"People put food first"-the general probability of doing high-end catering is that you will not lose money in one year, return to your capital in two years and generate income in three years. The most important thing is to create a brand in the first year, and the investment is relatively large, mainly for gross profit control, which is converted by yourself before investment.

there are many formulas for calculating gross profit margin, mainly including the following:

gross profit = ∑ (single product operating income-single product operating cost) (Formula 1)

=∑ (single product sales × single product gross profit) (Formula 2)

=∑ (single product sales × single product gross profit) (Formula 3)

where: < p

Formula 2 pursues:

1. Pursuing the maximization of single product price;

2. Pursue the gross profit of a single product without paying attention to its gross profit level.

Formula 1 pursues:

1. Customers consume products with high unit price, so that customers can spend as much money as possible.

2. The gross profit margin of products consumed by customers is the highest, that is, the price difference accounts for the largest proportion of income, not just the price difference.

Formula 3 pursues:

1. Customers consume as many items as possible.

2. The gross profit of single product consumed by customers is the largest.

Obviously, the goals pursued by Formulas 2 and 3 and our goal of maximizing profits are not feasible in practical application, because:

1. The number of customers' consumption products is generally about 1.2-1.5 times of the number of people who eat, and they can't finish eating more, which is not in line with the increasingly recognized concept of "not wasting" consumption, and is limited by reality.

2. Maximizing the absolute gross profit of a single product will mislead us to choose those products with high unit price but low gross profit rate, which will affect the overall gross profit level. For example, 51 yuan's gross sales profit is 31 yuan, which is more in line with our interests than 41 yuan's price of 111 yuan. Because the customer's second consumption habit is that there is a basic budget for the total consumption price before consumption, there is generally not much room for upward fluctuation, unless there is a very attractive product, and there is a decision on the amount of consumption, there may be a greater fluctuation, which is generally not much.

Special reminder: Do not use the commonly used formula "Gross profit = ∑ (single product sales × single product gross profit)" as the theoretical basis for thinking and decision-making, which will mislead our decision-making and be a trap.
