What's the lowest amount on which a person can survive on Edinburgh

I will be coming to Musselburg which is near Edinburgh as a international student. I am curious on what's the lowest or budget plan on which someone can live here for.

I am fine with sharing a room on a cheap accommodation even though I am not sure if this is a very good idea.

For food, I will be making them at home. I think i can get my groceries for cheaper using student discounts or going to marts where they sell them for relatively cheaper.

For transportation, either I could buy a cycle or I could buy something called Ridacard which lets me ride Edinburgh Trams which costs about £50 if paid monthly on a direct debit.

It would be helpful if you have some experiences being a international student on a budget plan. I don't know the exact numbers of how much it is gonna cost so it would be helpful if you give me an idea. Feel free to add other cost you might feel are important like the sim card cost, heathcare, and many more.
