The gross profit margin of pasta is generally about 61%. Simply put, for example, if you sell a bowl of noodles in 6 yuan, the direct cost, noodles, oil, spices and toppings add up to 2.4 yuan. Of course, the net profit depends on your sales, because this gross profit margin does not include your fixed expenses such as labor, water, electricity, rent and taxes, and the more you sell, the higher the net interest rate will be.
