Do you see how many features and options a mobile banking app can offer to your customers?

All this requires a solid strategy, execution plan and, of course, investment.

Answering the question of how much an average price of a banking mobile app has encouraged us to breakdown the costing structure of an average mobile app so you can understand why it costs a fortune to build one.

How is the Fee Segmented and Determined?

No mobile app has a fixed development cost. Most mobile app development agencies in London charge the client by the hour. Others also settle in for a fixed development price; however, the flexibility margin for the build-up of the app is relatively small. You can’t get much done in a fixed budget. However, to average out an idea for users who are interested in building something similar to the NatWest mobile app, consider these factors:

Determine the scope of the mobile app Commonly, a mobile app which adjusts the greater number of features is more likely to have a large size. If you ever get the chance to have a detailed discussion with one of the developers at a mobile app agency firm, then you will realize that each feature requires consistent testing until the code behind the feature is mastered to perfection. This relatively results in increasing the development time and hence, adds up to the time required for the complete mobile app to be built.


Determine the man-hours required for the build Once you’ve finalized the scope of work, you’ll have to calculate man-hours mobile app developers will put in to build the perfect banking mobile app. The team which was handed over the NatWest’s project had well-categorized designers and developers working at the back-end day in and day out. The time these resources spent on designing building the app is determined as man-hour spent. You need to identify how much time each of your developers, designers, quality specialists and project managers are going to invest in completing the app.

Customized Features & Modules Every great mobile app idea is born out of necessity. And there are a ton of hours of unique and innovative features that might pop up in the mind of the client. When clients pitch their idea to a mobile app development agency, their agenda is to develop a creative app, which is completely unique and stimulate a sizable number of users from the intended audience to use it.

In this quest, clients often feel the need to push as many features as possible in the app. Doing this results in increasing the development time and costs. Therefore, whenever you’re planning to get an app developed to make sure you focus on the core features that will go in the app and avoid the bells ‘n’ whistles or get them incorporated in future builds of the app.


Testing & refinement associated costs – Some mobile apps require less testing while others require a good amount of continuous testing. Static mobile app design has to pass through a less number of testing phases whereas, a dynamic mobile app with custom animation will require more. Static mobile apps are relatively cheaper to build. But when you are designing a dynamic mobile app, you need to address the requirements, compatibility, interface, security, low-level resources of the app. Before it was launched, the NatWest app went through a number of open and beta testing phases which incurred costs altogether.


Set the project time-frame – When designing a mobile banking app such as NatWest, make sure to keep your project timeline as flexible as possible. Such apps are feature intensive and may require a new feature to be introduced and added as the app idea progresses. Project time-frames are incredibly important because you might’ve to hire extra staff or pay overtime.

What is the Cost for Building an App like the NatWest Mobile Banking App?

Generally, simple app designs for the banking industry that merely provide a window where the bank’s internet banking page is displayed costs around $20,000 to 30,000. We at Branex, have evaluated that the basic banking mobile app goes through a number of complicated steps before it is standardized.

You need a team who knows what the needs of users and how the bank is positioning itself to stand out from the crowd. The team includes back-end and front-end developers, UI designers who’ll craft an impressive interface, UX engineers ensuring the app offers an intuitive and streamlined user experience and an efficient product/project manager who’ll ensure the whole development process goes as planned, resulting in a high-performing application being developed.

The numbers break down to about 120 hours of work per week with an average development time of around 10 weeks for a mobile banking app to be built. The time specified is basically the time which will then subsequently be distributed among different teams associated with the development of the app. It is a cumulative time frame. However, if you are planning to get it more customized just like the NatWest online mobile banking app and get the marketing done as well, this number can easily go north of $150,000.

In the end…

So there you have it. In this piece, I’ve summarized the aspects and features that any company from the banking industry should keep in mind when finally deciding to go for developing a mobile application to facilitate the customers. Just like any channel that businesses exploit to better connect with and serve their customers, a mobile app is another channel that is here to stay and will yield maximum results.

NatWest is a shining example for the players in the banking industry that if you play the mobile card correctly then you too can be the recipient of the next British Bank Award in the banking app category.
