I'll take a guess and will probably be wrong. If you are trying to figure out total cost, you need to add labor and overhead if you are trying to figure out what it costs for a pizzeria to make it vs. you at home. However their costs of product used is lower than what it would cost you since they buy in volume. Anyway, I read that some pizzeria's, not all, try to keep their resale at 3.5 times their cost. So if they are selling for $10, their cost should be $2.80 or something like that. That doesn't include their overhead, just the cost of ingrediants used to make the pie.. For me at home, my dough costs under a dollar, the sauce is probably around .50 at most, cheese is around 1.50-2.00, pepperoni's are a penny each so if you put 20 on, that's 20 cents...you can figure out the rest depending on what you put on it. My cost if different than everyone elses I guess..but that's mine, around 3.50-4.00
