What does the hourly rate fee method primarily depend on?

The hourly rate fee method primarily depends on the time spent on the project by the designer because this approach calculates fees based on the actual hours dedicated to completing the work. Designers track the time they invest in various tasks and bill clients accordingly, ensuring that the compensation reflects the effort, resources, and expertise applied to the project.

This method allows for flexibility in pricing, accommodating projects that may evolve in scope or complexity over time. By focusing on time, clients are often provided with a more transparent billing process, as they can see how their budget correlates with the designer's work hours. This is especially useful for projects where the overall extent is uncertain, making it a practical choice for many interior design assignments.
