In fact, gross profit is only the selling price of the product-direct cost of raw materials = gross profit.

40% gross profit is actually very low (generally around 70%) because of labor costs, management costs, normal operation of gas and water, etc.

Net profit is the last remaining net profit, which is 7-8% for general catering and 15% for fast food.

How much you can actually earn in the end depends on how to control the proportion of other consumption expenditures!
