28%-33% is normal.

The cost accounting of catering enterprises is different from that of industrial enterprises, which only includes raw material costs and combustion costs. In addition to the cost of raw materials and fuel, catering enterprises have to pay a lot of operating expenses such as labor, water and electricity, material consumption, rent, depreciation, management expenses and financial expenses, in addition to paying business tax at the rate of 5.5% of turnover.

Therefore, gross profit is net profit after deducting the "three fees" and business tax. In this way, in the end, the "net profit" of catering enterprises is far less than expected.

sales gross margin = (operating income-operating cost) ÷ operating income× 111% cost gross margin = (operating income-operating cost) ÷ operating cost× 111% Generally, only sales gross margin is calculated, and cost gross margin is only used to calculate the operating profit generated per unit cost.

Gross profit refers to the total amount calculated in currency, and gross profit rate is a ratio. Gross profit margin is equally important, because it can let entrepreneurs know the profit trend of enterprises, and the profit trend is very critical, because many enterprises in financial crisis often show a trend of increasing gross profit margin but decreasing gross profit margin. The calculation formula of gross profit rate is as follows:

gross profit/sales = gross profit rate

First, we can increase the price of products. Second, it can reduce the production cost of products. Of course, both are easier said than done. Increasing the price of products may lead to a decline in sales. If sales drop sharply, the total income is likely to be insufficient to cover operating expenses. Increasing prices also requires a deep understanding of inflation rate, competitive factors, the basic supply and demand relationship of products, and so on.

another way to reduce the cost of raw materials is to find suppliers with lower prices. However, if the quality of raw materials provided by the other party is not good enough, then you have to sacrifice the reduction in the quality of raw materials.
