Banking apps development is very popular now, and if you are planning to build one from scratch, the first thing you need to find out is cost of creating an app. In this article, we’ll discover factors contributing to the cost of mobile banking app development and calculate indicative expenses of building a fintech application. 

The number of people making financial operations online is skyrocketing worldwide: at the time when you can pay, purchase or transfer money by one click, brick-and-mortar bank offices have become a thing of the past. This massive switching to mobile banking gives an extra boost to the development of the fintech industry with multifunctional banking apps mushrooming and making this niche quite competitive. 

What is a banking app, and how does functionality determine the app cost?

A banking app is a mobile app where a customer accesses their bank account details and makes transactions directly from the smartphone or a tablet. The spectrum of functions available in such an app depends on a bank a customer is accessing and the functionality of the exact app. 

Below are several classic features provided by most banking apps:

• Authorization
• Viewing card info, current balance and transaction history
• Initiating secure person-to-person transfers
• Scheduling payments 
• Paying bills
• Opening a new account/ordering a new card

Basically, this set of features is enough for banking app MVP and will help you minimize the cost of building an app. However, given the pace of industry development and high competition within the niche, some extra features will help to bring your app to the top positions in the market: 

• QR-code scanning
• Cashback service
• One-click payment methods integration (Apple Pay, Google Pay)
• Booking third-party services
• Splitting bills (enables a group of people to pay their share when they dine together, for example)

What affects the cost of developing a banking app?

Banking app development cost is a core element of the total budget for building and launching a banking app. The way it’s typically calculated is shown in the first part of the formula below: to identify the exact cost of developing a banking app you need to multiply the number of hours needed for the development by the price of an hour of the developer’s work.

The total app building cost also includes post-release costs like customer support and marketing, and additional costs not related to the actual development (analytics, design, testing and management). 

The cost of mobile banking app development depends on four main factors: 

• App complexity. As we said above, the number of features and their complexity directly affect the cost of developing an app. If you are going to build an MVP first, it will cost you half the price compared to the scaled product. 
• Tech stack used in banking and finance app development. The choice of programming languages, libraries, APIs also affects the development cost. Although app developers often choose native languages — Swift for iOS app and Kotlin for Android banking app development – some apps require specific skills and programming languages that go beyond the classic approach (for example, Java is also frequently used in fintech due to enhanced security and cross-platform capabilities, while Ruby on Rails is gaining momentum thanks to high storage database)
• Location of the development team. Just to compare: the average hourly rate of developers in the US is around $100-150, while if you decide to outsource development services in India, you will pay about $20-30 per hour. 
• Type of cooperation. There is a significant difference in costs of making an app if you hire an in-house team or use freelance services. The latter is relatively lower, but working with freelancers implies risks related to the code’s quality. 

Primary features of a banking app: time & costs

Let’s look at the price and amount of time needed to develop core features of a mobile banking app (prices are given for the US market):

Sign-in (authorization)

Every app starts with registration and authorization. The authorization process should meet security standards (passwords or biometrics checks like Touch-ID or Face-ID). 

Access to card details

Users should be able to quickly access card numbers, balance, owner’s name, payment system, and account details. Moreover, this feature can include card-related services, such as card re-issuing.

Transactions and payments

The process of sending and receiving funds should be intuitive, simple and secure. Users are usually asked to confirm transactions either by biometric verification, an SMS with a code or by typing their password.

Approximate time required: 480 hours

Approximate cost: $48000-72000

Transaction history

Users should have access to the whole spending history from all the connected bank accounts. The more detailed the report is the better user experience you are getting in return. 

Spending analytics

Mobile banking app developers create this feature to help users to analyze financial behavior and set financial goals. The functionality often includes budget categories, customized reports, and saving goals. Here you should work a lot with a UX designer to implement really descriptive charts and diagrams and it can influence the cost of designing an app.

Notifications

This is an essential part of mobile banking app development, allowing to notify users about transactions, required authorization or special offers. 

Approximate time needed: 120 hours

Approximate cost: $12000-15000

In-app chat with customer support

Easy way to quickly get in touch with technical support, chatbot, or a personal bank manager to clarify any issues arising.

Let’s summarize the basic costs of banking app development:

Basic feature	Approximate time  needed	Approximate cost
Sign-in	480	$48000-72000
Access to card details	240	$24000-36000
Transactions and payments	480	$48000-72000
Transaction history	240	$24000-36000

TOTAL	2280	$228000-342000

Extra features of a banking app: time & costs

Since time and the approximate cost of building app with basic features is identified, let’s review some additional features you can add:

QR-code scanning

According to Statista, more than 27% of users in the US and UK preferred QR-code as a payment method in 2020. Include QR-code in your banking app development feature list to ensure fast and secure payments.

Cashback service

It is one of the users’ favorite features that allows getting back a certain amount of money spent. Mobile banking app developers usually set several cashback categories and allow placing returns on a separate account. 

One-click payment methods integration (Apple Pay, Google Pay)

One-click payment methods are taking over the world, that’s why the integration of Apple Pay and Google Pay is the key step to high payment conversion and maximum user-friendliness. 

Approximate time needed: 480 hours

Approximate cost: $48000-72000

Booking third-party services

Another convenient feature, which is often included in mobile banking app development to uplevel the app. By adding access to the third-party services, you enable users to buy tickets, book hotels, and so on without leaving the app. 

Approximate time needed: 480 hours

Approximate cost: $48000-72000

Splitting bills

“Splitting bills” feature makes routine transactions more convenient: no debt repayment when you are having dinner with friends in restaurants, everyone covers their share. 

ATM and office locations

This feature is set to make the search of ATMs and bank branches nearby easier. To enable it, mobile apps developers integrate Google Maps or Apple Maps for Android or iOS, respectively. 

Approximate time needed: 120 hours

Approximate cost: $12000-15000

TOTAL	1920	$192000-282000

Security costs 

A high level of security is a top priority for mobile banking app development. We recommend you to make a separate section in your mobile app development roadmap devoted to security issues of the future banking application. So, using the latest technologies to ensure the security of transactions and data stored in the app is another item of expenditure within the development process. Here is the list of measures that will help you to enhance banking app security: 

• Usage of biometrical data
• One-time passwords to confirm user’s identity
• Risk-based authentication
• Implementation of a password check (to avoid the situation when it’s too short and simple)
• Limited session time

Keep in mind that the cost for different security features significantly varies depending on the time needed for development and integration, as well as the type of technology used in a concrete feature.
