The development costs for a Ruby on Rails application depend on a large number of factors. Some developers and companies prefer to charge the client by the hour. In other cases, the developer and client may rather come to a total cost for the project. In this case, the developer may estimate the time it would take them to complete the development. This is taken into consideration to give the client the price for the entire project.
When development services are charged based on time, the developer will usually charge around $50 to $150 per hour. The average developer usually prices a whole project between an amount of $1000 and $10000. There are, of course, high-end developers as well - where prices often go as high as $50000 for the project.
Factors that generally affect the estimated costs of a project include:
The size and stature of the development company. Larger companies tend to charge higher prices.
The location of the company or developer can also play a role.
The amount of time available for the completion of the project is taken into account. If a project is urgent, it will likely cost more.
Projects that are very complex will take more time and effort to complete, which also means they will cost more.
