The calculation formula of restaurant cost accounting method is as follows:

1. Cost of raw materials consumed in the current period = raw materials purchased at the beginning of the period+raw materials purchased at the end of the period. Cost price = purchase price/(yield * feeding standard (quantity). Gross profit margin = (sales price-raw material cost)/sales price *111%. Sales price = raw material cost /(1- gross profit margin). Sales price = raw material cost+mark-up. Markup rate = gross profit margin /(1- gross profit margin).

2. raw material value = wool value-(unit price of inferior material quantity+unit price of waste quantity). Direct cost: the cost that the restaurant directly uses to make dishes or services, including the cost of ingredients, staff salaries, rent, utilities, etc. Indirect costs: Other costs related to restaurant operation, such as advertising fees, maintenance fees and insurance fees.
