000 – $20,000
Design and Development $8,000 – $120,000
Testing and QA $3,000 – $40,000
Deployment $1,000 – $20,000
Maintenance and Support $1,000 – $10,000

Now, let’s explore different scenarios to find out how some of the essential factors affect the cost of stock trading app development.

Scenario 1: Assume 800 hours of total time for trading app development.


Region Average costs (hourly rate) Total cost (Rough estimation)
North America $150 $120,000
Europe $100 $80,000
Asia $40 $32,000

Of course, these are rough estimates, and the actual cost may vary depending on the scope and requirements of your project.

Security in stock finance

One of the most critical aspects of building a stock broking fintech app is ensuring security. Trading of stocks involves massive financial data and transactions that require solid protection from malware, virus attacks, and other hacking tactics. Thus, trading app development cost depends on the robust security measures deployed to safeguard your app and users’ data.

Some of the security features you must consider for your stock broking fintech app are:

  • Encryption: Encryption helps prevent unauthorized access and tampering of data in transit and at rest.
  • Authentication: Authentication helps prevent unauthorized access and impersonation of stock buyers and sellers. You can use various methods of authentication, including passcodes, PINs, biometrics, or OTPs.
  • Authorization: Authorization in the stock trading app controls what users do and see in the Fintech app as per their roles and permissions.
  • Firewall: The firewall is a step for preventing unauthorized or malicious connections and external source attacks.
  • SSL/TLS: SSL/TLS protocol ensures that the data exchanged between the Fintech app and the server is authenticated and encrypted.

The stock market app development cost would increase with each of these security features added. Further, the use of web3 technology in Fintech ensures better security to finance applications. However, to give you a general idea, the average cost of security for a stock trading app could be estimated as per the hourly rates in different regions.

Scenario 2: Assume 200 hours of secure stock market app development.

Let’s break down how the costs vary for different locations when integrating the latest security for your online trading app.

(hourly rate)
Total cost
(Rough estimation)
North America $200 $40,000
Europe $150 $30,000
Asia $60 $12,000

Technology stack to develop a stock trading app

Another essential factor influencing the cost of developing a stock trading app is the technology stack you choose. The combination of several licensed tools, frameworks, languages, and platforms is used to customize a stock broking fintech app. The technology stack is the backbone of any software app development as it decides the performance, scalability, functionality, and maintenance of the final product.

You may look at these exclusive technology stacks to build a stock trading app:

  • MEAN: MongoDB (database), Express.js (backend framework), Angular.js (frontend framework), and Node.js (runtime environment). Hire the best MEAN stack experts for your stock app development.
  • MERN: This stands for MongoDB (database), Express.js (backend framework), React.js (frontend framework), and Node.js (runtime environment). Get the experienced MERN stack professionals for hire on your team to build your trading app.
  • LAMP: This stands for Linux (operating system), Apache (webserver), MySQL (database), and PHP (programming language).
  • Flutter: This is a cross-platform development framework that allows you to build native-like apps for iOS and Android using a single codebase. Hire Flutter Developers to build an efficient trading app at a much lesser time and cost.

The development cost of stock trading app would increase to integrate these technology stacks. Here is a general idea about the estimation of the average cost of using specific technology stacks on the hourly rates.

Scenario 3: Assume 600 hours of MEAN/MERN stack app development.

The complexity of the stock trading app

The final factor that affects the cost of developing a stock trading app is the complexity of the app. The complexity of the app is the number of features, depth of functionality, intensity of design, and integration of APIs or other partnering software tools you want in your stock trading app product. The more complex your app is, the more time and resources it will require to develop, and ultimately, the app budget goes up.

We can classify the stock trading apps into three broader categories based on their complexity:

  • Simple: Simple apps are basic apps with minimal but essential features like user registration/login, profile upload, stock quotes, wish/watch list, stock portfolio, buy/sell orders, and notifications. Such simple apps have a general design and minimum integration with external APIs or services.
  • Medium: Medium apps are advanced apps with some additional features like charts and graphs for analysis, plus stock news and alerts. The app may have social media with chat and feedback, such as ratings and reviews. Medium applications will have moderate design and moderate integration with other APIs.
  • Large: The most complex apps are large apps with the best and unique features like live streaming and video conferencing. You can also have AI/ML algorithms and gamification to improve personalization. Large-size stock trading app development for online trading may also include customization, security tokens, blockchain, and biometrics. Apps with these features would have a sophisticated design and extensive API integration.

Scenario 6: Assume 400 hours for a simple stock trading app, 800 hours for a medium app, and 1200 hours for a comprehensive large app.

Let’s take a look at how the online stock trading app development costs vary with respect to the increase in development hours due to complexity.

Region Average costs of app developer
(hourly rate)
Total cost for a simple app
(Rough estimation)
Total cost for a medium app
(Rough estimation)
Total cost for a large app
(Rough estimation)
North America $150 $60,000 $120,000 $180,000
Europe $100 $40,000 $80,000 $120,000
Asia $40 $16,000 $32,000 $48,000

Support and maintenance cost of stock trading app

This is the most ignored section of costing in any app development. No app or product is useful if it is not maintained appropriately. The importance of app maintenance in helping the mobile app for stock trading to be successful cannot be stressed enough. You should keep in mind that these costs are monthly recurring costs, which will ensure that your stock market app is in good shape and serves the customers well.

Most app development companies follow a standard practice of providing post-sales maintenance support to keep the app up and running. Such support comes from a yearly or monthly contract. You may spare $1000 to $10000 a month for stock broking and trading app maintenance and regular updates.

Location is an essential criterion when you outsource your app development requirements to a professional company. Choosing smartly can help you save big on you online stock trading app development cost.
