It really depends on the client. I’ve worked with agencies or businesses that I’ve contracted for on an hourly basis with a set amount of hours per week. But, for projects that are not recurring like brand identity or social media templates for example, I would initially track how long it took the first time I did it, factored in my expenses, and come up with a fixed rate for the project. A designer, who has been successfully running her business, shared a calculator to come up with pricing for profit, and now I use that for my business
