The cost of hiring a Ruby on Rails developer can vary depending on a number of factors, including the developer's experience, location, and the complexity of the project.

In general, developers with more experience will charge more. Developers who are located in high-cost areas will also charge more. And, of course, the more complex the project, the more it will cost to develop.

However, there are some ways to save money on hiring a Ruby on Rails developer. For example, you can hire a freelancer or a remote developer. You can also look for developers who are just starting out and are willing to work for less.

Here are some tips for finding a Ruby on Rails developer who is a good fit for your project and your budget:

Define your project requirements: Before you start looking for a developer, take some time to define your project requirements. This will help you to narrow down your search and find a developer who has the skills and experience you need.
Create a budget: Once you know what your project requirements are, you can start to create a budget. This will help you to stay on track financially and avoid overspending.
Research different developers: Once you have a budget, you can start to research different developers. There are a number of online resources that can help you to find qualified developers, such as Upwork, Fiverr, and GitHub.
Interview potential developers: Once you have found a few potential developers, you should interview them to see if they are a good fit for your project. This will give you a chance to ask questions about their experience, skills, and rates.
