For us, making dough is about half the price of buying it. That includes the labor.
Paul, on slow days or in low volume shops there is very little added labor as you point out; the regular crew can knock out a couple of batches. But overall, making dough adds to labor cost. If it means that our afternoon prep guy comes in at 2 rather four that is two hours. During our high volume season we hire a guy just to make dough. He comes in every morning at about 5AM and makes dough. Some days he only has to make 250-300 lbs, but when we are cranking he is making 800 lbs a day. We pay him piece rate so the cost is fixed.
I would estimate that our blended labor rate for dough, counting the time of year when the labor is “free”, the times when we pay labor for all dough making and the times in between at about 10 cents per pizza.
at 1.2 cents per pound for materials plus 10 cents labor our large doughball costs 40 cents all in, which is about half what the frozen doughball of the same size from Rich’s costs.
On 40,000 pizzas per year the difference would be about $15,000 even when you inlcude $4,000 in added labor so making your own dough is a great money saver.
Assuming that you also use the machine to grind block cheese and you save another 10 cents a pound compared to buying shredded which amounts to another several thousand dollars.
Combined, these amount to a 3 point drop in food cost overall. Pretty hard to ignore.
