How much does it cost to pay someone to build an app? In eastern Europe mobile developers charge between $23 – $35 per hour. The average cost of mobile app is 50k$ e.g. two developers for 6 month.
Price you pay for app development depends on the work background structure (WBS). WBS is a hierarchical decomposition of a project’s work, breaking it down into smaller, more manageable components which can be precisely estimated. WBS gives an idea about how many developers will be needed.
Developers are not needed on the first phases of the project. But you will need project manager, business analyst and designer. After 2-4 weeks of project initiation, comes the build phase, when all the developers program app’s features, designer and business analyst are not needed anymore. After build is complete test phase takes place. The last phase is project acceptance testing, when you as a customer accept or decline application features. The number of developers during this phase reduces usually to 1-2 persons.
Thus you have a resource plan – a big table, columns are project weeks, rows are development resources: programmers, quality engineers, business analysts, project manager. If the resource is used that week you write for how many hours in that cell (0-40). By calculating the sum of all hours and multiplying it on the resource hour rate you get total project cost.
