The cost to develop a neobank app in 2025 usually starts at around $40,000 for a basic version and can go beyond $300,000 for a full-featured one. The final cost depends on the design, platform (like Android or iOS), the number of features, and where your developers are located. A simple app with basic banking options costs less. But if you want features like spending insights, budgeting tools, or third-party services, the price will be higher. Planning everything before starting the project helps control the neobank app development cost and avoid spending more than needed.
