How do i Save money to Move out of My Parents' when i owe Loans and Car?

I’m in my early 30s. In my culture, this is normal. kids live with the parents like this. But i’m tired of it and i don’t like my parents nagging on me and controlling my life. I want to move out. And i also have to move out if i ever want to be independent and also get married.

How do i save and how much do i save in order to move out?
Add the fact that i owe 400 monthly for car payments( and there’s still about 17000 dollars left) and I have a 20,000 school loan( still owe 20000) for which i pay from 200 to 300 a month.
