Math Help Needed: "como calcular valor da hora" Without the Headache?

[votije]

Hi everyone,

I'm finally moving away from a fixed monthly salary to a project-based model, and I'm stuck on the basics of como calcular valor da hora.

I know I should divide my desired income by my working hours, but how do you account for hidden costs like health insurance, taxes, and those days when you're just doing admin work?

Every time I try to run the numbers, I feel like I'm forgetting a major expense. Is there a simple formula or a "cheat sheet" that you all use to make sure you aren't going broke?

Thanks in advance.
