What is a mobile banking app?

A banking app is a mobile app that allows customers to access their bank account details and makes transactions directly from mobile devices, such as smartphones or a tablet.

Depending on your customers’ needs, the number and types of mobile banking app features can vary. Deciding on all the features you will build is crucial as they will add up to the cost of your mobile banking app.

These are some of the most basic mobile banking app features:

  • Authorization
  • Viewing card details: current balance and transaction history
  • Making secure P2P transfers
  • Scheduling payments 
  • Paying bills
  • Opening a new account/
  • Ordering a new card

The above features are the bare minimum for a banking app MVP. Nevertheless, to keep up with the growing customer expectation and competition from fintech, banks will need more than that: 

  • QR-code scanning
  • Cashback service
  • One-click payment methods integration (Apple Pay, Google Pay)
  • Booking third-party services
  • Chatbot

Factors determining the cost of developing a banking app?

You can calculate the total cost of developing a banking app by multiplying the number of hours spent on development by the price of an hour of the developer’s work. Note that development cost is just a part of the total budget for the app. The other costs are related to post-release (customer support and marketing), testing, maintenance, and management.

Your cost of developing mobile banking app depends on these 3 factors:

  • App complexity: The more features you build, the more complex your mobile banking app will be, thus the higher its cost. Typically, if you plan to build an MVP first, you will need to pay half the cost compared to a full-scale product.
  • Tech stack: The choice of programming languages, libraries, and APIs contributes to mobile app development costs. Today, most teams choose native languages for mobile banking app development - for example, Swift for iOS and Kotlin for Android.
  • The location of your outsourcing team: The nationality of your outsourcing vendor largely affects the hourly rate you have to pay. A developer in Southeast Asia such as Vietnam or India would cost $20 - $30 per hour, whereas one in the US would ask for $100 - $150.
  • Type of cooperation: The cost of utilizing an in-house team is largely different from that of outsourcing services. Outsourcing is relatively cheaper but it sometimes entails issues in terms of communication and quality.

  • Limited session time

The cost for developing these security features varies greatly based on the time needed for developing them and integrating them with each other development and integration, as well as the type of technology used.
