More like asking “how much is a car?”.
The various kinds of things you need to know are what size pizza . . . how much dough you will use for he crust . . . how much sauce . . . how much cheese . . . you making the dough, or frozen crust . . . what are the prices of the various foods you intend to use in your shop?
Once you get a recipe list, you can figure out what pantry and refrigerated items you will need. Then you can get prospective pricing from food vendors. Then you can figure out the cost to you per unit of the items in your pizzas. Then you can use those numbers back into your recipes to figure out how much YOUR pizza costs YOU to make. Once you get the recipe for one pizza, you can use the area in square inches to develop the recipes for the other pizza sizes you will use.
That is only if you are talking about pure food costs. Labor, occupancy costs, marketing and other junk enter into the equation when you get to talking about menu pricing this pizza you are making.
