Web application valuation is a complex process influenced by many different factors, so it is difficult to find two cases in which it would end exactly the same.
The key element is the complexity of the application itself, i.e. the number (type) of functions it should have. Simply put, more features mean more coding, which in turn leads to higher costs. Simple applications that perform one task will cost less than those that are designed for many different uses.
The technology to be used to build it, as well as other related elements, such as the tools used, are also important. The choice of technology may be determined by the project specification - if you do not have any predetermined preferences in this matter, our experts will be happy to help you choose the right solution.
Another aspect is the time needed for software development. It is directly proportional to the costs - the more time the development team consumes the project (and the more experts with experience in a narrow field it requires), the higher the cost of the web application will be.
