Rates for software development services can vary from as low as $10 and increase up to $850/hour or even higher based on the required expertise, experience level of the specialist, and location. Note that the Eastern Europe (Ukraine) IT outsourcing region provides the greatest price-quality ratio of $30-$50/hour, level of tech skills and practices, and a large pool of experienced programmers. Generally, the software concept you need to develop with its business and technical requirements directly correlates with the number and the cost of the software development services. The key factors and elements that influence the final cost of the whole software development service include aspects such as type, location, and hourly rates of the selected IT vendor, a number and complexity of the functionality, design complexity with extra branded elements (graphics, imagery, animation), complexity of the project infrastructure (its integrations, APIS, elements), a number of the platforms you target (iOS, Android, Web), and so on.
Besides, different types of software development services cost different amounts, and the combination of all these services makes up a total software cost. In general, the work of a UX/UI designer ($30) costs less than a senior iOS developer ($50-60). Besides, the rate for software development services depends on the seniority level of a programmer, level of expertise, and knowledge, and thus, has different prices.
In some cases and in some IT companies, the price for software development service can be fixed. However, in most cases, IT vendors use Times & Material pricing model. This principle is based according to the hourly rates of the necessary resources and time to complete this work. This gives higher flexibility during the development process to create great final software.
