selling price * (1-gross profit margin) = cost amount.

it is impossible to calculate the cost of dishes correctly if only the purchase price is used. Considering the consumption of ingredients in the cooking process, the purchase cost must be combined with the food cost to calculate. The specific execution sequence of cost calculation is as follows:

1. Get the standard yield. The average weight of raw materials that can be provided to guests after cooking is the standard yield.

2. Then calculate the food cost. For example, the standard yield of 9kg beef at the time of purchase (purchase cost 31 yuan /kg) is 6KG, the production cost is 31 yuan× (9 kg ÷ 6 kg), and 1kg is 45 yuan.

3. Next, calculate the standard cost of one person. Based on the cost of dishes, calculate the cost of dishes for about one person. For example, a single serving of steak is about 211g, and 1kg of beef can get 5 servings. In the above example, it is 1kg45 yuan, so 45 yuan ÷5, and the cost per person is 9 yuan.

4. Then, it is necessary to calculate the comprehensive cost of materials for making a dish. Although it is impossible to calculate all the ingredients, it is necessary to calculate the cost of high-priced meat, fish and shellfish, fresh ingredients and so on. According to the business type, the cost rate target is 31%. In order to achieve the target cost rate, relevant procurement, cooking and sales are necessary.
